What is the recommended dose of collagen for hair growth?

There is no official recommended dose of collagen specifically for hair growth. Collagen supplements are marketed for general hair, skin, and nail support, but clinical evidence for improving hair growth is limited.

Most collagen supplements provide around 2.5 to 10 grams of hydrolysed collagen peptides per day, depending on the product and manufacturer instructions. These doses are commonly used in studies investigating collagen for skin or joint health.

Key points:

• There is no established recommended dose of collagen for hair growth.
• Typical supplement doses range from 2.5 to 10 grams of hydrolysed collagen peptides per day, depending on the product.
• Collagen supplements are marketed for hair, skin, and nail support, but evidence for hair growth benefits is limited.
• It is best to follow the dosing instructions on the product label and consult a healthcare professional if unsure.
