Vitamin C

Healing Properties

Muscle Retention

Positive associations, of both dietary and circulating vitamin C with measures of skeletal muscle mass in middle- and older-aged men and women, suggest that dietary vitamin C intake may be useful for reducing age-related muscle loss.[1]

Skin Health

Collagen Production

Vitamin C is associated with significantly increased collagen production.[2]

  • Method of action: increased mRNA expression of procollagen and elastin in fibroblasts.[2:1]

Disease / Symptom Treatment

Sarcopenia

Sarcopenia is characterized by a progressive and generalized loss of skeletal muscle mass and strength.

Studies have shown significant positive associations between both dietary and circulating vitamin C and measures of skeletal muscle in a large cohort of free-living middle- and older-aged men and women.[1:1]

Ensuring sufficient dietary vitamin C intake, by promoting a diet rich in fruits and vegetables, may help to reduce age-related loss of skeletal muscle and thus have wide-reaching public health benefit.[1:2]
