What it is & primary uses
A trace element marketed for glucose metabolism despite uncertainty about essentiality and broad benefits.
Main benefits
- May address deficiency in specialized clinical contexts.
- Weight-loss and glucose benefits in the general population are small or inconsistent.
Studied protocols
Research doses are grouped by outcome. They describe study designs—not a personal prescription.
25–35 mcg/day adequate intake for adults
- Study duration
- Daily; deficiency treatment may require clinician-directed dosing and monitoring
- Interpretation
- Strong for nutritional adequacy; not evidence that high-dose supplementation improves outcomes in already-replete people.
04Food sources & equivalents＋
Can food provide a studied amount?
Meat, whole grains, some vegetables and grape juice can provide related dietary exposure, but food and extract milligrams are not automatically interchangeable.
Dietary exposure; verify composition before comparing with a studied supplement dose
- How this was estimated
- Dose Radar compares the declared active ingredient with official composition data or the studied standardized extract—not with marketing names.
- Important limitation
- Natural content, preparation, bioavailability and formulation vary. This comparison does not prove equal physiological effect.
Food equivalents compare ingredient mass using published composition values. They do not prove equal absorption, formulation, physiological effect, safety or personal need.

With food
Food commonly improves gastrointestinal tolerance, although it can change absorption for some ingredients.
- Practical approach
- With food. Keep the formulation and daily total consistent with the evidence context shown above.
- Watch for
- Insulin and glucose-lowering medicines
Meal guidance reflects human pharmacokinetic, clinical, official-label or evidence-review sources where available. A food pairing can change absorption or tolerability, but does not make a supplement necessary, effective or safe for every person.
Source: NIH ODS Chromium fact sheet ↗06Supplement interaction check＋
An unlisted pair means no established pair-specific interaction was identified in this review—not proof that every dose, product or person is safe.
This is not proof that every dose, product or user context is safe. Medication and condition checks still apply.
07Research notes＋
Strong evidence for the stated context. Strong for nutritional adequacy; not evidence that high-dose supplementation improves outcomes in already-replete people.
The strongest use is meeting a physiological requirement or correcting documented inadequacy. More than needed does not create a proportional benefit.

Dose context: Ingredient-specific human literature; dose and formulation vary
This live index supports source verification. A new paper does not change the Dose Radar grade until its design, population and formulation are reviewed.
09Expert & media references＋
Podcast and practitioner statements are clearly separated from research. They may explain practice or emerging ideas, but do not prove efficacy.
