Thank you Summer Myrick for recommending this product to me! I've been using it for a week now and I feel like I have more energy as well as a better mental state. You're so knowledgeable and knew exactly what my body needed - thank you!
B-12 was recommended by my doctor to help with my neuropathy. I saw a slight improvement with this product.
I tried using this instead of my normal caffeine intake. I feel so much better!
I finished one bottle and did not immediately reorder, so it was a few months before I started taking it again. I believe Active-B12 really helps me have more energy and a feeling of well-being. It is a little tricky learning how to put drops under the tongue, but easy after a little practice. It tastes like black cherries to me. My experience with this product has been all positive.
