Vitamin C (ascorbic acid) is one of the most well known
nutrients worldwide. Such recognition is deserved, considering its role
in nutritional biochemistry. Not only is vitamin C a key antioxidant,
protecting cells throughout the body from free radical damage, this
water-soluble vitamin serves as a cofactor in the synthesis of important
neurotransmitters, such as dopamine and norepinephrine, and plays an
integral role in the production of cellular energy.* Vitamin C is
essential for proper metabolism of carbohydrates and synthesis of fats
and proteins.* It helps break down cholesterol and also helps maintain
healthy immune function.* Vitamin C promotes wound healing because it is
a cofactor for the synthesis of collagen and other connective tissue
The term ascorbic acid refers to vitamin C in its
purest form, not bound to any other compound. Thorne's Vitamin C with
Flavonoids contains ascorbic acid and citrus flavonoids (a mixture of
naturally-occurring flavonoids, including rutin, hesperidin, and
quercetin), and is 100 percent pure. Unlike many vitamin C supplements
from other companies, Thorne's vitamin C supplements contain no corn
starch. Although it is not true that ascorbic acid will not work in the
body without flavonoids, vitamin C does work better when accompanied by
flavonoid molecules, as their presence in cells spares vitamin C and
provides greater antioxidant activity.*
Vitamin C is an
essential, water-soluble antioxidant for collagen stabilization.* A
deficiency can result in poor collagen cross-linkage and weaker
connective tissue.* Bioflavonoids have some of the same mechanisms of
action, potentiating the effect of ascorbic acid.*
In addition to
immune support, connective tissue support, and its role in cellular
energy production, antioxidant activity is one of the primary reasons
for vitamin C supplementation.* In addition to strong antioxidant
activity, flavonoids support other key functions in the body.* Factors
dictating higher vitamin C include smoking, alcohol ingestion, stress,
diabetes, pregnancy, environmental toxicity, and the use of certain
