Collagen Declines 1% Every Year After 25 — Here's What to Do

ByBryan JohnsonBlueprintLongevityNutrition

Hi friend,

Natural collagen production drops by ~1% each year after age 25. UV exposure makes it worse.

Supplementing collagen can support skin structure and the appearance of healthy skin aging.*

We created a broad-spectrum collagen peptide supplement to support skin elasticity. You don't need to buy from us… but if you're considering supplementing collagen, you should know what to look for.

Types of Collagen

Collagen is a protein made from amino acids. It provides structural support in places like your skin, tendons, bones, and ligaments.

There are 28 different types of collagen. Type I makes up over 90% of the collagen in your body. Types II and III are also important:

  • Type I collagen: supports skin, tendons, and bone health
  • Type II collagen: supports cartilage integrity and flexibility
  • Type III collagen: supports skin firmness and is involved in early wound healing

Collagen Health Benefits

You can get collagen from foods like bone broth, chicken skin, and salmon. Plant-based foods don't contain collagen, but they provide nutrients that support collagen production. You can also supplement.

Collagen supports:*

  • #1: Mobility

    • supports joint flexibility and joint health
    • promotes connective tissue strength

  • #2: Recovery

    • promotes muscle recovery
    • helps muscles rebuild after exercise
    • supports muscle comfort

  • #3: Vitality

    • supports energy
    • supports bone strength

  • #4: Hair, skin, and nails

    • promotes skin elasticity
    • supports hair and nail maintenance
    • supports healthy skin aging

What to Look For

Some collagen supplements underdose, failing to achieve study-level support. Many are contaminated with fillers and heavy metals. Others don't contain the types of collagen needed for overall skin, joint, and muscle support.

Look for supplements that are third-party tested and broad spectrum, to get maximum support from your collagen.

Blueprint Collagen Peptides:

  • are broad spectrum with type I, II, and III collagen
  • are third-party tested for purity and heavy metals
  • contain 20g of protein and 0g of sugar
  • are unflavored so you can mix them with anything
