A DAILY DOSE OF DOUBLE D Why take just one source of vitamin D when you can take two? Most supplements only contain D3, but Daily Double™ contains both D3 and D2. These critical vitamins not only support skin nutrition, but also heart, bone, tooth, immune, and joint health.
Vitamin D is well known for its ability to help your body properly absorb calcium from food, but it's the vitamin K in Daily Double that controls where that calcium ends up — in your bones and teeth, rather than in soft tissue where it can become a problem.
Magnesium is also included to increase the effectiveness of vitamin D, helping to preserve bone and muscle tissue while strengthening your immune system. Overall, this smart formula promises to help you Unleash Your Potential® all year long.
