If your body is not absorbing certain nutrients properly, your doctor may suggest you consider taking a supplement for that nutrient.
While it is unlikely to get too much of a nutrient if you are taking a supplement, getting too much, known as toxicity, is possible. It's recommended to confirm a deficiency through testing and talk with your doctor prior to taking supplements.
Water-soluble and fat-soluble vitamins differ in how they are absorbed by the human body.
A water-soluble vitamin dissolves in water and is easily absorbed by the body. Your body does not store these vitamins for long, so any extra will be eliminated in your urine. Because of this, it's important to consume them every day.
A fat-soluble vitamin dissolves in fats and oils and is absorbed with the fats you eat. Your body stores any extra in your liver or fatty tissues. Because of this, you don't need to consume them every day.
