Peptides are a type of chemical compounds composed of amino acid residues connected by peptide bonds.

In simpler terms, peptides are part of proteins – the building material for the entire organism. They are responsible for physiological and metabolic processes in the body, as well as for the health and youthfulness of our cells.

Many peptides and amino acids are synthesized by the body, meaning they are produced within the organism. However, under the influence of stress, illnesses, intense physical exertion, and with age, the production of peptides by the body decreases. This reflects on physiological processes, slowing down cell regeneration and causing aging.

Synthesized and Non-Synthesized Amino Acids

Amino acids can be either replaceable (synthesized in the living organism) or indispensable (non-synthesized). The latter must necessarily enter the body from external sources, namely through food.

Replaceable amino acids: asparagine, glutamine, aspartic acid, glutamic acid, proline, glycine, alanine, tyrosine, serine, cysteine, and so on. Indispensable amino acids: leucine, lysine, valine, isoleucine, tryptophan, threonine, methionine, phenylalanine. Peptides with a sequence of fewer than 10-20 amino acid residues are called oligopeptides (“few” in Greek). Those with greater length are termed polypeptides (“many” in Greek). Short peptides typically have only 2-4 links.

Table of Essential Amino Acids for the Body

Peptide	Amino Acid Status	Food Source Containing the Peptide	Importance	Synthesis
Leucine	Indispensable	Milk, eggs, corn, chicken	Stimulates protein synthesis, normalizes blood sugar, acts as a catalyst for muscle growth, protects muscles from breakdown and injury	Not synthesized
Lysine	Indispensable	Soy, beef, milk	Ensures the synthesis of antibodies, hormones, and enzymes, accelerates recovery after illness, neutralizes viruses	Not synthesized
Valine	Indispensable	Dried beef, milk, corn, eggs	Provides metabolism in muscles, stabilizes hormonal balance, restores damaged tissues	Not synthesized
Phenylalanine	Indispensable	Grains, brown rice, eggs	Enhances memory, improves mental abilities, suppresses appetite, elevates mood	Not synthesized
Threonine	Indispensable	Corn, soy, eggs	Ensures the growth of skeletal muscles, strengthens immunity, normalizes fat metabolism	Not synthesized
Tryptophan	Indispensable	Cassava, milk, eggs	Stabilizes mood, regulates sleep, controls appetite, enhances productivity	Not synthesized
Methionine	Indispensable	Beef, grains, eggs	Promotes fat processing	Not synthesized
Isoleucine	Indispensable	Corn, chicken, potatoes, eggs	Ensures the synthesis of hemoglobin, stabilizes blood sugar levels	Not synthesized
Histidine	Considered “Indispensable” in childhood	Fish, beef, cheese	Protects against radiation, absorbs UV rays, activates hemoglobin synthesis, accelerates tissue regeneration	Transitions to the category of “replaceable” in adulthood

How to Provide the Body with Essential Peptides

The table above lists foods that, when included in your diet, will provide the necessary amino acids for the full functioning of the body

It is important to consider that indispensable amino acids are particularly intensively expended during heavy physical exertion. Therefore, BCAAs with short peptides like IPH are recommended for regular intake by athletes and individuals engaged in strenuous labor.

Regular consumption of such a peptide complex will not only help build muscle and eliminate excess fat deposits but also strengthen the immune system, restore damaged tissues, and reduce the risk of developing heart diseases.
