Bolster Your Amino Acids

Amino acids, simply put, are organic compounds that make up proteins and are essential to human metabolism. Though they don’t receive nearly as much mention in nutrition discussions as vitamins and minerals, amino acids are just as necessary to our health. Let’s take a closer look at some of the most important amino acids in terms of boosting your metabolism – and protecting your brain:

Arginine: This amino acid is partially converted into a chemical known as spermine, which is believed to help the brain process memory. Low levels of spermine often signal age-related memory loss. Arginine has also shown importance in immune function.

Choline: The brain uses this amino acid to manufacture a memory-related neurotransmitter called acetylcholine. Older people are encouraged to take choline supplements (no more than 3.5 grams per day) because we tend to produce less acetylcholine as we age, putting us at greater risk of memory impairment. Choline is also important for the transport and metabolism of cholesterol. Dietary sources of choline include cabbage, cauliflower, eggs, peanuts, and lecithin.

Glutamine: This amino acid is a precursor of a calming neurotransmitter known as GABA. It helps improve clarity of thought and boosts alertness by assisting in the manufacture of glutamic acid, a compound known for its ability to eliminate metabolic wastes in the brain. Glutamine is also a necessary fuel for intestinal cells.

Methionine: Like glutamine, this amino acid helps cleanse the brain of damaging metabolic wastes. It is an effective antioxidant and helps reduce brain levels of dangerous heavy metals such as mercury.
