Citrigen provides a high, pure concentration of grapefruit seed extract along with synergistic herbs known for their ability to combat infectious micro-organisms. Grapefruit seed extract possesses powerful and effective properties that limit the reproduction of germs, parasites and fungi. Research shows that environmental pollutants, lack of exercise and inadequate nutrition can lead to increased allergies, and parasitic and bacterial infections which, in turn, release toxins into cells, damaging tissue and leading to chronic degenerative disease. Citrigen is indicated for parasitic, bacterial and viral infections, streptococcus and staphylococcus; for candidiasis, and yeast, urinary tract and bladder infections; and for intestinal flu and food sensitivities. The capsules in this formula are from a vegetable source making it suitable for vegetarians and vegans.
