How to Work Out Supplement Cost Per Day and Per Serving
Supplement cost per day is the pack price divided by the number of days it lasts. Days come from servings: capsules in the bottle divided by capsules per day. A Reviralis bottle holds 60 capsules, 30 servings at two a day, so $79, $69 and $49 a bottle work out to $2.63, $2.30 and $1.63 a day.

The formula01
How do you calculate supplement cost per day?
Divide the price of the bottle by the days it lasts. Days are the capsules in the bottle divided by the capsules you take a day.
Q: Which number do people get wrong? A: The capsules per day. A pack may say one while the label says two. Always use the label's serving size.
Find days per bottle
Capsules in the bottle divided by capsules per day.
Divide the price
Price per bottle divided by days per bottle gives the cost per day.
Compare per serving
Cost per serving is the price divided by servings. It matches cost per day when you take one serving daily.
Worked example02
What is the Reviralis cost per day?
It depends on the pack: $2.63, $2.30 or $1.63 a day at two capsules a day. The label sets a serving at two capsules, so a 60-capsule bottle is 30 servings.
The sales page lists the three packs and their prices (Reviralis sales page). We print only those figures.
| Pack | Price | Per bottle | Days covered | Per day |
|---|---|---|---|---|
| 2 bottles | $158 | $79 | 60 | $2.63 |
| 3 bottles | $207 | $69 | 90 | $2.30 |
| 6 bottles | $294 | $49 | 180 | $1.63 |
The 2-bottle pack carries a small shipping fee at checkout, and the amount is not printed. Shipping is free on the 3 and 6 packs.
Bigger packs03
When is a bigger supplement pack worth it?
A bigger pack is worth it only when you are sure you will use it. A lower daily cost saves nothing on bottles you never finish.
Ask three questions before you buy: Have you tried the product? Do your clinician and pharmacist know about it? Do you understand the return terms? The guarantee runs 60 days, with return shipping paid by the buyer, and the guarantee page explains the steps.
The pricing page has a planner for mixing packs. For a longer look at how long a bottle lasts, read how long a bottle lasts.

What can cost per day not tell you?
It tells you price per capsule, not value. It cannot say how much of any ingredient is in a dose.
The Reviralis label prints 22 vitamin and mineral amounts but only a 661 mg total for its 18-name blend, so the blend splits cannot be priced. See the proprietary blend page for what the order of names allows.
Cost per day also says nothing about results. Reviralis is not an antiviral, and no source we found shows that it prevents or reduces outbreaks. A prescribed medicine is the proven care for herpes (CDC, About Genital Herpes), and that cost sits outside this math.
Fair comparison05
How do you compare cost per day across two supplements?
Compare the same unit: price per day at the label's serving. Then compare what each label prints.
- Use the label serving, not the pack's wording.
- Count shipping and any return costs in the total.
- Check how many named ingredients have printed amounts.
- Ignore struck-through prices and bonus values; only the price you pay counts.
FAQ06
Reviralis questions people ask
What is cost per serving for a supplement?
Cost per serving is the bottle price divided by the servings in it. A Reviralis bottle has 30 servings of two capsules, so the per-serving figure matches the daily figure when you take one serving a day.
Why does the capsules-per-day number matter so much?
It sets the days per bottle, which sets the cost per day. Using one capsule instead of two doubles the days and halves the cost on paper. Use the label's serving size, which for Reviralis is two capsules.
Is the 6-bottle pack the cheapest per day?
On the sales page, yes: $1.63 a day, against $2.63 for two bottles and $2.30 for three at two capsules a day. It only saves money if you will use 180 days of capsules.
Should shipping count in cost per day?
Yes. Add any shipping fee to the pack price before you divide. The Reviralis 2-bottle pack has a small fee at checkout, amount not printed, while the 3 and 6 packs ship free in the US.
Can cost per day tell me which supplement is better?
No. It compares price only. It does not show how much of each ingredient you get, how well it is made or whether it helps. Read the label and ask a pharmacist about your medicines.
