When a product needs something, we tell you
A tablet can't hold its shape without a little help. So we name exactly what's in ours, and why.
How we compared: in September 2026 we read the "Other ingredients" line on our 30 current products and on 1,610 products from 10 supplement brands that sell the same actives we do. A product counts as additive-free when it has no added filler, binder, flow agent, sweetener or color. Capsule shells, liposome carriers and preservatives don't count against a product.
