Vitamin C with citrus bioflavonoids from oranges – the way they're found in nature.

Vitamin C with flavonoids optimizes the beneficial effects of vitamin C – including support of immune function and promotion of wound healing – by replicating the way it's found in nature

Vitamin C (ascorbic acid) is a key antioxidant, protecting cells throughout the body from free radical damage. It plays an integral role in the production of cellular energy, and is essential for the proper metabolism of carbohydrates and the synthesis of fats and proteins. Vitamin C also helps break down cholesterol, promotes wound healing, and helps maintain healthy immune function. Thorne's Vitamin C with Flavonoids contains ascorbic acid and citrus flavonoids. The flavonoids are a mixture of naturally-occurring flavonoids, including rutin, hesperidin, and quercetin. And there is no corn starch contained in this supplement, as it is in many other vitamin C supplements. Although ascorbic acid will work in the body without flavonoids, it works better when accompanied by flavonoid molecules, because the bioflavonoids spare vitamin C, thus providing greater antioxidant capacity.

Vitamin C is an essential, water-soluble antioxidant that can enhance collagen stabilization. A vitamin C deficiency can result in poor collagen cross-linkage and weaker connective tissue. Vitamin C promotes wound healing because it is a cofactor in the synthesis of collagen and other connective tissue components.

Because bioflavonoids have some of the same mechanisms of action as vitamin C, they can potentiate the effect of ascorbic acid. Vitamin C and bioflavonoids both support immune function, connective tissue formation, cellular energy production, and antioxidant activity. Factors dictating a need for higher vitamin C intake include smoking, alcohol ingestion, stress, diabetes, environmental toxicity, and the use of certain medications.

Vitamin C also serves as a cofactor in the synthesis of important neurotransmitters in the body, such as dopamine and norepinephrine.

Using to help keep virus' at bay or away. So far have not gotten sick this season. Taking in combination with Red Marine Algae Plus and vitamin C. Product arrived fast, as described. No flavor, after taste or side effects.

Thanks for your feedback!

Best so far

This product is quite pricey as are Thorne's other products. However, it has been great on my stomach, and my husbands. We take 2 in the morning and 2 in the evening without any problems. We need a lot of vitamin C for pyrolle disorder and undermethylation but many brands cause problems, expecially the powders. So would recommend this for anyone.

Thanks for your feedback!

Thorne is altijd goed! Zuiver preparaat.

Wij bestellen met regelmaat meerdere preparaten van Thorne Research. Geen onnodige vulstoffen of andere toevoegingen die niets met te maken hebben met de basis ingrediënten. De formules zijn vaak doordacht samengesteld. Wat mij betreft één van de fabrikanten die goed weten waar ze mee bezig zijn.
