Collagen is the most abundant protein in the human body, acting as the "glue" that holds our skin, bones, muscles, tendons, and ligaments together. As we age, natural collagen production declines, leading to wrinkles, joint stiffness, and weaker hair and nails.

Not all collagen is created equal. Use this checklist to evaluate any product before purchase.
Always choose hydrolyzed collagen peptides. This means the collagen has been broken down into smaller peptides (low molecular weight) that your body can absorb efficiently. Non-hydrolyzed gelatin (from cooking) is less bioavailable.
Look for seals from NSF International, USP, or Informed Sport. These verify purity, potency, and absence of contaminants like heavy metals, pesticides, or banned substances. Grass-fed and pasture-raised certifications (like PCO Certified) ensure ethical sourcing.
Most studies use 10-20g per day. Start with 10g and increase if needed. Powder forms are most versatile (mix into coffee, smoothies, soup). Capsules are convenient but typically provide only 1-2g per serving, requiring many pills to reach an effective dose.
To get the most out of your supplement:
Collagen is generally safe, but some people experience mild bloating or a feeling of fullness. Those with fish, egg, or bovine allergies should check labels carefully. Pregnant or nursing women should consult a doctor before starting any new supplement.
