Vitamins are essential for the body to function optimally, and they can be divided into two main categories: water-soluble and fat-soluble. Water-soluble vitamins, mainly B and C, dissolve in the body's water and are easily lost through urine. On the other hand, fat-soluble vitamins (A, D, E, and K) are absorbed along with the fats you eat and stored in the body. The most significant difference between these two types of vitamins is how they are absorbed and stored in the body.
Water-soluble vitamins dissolve quickly in water and are not stored in the body. Once the required amount of vitamins is absorbed, any excess is released and eliminated. On the contrary, fat-soluble vitamins dissolve in fat and are stored in tissues, so the body has access to them when it needs them. This implies that it would be easier to absorb more fat-soluble vitamins than are actually needed, since the kidneys don't eliminate them once the needs are met.
The amount allowed for children and adults varies, so it is important to talk to your healthcare provider if you are taking or planning to take these vitamins to ensure that you stay within a safe daily intake range. Taking too much of these vitamins could cause a variety of health problems such as birth defects, blurred vision, heart rhythm problems, and liver problems.
