AG1 (Athletic Greens) Review: Is It Worth the Hype?

AG1 by Athletic Greens is arguably the most recognized and heavily marketed greens powder on the market. With endorsements from podcasters, athletes, and wellness influencers, it has built a reputation as a premium all-in-one nutritional supplement. But does the product justify the price and the hype? We spent several weeks testing AG1 and dug into the ingredients, research, and value proposition to give you an honest assessment.

What Is AG1?

AG1 is a powdered nutritional supplement that combines 75 vitamins, minerals, whole-food-sourced nutrients, probiotics, and adaptogens into a single daily scoop. Athletic Greens positions it as a foundational nutrition product designed to fill gaps in your diet, support energy, immunity, gut health, and overall well-being.

Each serving (one scoop mixed with water) provides a blend organized into four categories: vitamins and minerals, superfoods and antioxidants, adaptogens and functional mushrooms, and probiotics and digestive enzymes.

Ingredient Breakdown

Vitamins and Minerals

AG1 provides meaningful doses of several key micronutrients, including 100% or more of the daily value for vitamins C, E, B1, B2, B6, B12, biotin, and folate (as methylfolate, the bioavailable form). Zinc is present at 15 mg, and chromium at 200 mcg. Vitamin D is included but at a relatively modest amount, which means you may still need a separate vitamin D supplement depending on your levels.

Superfoods and Antioxidant Complex

This proprietary blend includes spirulina, wheat grass juice powder, apple powder, cherry powder, bilberry extract, broccoli flower powder, and several other plant-derived ingredients. While each of these foods has demonstrated antioxidant properties in isolation, it is difficult to evaluate their effectiveness within a proprietary blend because the individual amounts are not disclosed.

Adaptogens and Functional Mushrooms

AG1 includes ashwagandha root extract, rhodiola rosea, reishi mushroom, and shiitake mushroom. Research on adaptogens suggests they may help the body manage stress responses, though most clinical studies use higher doses than what is typically found in multi-ingredient blends. Without knowing the exact amounts of each adaptogen in AG1, it is challenging to compare directly to clinical study doses.

Probiotics and Digestive Enzymes

The formula includes 7.2 billion CFU of probiotics from two strains: Lactobacillus acidophilus and Bifidobacterium bifidum. This is a moderate probiotic dose. Digestive enzymes including bromelain and protease are also included, which some people report help with nutrient absorption.

Our Testing Experience

Taste and Mixability

AG1 has a mildly sweet, earthy flavor with a noticeable greens taste that is not unpleasant. We found it mixes best in cold water, where the flavor is refreshing. In warm water, the taste becomes more pronounced and less appealing. Using a shaker bottle produces a smoother texture than stirring with a spoon. Some people add AG1 to smoothies, but this dilutes the flavor to the point where it is barely noticeable.

Energy and How We Felt

After two weeks of daily use, the most consistent observation was a mild but noticeable increase in sustained energy throughout the day, without the jitteriness associated with caffeine. Digestive regularity also improved slightly, which could be attributed to the probiotic and enzyme components. These are subjective observations, and individual experiences will vary.

Convenience Factor

The single-scoop simplicity is genuinely appealing. Rather than managing a cabinet full of individual supplements, AG1 consolidates a broad range of nutrients into one daily habit. For people who are inconsistent with taking multiple pills, this convenience factor may be the most practical benefit.

What We Like

• Comprehensive nutrient profile — 75 ingredients covering multiple nutritional categories
• Bioavailable vitamin forms — Methylfolate, methylcobalamin (B12), and chelated minerals
• Third-party tested — NSF Certified for Sport, which provides meaningful quality assurance
• No artificial sweeteners, colors, or preservatives
• Taste is genuinely decent for a greens powder, better than many competitors
• Travel-friendly single-serving packs are available for purchase

What Could Be Better

• Proprietary blends hide individual ingredient amounts — This is our biggest concern. While the total blend weights are listed, you cannot see how much spirulina, ashwagandha, or any individual ingredient is in each serving. This makes it impossible to compare to clinical study doses.
• Price is high — At roughly $3 to $4 per serving with a subscription, AG1 is one of the most expensive greens powders available. A monthly subscription runs approximately $79 to $99 depending on the plan.
• Vitamin D is underdosed — Many people need 2,000 to 5,000 IU of vitamin D daily, and AG1 does not provide enough on its own.
• Subscription model can feel pushy — While one-time purchases are available, the entire experience is optimized around committing to a monthly subscription.
• Not a replacement for a healthy diet — Despite the marketing, AG1 works best as a supplement to an already nutritious diet, not as a substitute for eating well.

How AG1 Compares to Alternatives

Feature	AG1	Bloom Greens	Garden of Life Raw Organic
Ingredients	75	30+	34
Probiotics	7.2B CFU	1B CFU	No
Third-Party Tested	NSF for Sport	No	USDA Organic
Price per Serving	~$3-4	~$1.50	~$2
Taste	Good	Very Good	Earthy
Proprietary Blends	Yes	Yes	No

AG1 offers the most comprehensive ingredient list and strongest third-party certification, but Garden of Life provides full transparency on ingredient amounts, and Bloom offers a more affordable entry point.

Who Is AG1 Best For?

AG1 may be a good fit for people who want a convenient, all-in-one daily supplement rather than managing multiple individual products, those who travel frequently and want a portable nutrition option, individuals with busy lifestyles who struggle to eat a consistently nutrient-rich diet, and people willing to pay a premium for quality and convenience.

AG1 may not be the best choice for budget-conscious consumers, those who want full transparency on individual ingredient doses, people with specific nutrient needs that require targeted supplementation, or anyone who prefers to get their nutrition primarily from whole foods.

Final Thoughts

AG1 is a genuinely well-formulated greens powder with strong third-party testing and a pleasant taste. The convenience of a single daily scoop covering a wide nutritional spectrum is its greatest selling point. However, the proprietary blends, premium pricing, and modest vitamin D content are legitimate drawbacks. If the budget works for you and you value convenience, AG1 is a solid choice. If transparency and value are more important, alternatives like Garden of Life or building your own targeted supplement stack may serve you better.
