AG1 vs Bloom Greens & Superfoods: What the Labels Say

AG1 vs Bloom Greens at a Glance

Doses above are from the current U.S. Drug Facts or prescribing labels listed in Sources. Always follow the label on the package you buy, because store brands and formulations differ.

Two Different Kinds of Product

Although both are sold as greens powders, the labels describe different products. AG1 lists defined amounts of more than 20 vitamins and minerals per scoop, much like a multivitamin, plus four proprietary blends. Bloom Greens & Superfoods lists seven proprietary blends and only iron and sodium as nutrients with stated amounts. Its scoop is less than half the weight of AG1’s and lists 15 calories versus 50. If you are looking to cover vitamin and mineral needs, AG1’s label tells you exactly what you get. If you want a lighter powder with fiber and plant ingredients, Bloom’s panel shows that, but not how much of each individual ingredient it contains.

What “Proprietary Blend” Means

FDA rules (21 CFR 101.36) let supplement makers list a proprietary blend by its total weight and its ingredients in descending order by weight, without disclosing the amount of each ingredient. That means you can see that Bloom’s greens blend weighs 1,367 mg or that AG1’s superfood complex weighs 7,388 mg, but not how much of any single herb, mushroom, enzyme or probiotic is inside. For ingredients studied at specific doses, such as adaptogens or probiotic strains, this makes it hard to compare a blend with research amounts.

AG1’s Nutrient Amounts in Context

Several AG1 amounts are well above typical daily needs. Its 420 mg of vitamin C, 83 mg of vitamin E, 22 mcg of B12 and 330 mcg of biotin exceed adult Recommended Dietary Allowances or Adequate Intakes. The NIH Office of Dietary Supplements notes that people who take multivitamin-mineral products and other supplements and also consume fortified foods and beverages might get some nutrients in amounts above the upper limit. If you also take a multivitamin, check overlapping nutrients such as vitamin A, zinc and folic acid.

Testing Claims

The AG1 label states NSF Certified for Sport, a program that tests for banned substances in sport and checks label claims; you can search certified products on NSF’s site. The Bloom label states third party tested without naming the program. Supplements are not approved by FDA for safety or effectiveness before sale.

Putting It Together: Common Situations

The scenarios below summarize what the labels and guidelines cited on this page say. They are general information, not a personal treatment plan. Your pharmacist can check the choice against your other medicines, and your clinician can tailor it to your health history.

• Want defined vitamin and mineral amounts: AG1’s label lists them; Bloom’s mostly does not.
• Want fewer calories and a smaller scoop: Bloom lists 15 calories in 5.64 g.
• Competitive athlete: look for a named certification such as NSF Certified for Sport on the exact product.

How to Read the Label Before You Buy

1. Find the active ingredient first. Brand names are often reused across products with different ingredients. The active ingredient and its strength appear at the top of the Drug Facts or Supplement Facts panel.
2. Check the “Uses” or labeled indication. A product is tested and labeled for specific uses. Using it for something else may not help.
3. Read the “Do not use” and “Ask a doctor before use” sections. They list conditions and medicines where the product may be unsafe.
4. Follow the directions for dose and duration. Note the maximum daily amount and how many days you can use it before checking with a clinician.
5. Check for duplicate ingredients. Combination products can contain the same ingredient as something else you take, which raises the risk of taking too much.
6. Note the “Stop use and ask a doctor” signs. These are the label’s own warning signs that a product is not working or is causing harm.

Common Mistakes to Avoid

• Stacking a greens powder on a multivitamin without checking overlap.
• Expecting a blend to match research doses when individual amounts are not disclosed.
• Assuming two products with similar names are interchangeable. Compare the active ingredients and strengths instead of the packaging.
• Forgetting to tell your clinician. Keep a current list of every prescription, OTC medicine and supplement you take, and bring it to appointments and the pharmacy.

How to Read a Greens Powder Label

Start with the serving size and calories, then the list of nutrients with amounts and percent Daily Value. Next, look at any proprietary blends: their total weight, and the order of ingredients, which reflects descending weight. Check the other ingredients for sweeteners and allergens, and the statements for third-party certification and warnings. Compare products per serving, since scoop sizes differ more than twofold between these two.

Food First

Greens powders can add some nutrients and fiber, but they do not provide the volume of fiber, water and varied plant compounds in whole fruits, vegetables, beans and whole grains. If cost or convenience is a concern, frozen vegetables, a basic multivitamin when needed, and a fiber supplement are alternatives to discuss with a clinician or dietitian.

How Much of Each Scoop Is Blends

Adding up the blend weights on each label shows how the scoops are built. Bloom’s seven blends total about 4,993 mg of its 5,640 mg serving, so nearly the whole scoop is blended ingredients whose individual amounts are not listed. AG1’s four blends total about 10,328 mg of its 12 g serving, with the vitamins and minerals listed separately with amounts. The largest Bloom blend is fiber (1,606 mg), roughly 1.6 grams, which is a small share of the 22 to 34 grams of daily fiber NIDDK suggests for adults. AG1’s probiotic blend weighs 54 mg, and neither label lists colony-forming units for individual strains in the database record we reviewed. If a specific ingredient matters to you, contact the company and ask for the amount per serving and the testing behind it. Product formulas also change over time, so compare against the label on the package you buy.

When to Talk to Your Doctor or Pharmacist

Ask a clinician or pharmacist before using greens powders if you are pregnant or breastfeeding, take prescription medicines or other supplements, or have kidney disease. Children should not use adult supplement powders unless a clinician advises it.
