IS THE WHITE VITAMIN C BETTER?

   Vitamin c otherwise known as ascorbic acid can be gotten from fruits and vegetables. However, it is sold in tablets and capsules,
   Historically, vitamin C was used for preventing and treating scurvy. These days, vitamin C is used most often for preventing and treating the common cold. Some people use it for other infections, including gum disease, acne and other skin conditions, bronchitis, human immunodeficiency virus (HIV) disease, stomach ulcers caused by bacteria called Helicobacter pylori, tuberculosis, dysentery (an infection of the lower intestine), and skin infections that produce boils (furunculosis). It is also used for infections or inflammation of the bladder and prostate, nerve pain, and complications during pregnancy. Other uses include increasing the absorption of iron from foods. Vitamin C is also used in combination with a drug called deferoxamine to increase the removal of iron from the blood. Some people use vitamin C to correct a protein imbalance in certain newborns (tyrosinemia).

 It is also used to prevent the transfer of HIV from mothers to babies during breastfeeding. Vitamin C is also used to help reduce the side effects of bowel preparation.
    However, there has been a misconception as to whether the white vitamin c is more efficient than the sweetened vitamin c. The truth, however, is that the sweetened coloured vitamin c is for non-diabetic patients and the white non-sweetened type was made for the diabetic patients who are regulating their sugar consumption.

 The white vitamin c tablet is indeed more acidic than the sweetened one. Whilst the vitamin c tablet may not have a specified dosage, it is advised to be taken moderately. Always talk to your physician.
