There will be no toxic reaction. Read the following text carefully and you will understand. (It won't be toxic, but it's a waste to take too much of it.)

Vitamin C is water-soluble and is absorbed from the upper part of the small intestine, transported to the bloodstream through the portal and hepatic veins, and transferred to tissues in all parts of the body. When a person ingests vitamin C, the pituitary gland and kidneys have the highest concentration of vitamin C, followed by the eye, brain, liver and spleen. When the total body storage of vitamin C is less than 300 milligrams, there is a risk of scurvy, the body's maximum storage capacity of 2000 milligrams.

Vitamin C is excreted by the kidneys, so the kidneys have the function of regulating the rate of vitamin C excretion. When tissues are saturated with vitamin C, excretion increases; when tissues are deficient, excretion decreases.

Oxalic acid is one of the metabolites of vitamin C. Its excretion varies from person to person, with an average of 16-64 MG of oxalic acid being excreted in the urine in an average day. People are worried that

excessive oxalic acid will cause stones. In fact, the amount of oxalic acid in the body, in addition to part of the metabolism of vitamin C, the rest of the majority of the direct intake of food, or metabolism of amino acids produced by the food.

By the experiment, even if the intake of high amounts of vitamin C, the amount of oxalic acid in the urine will not be increased, so do not worry about vitamin C to bring the problem of stones.
