Amino acids are the building blocks of proteins and help repair and build tissue, cells, and muscles. They also improve memory function and mood. There are many different types of amino acids found within proteins. The essential ones are: 

• Histidine

• Isoleucine

• Leucine

• Lysine

• Methionine

• Phenylalanine

• Threonine

• Tryptophan

• Valine

Selenium is a nutrient that helps your body is a variety of ways. It is important for fighting free radicals and infections, repairing DNA, thyroid gland function and metabolism. It is critical to fertility and reproduction, and is suggested to reduce the chance of a miscarriage. 

Vitamin A (retinol) is essential for good eyesight and extremely helpful in preserving our skin, joints, eyes and internal organs. If there really was a Fountain of Youth, retinol would be one of the key ingredients and it would probably be reddish-orange due to the beta-Carotene. The body converts the red-orange pigment into Vitamin A. It also supports the immune system, bone metabolism, and development of embryos in reproduction. It is an antioxidant vitamin, which destroys free radicals in our body. Free radicals are produced by the body when we smoke, don’t eat a proper diet, or are exposed to stress or pollution. They are also suspected of contributing to cancer and cardiovascular disease. Pregnant women who are deficient in Vitamin A are more likely to have premature birth or very low birth weight. Women who have high levels of Vitamin A have a lower risk for breast cancer.

Vitamin A is made by your body when you eat carrots and other yellow and orange fruits and vegetables which contain beta-carotene, such as sweet potatoes, pumpkin, cantaloupe, papaya, peas, butternut squash, mango, and dried apricots. It is also found in spinach, kale, collard greens, broccoli, tomato juice, peppers, watercress and full fat dairy products (butter, milk, eggs, cheddar cheese). Interestingly enough, these are ready to eat raw and cooking them causes the loss of some of the vitamins. Liver, beef, chicken, turkey, and fish are also high in Vitamin A content. 

Vitamin B12 (cobalamin) helps break down and use the fuel from the foods you eat, helps your brain and spinal cord function properly and helps your body produce blood.

Deficiency of B12 results in memory loss, anemia, mania, psychosis, and even paralysis. Unlike the other B Vitamins,

B12 cannot be found in plants. Only meat, fish, eggs or dairy products contain B12.

Vitamin B3 (niacin) helps your body grow but it specializes in the repair of nerves and skin cells and managing cholesterol levels.

Without niacin you would be mentally confused and likely to suffer from weakness, aggression, dermatitis, insomnia, and possibly death.

Vitamin B5 (pantothenic acid) helps your body turn fats and carbohydrates into usable energy, improves agility, prevent acne, and helps your body produce the healthy fats it needs.

Deficiencies in B5 will lead to weakness, numbness, fatigue, and sometimes a burning pain in the feet.

Cauliflower, mushrooms, sunflower seeds, yogurt, calf’s liver, corn, broccoli, squash or eggs supply B5.

Vitamin B7 (biotin) helps promote hair growth and helps maintain a healthy scalp. It is essential for healthy babies.

Deficiencies in biotin can cause brittle hair, but more importantly, women who are deficient in Vitamin B7 are more likely to give birth to infants with impaired growth and neurological disorders.

Vitamin Bp (choline) is an essential nutrient that can be found in beef liver, eggs, cod fish, chicken, milk, soy lecithin, cauliflower, spinach, wheat germ, kidney beans, grapefruit, brown rice, peanuts, and almonds.
 
Not getting enough Vitamin Bp in your diet can cause neurological disorders, liver disease, and clogging of the arteries.

Vitamin D helps keep your bones healthy by helping your body absorb the calcium in your diet. It helps prevent rickets in children. 
 
Fish and egg yolks are two of the few natural foods containing Vitamin D, however eating these is not enough. In order for the body to use the vitamin, it requires the help of the sun. The sun turns chemicals in your skin into Vitamin D3, which is carried to your liver and kidneys, where it is transformed into active Vitamin D.
