Other forms of delivery can contain binders and fillers that may cause stomach upset and offer no nutritional value. Advanced Liquid Soft-Gels provide an optimum delivery system. Patented BioPerine for Superior Bioavailability Our research team found a way to further enhance the bioavailability of many ingredients in our formulas. A US parent and several clinical studies demonstrate how BioPerine, an extract of Black Pepper, enhances the bioavailability and absorption of many nutraceuticals. Irwin Naturals Liquid Soft-Gels contain our own BioPerine one step further by combining it with a powerful Ginger extract for enhanced digestion.
