## Description

Doctor's Best Fully Active B Complex provides energy and helps coping with stress.

Review: Very good w/o negative side effects - As a plant based eater, I have taken a vegan B12 supplement for years. Recently, I ran out and was “too busy” to order more. After a couple months, I noticed having low energy especially in the afternoons and then started having heart palpitations. I went to the doctor to be safe, and confirmed that everything was good except my B12 was on the bottom end of the “normal range.” I ordered this B complex, and within less than 2 weeks of taking it daily, the palpitations were gone and energy is coming back. Lesson learned. This is a great oral supplement and seems to be very effective without any negative side effects.
Review: Best B complex - I have tried many others and this complex is not only the most complete but it's a great value. B vitamins are so essential for good health and help with energy. I take mine mid -day with a snack to give me an energy boost. It's better than any energy drink! My hair has also grown in better with less Grey. Overall, if you are looking for a good quality B complex, I definitely recommend this!
