Formulation Notes

Vitamin C is one of the most popular antioxidants known to man, but did you know... most vitamin C has poor bioavailability, meaning you can not absorb it well? Ti-Tech's Vitamin C with bioflavonoids solves the bioavailability problem with advanced Cyclosome liposomal delivery technology - using all natural ingredients so you can absorb more. Liposomes (made from a good fat from phospholipids) protect the vitamin C and may ease digestion, plus cyclodextrin (made from a natural starch) for optimal absorption technology. Vitamin C with high bioavailability is essential, as it is an important nutrient for promoting immune system health, collagen synthesis, antioxidants and much more. Studies have shown the benefits of high bioavailability vitamin C may be more vast than previously though. Absorb more with the next generation of vitamin C.
