Formulation Notes

Formula 109 contains a unique, natural combination of Nattokinase and Suntheanine with Aged Garlic Extract to support healthy blood pressure levels, already within normal ranges. Kyolic Aged Garlic Extract (AGE) starts with organically grown garlic. It is then aged using a proprietary process which removes odor-causing compounds attributed to raw garlic and increases the bioavailable, beneficial compounds.
