AG1 Review - Is AG1 Worth It?

AG1 Review And Testing

October 18, 2024

Welcome to our AG1 review (also known as Athletic Greens). After 18 months of thorough assessment up to October 18th, 2024, we've re-evaluated our findings on AG1 (commonly referred to as Athletic Greens). This product claims to offer a simple solution for meeting daily vitamin and mineral requirements, promising to fill the nutritional gaps often seen in modern diets with just one scoop. However, the extensive ingredient list and reliance on a proprietary blend raise questions. We assess these issues and we'll share our firsthand experience. We'll also discuss other green powders that could potentially be a better fit for your nutritional needs.

Overall Verdict



  • Transparency Issues: AG1 uses proprietary blends that obscure the exact amounts of each ingredient, preventing users from verifying whether the product contains effective dosages.
  • Ingredient List Overload: The extensive list of 75 ingredients in AG1 suggests more of a marketing focus than functional benefits, with many ingredients potentially present at trace levels - and certainly in sub-therapeutic amounts.

  • Questionable Dosages: Without transparency, it's difficult to determine if AG1’s ingredients are provided at clinically effective levels. It's highly likely many listed ingredients are underdosed despite the impressive-sounding list.

  • Taste Issues: Many users report that AG1's taste is overly sweetened by stevia, which can be off-putting, likely an attempt to mask the flavors of its numerous ingredients.

  • Cost vs. Benefit: The very high cost of AG1 coupled with the lack of dosage transparency leads to questions about the supplement's value for money relative to its actual health benefits.

  • Recommended Alternative: The top rated greens powder in our tests, Supergreen Tonik, is in our view a better alternative, due to its transparent labeling, comprehensive formulation and clinically supported ingredient dosages. We experienced improvements to digestion, cognitive performance and sleep.

What Are Greens Powders?

Greens powders have become a highly sought-after supplement within the nutrition and wellness sector, designed to enhance the daily intake of essential nutrients. These powders are a blend of concentrated vegetables, fruits, algae, and herbs, offering a wide spectrum of vitamins, minerals, and antioxidants. The primary objective behind their consumption is to bolster overall health, potentially improving energy levels, supporting detoxification processes, and contributing to a more nutrient-dense diet, particularly for individuals who struggle to consume an adequate amount of fresh produce daily (1).

What to Look For In Greens Powders

With a vast array of options available on the market, identifying a high-quality greens powder requires careful consideration. First and foremost, product transparency is critical. Consumers should opt for supplements that clearly list each ingredient and its amount, steering clear of those that use 'proprietary blends.' This transparency ensures users can verify the presence of scientifically-backed dosages of nutrients, which is vital for reaping the intended health benefits (2).

Clinically proven dosages are another cornerstone of a reputable greens powder. This entails that the nutrients included have been tested in research settings and demonstrated to offer health benefits at specific dosages. Such evidence-based formulations are more likely to deliver on their promises of improved health outcomes (3).

Taste and palatability cannot be overlooked, considering these supplements are meant for daily consumption. A greens powder that is difficult to consume due to its taste may discourage regular use, thereby diminishing its potential health benefits. Finding a product that balances nutrient density with a pleasant taste ensures a sustainable addition to one’s daily routine (4).

Greens As Part Of An Overall Nutritional Strategy

Integrating greens powders into your nutritional strategy should aim to supplement, not substitute, the intake of whole fruits and vegetables. Whilst greens powders can play a crucial role in bridging nutritional gaps, particularly in diets lacking in fresh produce, they are best utilized as part of a broader, balanced diet. This approach acknowledges the importance of consuming a variety of nutrient-rich foods and supplements to support optimal health (5).

Greens powders offer a practical solution to augment, rather than replace, the consumption of whole foods. When used in this way, greens powders can contribute effectively to a well-rounded healthy diet.

What Is AG1? 

Athletic Greens AG1 is marketed as a comprehensive dietary supplement designed to support overall health through a single daily scoop. It contains a blend of 75 vitamins, minerals, and whole-food-sourced ingredients aimed at optimizing nutrient intake and addressing potential dietary deficiencies. Each 12g serving provides essential nutrients, including a robust profile of vitamins A, C, E, and B-complex, as well as minerals like zinc and selenium. AG1 also includes probiotics and enzymes to enhance digestive health and absorption. Formulated to aid energy levels, immune function, and recovery, AG1 is tailored for individuals seeking to bolster their daily nutritional intake conveniently.

AG1 Marketing And Endosements

AG1 has leveraged high-profile endorsements to boost its visibility and credibility. Prominent figures such as Joe Rogan and Andrew Huberman are not just endorsers but are reportedly compensated with significant endorsement fees alongside commissions on sales generated through their platforms. Such endorsements are potent marketing tools, as they often convey a sense of trust and effectiveness to potential consumers.

The involvement of celebrities like Hugh Jackman, Cindy Crawford and Lewis Hamilton as investors further amplifies the product's reach and appeal. These figures are utilized not just for their financial backing but more strategically in marketing campaigns to attract a broad audience. Their association with AG1 suggests a level of product quality and desirability, intending to resonate with health-conscious consumers who admire these personalities.

This marketing strategy, while effective in garnering attention, also raises questions about the product's intrinsic value versus its perceived value driven by celebrity association. Potential users should consider whether AG1’s benefits are reflective of its marketing claims or primarily the result of celebrity endorsement-driven popularity. Such endorsements can significantly influence consumer expectations and decisions, underscoring the need for discernment in evaluating the actual nutritional and health benefits AG1 offers compared to other similar supplements on the market.

AG1 Transparency And Dosing Issues

Ingredients and How They Work

Athletic Greens AG1 contains a diverse mix of vitamins, minerals, plant extracts, and probiotics in each 12-gram scoop. The product claims to support various health aspects including immune function, energy levels, and digestive health. However, the utilization of a proprietary blend raises significant transparency and efficacy issues.

Ingredient Transparency and Proprietary Blends

AG1 employs a proprietary blend, which obscures the specific amounts of each constituent, preventing consumers from confirming whether these ingredients are present in clinically effective dosages (6). This lack of transparency is concerning, as it does not allow users to assess the potential effectiveness of the product based on its ingredient composition.

Issue of Underdosed Ingredients

Given the broad range of ingredients listed in AG1, many are highly likely to be underdosed compared to dosages recommended in clinical studies. For instance, clinical evidence suggests that adaptogens like ashwagandha and rhodiola require substantial amounts to achieve their known stress-reducing effects, amounts unlikely to be present in a complex blend (7,8).

With claims of 75 different ingredients in a modest 12g scoop, it's clear that most ingredients are only present in trace amounts and are therefore unlikely to have any meaningful nutritional benefit.

Marketing Claims vs. Nutritional Reality

The marketing of AG1 heavily emphasizes the extensive list of ingredients as a key selling point. This can be misleading, suggesting a more is better approach, where the sheer number of ingredients overshadows the need for effective dosages (9). For example, the inclusion of digestive enzymes and probiotics such as Lactobacillus acidophilus and Bifidobacterium bifidum is promoted, yet without specifying amounts, it's unclear if these are added at levels that would provide the digestive benefits claimed (10).

AG1 contains a variety of ingredients that could potentially offer health benefits, but the proprietary blend and likely underdosing raise significant concerns about its overall efficacy. For consumers considering this supplement, these issues highlight the need for greater transparency in the supplement industry. Prospective users should critically evaluate the claims made by AG1 against the backdrop of ingredient transparency and dosage adequacy to determine if it aligns with their nutritional needs.

AG1 Pros and Cons

Pros

  • Broad Ingredient Profile: AG1 includes a wide range of vitamins, minerals, and antioxidants, aiming to support overall health through a single daily scoop.
  • NSF Certified for Sport: This certification ensures that AG1 is free from banned substances, making it safe for athletes and those concerned about clean supplementation.
  • Some Positive Initial Impact: Some users reported improvements in energy levels and a general sense of well-being shortly after starting AG1.

Cons

  • Proprietary Blend: AG1 uses a proprietary blend, which means they intentionally hide the exact amounts of each ingredient. This lack of transparency makes it difficult to assess the potency and value of the product.
  • Very High Price: The cost of AG1 is very high compared to other greens powders.
  • Potential for Nutrient Redundancy: For individuals already consuming a balanced diet, AG1 might provide nutrients in excess of their daily requirements, raising further questions about AG1's cost-effectiveness.
  • Allergen Concerns: With a wide range of ingredients, including potential allergens like soy, AG1 might not be suitable for everyone, particularly those with specific dietary restrictions or sensitivities.
  • Taste: While some found the flavor to be pleasant compared to other greens powders, many testers haven't enjoyed it due to the inclusion of a significant and possibly excessive amount of Stevia.

AG1 Marketing Claims

AG1 Marketing Claims Detailed Analysis

  1. "75 ingredients designed for balance, focus, health, and energy": AG1's formula includes a complex array of 75 different ingredients such as vitamins, minerals, enzymes, probiotics, and adaptogens. These components are generally associated with supporting overall well-being and enhancing physical and mental performance. However, without specific dosages provided due to the proprietary blend, it’s challenging to assess their potency and effectiveness in achieving the stated benefits of balance, focus, health, and energy.
  2. "More-in-one nutrition": AG1 claims to streamline nutritional supplementation by combining the effects of multiple products into one. This assertion suggests convenience and comprehensive support. However, the real impact of such a formulation heavily relies on the presence and proportion of clinically significant dosages, which remain undisclosed in AG1’s proprietary blend.
  3. "Mental performance": Ingredients known for their cognitive benefits include B vitamins, such as B12 and folic acid, which help reduce fatigue and support cognitive function (11,12), and adaptogens like Rhodiola that are reputed to enhance mental clarity and focus under stress (13). However, the effectiveness of these ingredients depends on their amounts, which are not transparent in AG1.
  4. "Enduring energy": The claim that AG1 aids in energy sustainability may be supported by the inclusion of ingredients like B vitamins, which are crucial for energy metabolism. The product provides a substantial percentage of the daily value for these nutrients, suggesting a potential benefit in this area (14).
  5. "Heart health": Key nutrients involved in heart health include magnesium and vitamin E (15). AG1 includes these ingredients, yet without clear dosages, it's uncertain if they are present in amounts that can significantly impact heart health.
  6. "Immune defence": With a solid dose of vitamin C and zinc, AG1 seems capable of supporting immune function, given these nutrients are well-documented for their roles in bolstering immunity (16).
  7. "Gut-Friendly Bacteria and Fibre": The inclusion of probiotics like Lactobacillus acidophilus and dietary fibers supports digestive health, but the effectiveness is dosage-dependent. The lack of specific probiotic CFUs and fiber grams again raises questions about potential benefits (17).
  8. "NSF Certified for Sport®": This certification indicates that AG1 meets strict standards for quality and does not contain banned substances, lending credibility to its safety profile.
  9. "Optimised for flavour without artificial sweeteners": Using stevia, a natural sweetener, suggests an attempt to make the supplement palatable without synthetic additives. This choice reflects current trends towards cleaner labeling but does not necessarily impact the nutritional efficacy. Some people do however find Stevia unpalatable and whilst not artificial, Stevia cannot claim to be natural due to the artificial extraction process used in its production.
  10. "Trusted by leading scientists and experts": Without independent verification of the the role of remuneration in securing endorsements for AG1, this claim should be treated with a great deal of caution. It's likely the the endorsements made are in return for direct fees or to earn commissions on sales generated.

Single-Arm Study Claims:

AG1 also highlights results from a single-arm study where 97% of participants reportedly felt more sustained energy, and 97% noticed fewer cravings. While these results are superficially encouraging, the study's design—a single-arm without a placebo control—limits the ability to conclusively attribute these effects to AG1 alone (18). The group used was also extremely small with just 35 participants, meaning that it's unlikely to be statistically robust and could have been re-run until the desired result was generated.

User Reviews

User Feedback on AG1

Feedback from users of AG1 often emphasizes the supplement's broad nutritional spectrum, which conveniently packages a variety of vitamins, minerals, probiotics, and adaptogens into one daily scoop. Users frequently report experiencing enhanced energy, improved digestive health, and an overall boost in well-being after adding AG1 to their daily regimen. Regarding taste—a highly subjective measure—AG1 is typically described as favorable or at least more appealing compared to other greens powders, attributed to its use of natural flavorings.

Despite these positives, some users raise issues concerning AG1’s formulation, particularly its reliance on proprietary blends (or variations on this - specifically concerns around not really knowing what they're putting in their bodies, how beneficial it is, or how well it can be expected to work). The use of a proprietary blend intentionally practice conceals the precise quantity of each ingredients in order to make it difficult to gauge the exact nutritional impact of AG1 or to make informed comparisons with competing products.

The high cost of AG1 is frequently cited as a concern, with some users questioning whether the benefits provided justify the expense. This aspect is particularly challenging for those trying to manage their health supplements within a strict budget as AG1 is priced very high when compared to other greens products.

Our Experience With AG1

After a comprehensive 18-month review up to October 18, 2024, we've analyzed AG1's claims of supporting health areas such as cognitive sharpness and immune resilience. Here's a detailed summary of our experiences and findings based on consistent usage.

Nutritional Composition and Wellness Impact

  • Balanced Intake: AG1 features a mix of 75 nutrients, aimed at offering a comprehensive dietary boost. Our observations indicated some minor improvements in general health, possibly linked to the blend of vitamins and minerals included. However, given the absence of clear dosage information, it's hard to pinpoint whether these changes are directly due to AG1 or simply coincidental.

  • Energy and Alertness: The product markets itself as an energy and focus enhancer. A few testers noted slight increases in morning energy levels, which might be linked to B vitamins and iron—nutrients associated with metabolism (19,20). However, these results might also reflect a placebo effect associated with adopting a new supplement regimen. Cognitive benefits were minimal, potentially due to insufficient concentrations of nootropics like Rhodiola, which tend to require higher doses (21).

  • Gut Health: Incorporating probiotics and fiber, AG1 claims digestive benefits. Feedback from testers remained neutral, with no clear improvement in digestion or symptoms like bloating.

Taste Perception

  • Flavor: The taste profile of AG1 includes natural flavorings and stevia, an alternative to synthetic sweeteners. Opinions were divided; some found the sweetness acceptable, while others felt the stevia was too overpowering, describing the flavor as overly sugary. This might suggest the intensity of the stevia is used to mask the natural tastes of other ingredients, and its dominance could be off-putting.

Transparency Concerns

  • Ingredient Disclosure: A major issue with AG1 is the use of a proprietary blend that obscures exact ingredient dosages. This lack of transparency makes it hard to evaluate the supplement's true effectiveness. Despite some positive experiences regarding energy levels and digestion, the uncertainty surrounding actual ingredient quantities diminishes the credibility of the outcomes.

Cost Effectiveness

Our evaluation partially aligns with AG1's marketed benefits. While some energy boosts were noticed, digestive and cognitive effects were less apparent. The strong stevia flavor and the absence of transparent ingredient information were drawbacks. Considering these modest benefits alongside the high cost, we concluded that AG1 may not deliver enough value. Other greens powders we’ve assessed provide clearer, more impactful results at a better price point.

Scientific Evidence for AG1 Ingredients and Health Benefits

Athletic Greens AG1 claims to deliver a vast array of health benefits through a formulation that includes a multitude of vitamins, minerals, and botanical extracts. Each serving is said to enhance mental performance, energy, immune defense, and cardiovascular health. This section critically examines the scientific backing for these claims based on the ingredients used and the dosages that are typically required for efficacy.

Vitamin and Mineral Efficacy

Vitamins A, C, E, and B-Complex: AG1 includes significant percentages of daily values for these vitamins. Vitamin C, known for its immune support, requires dosages around 200 mg per day to impact immune function, a level that AG1 meets and exceeds (22). Vitamin E, which acts as an antioxidant, is also adequately dosed to contribute to cellular protection from oxidative stress (23). However, for B vitamins, which support energy and cognitive functions, the efficacy heavily depends on individual deficiencies and daily requirements, which might not be fully addressed by AG1’s provided doses (24).

Minerals like Zinc and Selenium: These are critical for various enzymatic and immune functions. AG1 claims to include 150% and 36% of daily values, respectively. Zinc supports immune health and is effective in doses around 10-20 mg, which AG1 appears to cover (25). Selenium’s antioxidant properties are typically observed with 55-200 mcg daily, aligning with AG1’s formulation (26).

Botanical Extracts and Probiotics

Adaptogens such as Ashwagandha and Rhodiola: These are used for their stress-reducing properties. Clinical studies suggest effective dosages of Ashwagandha range from 300-500 mg daily (27), and Rhodiola should be consumed at 200-600 mg daily for cognitive and physical fatigue reduction (28). AG1’s proprietary blend likely falls short of these levels due to the sheer number of ingredients sharing the modest 12g serving size.

Probiotics: AG1 includes strains like Lactobacillus acidophilus and Bifidobacterium bifidum, known for digestive health benefits. Effective probiotic supplementation generally requires billions of CFUs; AG1’s content of 3.6 billion CFUs per strain might just meet this threshold, though efficacy can vary based on storage conditions and formulation stability (29).

Issues with Proprietary Blends and Underdosing

A major issue with AG1 is its use of proprietary blends, which obscures the exact amount of most ingredients, making it difficult to validate many of the health claims. This practice not only prevents consumers from understanding what they are ingesting but also typically signifies that many ingredients are underdosed. Given the extensive list of 75 ingredients, it is nearly impossible to include therapeutic doses of each within a 12g serving (30).

The presence of many ingredients in trace amounts is more a marketing feature than a health benefit, as synergistic effects of such low-dosed ingredients are minimal and not supported by rigorous scientific evidence (31).

AG1 contains ingredients that have been individually proven to support health in various ways, the lack of transparency regarding exact dosages complicates the assessment of its overall efficacy. For consumers seeking clear health benefits, the potential underdosing and the use of a proprietary blend are significant issues. It is crucial for a product like AG1, which promises extensive benefits, to provide more detailed information to support its claims convincingly.

AG1 Side Effects

Athletic Greens AG1 is formulated with a diverse array of ingredients intended to support overall health. But even natural ingredients can cause side effects, particularly when not dosed appropriately. Here we explore potential side effects based on the ingredients listed in AG1, considering typical dosages used in clinical studies versus what's present in AG1.

Vitamins and Mineral Overload

  1. Fat-Soluble Vitamins (A, E, K2): AG1 includes vitamins like A and E, which are fat-soluble and can accumulate in the body, leading to toxicity if consumed in excess. Symptoms might include headache, dizziness, or blurred vision from Vitamin A overload (32), and fatigue or muscle weakness from high doses of Vitamin E (33). The presence of Vitamin K2 also requires careful consideration as it can interact with blood-thinning medications (34).
  2. Water-Soluble Vitamins (C, B-Vitamins): While generally safe, excessive intake of water-soluble vitamins like Vitamin C and certain B vitamins can cause gastrointestinal distress such as diarrhea or nausea, particularly at high doses (e.g., Vitamin C doses over 2000 mg) (35).

Minerals

  1. Trace Minerals (Zinc, Copper, Selenium, Chromium): Overconsumption of minerals like zinc can lead to copper deficiency, gastrointestinal symptoms, and immune dysfunction (36). Selenium and chromium, when taken in high doses, may cause toxic effects including liver and kidney problems (37,38).

Botanical Extracts and Adaptogens

  1. Adaptogens (Ashwagandha, Rhodiola): Although beneficial for stress and fatigue, adaptogens like Ashwagandha and Rhodiola can cause mild to moderate side effects such as headache, dizziness, or digestive upset in sensitive individuals or when taken in high doses (39).
  2. Herbal Extracts (Licorice, Ginseng): Licorice root extract can cause hypertension, edema, and hormonal imbalances when consumed excessively. Similarly, ginseng might lead to insomnia, headaches, and possible allergic reactions (40).

Digestive Health Ingredients

  1. Probiotics and Fibers: While generally considered safe, some individuals might experience bloating, gas, or discomfort, especially when first introducing probiotics or significantly increasing fiber intake (41).

Issues with Proprietary Blends and Dosage Transparency

A significant concern with AG1 is the use of proprietary blends, which obscure the exact amounts of each ingredient. This lack of transparency prevents users from knowing whether they are consuming potentially harmful levels of any vitamins, minerals, or extracts. It also complicates the assessment of side effects, as the interaction between numerous ingredients at unknown doses can increase the risk of adverse reactions.

Given the vast number of ingredients and the potential for underdosing or overdosing in a proprietary blend, users should be cautious and monitor for any unexpected symptoms that may arise from daily consumption of AG1. It’s also advisable for individuals with specific health conditions or those on medication to consult healthcare professionals before using AG1.

Athletic Greens Review

Conclusion

After a comprehensive 18-month evaluation period, ending on October 18, 2024, we have reviewed our experience with Athletic Greens AG1. The product includes 75 ingredients aimed at promoting various health benefits, such as mental sharpness and immune function. However, the reliance on a proprietary blend that conceals the exact dosages of these ingredients prevents a full understanding of its effectiveness. In our view, this lack of transparency affects both consumer trust and the perceived efficacy of the product, raising substantial concerns. The limited observed outcomes, coupled with its high cost, further bring into question the product's value for money.

AG1 aims to create a pleasant taste experience by using stevia instead of artificial sweeteners. However, many testers found the flavor too sweet, which detracted from the overall appeal, suggesting that the stevia's strength may overpower other flavors.

In comparison, our evaluation of Supergreen Tonik, our current top-rated greens supplement, showed a markedly different outcome. It provides clear information on the dosages of all its ingredients, which aligns with clinical evidence supporting their benefits. This transparency allowed us to fully understand what we were consuming and the reasons behind it.

During our test period with Supergreen Tonik, we noticed marked improvements in various areas, such as digestive function, mental performance, sleep quality, and an overall sense of well-being—outcomes that were not as evident with AG1. The formula, containing potent superfoods along with nootropic and immune-support blends, offers a more comprehensive and effective approach to health supplementation. We particularly appreciated that each ingredient is present at a level intended to have a meaningful and beneficial impact.
