What are Fat Soluble Vitamins For?

Your body needs a small amount of fat soluble vitamins in order to stay in optimal health. Fat soluble vitamins are stored in the liver and fatty tissue, so they take a longer time than water soluble vitamins to be eliminated from the body. Because of this, having an overabundance of these vitamins can be dangerous and lead to toxicity since it takes a longer time to flush the system of fat soluble vitamins.

Deficiency in fat soluble vitamins is rare in the United States (although it is more common in developing countries), so be careful not to overuse supplements of these particular vitamins.

Luckily, Dr. Perricone’s Skin & Total Body supplement is formulated with the correct daily dosage of each fat soluble vitamin so you know you’re getting the right amount.

This article will discuss the fat soluble vitamins that are essential to good health and are found in Dr. Perricone’s Skin & Total Body supplements:


Vitamin A

Vitamin A is important for:

  • Helping eyes adjust to changes in light
  • Helping to regulate the immune system
  • Bone growth
  • Tooth development
  • Reproduction
  • Cell division
  • Cell differentiation (when cells specialize, becoming part of the skin, lungs, brain, or other parts of the body)
  • Gene expression
  • Moistening skin, eyes, and mucous membranes of the nose, mouth, throat, and lungs

Where can you find vitamin A?

There are 2 types:

  1. Preformed vitamin A is found in the form of retinol and is the most usable form of the vitamin. You can find preformed vitamin A in your everyday diet in animal products like whole milk, liver, and eggs.
  2. Provitamin A is found in the form of carotenoids and is converted in part into retinol. Beta-carotene, alpha-carotene, and beta-cryptoxanthin are the most common carotenoids, with beta-carotene being the most easily converted into retinol. Beta-carotene is found naturally in many fruits and vegetables like peaches and carrots.



Vitamin D

Vitamin D is important for:

  • Calcium absorption in the gut
  • Bone growth and remodeling
  • Regulation of neuromuscular and immune function
  • Reduction of inflammation
  • Regulation of gene encoding proteins responsible for the cell’s life cycle

A deficiency in vitamin D can cause brittle, thin, or misshapen bones. It can also cause rickets in children and osteomalacia (i.e. the softening of bones) in adults. Having enough vitamin D in the diet, in addition to calcium, helps to prevent osteoporosis.

Vitamin D isn’t actually in its usable form when it enters the body through sunlight, food, or supplements.

2 reactions have to take place within the body:

  1. One in the liver, which converts it to 25-hydroxyvitamin D.
  2. The other in the kidney, which converts it into the biologically useful form 1,25-dihydroxyvitamin D, otherwise known as calcitrol.

In addition to getting vitamin D from a few natural and fortified foods, your body naturally absorbs vitamin D from sunlight. When ultraviolet rays hit the skin, they begin a reaction that synthesizes vitamin D. In fact, many people meet their need for vitamin D just by being outside a few times a week. Remember, though, always wear sunscreen to avoid the potential harm from UV rays and skin damage.


Vitamin E

Vitamin E is important for:

  • Antioxidant activities that reduce free radicals
  • Proper immune function
  • Cell functioning
  • Regulation of gene expression
  • Other metabolic processes

Vitamin E is the blanket name for a group of 8 different chemicals that have differing amounts of biological use: alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol. However, only alpha-tocopherol has been shown to meet the needs of the human body and thus is the primary form that is found in the Skin & Total Body supplement.


Vitamin K

Vitamin K is important for:

  • Blood coagulation, or clotting
  • Cell growth
  • Bone mineralization (keeps bones dense)

There are two types of vitamin K: one is found in plants, and one is found in bacteria.

Plants make phylloquinone (vitamin K1) and bacteria make a number of forms of the vitamin called megaquinone-n. The bacterial forms are collectively called vitamin K2.

Vitamin K is named for the German word “koagulation” because of its function in assisting blood clotting.

Maintaining the right balance of these vitamins in the body is critical to excellent health and well-being, and Dr. Perricone’s Skin & Total Body supplements allow you to do just that.

  1. Doesn’t VItamin K assist with discoloration around the eye area? I have dark circles and was curious if Vit K supplement would help this problem?
