🧪 Formulation Notes

Right For Your Type A Multimineral supplement of exceptional purity for type A individuals

Multimineral supplement of exceptional purity for type A individuals

Stearate free encapsulation

Phytocal A was designed by Dr. Peter D'Adamo and features a unique source of minerals: "Maerl" a small red seaweed (Lithothamnium) found only in isolated areas off the coast of Ireland. Of all sources of calcium, Maerl has one of the lowest levels of undesirable contaminants. Its unique structure gives it a great versatility, and when woven into formulas tailored for the genetics of type A, insures a phenomenal rate of bioavailability and utilization.

This product contains no sugar, salt, gluten, yeast, corn, milk or egg products, no preservatives, color or flavors, and no artificial ingredients.
