Collagen supplements come in several forms, and the best choice depends on what you want to support — skin, hair, nails, joints or overall vitality. While all collagen peptides share core benefits, their supporting ingredients differ.
Here’s how to choose a formula that aligns with your needs.
For Skin, Hair and Nails
Look for a collagen formula that includes:
- Vitamin C (supports collagen synthesis)
- Hyaluronic acid (moisture retention)
- Biotin (hair support)
These combinations are ideal if your focus is radiance, elasticity or supporting fuller, stronger hair.
Vitamin C contributes to normal collagen formation.

For Joint Comfort and Movement
A joint-specific collagen formula may include:
- MSM
- Glucosamine
- Chondroitin
These ingredients are commonly used to support joint comfort. According to NHS guidance and information from Versus Arthritis, evidence for glucosamine and chondroitin is mixed and they are not routinely recommended as medical treatments for arthritis.

Marine vs Bovine Collagen
Marine collagen is sourced from fish and tends to have smaller peptide sizes, which some people prefer. Bovine collagen offers a broader range of peptide types. Both have supporting research — the choice is mostly personal preference.

Daily Dose Matters
Most studies showing benefits use 5–10 g of collagen peptides per day. Products with significantly lower doses may not align with the evidence base.

Choose a Format You Can Take Consistently
Whether marine or bovine, powdered or liquid, the best collagen is the one you can take every day. For many, a liquid supplement with a pleasant natural flavour is easier to stick to.
