Understanding Amino Acids and Their Functions

Amino acids are the building blocks of proteins. They play a key role in your body's functions. These compounds are vital for memory enhancement, neurotransmitter production, and cognitive performance. Let's explore what amino acids are and their impact on your health.

What Are Amino Acids?

Your body needs 20 different amino acids to function properly. These tiny molecules link together to form proteins. Proteins are essential for various bodily processes.

Amino acids help break down food, repair tissues, and support your immune system.

Essential vs. Non-Essential Amino Acids

Amino acids are divided into two categories: essential and non-essential. Your body can produce 11 non-essential amino acids. But, the remaining 9 essential amino acids must come from your diet.

The essential amino acids include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Complete proteins, found in foods like beef, poultry, fish, eggs, and dairy, contain all nine essential amino acids. Incomplete proteins, such as nuts, seeds, and beans, lack one or more essential amino acids. Eating a variety of protein sources ensures you get all the amino acids your body needs for optimal cognitive performance.

Essential Amino Acid	Recommended Daily Allowance (per 2.2 lbs body weight)
Histidine	14 mg
Isoleucine	19 mg
Leucine	42 mg
Lysine	38 mg
Methionine	19 mg
Phenylalanine	33 mg
Threonine	20 mg
Tryptophan	5 mg
Valine	24 mg

How Amino Acids Affect Brain Function

Amino acids are key for keeping your mind sharp and supporting brain health. They are the building blocks of protein and help with neurotransmitter production and energy use in the brain.
