7 PRACTICAL GUIDES
Check before buying
Evidence, claims, product identity and the questions worth asking before checkout.
THE COMPARISON DESK
Less guesswork.
Better denominators.
Use the numbers on your label and at checkout. Every default is illustrative. Every formula is explained.
Open all tools
Cost per serving calculator
Turn a bottle price and serving size into a comparable unit cost and supply estimate.
Ingredient unit cost calculator
Compare cost per gram of one explicitly identified ingredient, using the amount per labeled serving.

Keep the label, evidence and checkout questions together. Progress saves only in this browser.
FIELD NOTES
Small details. Real differences.
Four questions worth a closer look.
Read the label
Serving size vs. bottle count: why 120 capsules may mean 60 servings
Distinguish capsule count, labeled servings and days of supply so that package-size comparisons use the same denominator.
Read the label
Fish oil and algal oil: compare the EPA and DHA amounts you mean
Keep total oil, EPA, DHA and serving size separate so that an omega-3 cost comparison answers a clearly defined question.
Do the math
Bulk supplement packages: find the usable-serving break-even point
Compare bulk and small packages using expected usable servings, cash required today and a transparent break-even calculation.
Check before buying
Supplement certification logos: verify the exact product and scope
Look up a supplement certification with the issuing program and keep product identity, program scope and clinical claims separate.
A REFERENCE, NOT A RANKING
Compare what can
actually be compared.
Capsules, powders, oils and blends need different denominators. Start with a useful basis and keep the gaps visible.
Explore the comparison tableWHAT GOES UNDER THE PRICE?
- Capsules
- Labeled servings
- Minerals
- Named mineral amount
- Fish & algal oil
- Quantified EPA + DHA
- Proprietary blends
- Whole serving, with gaps noted
Unit cost measures cost. It does not measure clinical effect.
Frequently asked questions
Do you rank the best supplements?
No. We explain comparison methods and information gaps. We have not purchased, laboratory tested or clinically evaluated products.
Are the example prices real offers?
No. Every price example and tool default is illustrative. Enter the total from your own current checkout.
Does a lower unit cost mean better value?
Only within the narrow comparison you define. It cannot tell you whether an ingredient is needed or two formulations are interchangeable.
Can the tools recommend a dose?
No. Any daily-use input is supplied by you for budgeting. Ask a qualified healthcare professional about personal use.
Where does the information come from?
Guides link to US official resources and separate label observations from original arithmetic. See the source notes in each guide.
Do you sell products or earn affiliate commissions?
This local implementation has no product sales, affiliate links or active ad scripts. Any future commercial integration needs its own disclosures.
