The main ingredient of the Flavooptic supplement is haskap berry extract. It is the fruit of a tree called Kamchatka honeysuckle, a variety of blue honeysuckle. Its properties have been known for several hundred years and are used in folk medicine in northeast Asia (Russia, China, and Japan). The Ainu - the indigenous people of the Japanese island of Hokkaido, consider these fruits to be "berries of longevity and great eyesight" and gave them the name often used by others - haskap.

Haskap berries are characterized by a much higher content of natural biologically active substances than other berries (e.g., blueberries). It is particularly rich in cyanidins, which give these fruits an intense blue color. These types of natural chemical compounds have been shown in scientific research to have a protective effect on human retinal pigment epithelium cells [5]. Most likely, a substance called cyanidin 3-glucoside (which is especially rich in haskap berries) has the strongest antioxidant effect and inhibits pathological angiogenesis (pathological formation of new vessels) among all anthocyanins [4,5]. This action protects the eyes against diseases such as diabetic retinopathy, macular degeneration, uveitis, and retinal degeneration. Therefore, it also delays the process of eye aging and vision deterioration.

The beneficial health effects of haskap berry extract are not limited only to the eyes and inhibiting the aging process. Young people may be interested in how natural substances from this fruit can influence physical endurance and improve performance during sports. In one study, 30 volunteers aged 26-40 were given a haskap berry preparation for a week and their results were compared in a 5-kilometer run at the beginning and end of the experiment [2]. This was a so-called "double-blind placebo study." This means that both the researchers and the test subjects did not know who was taking haskap berries and who was taking virtually nothing (placebo). It turned out that after 7 days, people taking the fruit preparation ran on average 250 meters/hour faster than at the beginning of the experiment. People taking placebo did not notice any improvement in their results.

The effect of protecting healthy cells against damage and disease processes is not limited only to the structures of the eye. This is most likely a beneficial effect on the entire body. In one of the experiments, a haskap berry preparation effectively protected lung epithelial cell (protected their DNA) against damage caused by substances that cause lung cancer and are found in cigarettes [3]. Researchers believe that this anticancer effect is due to the strong antioxidant and anti-inflammatory effects of bioflavonoids contained in haskap berries. Various scientific studies have shown a beneficial effect of these fruits on episodic memory (memory of events) and blood pressure [1], anti-atherosclerotic effect (through a beneficial effect on cholesterol and triglycerides), protection of liver health, reducing insulin resistance (type 2 diabetes), protecting against the harmful effects of ultraviolet on the skin and even has antibacterial effects (e.g., against Staphylococcus epidermis, Escherichia coli) [4].

The second ingredient of our Flavooptic supplement is micronized fiber (pectin) obtained from a special species of apples characterized by an exceptionally high content of pectin and other natural biologically active substances. Micronized pectin can penetrate the blood and have a beneficial effect on the health of the entire body by inhibiting excessive inflammation and pathological fibrosis (liver cirrhosis, kidney failure, atherosclerosis). Their anticancer effects are also known [6]. This fiber has a beneficial effect on the gastrointestinal flora (as a prebiotic) and thus helps protect the liver against the effects of metabolic and environmental toxins [7]. Adding micronized apple fiber is a brilliant solution to eliminate capsule fillers that are harmful to health (e.g., magnesium stearate). Plants and fruits that are the raw material for our supplements are organically grown in Poland, away from industrial pollution. They are grown in areas with the cleanest and least degraded arable land in Poland and Europe. This guarantees the best possible and ecologically cleanest content of natural active substances.
