Vitamin A plays a central role in keeping skin and mucosal surfaces healthy by binding nuclear receptors that regulate epithelial cell turnover, barrier integrity, and local immune responses, including how cytokines are produced and how immune cells move to and protect mucosal tissues. When vitamin A is deficient, those finely tuned controls become unbalanced, leading to rough, dry, or hyperkeratotic skin, more fragile linings in the gut, lungs, and eyes, and a shift toward inflammatory signaling that can leave barriers both irritated and easier for pathogens to breach. For someone dealing with persistently dry, rough skin, frequent chapped lips or mouth sores, or ongoing gut irritation it can be important to consider whether an underlying vitamin A deficiency is quietly undermining the very barriers that are supposed to protect them. This medication is commonly used for High Cholesterol.

Some side effects may be linked to nutrient depletion caused by this medication.
Bile acid sequestrants work by binding to cholesterol and bile acids in the intestine, unfortunately, they can also bind to folic acid, hindering its uptake into the bloodstream. For individuals taking bile acid sequestrants, supplementing with folic acid may be advisable to prevent or address potential deficiencies.
Bile acid sequestrants work by binding to cholesterol and bile acids in the intestine, unfortunately, they can also bind to fat soluble vitamins like vitamin A, hindering its uptake into the bloodstream. For individuals taking bile acid sequestrants, supplementing with vitamin A may be advisable to prevent or address potential deficiencies.
Bile acid sequestrants work by binding to cholesterol and bile acids in the intestine, unfortunately, they can also bind to fat soluble vitamins like vitamin D3, hindering its uptake into the bloodstream. For individuals taking bile acid sequestrants, supplementing with vitamin D3 may be advisable to prevent or address potential deficiencies.
Bile acid sequestrants work by binding to cholesterol and bile acids in the intestine, unfortunately, they can also bind to fat soluble vitamins like vitamin E, hindering its uptake into the bloodstream. For individuals taking bile acid sequestrants, supplementing with vitamin E may be advisable to prevent or address potential deficiencies.
