What it's built to support
Three pathways, one daily serving
Every ingredient earns its place. Here is how the formula is designed to support normal cardiovascular wellness — described in plain structure/function language.
Cellular energy support
CoQ10 and L-carnitine are involved in how cells produce and use energy — a demanding job for a hard-working heart. This blend is formulated to support normal cellular energy production.
Vascular integrity & calcium utilization support
Vitamin K2 (MK-7) and vitamin D3 are studied for their role in how the body directs and uses calcium. Together they are included to support normal vascular and calcium-utilization pathways.
Healthy homocysteine metabolism support
Active B6, methylfolate, methyl-B12, and TMG participate in the methylation cycle that keeps homocysteine metabolism running normally. They are included to support healthy homocysteine metabolism already within a normal range.
Inside every serving
Three purpose-built blends
Well-studied nutrients in transparent amounts — including the active, bioavailable forms of the B vitamins. No proprietary mystery blends; every microgram is on the label.
