Some people ask: "If I'm already taking a multivitamin do I really need Daily Energy?" Well, Daily Energy Multiple Vitamin ™ is not just any multivitamin. It is a breakthrough in bioactive nutrients that contains all co-enzyme B vitamins and special mineral transporters. We designed this product to enhance cellular uptake of vital nutrients to carry out the instructions of thyroid hormone within cells so that energy is actually made. Take a look at your multiple vitamin. If the form of B12 is called cyanocobalamin, you are getting the low quality form of B12 that actually makes cyanide in the first step of metabolism! Cyanide metabolites are very hard on the thyroid -- only cheap vitamin companies put this low grade B12 in their products. In contrast, Daily Energy Multiple Vitamin ™ contains coenzyme B12 called methylcobalamin and adenosylcobalamin that the body can easily absorb and use for energy. In fact, these are the only type of b-vitamins that are used by people who are fatigued. We strongly recommend trying this supplement out! As part of the Thyroid Energy Package ™ , you should notice a true energy difference usually within the first week of taking the supplements!* Read more about Daily Energy Multiple Vitamin ™ .
