Biotin 10000 mcg Plus Keratin 100 mg
Mason Natural
Overview
This product combines a very high dose of biotin with keratin, claiming to support skin and hair health. Biotin is an essential vitamin, but the excessive dose in this supplement does not seem necessary and may cause problems. While keratin has potential benefits, scientific evidence supporting the combination with biotin and its effectiveness through oral supplementation is limited. Calcium is included, but at a minimal dose that is unlikely to provide significant benefit.
The Good
Gluten free and soy free, accommodating some dietary restrictions.
Contains ingredients generally regarded as safe.
The Bad
High dose of biotin may interfere with lab tests.
Limited evidence for combination of biotin and keratin.
Insufficient evidence for hair and nail benefits.
Is it for you?
Best For: Individuals seeking to improve hair, skin, and nail health; those with brittle nails or thinning hair
Skip If: You are undergoing lab tests (especially thyroid or cardiac markers) or have known allergies to ingredients.
