AG1 tries to replace your multivitamin, greens powder, probiotic, and adaptogen stack in a single scoop. The vitamins are the strongest part — you're getting 420mg **Vitamin C**, 83mg **Vitamin E** in its natural form, and **Folate** as bioactive 5-MTHF at 680mcg, all at clinically relevant doses. **Zinc** at 15mg covers your daily needs, and the 7.2 billion CFU **Probiotic** blend with named strains adds genuine gut support.

The tradeoff for cramming this much into one product is transparency. Two proprietary blends — 7,388mg of superfoods and 2,732mg of herbs — hide individual doses for **Ashwagandha**, **Rhodiola**, **CoQ10**, **Vitamin K2**, and over a dozen other ingredients. The 154mg mushroom complex splits across five ingredients including **Reishi**, which alone needs 1,000mg+ in clinical studies. With that many compounds sharing the space, most are likely well below their studied doses.

At roughly $99/month, you're paying a premium for convenience — and the vitamins and probiotics justify part of that. But **Magnesium** at just 26mg (6% of a clinical dose) is a notable gap for a product positioning itself as comprehensive, and the headline adaptogens and superfoods are impossible to verify at their hidden doses.

Natural FlavorsFlavor

Broad regulatory category of flavor constituents derived from natural sources. Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.

How to Take It

Take it anytime

No evidence a formula this broad works better at any particular hour. Take it with a meal containing fat — the vitamins A and E in it absorb poorly without one.

With a meal containing fat
Keep it away from hot food or drink
Space it a couple of hours from Iron and Calcium

On the label

Suggested use: Mix one scoop of AG1 with 8oz of cold water. Shake. Enjoy the refreshing taste of pineapple and vanilla.
