What is AG1? The Foundational Nutrition Drink
AG1, formerly known as Athletic Greens, is a popular all-in-one greens powder supplement that contains over 75 ingredients, including vitamins, minerals, probiotics, superfoods, and adaptogens. Marketed as a foundational nutrition habit, one scoop mixed with water is designed to replace multiple supplements like a multivitamin, probiotic, and greens powder. The product is formulated to support various aspects of health, including gut health, immune function, energy levels, and mood balance. However, as with any supplement, its real-world efficacy and value for money require a closer look beyond the marketing. A key selling point for AG1 is its third-party testing by organizations like NSF Certified for Sport, which verifies the product is free of banned substances and harmful contaminants.
Analyzing the Ingredients and Claims
AG1's formula is comprehensive, but most of its plant-based and herbal ingredients are included in proprietary blends. This means the specific amounts of each individual component are not disclosed, making it difficult to determine if they are present in clinically effective doses.
The Probiotic and Prebiotic Blend
AG1 contains 10 billion CFUs of five dairy-free probiotic strains (like Lactobacillus acidophilus and Bifidobacterium bifidum) and prebiotic fiber from ingredients like inulin. Company-funded clinical trials have shown a positive impact on the gut microbiome, with increased levels of beneficial bacteria and potential improvements in self-reported digestive comfort. However, some users report initial digestive upset, such as bloating or diarrhea, as their body adjusts.
Vitamins and Minerals
The powder delivers high doses of many essential vitamins and minerals, often exceeding the Recommended Daily Value (DV) by hundreds or even thousands of percent. While this may fill nutrient gaps for individuals with poor diets, much of this content comes from synthetic, rather than naturally derived, sources. AG1 also notably lacks iron and sufficient vitamin D, meaning users may need additional supplements for these crucial nutrients.
Superfoods and Adaptogens
AG1 includes numerous superfoods (e.g., spirulina, chlorella) and adaptogens (e.g., ashwagandha, rhodiola) intended to support immunity, stress management, and energy. While these ingredients have individual research supporting their potential benefits, the small, undisclosed quantities in AG1's proprietary blends raise questions about their actual effectiveness.
The Verdict: AG1's Pros and Cons
Like most nutritional supplements, the usefulness of AG1 is not clear-cut and depends on individual circumstances. While many customer testimonials report increased energy and better digestion, experts remain cautious, emphasizing that it should supplement, not replace, a balanced diet.
Pros:
- Convenience: A single daily drink replaces the need for several different supplements, which is ideal for a busy lifestyle.
- High Nutrient Content: Provides robust doses of many key vitamins and minerals, potentially helping to fill nutritional gaps.
- Gut Health Support: The combination of probiotics and prebiotics is clinically shown (in company-funded trials) to foster a healthy gut microbiome.
- Third-Party Certification: Being NSF Certified for Sport assures users of product purity and safety from banned substances.
Cons:
- High Cost: At around $3 per serving, AG1 is one of the most expensive greens powders on the market.
- Proprietary Blends: The lack of transparent ingredient amounts makes it impossible to verify the efficacy of most superfood and adaptogen doses.
- Missing Nutrients: Crucial vitamins and minerals like D and iron are either absent or present in very low amounts.
- Not a Whole Food Substitute: AG1 contains only 2g of fiber per scoop and lacks the full spectrum of benefits found in eating whole fruits and vegetables.
- Limited Independent Evidence: Few independent, peer-reviewed studies exist to support the majority of AG1's health claims. For more on supplement skepticism, you can read the McGill Office for Science and Society's take.
AG1 vs. Other Greens Powders: A Comparison
To understand AG1's position in the market, a comparison with other popular alternatives is helpful. AG1 stands out for its extensive ingredient list and third-party testing, but competitors often offer more transparency or a lower price point.

|---|---|---|---|
| Cost per Serving | ~$2.63 - $3.30 | ~$1.33 | ~$1.53 |
| Ingredients | 75+ ingredients in proprietary blends | 20+ ingredients, some proprietary | Fewer ingredients, emphasizes prebiotics |
| Transparency | High for vitamins/minerals, low for blends | Moderate, some blends lack detail | High transparency, full doses listed |
| Probiotics (CFU) | 10 Billion | 5 Billion | N/A (focus on prebiotics) |
| Certifications | NSF Certified for Sport | GMP-certified, third-party tested | Informed Choice certified |

Is AG1 Right for You?
Choosing a supplement depends on your health goals, budget, and dietary habits. AG1 might be a good fit if:
- You have nutrient deficiencies that are difficult to address through diet alone.
- You prefer the convenience of an all-in-one supplement over multiple pills.
- You are an athlete who benefits from the NSF Certified for Sport assurance of quality.
- You have a high budget and prioritize a wide variety of added nutrients and compounds.
Conversely, AG1 may not be the best choice if:
- You already maintain a healthy, balanced diet rich in fruits and vegetables.
- Your budget is tight, as more affordable alternatives exist.
- You require specific doses of ingredients, as AG1's proprietary blends don't offer that transparency.
- You are pregnant, breastfeeding, or have certain health conditions; you should consult a doctor first.
Conclusion: The Bottom Line on AG1's Usefulness
So, is AG1 actually useful? The answer is nuanced. It is a high-quality, comprehensive supplement that delivers a significant dose of vitamins and minerals, along with probiotics shown to support gut health. For individuals with specific nutrient gaps or dietary restrictions, or those seeking the convenience of a single daily drink, it can be a valuable addition. The premium ingredients and rigorous third-party testing justify its high price for some.
However, for the average person with a healthy diet, the cost is a major consideration, especially given the lack of specific dosages for many ingredients in its proprietary blends. AG1 is not a replacement for eating whole foods, and its claimed benefits beyond nutrient gap-filling are not yet independently substantiated. Ultimately, a balanced, whole-food diet remains the cornerstone of good health, and AG1 serves best as a supplement to that foundation—not a substitute.
Before starting any new supplement, it is always recommended to consult with a healthcare professional to ensure it aligns with your specific health needs and goals.
