   I started using B Complex from BIOTOPLEVEL about two months ago. My life has changed since I tried this product! My dentist recommended it because she noticed I usually had severe sore throat that were very painful and would last longer than a week. Since she could not determine the exact cause of the sore throats, she knew from her experience using it in other patients that this supplement really works. She was right! I am glad it is working for me as well, and that it combines all the vitamins B1, B6 and B12 that I needed in one bottle and most importantly in a liquid form. Perfect for all people, even for people with malabsorption syndrome.

   If you are used to taking regular Vitamin B12 pills from other brands, you will never go back after trying a good sublingual liquid form, such as this. Suffering from low levels of various vitamins and minerals, some of the downsides of B12 deficiency I have experienced over the years include low energy levels, brain function, irregular metabolism and mood. I have been taking sublingual B12 pills, but I decided to try this liquid formulation since it was the only one available in Amazon that included B1, B6 and B12 all in one product, to see if I got better absorption and results. I couldn’t be happier with this product! Among the many forms of B12 I’ve consumed, only this has produced a “boost” I can feel. Other forms of B12 I took previously helped me function regularly and maintained my energy levels stable, but I feel a “noticeable boost’’ in my energy since I am taking these drops. My brain and body are functioning better and I feel more clear and energetic. The flavor is pleasant, this natural product is definitely a great alternative to other pills or liquids.

   The only negative was the packaging. The boxes which contained the bottles looked like someone tried to open them. Shipping packing looked like someone ran over it. I made sure that the seal was intackt on each bottle to be sure.

   My doctor has prescribed me to take B-12 due to other medications I take that reduces my energy levels. I’ve tried other products in the future in the form of pills but honestly this seems to work better than any other product. When I found it on Amazon, I liked that it not only contains B-12, but also B-1 and B-1. This was the only product in the form of liquid drops on Amazon I saw that contains all of them (B1, B6 and B12). Sublingual application is definitely faster and more effective. I feel this product helped boost my level of energy and strength. I am now a loyal customer of this company.
