Quick Answer
Start with the serving size, then check which B vitamins are listed, the amount of each and the %DV. Watch three numbers against their upper limits: niacin (35mg), B6 (100mg) and folic acid (1,000mcg, which is about 1,667mcg DFE)[1][2][3]. Then look at forms, sugar and whether the product is third-party tested.

Step 1: Check the serving size
All amounts on the panel are per serving, not per gummy or pill. A serving of 3 gummies means you need three to get the listed amounts. Also check servings per container to compare cost per day.
Step 2: Understand the units
- mg (milligram) is 1,000 times bigger than mcg (microgram).
- Niacin, B6, pantothenic acid and vitamin C are listed in mg. B12, biotin and folate are listed in mcg.
- Folate is listed as mcg DFE, which accounts for folic acid being absorbed better than food folate[3]. See Folate vs. Folic Acid.
Step 3: Read the %DV
%DV compares the amount to a daily reference value for adults. Over 100% isn't automatically a problem. For example, B12 is often listed well above 100% because only a small fraction of a large oral dose is absorbed: about 2% at 500mcg[4].
Step 4: Check the upper limits
Add up every product you take, including a multivitamin.
Step 5: Look at the forms
- Niacinamide doesn't cause flushing. Nicotinic acid can[1].
- B6 is usually pyridoxine HCl. B12 is often cyanocobalamin or methylcobalamin.
- Check "Other Ingredients" for sugar, gelatin (not vegan) and allergens.
Example: our B Complex label
Serving size 1 gummy, 60 per bottle. Vitamin C 10mg (11% DV), niacin 12mg as niacinamide (75%), B6 1.2mg (71%), folate 430mcg DFE (108%), B12 20mcg (833%), biotin 50mcg (167%), pantothenic acid 6mg (120%), inositol 3.5mg (no DV). 10 calories and 2g added sugar.

Frequently asked questions
What does the dagger (†) mean on a label?
It means no Daily Value has been set for that ingredient, as with inositol.
Why is B12 833% DV?
Because only a small share of oral B12 is absorbed at higher doses, and B12 has no upper limit[4].
Are supplements approved by the FDA?
No. The FDA doesn't approve supplements before sale, which is why independent testing matters[5].
