Amino Acid #
Amino acids are the building blocks of proteins, and they play a crucial role in Nutritional Psychiatry. There are twenty different amino acids that the human body uses to build and repair tissues, including neurotransmitters and hormones. Related terms include protein, neurotransmitter, and hormone. Amino acids can be classified into two main categories: essential and non-essential. Essential amino acids cannot be produced by the body and must be obtained through the diet, while non-essential amino acids can be produced by the body. Examples of essential amino acids include tryptophan, tyrosine, and phenylalanine, which are important for the production of neurotransmitters such as serotonin, dopamine, and norepinephrine.
Antioxidant #
Antioxidants are substances that neutralize free radicals, which are unstable molecules that can cause oxidative stress and damage to cells. Antioxidants play a crucial role in maintaining overall health and well-being, and they are particularly important in Nutritional Psychiatry. Related terms include free radical, oxidative stress, and inflammation. Antioxidants can be found in a variety of foods, including fruits, vegetables, and nuts. Examples of antioxidants include vitamin C, vitamin E, and beta-carotene. Antioxidants can help to reduce inflammation and oxidative stress, which are associated with a range of mental health conditions, including depression and anxiety.
B Complex Vitamins #
