When Should You Start Taking Collagen? A Complete Guide
Collagen is a protein that helps support your skin, bones, joints, and other tissues.
Your body slowly makes less collagen starting in your mid-20s.
This does not mean everyone must begin taking collagen supplements at that age.
In your 20s, healthy food, enough protein, vitamin C, sleep, water, and sun protection may be the main priorities.
Some people may consider supplements in their 30s when they notice changes in their skin.
People in their 40s and beyond may also consider them as part of a healthy lifestyle.
Marine collagen usually comes from fish skin or scales and mainly contains type I collagen.
Supplements should add to healthy habits rather than replace them.
Natural collagen production begins to decline from the mid-20s, but there is no mandatory age to start supplements.
People in their 20s are generally advised to prioritize protein, vitamin C, sun protection, hydration, sleep, and other healthy habits.
Collagen supplements may be considered in the 30s as changes in skin firmness, hydration, or texture appear.
In the 40s and beyond, supplements may provide additional support alongside a healthy diet and exercise.
Hydrolyzed peptides, ingredient sources, dosage, additives, and manufacturing practices are key factors when choosing a supplement.
