It's really no surprise... the sun got it right! When the sun's rays touch your skin, your body synthesizes vitamin D, an essential nutrient rapidly rising in reputation as research reaffirms its wide array of health benefits. Formulated to provide support without the burn or for periods of too little sunlight, our high-potency, natural-source supplement provides 5,000 IU of the same form of vitamin D-3 synthesized from sun exposure. For complete synergistic support, we combine D-3 with a serving size of K-2 Menaquinone-7 from fermented chickpea. Together, D-3 & K-2 may help support the transportation and absorption of calcium for healthy bones and teeth, healthy cardiovascular and immune system function, and healthy arteries. Lab tested for potency and purity, Solaray Vitamin D-3 & K-2 gives you the power of the sunshine vitamin‚ without artificial colors, flavors, or preservatives.
