    Absorption
In summary, Vitamin C is primarily absorbed in the small intestine through a process of active transport. Several factors can affect its absorption, including the amount consumed, form, and other substances in the digestive tract. It is possible to consume too much Vitamin C, with recommended daily intake for adults being 75-90mg. Vitamin C cannot be absorbed through the skin and is best consumed through food or supplements. Cooking can also affect its absorption, so it is recommended to cook foods at low heat and consume them quickly.

Is there difference in absorption rate between various berries and fruits due to a place where you and your ancestors have lived?
What I meant, is it true that my organism will absorb vitamin C much better from black currant than from lemon or kiwi (because I live in Baltic states and black currants naturally grow here but lemons are imported)?

I think it is unlikely that there would be.
If there was: it would be due to selection effects, instead of adaptation.
 

1. How is Vitamin C absorbed in the body?

Vitamin C is primarily absorbed in the small intestine through a process called active transport. This means that the body actively transports Vitamin C from the intestine into the bloodstream with the help of specific carrier proteins.

2. What factors can affect the absorption of Vitamin C?

Several factors can affect the absorption of Vitamin C, including the amount consumed, the form of Vitamin C (e.g. ascorbic acid or ascorbate), the presence of other nutrients or substances in the digestive tract, and individual differences in intestinal health and function.

3. Is it possible to consume too much Vitamin C?

Yes, it is possible to consume too much Vitamin C. The recommended daily intake for adults is 75-90mg, and consuming more than 2,000mg per day may lead to adverse effects such as stomach upset, diarrhea, and kidney stones. However, the body can also excrete excess Vitamin C through urine.

4. Can Vitamin C be absorbed through the skin?

No, Vitamin C cannot be absorbed through the skin. It needs to be consumed through food or supplements to be absorbed into the bloodstream. Some skincare products may contain Vitamin C, but its primary purpose is to provide topical benefits rather than being absorbed into the body.

5. Does cooking affect the absorption of Vitamin C?

Yes, cooking can affect the absorption of Vitamin C. Heat, air, and water can cause Vitamin C to break down and reduce its availability in food. To retain the most Vitamin C, it is recommended to cook foods at low heat and for a short time, and to consume them as soon as possible after cooking.
