Compare Vitamin Prices Per Serving
How Vitamins pricing is compared on Dealophant
Listings are ranked by price per serving where weight isn't available; where Amazon publishes a per-ounce rate, Dealophant uses that instead because serving sizes can be inflated by manufacturers.
We calculate the price per serving (tablet, capsule, or gummy) across all bottle sizes and brands.
Each listing's total Amazon price is divided by the serving count extracted from the product title and (where available) cross-checked against Amazon's own price.pricePerUnit field. The result is a single live price-per-serving number that's directly comparable across every brand and pack size in the category. The lowest price per serving earns the "Best Value" badge.

Frequently asked questions about vitamins
- What are the cheapest multivitamins per serving on Amazon?
- The cheapest multivitamins per serving are value brands like Kirkland Signature, Nature Made, or Amazon Elements in 300-365 count bottles, often priced at $0.03-$0.06 per serving. Premium brands like Garden of Life or Ritual run $0.30-$1.00+ per serving.
- Are expensive vitamins better than cheap ones?
- Not necessarily. All vitamins sold in the US are subject to FDA regulations. Independent testing by ConsumerLab shows that many budget brands contain the same active ingredients at the same potency as premium brands. The main differences are form (gummy vs tablet), additional ingredients, and marketing.
- Are gummy vitamins worth the extra cost?
- Gummy vitamins cost 2-3x more per serving than tablets but contain the same active ingredients. They may also have added sugar. Choose gummies if you have difficulty swallowing pills, but tablets are the better value.
- What's the cheapest vitamins per serving on Amazon right now?

- How does Dealophant calculate price per serving for vitamins?
- Total listing price is divided by the canonical serving count extracted from the product title. vitamins is typically labeled by serving count, but where weight is available Dealophant ranks by ounces instead, because manufacturers can change serving size to inflate apparent value. Cross-unit listings (for example a serving-count tub mixed in with weight-based tubs) are shown separately under "Other formats" so the price-per-serving ranking stays apples-to-apples.
- Is bulk vitamins actually cheaper per serving?
- Usually yes, but not always — Dealophant has seen single-pack vitamins undercut bulk on a per-serving basis when the smaller size is on sale or has a Subscribe & Save discount the bulk listing doesn't. That's why Dealophant always recomputes per-serving price live rather than assuming bigger = cheaper.

- It varies by brand, format, and current promotions. To see the live range, sort the listings at https://dealophant.com/compare/vitamins by Price Per Unit ascending — the cheapest and most expensive in-stock options are visible immediately. The "Best Value" badge marks the lowest price per serving in the current result set.
