Fish collagen peptide is a small molecule collagen extracted from fish (especially fish skin, scales, and other parts), which is more easily absorbed by the human body after hydrolysis. In recent years, it has received widespread attention due to its potential health and beauty benefits. The following are its main benefits and scientific basis:
- Promote skin health
Improve elasticity and moisturization:
Collagen is the main structural protein of the skin. Supplementing fish collagen peptides can stimulate fibroblast proliferation, increase the content of type I collagen (mainly present in the dermis layer) in the skin, thereby enhancing skin elasticity and reducing fine lines. Research has shown that supplementing 10-20 grams daily for more than 8 weeks can significantly improve skin moisture and radiance (Journal of Cosmetic Dermatology, 2019).
Antioxidant and anti-aging: Some fish collagen peptides contain antioxidant amino acids such as glycine and proline, which can neutralize free radicals and slow down photoaging (such as UV damage). - Support joint and bone health
Relieve symptoms of arthritis: Fish collagen peptides may alleviate pain and stiffness in patients with osteoarthritis by inhibiting inflammatory factors such as IL-6 and promoting chondrocyte regeneration (International Journal of Medical Sciences, 2018).
Enhance bone density: Its rich hydroxyproline is a key component of bone mineral deposition, and long-term supplementation may help prevent osteoporosis. - Accelerate wound repair and tissue regeneration
Small molecule peptides can be quickly absorbed, providing raw materials for wound repair, promoting collagen synthesis, and accelerating the healing of postoperative or skin injuries. - Other potential benefits
Muscle maintenance: Collagen accounts for 1-10% of muscle tissue, and supplementation may reduce muscle damage after exercise (especially for the elderly or athletes).
Intestinal health: Some studies suggest that it may repair the intestinal mucosa.
Hair and nails: By providing the amino acids required for keratin synthesis, it may reduce nail fragility and hair loss.
precautions
Absorption efficiency: The molecular weight of fish collagen peptides is usually less than 3000 daltons, and the absorption rate is higher than that of ordinary collagen (such as pig/cow sources).
Safety: Most studies have shown high safety, but individuals with allergies (especially to fish) should be cautious.
Suggested pairing: Supplementing with vitamin C can promote collagen synthesis; Taking it on an empty stomach is better for absorption.
