Best Supplements for Skin Health

Omega-3 has the most support for skin, with astaxanthin, collagen and vitamin C behind it. Collagen is the category's most-marketed supplement, and it doesn't lead. Here's what each one does.

Skin health works from the inside out. These supplements have the most support for skin elasticity, collagen synthesis and protection from aging.

The Skin Health Stack

Supplements for skin from the inside out:

  • Collagen peptides - 5-15g daily for skin elasticity (15g is the dose on record)
  • Vitamin C - essential cofactor for collagen synthesis; pair with collagen
  • Omega-3 - reduces inflammation that accelerates collagen breakdown
  • Astaxanthin - crosses the blood-retinal and blood-brain barriers; potent antioxidant

Common Mistakes

  1. Taking collagen without vitamin C. The body cannot form proper collagen fibers without adequate vitamin C.
  2. Using collagen as a protein replacement. It's low in leucine, which makes it a poor protein.
  3. Ignoring sun protection. UV damage is the primary cause of skin aging.
  4. Expecting quick results. Skin collagen turnover takes 8-12 weeks to show visible improvements.
