Recovery evidence brief
HICA and KIC are leucine-related metabolites marketed for soreness, anti-catabolic effects, and lean-mass support. They appear in some recovery and muscle-preservation products.
HICA and KIC are sold as anti-catabolic leucine metabolites, but human sport evidence is sparse, small, and not strong enough for muscle-gain marketing.
Small HICA/KIC trials exist; evidence is too sparse for anti-catabolic or muscle-gain claims.
HICA and KIC are distinct compounds. HMB, leucine, and GAKIC claims do not automatically apply to plain HICA/KIC products.
Body-composition or recovery benefits need independent athlete trials with product-matched dosing.

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.
Send the disputed claim, source link, and why it changes the practical verdict. Corrections that materially affect the claim, dose, caveat, or rating are prioritized.
