The fact states that the human body is two-third water. Fluids are very essential for humans because of this reason only. Many people are aware of this fact but a few know that the remaining one-third comprises mainly of proteins. Proteins make 17% of human body and the protein is present not only in muscles but other areas as well. The skin, hair, nail et al. are made from proteins. The antibodies and enzymes present in the body are also protein. Hence, there is nothing wrong in saying that proteins are the building blocks of human body. Now, what are proteins made of? Proteins are made of amino acids.

More than twenty amino acids have been identified. Phenylalanine is also among those amino acids that can be considered to be the building blocks of proteins. Now, Phenylalanine is essential because they are not produced within the body. It is vital to intake Phenylalanine through the diet. There are some dietary proteins that include all the requisite amino acids. Sources of such proteins are meat, fish and milk. However, there is another class of proteins as well that contains some of the amino acids, but not all. Vegetables, nuts, beans, etc are sources of such proteins. In this category, the non-vegetarians have an upper hand because their protein intake is satisfactory but the vegetarians have to be careful to make sure that the protein is taken by the body.

Phenylalanine is vital to produce certain critical chemicals for proper functioning of the brain. The mental alertness is greatly improved and so does the sex life. Some Phenylalanine supplements are used as a source of natural anti depressant. However, Phenylalanine side effects are very harmful too. An over-stimulation of the brain is very likely and this problem may lead a person to become insomniac. The chemical produced with the help of Phenylalanine is a very good tranquilizer and sedative. Phenylalanine is a prime choice for athletes to relieve off their pains.

The dosage of Phenylalanine is also very critical and should be kept under control. It is foolishness to take Phenylalanine supplements indefinitely. A better option is to take supplements with multi- amino acid supplements to maintain a balance. Phenylalanine supplementation will only be successful if the dosage is kept under check. It is always recommended to consult a doctor before taking or starting a supplementation to avoid any future adverse effects.
