From the Research
Collagen supplements may have a modest effect on improving skin elasticity, hydration, and reducing wrinkles, but more rigorous research is needed to fully understand their effectiveness for aging. Based on the most recent and highest quality study available 1, typical doses of collagen supplements range from 2.5-10 grams daily, taken consistently for at least 8-12 weeks to potentially see effects. Some key points to consider when evaluating collagen supplements for aging include:
- Collagen production naturally decreases with age, contributing to skin aging and joint issues
- Non-animal sources of collagen do not exist naturally, but plant-based collagen "boosters" or "builders" are available, containing ingredients like vitamin C, silica, zinc, and amino acids that support natural collagen production
- The effectiveness of these plant-based alternatives compared to animal-derived collagen supplements is less studied
- Other factors, such as retinoids and vitamin C, have been shown to have therapeutic effects on photoaged skin 2, 3
- Aging is a complex process, and research on aging biology has focused on elucidating the biochemical and genetic pathways that contribute to aging over time, with several potential therapeutic strategies being explored 4
