Is AG1 worth it? We checked the label

Vitamin C eases colds at the 420 mg AG1 dose

Grade D

The best data here is a meta-analysis of 10 randomized, double-blind trials. Vitamin C cut cold severity by 15 percent versus placebo, but every included trial used at least 1 gram a day. Not close. One scoop has 420 milligrams, well under half the minimum those trials used. Vitamin C itself has decent evidence, but at this dose AG1's version gets a D.

B12 boosts focus and mood in people who aren't deficient

Grade D

A meta-analysis pooled 16 randomized trials with 6276 people who weren't deficient. It found no effect of B12, alone or with folic acid and B6, on any area of cognitive function, and no overall effect on depression. Only one trial measured fatigue, so the reviewers couldn't analyze it. If your B12 is normal, the 22 micrograms in a scoop is unlikely to change how sharp you feel, so this claim gets a D.

The magnesium in AG1 improves sleep

Grade D

That 200 is the weight of the whole compound. The actual magnesium is 26 milligrams per scoop, though glycinate is an organic form, and a review found organic forms absorb better than inorganic ones. A review of 9 studies and 7,582 adults found observational links with sleep, but the randomized trials contradicted each other. A separate review said three trials weren't enough to judge cognition, so at 26 milligrams this gets a D.

The superfood complex is 7388 milligrams, more than half of the 12 gram scoop. It holds spirulina, chlorella, wheat grass, beet, cocoa, green tea, licorice and more, and every one is marked amount undisclosed. Because you can't compare a hidden dose to a studied dose. Spread across that many plants, most amounts will be small, and none of our sources test this blend, so it gets an F.
