| Cost Per Day | Rating | What it typically means |
|---|---|---|
| Under $0.50 | Excellent | Budget-friendly basics (magnesium, zinc, vitamin D). Good value for foundational supplements. |
| $0.50 – $1.00 | Good | Mid-tier single or simple multi-ingredient formulas. Standard for quality basics. |
| $1.00 – $2.00 | Average | Multi-ingredient formulas, branded extracts. Reasonable for complex products like nootropics or probiotics. |
| $2.00 – $3.50 | High | Premium formulas. Justified only if using patented ingredients at therapeutic doses. |
| Over $3.50 | Very High | Usually overpriced. Check if ingredients justify the cost. |
Many supplements show a low per-bottle price but require 3 capsules per serving. A "90 capsule" bottle is only 30 days. Always calculate from servings per container, not capsule count.
Most supplement brands offer 20-40% discounts for 3-month or 6-month bundles. If you plan to take a supplement for more than 2 months, always check if a bundle is available.
A cheaper supplement is not better value if it uses inferior forms. Magnesium oxide at $0.10/day has 4% bioavailability. Magnesium glycinate at $0.50/day has 80%+ absorption.
A 180-day money-back guarantee significantly changes the value equation. A 30-day guarantee with a $60 bottle is a much higher-risk purchase.
