3/5
Moderate
evidence
Micronutrient evidence brief
Calcium
Supports bone health when intake is low or risk is high, but it is not a strength, hypertrophy, or acute performance supplement.
Headline Finding
Mineral-performance review: calcium is bone-health relevant, not a reliable direct performance supplement.
Dose Context
Use diet-first intake review and pair with vitamin D status where relevant; avoid excessive supplemental calcium.
Important Caveat
Casual calcium use is not appropriate for every lifter; audience targeting and baseline intake matter.

How To Read This Rating
The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
