Beta-glucans are a group of natural polysaccharides found in the cell walls of yeasts, fungi, some bacteria, and grains such as barley and oats. The chemical structure of beta-glucan varies depending on its source, and this structural difference can affect its biological effects.

In recent years, beta-glucan has become one of the most well‑known and widely studied compounds in the field of immune system health.

Omega‑3 fatty acids are a group of essential polyunsaturated fats that play an important role in maintaining human health. Since the human body cannot produce sufficient amounts of these compounds, they must be obtained through diet or supplements.

The three main members of the omega‑3 family are alpha‑linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). ALA is mainly found in plant sources such as flaxseed and walnuts, while EPA and DHA are primarily found in fatty fish and marine algae.

Human skin naturally contains large amounts of collagen and hyaluronic acid. These two compounds play an essential role in maintaining strength, elasticity, moisture, and a youthful appearance of the skin. With aging, the natural production of collagen and hyaluronic acid in the body declines, which can lead to wrinkles, reduced firmness, and loss of moisture.

Vitamin E is one of the most important fat‑soluble vitamins, known for its strong antioxidant properties. It protects the body’s cells against damage caused by free radicals and plays a role in maintaining skin health, the immune system, cardiovascular health, and many metabolic processes.
