For adults

The daily dose of vitamin C required daily for women over 19 years of age is 75 mg, and for men of the same age - 90 mg.

For the elderly

After 55-60 years, the human body begins to gradually fade. The synthesis of male and female hormones, slow down metabolic processes. Immunity becomes lower, and the risk of getting sick increases. In old age, special support for the body is required. The daily dose in this case is 100-110 mg.

For a cold

With colds and other diseases, the human immune system cannot cope with the enormous burden that has fallen on it and needs outside help.

Ascorbic acid plays a huge role in tissue restoration, strengthening immunity, and endurance. In addition, this substance affects the absorption of protein, which is necessary for rapid growth muscle mass And high efficiency training.

Ascorbic acid is also necessary to compensate for oxidative stress that appears during prolonged exercise. This substance is involved in the synthesis of hormones, including steroids, which increase athletic performance.

If daily requirement for an adult it is 90-100 mg per day, while for an athlete this figure is higher – 150-200 mg per day.

Important! The daily dose of ascorbic acid must be divided into several doses. After all, this substance is not able to accumulate in tissues and is consumed almost immediately as it is received. It is much more effective for health improvement to constantly maintain the necessary content, which is achieved by fractional intake. In addition, it is recommended to increase and decrease the dosage of ascorbic acid gradually.

Remember, vitamin C is a substance, the excess and deficiency of which negatively affects the functioning of all organs and systems human body. When used in the form of tablets and other drugs, it is recommended to periodically monitor blood pressure and kidney function.
