Why Take Collagen and How Does It Work?
Collagen is the most abundant protein in the human body. It ensures the cohesion, elasticity, and regeneration of all connective tissues: skin, tendons, ligaments, and cartilage. Starting at age 25, our natural production declines, leading to wrinkles and joint discomfort. Supplementing with hydrolyzed collagen (peptides) sends a signal to the body to restart its own production — visibly improving skin hydration and joint comfort.
Our Criteria for Selecting the Best Collagen
- Origin and Purity: We prioritize marine collagen (from wild-caught fish or sustainable aquaculture) for its biological similarity to human collagen, or pasture-raised bovine collagen for its complete profile. We systematically verify the absence of hormones, antibiotics, and heavy metals through independent lab certificates.
- Molecular Weight (Daltons): To be effective, collagen must be consumed as hydrolyzed peptides, not whole (gelatin). We select products with low molecular weight (below 2,000–4,000 Daltons) for maximum bioavailability and optimal intestinal absorption.
- Collagen Types (I, II, III): Depending on your goals, type matters. Type I is ideal for skin beauty and hair, while Type II specifically targets cartilage. Our comparisons help you pinpoint the right product for the right need.
What Results to Expect from a Course?
Clinical studies show that a 1–3 month course (at 10g per day) can redensify the dermis, smooth fine lines, and reduce pain linked to osteoarthritis or athletic strain. It's the ultimate anti-aging and recovery supplement.
