Oral supplementation with hydrolyzed fish cartilage improves the morphological and structural characteristics of the skin: a double-blind, placebo-controlled clinical study
Stimulates collagen and elastin production for firmer, smoother skin. Accelerates wound healing by promoting cell migration and reducing scars. Provides antioxidant protection against free radicals and UV damage. Reduces fine lines, wrinkles, and hyperpigmentation through remodeling. Enhances blood flow and angiogenesis for better nutrient delivery. A 12-week thigh skin study found GHK-Cu improved collagen in 70% of participants versus 50% with vitamin C
Week 24 What you may notice: Reduced pain on familiar movements
Reported applications include NNMT enzyme inhibition assays measuring 1-methylnicotinamide formation or S-adenosylhomocysteine release, intracellular target-engagement assays in differentiated 3T3-L1 adipocytes where 5-Amino-1MQ reduced intracellular 1-methylnicotinamide with an EC near 2.3 M (Neelakantan et al., Biochem Pharmacol, 2018), membrane permeability and Caco-2 transport characterisation, methyltransferase selectivity panels covering COMT, DNMT1 and PRMT3, and rodent studies of NNMT inhibition in adipose tissue and liver following the antisense knockdown work of Kraus and colleagues (Nature, 2014)
