TherapeuticsMD, Inc., Boca Raton, FL, has launched vitaMedMD Plus Rx, a prescription prenatal vitamin. A single-dose combo-pack contains one prenatal tablet with 16 vitamins and minerals, and one soft gel with 300 mg of plant-based DHA. The product also contains a unique combination of folic acid and the patent-protected fourth generation folate, Quatrefolic. Quatrefolic is structurally analogous to the active form of folic acid and is available for its immediate biological action by bypassing the enzymatic conversion. Additionally, Quatrefolic has greater bioavailability and stability than previous generations of folic acid, according to the company.
