Grapefruit Seed Extract is a dietary supplement that is obtained from the extraction of the beneficial active principles contained in grapefruit seeds, mainly bioflavonoids and vitamin C. Bioflavonoids can contribute to a balance of the microbiota. Vitamin C contributes to the normal functioning of the immune system, to protect cells against oxidative damage and helps reduce tiredness and fatigue. In 1980, in a small town in Florida, Dr. HARICH, a gardening enthusiast, observed that the grapefruit seeds found in his compost did not rot. Out of curiosity, the renowned doctor, physicist and immunologist decided to take a closer look at the strange phenomenon and discovered that the components of this simple seed appeared to have germicidal properties. From then on, the extract of grapefruit seeds began to be obtained to apply it to different uses in health. It is highly recommended both at home and when traveling. It does not destroy beneficial bacteria (for example, it does not affect bifidobacteria, keeping the intestinal flora intact). The absence of benzethonium or other preservatives is guaranteed. It is a high quality ecological product. It is recommended to dilute 15 drops (0.8 ml) in water or fruit juice three times a day, or as directed by a healthcare professional. Shake well before use. Food supplements should not be used as a substitute for a balanced and varied diet and a healthy lifestyle. Do not exceed the recommended daily dose. Only recommended for adults. Keep out of reach of young children.
