Quick answer: AG1 is worth it only if convenience matters more to you than control. It’s a well-tested, NSF Certified for Sport drink with named probiotic strains. But when we read the full AG1 Next Gen label, 42 of its ingredients sat inside two blends with no individual amounts, it has no vitamin D, and it gives just 7% of your daily magnesium. Most people can cover the same bases with a basic multivitamin, a probiotic and real vegetables.
AG1 (formerly Athletic Greens) is one of the most-searched supplements in the US, promoted with “75+ ingredients” in one scoop. Instead of judging the taste, we went line by line through the official AG1 Next Gen supplement facts, compared the amounts with NIH recommendations, and checked what the company says about testing and research. We read labels and sources. We don’t run a lab, and we didn’t test AG1 ourselves.
What We Found When We Read the Whole Label
One scoop of AG1 Next Gen weighs 13 grams. Here’s how that scoop breaks down, according to AG1’s own supplement facts, checked on October 25, 2026:
| Part of the scoop | Amount | Do you know how much of each ingredient? |
|---|---|---|
| Vitamins, minerals and other listed nutrients | 30 items | Yes, each has an amount |
| Active Superfood and Prebiotic Complex | 7.5 g (21 ingredients) | No, only the blend total |
| Daily Phytonutrient Complex | 1.5 g (21 ingredients) | No, only the blend total |
| Probiotic blend | 10 billion cells (5 strains) | Strains named, but not the count of each |
That means 9 of the 13 grams, about 69% of the scoop, are in blends where you can’t see how much of any single ingredient you’re getting. That matters for ingredients like ashwagandha, which is inside the 7.5-gram blend. In our ashwagandha review, the NIH notes studies used 240 to 1,250 mg a day of extract. With 21 ingredients sharing that blend, there’s no way to know whether AG1 comes close.
What AG1 Gets Right
- Third-party certification. AG1 says it is NSF Certified for Sport, that every batch is screened for over 280 banned substances, and that it tests every batch for lead, mercury, cadmium and arsenic.
- Named probiotic strains. The label lists exact strains, like Lactobacillus rhamnosus GG and Bifidobacterium lactis HN019. In our probiotic strain check, most best-sellers didn’t do that.
- Low sugar and easy to take. 40 calories, under 1 gram of sugar and 2 grams of fiber per scoop. If you hate pills, one drink a day is simple.
What’s Missing, and What’s Way Too High
| Nutrient | Per scoop | % Daily Value | What it means |
|---|---|---|---|
| Vitamin D | Not listed | 0% | AG1 sells vitamin D3+K2 drops separately |
| Magnesium | 30 mg | 7% | Far below the 250 mg used in a recent sleep study |
| Calcium | 120 mg | 9% | Most still has to come from food |
| Iron | 1 mg | 6% | Little help if you need iron |
| Vitamin B12 | 400 mcg | 16,667% | Very high, but the NIH says B12 hasn’t been shown to cause harm |
| Biotin | 330 mcg | 1,100% | Can skew some lab tests |
| Vitamin C | 500 mg | 556% | High, but below the 2,000 mg upper limit |
| Zinc | 20 mg | 182% | Half the 40 mg adult upper limit on its own |
Two of these deserve a warning. The NIH says biotin supplements above recommended amounts may cause false results in some lab tests, including thyroid hormone tests, so tell your doctor you take AG1 before blood work. And the NIH sets the upper limit for zinc at 40 mg a day for adults. AG1 gives 20 mg, so adding a multivitamin or a zinc supplement on top can push you close to it.
The low magnesium surprised us most, because the NIH says the diets of many people in the US provide less magnesium than recommended. If that’s why you want a daily supplement, our magnesium for sleep guide covers the doses that were actually studied. And for vitamin D, see our vitamin D dose check.
Does AG1 Work? What the Research Shows
AG1 lists several clinical trials of its Next Gen formula on its website. They’re mostly small and short: from 16 people over 8 hours to 105 adults over 12 weeks, plus one 3-month study of how 104 people felt, with no placebo group. The controlled trials compared AG1 with a placebo, not with a regular multivitamin. So they can show AG1 does something compared with nothing, but not that it beats a cheaper routine.
That’s the key question for most buyers. AG1 is mainly a multivitamin, a probiotic and a greens blend in one drink. Each of those parts can be bought separately, with amounts you can see on the label.
Who Should Buy AG1, and Who Shouldn’t
| AG1 may suit you if | Skip AG1 if |
|---|---|
| You won’t take pills but will drink one glass a day | You want vitamin D, magnesium or calcium in meaningful amounts |
| You’re an athlete who needs NSF Certified for Sport products | You want to know exactly how much of each herb you’re taking |
| Convenience is worth a higher price to you | You already take a multivitamin or zinc (zinc adds up) |
| You eat few vegetables and want a simple habit | You’re pregnant, take medication or have a health condition, unless your doctor agrees |
AG1 is sold mainly as a monthly subscription on its own site, and an AG1 Store bundle with a storage canister is also listed online: check the current price of the AG1 bundle. Prices and offers change often, so compare the cost per serving with the alternatives below.
Cheaper AG1 Alternatives
There’s no exact copy of AG1, but you can rebuild what it does, often with clearer labels. Start with what you actually need:
1. The “Build Your Own AG1” Routine
A basic multivitamin covers the vitamins and minerals, a probiotic with named strains covers gut support, and a greens powder or simply more vegetables covers the rest. You see every amount, and you can add the nutrients AG1 skips, like vitamin D. Our guides to the best multivitamin for women, the best probiotic for women and the best vitamin D supplement show which products state their doses clearly.
2. Best Budget Greens Powder: Amazing Grass Super Greens
If you mainly want the greens part, this is the most-reviewed option we found, with a 4.5-star average from over 50,000 ratings. It’s certified organic and has no added sugar. Keep in mind it’s a greens and superfood blend, not a full multivitamin. Check the current price of Amazing Grass Super Greens
3. Best Greens + Probiotic: Orgain Organic Greens
Orgain combines 50 organic superfoods with 1 billion probiotics and 7 grams of fiber per serving. That’s fewer probiotics than AG1’s 10 billion, but it gives you more fiber. It has a 4.4-star average from over 16,000 ratings. Check the current price of Orgain Organic Greens
4. Best Organic Juiced Greens: Garden of Life Perfect Food
Garden of Life uses over 40 greens, sprouts, fruits and vegetables, including concentrated grass juices. It’s USDA Organic, NSF Certified Gluten Free and stevia-free, which helps if you dislike stevia (AG1 uses it). It has a 4.4-star average. Check the current price of Garden of Life Perfect Food
AG1 Side Effects
Most people tolerate greens drinks well, though the fiber and probiotics can cause gas or bloating at first. Watch for three things: biotin can skew lab tests, zinc adds up if you take other supplements, and the herbal blend includes ingredients like ashwagandha and licorice root that may not suit everyone, especially if you’re pregnant or take medication. AG1’s label also lists soy as an allergen.
The PrimeDigger Verdict
- Is AG1 worth it? For most people, no. You pay for convenience, and 69% of the scoop is in blends you can’t measure.
- Where it shines: NSF certification, named probiotic strains and a simple one-drink habit.
- The smarter route for most: a basic multivitamin, vitamin D if you need it, a strain-named probiotic, and more vegetables, or a budget greens powder if you want the drink habit.
