Ascorbic acid is very easily lost to the urine, so avoid taking the recommended dose all at once. This will cause the blood levels of vitamin C to rise and then plummet. Take vitamin C in smaller doses throughout the day, or buy a time release capsule or sustained release tablet.
For best absorption, take vitamin C with food. Consider taking a form of vitamin C that includes the bioflavonoids. These work synergistically with vitamin C.
Sources of vitamin C include sweet peppers, kale, collard and turnip greens, broccoli, strawberries, papaya, citrus fruits, mangoes, cantaloupe, and cabbage.
Vitamins are organic compounds that serve as helpers to other nutrients in the biochemical processes of digestion, absorption, and metabolism. There are two types: water soluble and fat soluble. The water soluble vitamins are vitamin C, thiamine, riboflavin, niacin, pyridoxine, folacin, cobalamin, biotin, and pantothenic acid.
These vitamins are particularly vulnerable to light, heat, and air. Therefore, fresh, raw fruits and vegetables have higher concentrations of the water soluble vitamins than cooked or aged produce.
