Why do certain supplements cost more than others

Question

Why do certain supplements cost more than others that look like they have similar ingredients?

Answer 1

Just looking at the ingredients does not essentially offer enough information to assess value. For illustration, the similar amount of elemental calcium can be found as, among others, citrate or carbonate, however encompass significantly distinct absorption dynamics. Carbonates are much cheaper, and therefore are often employed by supplement manufacturers, even although the more costly citrates are better absorbed. Often, higher quality comes with a high price.
