POWERFUL COMBO – Vitamins D3 & K2 are natural partners. Most know the benefits of Vitamin D (maintaining strong bones, immune system support, healthy muscle function, etc.), but many don’t realize that Vitamin D benefits are enhanced when combined with Vitamin K2. Our powerful D3 + K2 formula is designed to help optimize your health.

PREMIUM QUALITY – Each liquid drop contains 1,400 IU of Vitamin D3 and 25mcg of Vitamin K (as MK-7), the form of K2 with the highest bioavailability. In addition, our liquid base includes MCT oil which has many benefits including enhanced metabolism and improved energy levels.

THE LIQUID ADVANTAGE – Aside from being easier to consume, liquid drops may also have a comparatively higher absorption rate when compared to supplements in solid form. Combining high quality ingredients with a higher absorption rate is what we like to refer to as the “Liquid Advantage.”

USDA ORGANIC – Just the good stuff, no preservatives, non-GMO, made with organic ingredients. NO gluten, sugar, milk, yeast, salt, or wheat. No unnecessary fillers are used.
