Ascorbic acid(vitamin c)

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that occurs in our food naturally…fortunately! Most of the animals are able to synthesize ascorbic acid in their body. It was first discovered in 1928 and is considered as an essential nutrient. Our body absorbs this vitamin on different levels depending on the dose.

Dosage:

Our body absorbs between 70 to 90 percent of ascorbic acid when taken at 40 to 160 mg/day. Doses higher than 1g/day drop off, as the absorption is less than 50 percent. The rest is excreted in urine within about 20-30 minutes of consumption. For adult men daily intake must be 85mg; for adult women, it is 70 mg; in pregnant women, it is 80 mg; and for breastfeeding women, it is 115mg. An additional 30 mg daily intake is recommended in some individuals, such as smokers. So better watch all the smokers out there!

Deficiency:

Lack of vitamin C means new collagen cannot be formed. This causes various tissues in the body to break down and your body becomes affected. If persists for 2-3 months, this lack can cause a disease known as scurvy.

Its deficiency can cause defects in the formation of intercellular cement substances in connective tissues, bones, and dentin. This results in weak capillaries with hemorrhage and could cause defects in bone.
