الإجابة باختصار

Marine collagen is mostly type I, the type dominant in skin, and its smaller peptides absorb slightly faster. Bovine supplies types I and III, which suits skin and joints together. For skin outcomes the difference in trials is small; choose marine if you avoid bovine sources.

أسئلة شائعة

Is marine or bovine collagen better?
Marine collagen is predominantly type I (skin, hair, nails) and has higher bioavailability due to smaller peptide size. Bovine is type I and III (skin + connective tissue). For skin, marine is slightly superior. Bovine is more cost-effective and widely available.
Is marine collagen halal in UAE?
Fish-sourced marine collagen is halal when derived from permissible fish species and processed without haram additives. Check certification — porcine (pig) collagen exists and is haram. Marine collagen is often a safer halal choice than bovine.
What is the effective dose of collagen per day?
2.5–10g hydrolyzed collagen daily. Studies on skin use 2.5–5g. Joint studies use 5–10g. Most products provide 5–10g per serving. Higher doses have not shown additional benefit.
Can I get enough collagen from food instead of supplements?
Bone broth, chicken skin, and fish skin are rich in collagen. However, cooking denatures collagen — the bioavailable peptides in supplements are specifically hydrolyzed for absorption. Food sources are beneficial but less predictable in dose.
