What is BioPerine?
BioPerine® is a branded black pepper extract included in the capsule formula. An added ingredient changes the formula; it is not a reason to assume the capsules are universally better than the tablets.
60 vs 180 BioPerine capsules
At the labeled two-capsule serving, the 60-count bottle contains 30 servings and the 180-count bottle contains 90 servings. How many days a bottle lasts depends on the applicable label directions and professional advice.
Compare the tablet label separately
Do not assume one tablet equals one capsule. Check elemental magnesium per serving, units per serving and other ingredients on each current package.
How to compare cost
Divide the selected bottle price by labeled servings. For the BioPerine capsule options, use 30 or 90 servings respectively. Use the tablet label’s own serving count for the tablet calculation.
Which format should I choose?
Consider your preferred format, the full ingredient list and serving size. If you take medicines, ask a pharmacist to review the complete formula, including added black pepper extract, before use.
