A supplement pack’s price is easier to compare when you know what the pack contains. Check the number of bottles, the quantity in each bottle and the serving size on the label. Then divide the total price by the number of labeled servings. Compare the same formula and serving size first; a lower cost per serving does not tell you which supplement is suitable for you.
Start with the same product
A one-bottle and three-bottle option may look like a straightforward comparison. First, confirm that both contain the same product, formula, bottle size and labeled serving size. Similar names and bottle designs are not enough.
Write down these details for each option:
- The full product name and form, such as capsules or liquid.
- The bottle count in the pack.
- The quantity in each bottle, such as 60 capsules.
- The serving size and servings per container shown on the label.
- The price for the whole pack.
- Any shipping charge, taxes or discounts shown at checkout.
If the package quantity and product description disagree, ask the seller to clarify before placing an order. Keep a copy of the listing and order confirmation so you can compare them with what arrives.
Separate capsules from servings
A capsule is a unit in the bottle. A serving is the quantity used to express the ingredient amounts on the Supplement Facts panel. They can be different: a bottle with 60 capsules and a serving size of two capsules contains 30 labeled servings. Read our Supplement Facts label guide for help locating these fields. FDA describes serving-size and servings-per-container information in its dietary supplement labeling guide.
For a pack of identical bottles:
Total labeled servings = bottles in the pack × labeled servings per bottle.
If the servings-per-container line is absent, do not invent a serving size. Check the actual quantity and serving information or ask for a clear label. FDA permits omission of the servings-per-container line when it repeats the net quantity information.
Calculate cost per labeled serving
Cost per labeled serving = total price ÷ total labeled servings.
The table below uses invented prices and quantities to show the arithmetic. It is not a Valdivia offer, a dosing recommendation or a statement about any actual product.
| Hypothetical option | Bottles | Capsules per bottle | Capsules per labeled serving | Total labeled servings | Product price | Product cost per serving |
|---|---|---|---|---|---|---|
| Pack A | 1 | 60 | 2 | 30 | $18.00 | $0.60 |
| Pack B | 3 | 60 | 2 | 90 | $45.00 | $0.50 |
Pack A contains 60 ÷ 2 = 30 servings. Pack B contains 3 × 30 = 90 servings. Pack B has a lower product cost per serving in this example, but requires a larger payment at checkout.
To compare the final amount you would pay, repeat the calculation using the total after applicable discounts, shipping and taxes. Use the same approach for each option. Avoid comparing one seller’s discounted price with another seller’s price before a discount you qualify for.
Do not turn servings into days without the directions
Thirty labeled servings does not automatically mean a 30-day supply. Read how much the label directs you to take and how often. The Supplement Facts serving size and the full directions answer different questions.
For a simple quantity estimate, divide the total capsules by the number of capsules taken per day under the label directions. If directions permit a range, the result is also a range. A fixed supply claim should account for the maximum labeled daily amount. Never change how much you take to make a pack last longer or to improve its apparent value.
Check whether a larger pack fits your order
Lower unit cost is only one part of the decision. Before ordering several bottles, check the posted return conditions, storage instructions and any date information available for the actual stock. Ask customer support if you need information that is missing from the page.
Our shipping policy and return policy explain Valdivia’s current terms. Read the policy itself before ordering, particularly the conditions for opened and unopened bottles.
Buying more does not demonstrate that a product will work, that a larger serving is better, or that it is appropriate for you. FDA recommends discussing a supplement with a doctor, pharmacist or other healthcare professional before using it. See FDA’s consumer information on dietary supplements.
A quick check before checkout
Confirm that you are comparing the same formula and serving size. Check bottle count, total servings and the final checkout price. Read the directions, storage information and return conditions. If a label or pack description is unclear, contact the seller for clarification.
You can use this method when comparing currently available Valdivia listings. Use the actual label and checkout total for each order; the numbers above are examples only.
