Amino acid food supplements

Water and protein are the building blocks of life—and amino acids are the smallest components that make up proteins. Just 20 amino acids are enough for your body to create all the protein structures it needs to function, thrive, and repair.

But not all amino acids are created equal. They fall into different categories, each playing a unique role in keeping your body running smoothly.

These nine amino acids cannot be made by your body—you need to get them from food or supplements:

Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, Valine.

These amino acids are produced by your body—but that doesn’t mean they’re less important. Examples include: Alanine, Asparagine, Glutamic acid, Serine

They’re crucial for your metabolism and overall biochemical balance.

They may sound “optional,” but under stress, physical strain, illness, or during growth phases, they become absolutely vital—especially for infants, adolescents, and those with metabolic conditions. Key players include: Arginine, Cysteine, Glutamine, Tyrosine.

They help maintain amino acid balance and ensure optimal use of all protein building blocks.

There are over 400 known amino acids that don’t go into protein building, but still have major roles in your body. These include:

• Homocysteine – involved in metabolism

• GABA – a key neurotransmitter

• L-Thyroxine – a hormone precursor

You meet your protein and amino acid needs through both plant-based and animal-based foods. Animal proteins are more similar to your body’s own and are typically better absorbed. Plant-based sources are incredibly valuable too—just often need higher intake or smart combinations.

Generally lower in fat and rich in health-boosting plant compounds, these sources include:

Though eggs are often used as a reference for protein quality, other foods offer even more usable protein:

Proteins are made of anywhere from 100 to 22,000 amino acids, linked in a unique sequence (called the primary structure). This order determines what each protein does in your body.

Smaller chains have names too:

• Dipeptides (2 amino acids)

• Tripeptides (3)

• Oligopeptides (up to 10)

• Polypeptides (more than 10)

Amino acids don’t just link up—they can also be converted into each other. For example, cysteine is made from methionine. In conditions like phenylketonuria, the body can’t convert phenylalanine into tyrosine—meaning phenylalanine must be limited and tyrosine supplemented.

Important to know: The amino acid you get the least of through food limits how much protein your body can build. This is called the limiting amino acid. If it’s missing, protein synthesis grinds to a halt.

This explains why stress, illness, poor diet, or extreme exertion can throw off your amino acid balance.

Proteins are broken down in the small intestine into amino acids—the end result of digestion. These are absorbed into the bloodstream via the intestinal villi and pass through the liver, where they’re used to build blood proteins and support every cell in your body.

If your liver is strained—due to poor diet, illness, or alcohol—this conversion can be disrupted.

If you consume excess protein, your body uses it for energy. But if protein is lacking, you risk energy depletion.

A shortage of carbohydrates can also disrupt amino acid metabolism. In such cases, the body breaks down its own protein to produce glucose. With sufficient carbs, the body can manufacture non-essential amino acids from carbs and fats instead.

You might benefit from supplementation if you’re experiencing:

• Monotonous or low-protein diets

• Low-carb phases

• Food intolerances

• High athletic performance

• Stress, illness, or recovery periods

In these situations, balanced amino acid supplements—or individual amino acids—can help support your body’s needs and boost your well-being.

We offer a wide range of premium amino acid supplements—in convenient capsules or ready-to-mix powder sticks.These carefully formulated dietary supplements help you meet your needs for essential and semi-essential amino acids, which often cannot be sufficiently obtained through diet alone.

From muscle building and recovery to everyday wellness, we’ve got you covered. Try:

• Aufbau Formula B-Map® with 12 amino acids in one capsule complex

• BIOGENA Sports Potassium Magnesium Powder with L-glutamine—ideal for athletes

Biological value measures how well a protein provides essential amino acids. Animal proteins usually rank higher because they contain all essential amino acids in ideal ratios. But plant proteins can be just as powerful when smartly combined—or paired with supplements to fill the gaps.
