Formulation Notes

Benefits of Ultra C Buffered Vitamin C carries a reputation as one of the most powerful forms of natural immune system support. Bioflavonoids are naturally occurring nutrients found in plant life. Studies suggest bioflavonoids contain properties that may enhance the effects of vitamin C. Rosehips contain a substanial dose of vitamin C and are often used for immune support. Therefore, combining rosehips and vitamin C increases the power and efficacy of both supplements.
