Supplement stacking checker
Add the products you take together. We add up each ingredient’s daily amount from the labels and compare the total with the Daily Value (DV) and the Tolerable Upper Intake Level (UL).
Use the search box above to add 2–6 products.
Totals add up label figures only; they are not lab-tested, do not adjust for different forms or absorption, and leave out food and water. DV and UL are general adult references, not personal advice. If you are pregnant, breastfeeding, take medicines or have a chronic condition, ask a doctor or pharmacist first.
For information only; not medical advice. Talk to a doctor or pharmacist before starting or stopping any supplement.
