What are vitamins supplements ?
Vitamin supplements are necessary supplements to treat vitamin deficiencies. They are concentrated vitamin preparations used to fill nutritional gaps in the daily diet. Vitamin supplements come in the form of tablets, gummies, liquids or powders. They also provide the body with essential nutrients to help maintain health or improve specific problems (such as immunity, fatigue, skin aging, etc.).
Catorgies of vitamins supplements
Common vitamin supplements are divided into two categories: fat-soluble vitamins and water-soluble vitamins. Fat-soluble vitamins include: VA, VD, VE, VK , etc. Water-soluble vitamins include: niacin, folic acid, Vitamin C and B vitamins, etc. B vitamins include: VB1, VB2, VB6 and VB12. It can be said that vitamin supplements are a must-have for many families.
Like other lipids, most fat-soluble vitamins are first absorbed into the lymph and then transported in the blood, bound to protein carriers within cells. Fat-soluble vitamins may be stored in the liver or in adipose tissue along with other lipids, and some of these vitamins may accumulate to toxic concentrations. Water-soluble vitamins, on the other hand, are absorbed directly into the bloodstream, where they flow freely. Most water-soluble vitamins are not stored in tissues in significant amounts; instead, the excess is excreted in the urine. Therefore, the risk of toxicity from water-soluble vitamins is not as great as with fat-soluble vitamins.

Focus on quality. The most important thing to consider to choose the right vitamin supplements is the quality of the supplement. When it comes to quality, there are several aspects to consider. The first is accuracy of ingredients. Vitamin supplements need to have a clean ingredient list and the content of ingredients must be accurate. And the second is product testing. Vitamin supplements need to pass microbiological testing and have product testing reports. Supplements cannot contain unnecessary impurities. If the product passes the test, its label may have a certification mark from the testing agency. It is important to note that false “copycat” marks are prevalent and can even deceive cautious consumers into buying untested products.

Pay attention to the time of taking
Taking vitamin supplements after meals can reduce irritation to the gastrointestinal tract and promote the absorption of vitamins. This is because the fat and other ingredients in food help the dissolution and absorption of fat-soluble vitamins.
Avoid interactions with drugs. Certain drugs may interact with vitamins, affecting their absorption and utilization. For example, aluminum hydroxide can reduce bile acid in the upper small intestine, affecting the absorption of vitamin A. Cholestyramine can bind to vitamin B12 and reduce its absorption.
