This site states two figures worth checking against each other: 30 capsules per bottle, and 1 capsule per day.
Unlike some domains in this category where advertised day-supply figures don't match the stated serving size, this site's 30-capsules-to-30-days math is consistent and checkable — 30 capsules divided by 1 capsule daily equals exactly 30 days.
Worth crediting this straightforward, verifiable math as a small but genuine transparency point, particularly relevant if you've also researched other domains in this product category where similar day-supply math doesn't hold up.
