AG1 (Athletic Greens)

What Is AG1 (Athletic Greens)?

AG1, formerly known as Athletic Greens, is a comprehensive greens powder that combines 75 vitamins, minerals, probiotics, adaptogens, and whole-food-sourced ingredients into a single daily serving. Founded by Chris Ashenden in 2010, AG1 has become one of the most recognized supplements in the wellness space, driven largely by high-profile podcast sponsorships from hosts like Andrew Huberman, Joe Rogan, and Tim Ferriss.

At $79 per month on a subscription basis, AG1 positions itself as a nutritional insurance policy—a convenient way to cover potential gaps in your diet without managing a dozen individual supplement bottles. It is NSF Certified for Sport, meaning it has been independently tested for banned substances and label accuracy, a meaningful distinction in an industry where third-party verification remains optional. Single-serve travel packs are also available for those who frequently travel and want to maintain their routine on the road.

How It Works

AG1 delivers its 75 ingredients across several functional categories: vitamins and minerals, prebiotics and probiotics (7.2 billion CFU of Lactobacillus acidophilus), adaptogens (ashwagandha, rhodiola), digestive enzymes, and superfood extracts (spirulina, chlorella, wheatgrass). Each serving is mixed with cold water and consumed once daily, ideally in the morning on an empty stomach per the brand's recommendation.

The formula uses proprietary blends, which means that while the total weight of each blend category is listed, the exact dosage of most individual ingredients is not disclosed. This is the central tension with AG1: you know what is in it, but for many components, you cannot confirm whether the dose reaches a therapeutically meaningful level. For example, ashwagandha research typically uses 300–600mg daily, but AG1 does not disclose how much ashwagandha its adaptogen blend contains. Similarly, the spirulina and chlorella content may be well below the amounts used in studies that demonstrated potential benefits.

AG1 may support general nutrient intake and digestive comfort, though individual responses vary widely depending on baseline diet quality and nutritional status. The brand cites internal research and customer surveys, but independent clinical trials specifically evaluating AG1 as a complete product have not been published in peer-reviewed journals.

Key Features

• 75-ingredient formula: Spans vitamins, minerals, probiotics, adaptogens, and whole-food extracts in a single scoop
• NSF Certified for Sport: Independent verification for banned substance screening and label accuracy
• 7.2 billion CFU probiotics: Lactobacillus acidophilus strain, though lower than many dedicated probiotic supplements which often provide 10–50 billion CFU
• Single-serve travel packs: Individually wrapped sachets for convenience on the go
• No proprietary blend dosage disclosure: Total blend weights are listed, but individual ingredient amounts within blends are not fully transparent

Our Testing Experience

Mixing AG1 is simple—one scoop in cold water produces a mildly sweet, grassy-tasting drink that most of our team found palatable but not enjoyable. The taste is noticeably better when mixed with coconut water or blended into a smoothie. Some testers found that adding a squeeze of lemon also helped mask the earthy undertone. Digestive comfort was the most consistently reported observation: several testers noted reduced bloating within the first two weeks, which may be attributable to the probiotic and enzyme components.

Energy claims were harder to evaluate objectively. Some testers reported feeling more alert in the mornings, though this could reflect placebo response, improved hydration from the morning ritual, or genuine micronutrient repletion. The lack of individual ingredient dosing makes it difficult to attribute specific effects to specific compounds. We also noted that the morning ritual itself—mixing and drinking a green beverage first thing—may create a positive psychological anchor that influences perceived energy levels independent of the supplement's pharmacological effects.

The $79/month price point is significant when compared to targeted alternatives. A high-quality multivitamin like Thorne Basic Nutrients ($42/month) paired with a standalone probiotic ($15–25/month) may deliver more transparent dosing at a similar or lower total cost. However, AG1's convenience factor—one scoop replacing multiple bottles—is genuinely appealing for users who value simplicity over precision. It is also worth noting that AG1 offers a 90-day money-back guarantee, which reduces the risk of trying the product.

The Bottom Line

AG1 is a convenient, well-marketed greens powder that may help fill nutritional gaps for people with inconsistent diets. The NSF Certified for Sport designation adds meaningful credibility, and the probiotic component may support digestive comfort for some users. However, the proprietary blend structure limits transparency, and the $79/month cost is a premium price for a product where individual ingredient dosing cannot be independently verified. Users who prefer full dosage transparency and targeted supplementation may find better value in products like Thorne Basic Nutrients paired with individual supplements chosen for their specific needs. For those who prioritize convenience above all else and want a single daily ritual that covers broad nutritional ground, AG1 remains the most recognized option in the greens powder category.
