Why take collagen and how does it work?

Collagen is the most abundant protein in the human body. It provides cohesion, elasticity and regeneration for all our connective tissues: skin, tendons, ligaments and cartilage. From around age 25, natural production declines, leading to wrinkles and joint discomfort. Supplementing with hydrolyzed collagen (peptides) sends a signal to the body to boost its own production, visibly improving skin hydration and joint comfort.

Our criteria for selecting the best collagens

  • Origin and purity: We favor marine collagen (from wild-caught fish or sustainable aquaculture) for its biological similarity to human collagen, or grass-fed bovine collagen for its complete profile. We systematically check for the absence of hormones, antibiotics and heavy metals through independent certificates of analysis.
  • Molecular weight (Daltons): To be effective, collagen should not be consumed "whole" (gelatin) but as hydrolyzed peptides. We select products with a low molecular weight (under 2,000 or 4,000 Daltons) to guarantee maximum bioavailability and optimal absorption through the intestinal barrier.
  • Collagen types (I, II, III): Depending on your goals, the type matters. Type I is ideal for skin and hair beauty, while Type II specifically targets cartilage. Our rankings help you match the right product to the right need.

What results can you expect?

Clinical studies show that a 1 to 3 month course (around 10g per day) can help densify the dermis, smooth fine lines and reduce discomfort linked to osteoarthritis or exercise. It is the go-to supplement for healthy aging and recovery.
