Do I need it?
Start with a specific goal, your diet, and any diagnosed deficiency. A supplement can be useful for one situation and offer little benefit in another.

A better decision.
Before another bottle.
Migaku helps you work out whether a supplement makes sense for your goal, what its label means, and which questions to take to a pharmacist or clinician.
Sometimes the useful answer is to compare two products. Sometimes it is to address diet, sleep, or a possible deficiency first. Sometimes it is to save your money.
Build a supplement decisionInformation should change what you do next.
What does the evidence support?
Look for human research on the outcome you care about. A change in a laboratory marker or an animal experiment does not establish a health benefit for you.
What is actually in the serving?
Check the active amount, units, and capsules per serving. The weight of a blend or compound can differ from the amount of the ingredient you want.
What could make it unsuitable?
Consider medicines, other supplements, pregnancy, health conditions, and total intake. Take the label to a pharmacist or clinician when these apply.
Is it worth the cost?
Compare cost per labelled serving, evidence for your goal, and verifiable quality testing. An expensive form or a high rating does not establish better health outcomes.
Our content has limits.
Some legacy content was produced with AI assistance. Not every page has been individually medically reviewed. A publication date, an editorial team label, or a numerical score is not evidence of clinical review.
We do not present this site as a healthcare service, a supplement testing laboratory, or a certification programme. We have not published a reproducible clinical scoring model or verified reviewer credentials for all existing pages. Treat legacy scores and rankings as unverified reference information, never as clinical recommendations.
Ingredient research also cannot establish the purity, contents, or effectiveness of a particular product or batch. Those claims need separate, verifiable evidence.

Some buying pages include affiliate links. A purchase through one of these links may earn Migaku a commission. Keep this commercial relationship in mind when reading a product list.
Before buying, check the current manufacturer label, retailer price, and any certification in the certifier's own directory. We cannot infer product quality from a retailer rating or a brand's marketing language.
Help us correct a claim
A correction is most useful when it includes the page URL, the exact sentence or dose at issue, and a link to the source that supports the correction. If a source has been retracted, updated, or applies to a different population, include that detail.
