Per-Bottle Value Math for Supplement Shoppers

Why bottle price alone misleads

Two bottles on a shelf can carry the same sticker price and cover very different stretches of time. One might hold 30 capsules, another 60, another 90. If you compare only the number on the tag, you are comparing nothing in particular. The honest comparison is cost per day, and it takes about ten seconds to work out.

This article gives you a repeatable method. We will use the Visivra™ pack figures as the worked example because they are clean: every bottle holds 30 capsules, which is a 30-day supply taken as directed on the bottle label.

Think of this as a small piece of shopping literacy. Once you have the habit of converting prices into daily figures, grocery aisles and online listings start to look different, and flashy front-of-pack claims matter far less than the numbers on the back.

The three-step formula

You need only three numbers: the price of the bottle, the number of servings in it, and the number of servings you take per day.

• Step 1: Divide the number of capsules in the bottle by the capsules you take daily. That gives you days per bottle.
• Step 2: Divide the bottle price by days per bottle. That is your cost per day.
• Step 3: Multiply by 30 if you want a monthly figure for your budget.

Keep the label open while you do this. Our walkthrough on reading a supplement label step by step shows where serving size and servings per container are printed, which are the two inputs people most often skip.

The worked example

Using the brand's stated pricing, here is what the math produces for each pack:

• 2 bottles at $79 each: $79 divided by 30 days is about $2.63 per day. The pack covers 60 days.
• 3 bottles at $69 each: $69 divided by 30 is $2.30 per day. The pack covers 90 days and ships free in the US.
• 6 bottles at $49 each: $49 divided by 30 is about $1.63 per day. The pack covers 180 days and also ships free in the US.

Notice how the daily figure shifts as the pack grows. The difference between the smallest and largest pack is roughly one dollar per day, which is the kind of gap that only becomes visible once you do the division. You can see the packs described in full on the how it works and ordering page.

You can also express the gap in monthly terms. A month at the two-bottle rate is $79. A month at the three-bottle rate is $69. A month at the six-bottle rate is $49. Same 30 capsules, same directions on the label, different monthly figure, and the only thing that changed is the size of the pack you chose at the start.

Add shipping and the full period

A fair comparison includes shipping. Free US shipping applies to the three and six bottle packs, so for those the price on the page is the price you pay. For smaller orders from any seller, add shipping to the total before you divide.

Then look at the whole period, not only the daily slice. The six-bottle pack totals $294 for 180 days. The three-bottle pack totals $207 for 90 days. The two-bottle pack totals $158 for 60 days. A bigger total feels heavier at checkout, but you are buying a longer stretch, so always line up the totals against the days they cover.

A useful habit is to keep a tiny spreadsheet or a page in a notebook with three columns: product, price per day, and days covered. Add a row each time you shop and you will have a personal price book that makes every future decision faster and calmer.

Value is more than a number

The cheapest day-rate is not automatically the best choice. Value also includes whether you will actually keep up the habit, whether you have room to store extra bottles, and whether the return terms give you breathing room. The brand states a 60-day money-back guarantee, which lowers the stakes of trying a pack and is worth weighing alongside the arithmetic.

If you are still deciding on size, our pack sizes guide describes who each option tends to suit. And if you want to keep a larger supply orderly, the piece on reorder reminders shows how to schedule the next order before you need it.

Use the method on everything

The beauty of cost per day is that it travels. Apply it to any product with a serving count, from pantry staples to other supplements, and the comparison becomes fair instantly. Write the result next to the price on a sticky label if you like, so the number is there the next time you shop.
