AG1 review: is Athletic Greens actually worth $79/month in 2026?
AG1 (formerly Athletic Greens) is the most marketed supplement on the internet. Huberman, Attia, Rogan, and half of YouTube's fitness creators are paid to promote it. At $79/month subscription ($99 one-time), it promises to replace your multivitamin, greens powder, probiotic, and adaptogen stack in one scoop. We put it through our 6 proposition value scoring system and compared it head-to-head against building your own Foundation Stack. Here's the honest verdict.
AG1 Next Gen is a convenient, well-manufactured, NSF Certified for Sport greens powder with 75+ ingredients. However, it uses proprietary blends that hide individual doses, contains vitamins in amounts that often far exceed the RDA (meaning you'll excrete the excess), and costs $79/month — nearly the same as building a targeted Foundation Stack ($74/month) that addresses your specific needs with clinically effective doses of each ingredient. For most people, the Foundation Stack is a better investment. AG1 is best suited for athletes with high nutrient demands, frequent travelers who can't maintain a supplement routine, or people who simply won't take multiple pills and need one-scoop convenience.
What is AG1 Next Gen?
AG1 Next Gen (spring 2026 reformulation) is a powdered daily supplement containing 75+ vitamins, minerals, probiotics, prebiotics, digestive enzymes, adaptogens, and superfood extracts. You mix one 13g scoop into 8oz cold water and drink it, ideally on an empty stomach before breakfast. It's NSF Certified for Sport, manufactured in New Zealand under GMP standards, and backed by a 90-day money-back guarantee.
The Next Gen formula added 5 new probiotic strains (now 10 billion CFUs total), expanded the vitamin/mineral profile, and improved the taste with subtle vanilla sweetness. Solubility has improved significantly.

AG1 vs. the Foundation Stack: head-to-head cost comparison
This is the comparison AG1's marketing doesn't want you to see. Let's stack $79/month of AG1 against $74/month of our Foundation Stack:
| Nutrient | AG1 Next Gen | Foundation Stack | Winner |
|---|---|---|---|
| Magnesium | ~60mg (form undisclosed, likely oxide) | 300mg glycinate (Transparent Labs) | Foundation |
| Vitamin D3 | 50mcg (2,000 IU) | 62.5mcg (2,500 IU) + K2 100mcg | Foundation (has K2) |
| Omega-3 | Not included | 1,280mg EPA+DHA (Nordic Naturals) | Foundation |
| Creatine | Not included | 5g monohydrate (Thorne) | Foundation |
| Probiotics | 10 billion CFU (5 strains) | Not included (add ~$15/mo) | AG1 |
| Greens/superfoods | 7g+ superfood blend | Not included | AG1 |
| Adaptogens | Ashwagandha, rhodiola (doses unknown) | Not included (add via Mood Stack) | AG1 (convenience) |
| B vitamins | 100-1,000%+ of DV (excess) | Multivitamin covers 100% DV | Tie (AG1 over-doses) |
| Cost | $79/month | $74/month | Foundation |
| Convenience | 1 scoop | 5-6 pills/capsules | AG1 |
The takeaway: The Foundation Stack provides clinically effective doses of the 4 most important supplements (magnesium, D3+K2, omega-3, creatine) — none of which AG1 includes at meaningful levels or at all. AG1 wins on probiotics, greens, and convenience. If you value convenience above targeted efficacy, AG1 makes sense. If you want to actually move the needle on specific health outcomes, the Foundation Stack is the better $74-79/month investment.
Who AG1 is actually good for
Athletes in tested sports: The NSF Certified for Sport testing is genuinely valuable. If you're a professional or collegiate athlete who needs certified supplements, AG1 is one of the safest all-in-one options.
Frequent travelers: The travel packs are convenient. Carrying 5 individual supplement bottles while traveling is a pain. One AG1 packet per day solves this.
People who won't take pills: If the alternative to AG1 is taking nothing at all, then AG1 is absolutely better than nothing. One scoop covers basic vitamin/mineral needs plus probiotics.
Everyone else: Build the Foundation Stack instead. You'll get clinically effective doses of the supplements that actually matter most, for the same price or less.
Bottom line
AG1 is a well-made, safe, convenient product that's marketed brilliantly and priced aggressively. At $79/month, it's not a scam — but it's not optimal either. The proprietary blends prevent you from knowing whether individual ingredients are at effective doses. It misses the two most impactful supplements entirely (omega-3 and creatine). And the excess water-soluble vitamins are, as one dietitian bluntly put it, "expensive urine." For most Health Britannica readers, the Foundation Stack at $74/month delivers more targeted, evidence-backed supplementation. But if convenience is your #1 priority, AG1 with its 90-day money-back guarantee is a low-risk way to establish a daily supplement habit.
