More category questions
Does collagen actually work or is it just hype?
Yes — multiple randomized controlled trials show oral collagen peptides (10-15g/day) significantly improve skin elasticity (+15-20%), reduce wrinkles, strengthen nails, and reduce joint pain over 8-12 weeks. The key is hydrolyzed peptides (not gelatin) which are small enough to be absorbed and signal fibroblasts to produce new collagen.
When is the best time to take collagen?
Collagen can be taken anytime. Many people add it to morning coffee or smoothies. For joint benefits, some practitioners recommend taking on an empty stomach. For skin, consistency matters more than timing. Take with vitamin C for optimal synthesis.
How much collagen should I take daily?
For skin: 5-10g/day (Verisol studies). For joints: 10-15g/day. For gut healing: 15-20g/day. Most collagen powders provide 10-20g per scoop. Studies consistently show 10g/day as the minimum effective dose for measurable skin improvement.
What is the difference between collagen and gelatin?
Both are collagen protein, but hydrolyzed collagen peptides are broken into smaller fragments (1-6 kDa) that dissolve in cold water and are absorbed more efficiently. Gelatin is partially hydrolyzed — it forms a gel, doesn't dissolve in cold liquids, and has lower bioavailability. For supplementation, always choose hydrolyzed collagen peptides.
