A deficiency in vitamin C, can lead to scurvy which is a disease that is characterized by connective tissue weakness, fatigue, gum disease, poor wound healing, and decreased red blood cells. If you notice your gums bleed often, supplementing with vitamin C or increasing the amount of vitamin C rich foods in your diet may help. Due to it’s immune boosting power, vitamin C is a means to help prevent and/or treat numerous health conditions such as cancer (including prevention and treatment), cardiovascular disease, age-related macular degeneration, cataracts, and the common cold.
Below are a few additional things to know when choosing to supplement Vitamin C:
- Generally there is no difference in the bioavailability of synthetic vs. non-synthetic vitamin C; but research has shown that the bioavailability from natural sources with flavonoids may have greater bioavailability than synthetic forms.
- Vitamin C may increase the absorption of aluminum
- Vitamin C enhances the bodies’ absorption of non-heme iron (plant-based sources of iron) which is great for those who are anemic
- Quercitin and rutin have been shown to inhibit the oxidation of vitamin C in vitro
- Vitamin C may decrease the availability of selenium for absorption. Selenium is a trace mineral that our body needs so if you were deficient, excess vitamin C supplementation could make the issue worse
