Vitamins are divided into two groups according to their chemical properties: water-soluble and fat-soluble vitamins. Since vitamins B and C are water-soluble, they cannot be stored in our body. For this reason, deficiency symptoms are more common than with fat-soluble vitamins. Because they are consumed in excess, they do not accumulate in the body, so they often do not cause any problems.

Just as vitamin deficiency is a health problem, its excess can cause health problems. For this reason, your vitamin supplements should be put together regularly according to your needs and used over the long term.
