Serving Size Math: Why Bottle Counts Can Mislead
Two bottles can both hold 60 capsules and still last completely different amounts of time — and cost completely different amounts per day. The capsule count on the front of the bottle isn't the number that actually matters.
Capsule count vs. servings per container
A "60 capsule" bottle sounds like a fixed quantity, and it is — but how long it lasts depends entirely on the serving size, which varies by product. If the label says "Serving Size: 1 Capsule," a 60-capsule bottle is a 60-day supply. If it says "Serving Size: 2 Capsules," that identical 60-capsule bottle is only a 30-day supply. Same bottle size, same capsule count, half the duration.
The math that actually matters: cost per day
To compare two products fairly, divide total price by the number of days the bottle actually lasts at its stated serving size — not by the capsule count, and not by the sticker price alone. A $40 bottle that's a 60-day supply costs about $0.67/day. A $30 bottle that's a 30-day supply — which sounds cheaper up front — actually costs $1.00/day. The lower price tag doesn't win once you account for how long it lasts.
Multi-bottle bundles complicate this further
Bundle pricing (buy 3, buy 6, and similar) often lowers the per-bottle price, but the relevant comparison is still cost per day, not cost per bottle — and it's worth checking whether shipping is bundled into that lower per-bottle price or added separately, since that changes the real total. Read the fine print on what "free shipping" tier actually requires (a specific bundle size, a minimum order) rather than assuming it applies across the board.
Where to find the numbers you need
Everything required for this math — serving size, servings per container, and price per package tier — is required to be on the label and is legally required to be accurate. Our product pages show the Supplement Facts panel exactly as labeled and each package tier's actual price, so the cost-per-day math is always something you can do yourself directly from what's published, not something you have to take our word for.
