[37] Natural plant and algae sources of vitamin B 12 include fermented plant foods such as tempeh [86] [87] and seaweed-derived foods such as nori and laverbread
It also stimulates collagen formation, which is essential for tendon, ligament, and joint repair
The presence of this sleep-promoting peptide in milk suggests an evolutionary role in helping newborns establish healthy sleep cycles
In lab and clinical research, its been observed to activate fibroblasts (the cells that produce collagen), increase glycosaminoglycan synthesis (which helps skin retain water), modulate matrix metalloproteinases (MMPs, the enzymes that break down old tissue), and act as a copper cofactor in antioxidant pathways
The peptide accelerates tissue repair while appropriate exercise ensures the new tissue develops proper strength, organization, and resilience
adults have low B12 levels, especially vegetarians, vegans, and older adults
