Its dramatic age-related decline is significant: plasma concentrations average 200 ng/mL at age 20 but typically plummet to 80 ng/mL by age 60a 60% reduction correlating with visible aging and reduced healing capacity
In the early stages of atherosclerosis, macrophages bind to lipopolysaccharides to promote cholesterol accumulation, lipid accumulation in plaques, and foam cell formation, which is a hallmark of atherosclerotic lesions
Collagen hydrolysates (composed of dipeptides and tripeptides), thought to be resistant to peptidase activity during digestion [27, 29], can enter the blood and be subsequently transported to the skin to yield positive effects on hydration and elasticity and improve wrinkles, particularly in aging women [26,27,28,29, 31]
Its deficiency can lead to fatigue and lethargy
Given the lifelong need for B12 therapy in deficiency-prone populations, the selection of the most patient-friendly and economically sustainable option is critical
