Examples of such diseases are celiac disease (chronic nutritional disorder), cystic fibrosis, and cholestasis (bile-flow failure or interference).
Vitamin treatment is important during specific diseases where the body's normal processing of a vitamin is impaired.
Vitamin C is known to enhance iron absorption from the intestinal tract by promoting the conversion of non-heme iron (plant-based) to a form that is more easily absorbed by the body. Conversely, substances like tannins and phytates found in tea, coffee, and whole grains can inhibit iron absorption.
Yes, high calcium intake can inhibit the absorption of iron in the body.
No.

Vitamin C actually enhances the absorption of non-heme iron (the type of iron found in plant-based foods) rather than slowing it down. It does this by converting iron to a more absorbable form and by preventing the formation of insoluble complexes that can inhibit absorption. However, high doses of vitamin C can interact with certain iron supplements, potentially affecting their absorption. Overall, vitamin C is beneficial for iron absorption when consumed together with iron-rich foods.
Consuming zinc with a source of protein, such as meat, fish, poultry, or nuts, can increase its absorption. Foods high in phytates, such as whole grains and legumes, can inhibit zinc absorption. Vitamin C and animal sources of heme iron can also enhance zinc absorption.
vitamin A
No niacin does not inhibit weight loss. It is just a B vitamin.
Animal studies have concluded that vitamin C enhances chromium absorption of insulin.
Vitamin A increases the absorption of magnesium.
Stimulants like caffeine can decrease the absorption of vitamin C in the body, leading to lower effectiveness of the vitamin.
