Marine Collagen — Uses, Dosage, Side Effects & Safety

Drug class: Health & Lifestyle Management

Overview

Marine Collagen is a dietary supplement derived from the skin, scales, and bones of fish and other marine sources. It is commonly used to support skin health, joint function, and overall connective tissue strength. Many people take marine collagen to improve skin elasticity, reduce wrinkles, and promote hair and nail growth. Marine collagen works by providing the body with essential amino acids, particularly glycine, proline, and hydroxyproline, which are the building blocks of collagen in the body. Supplementation may help replenish natural collagen levels that decline with age. Key points to know: Marine collagen is generally well-tolerated, but individuals with fish allergies should avoid it. It is not a substitute for a balanced diet or medical treatment for chronic conditions.
