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.

A must for hair loss.
I purchased this for my mom's hair loss. After one week of taking it, her hair has been falling out less.

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!

Methylating B complex that works
If you have a a defective MTHFR gene or suspect so give the product a try. You will see a positive difference. If you cannot methylate folic acid folate or cyancobalamin, Welcome. To your new world.

Excellent B Vitamins
After reading the reviews some people are claiming to have a bad reaction to theses B- vitamins and that they cannot take these any longer. This is a Niacin flush and is a good side effect of taking the right niacin. Vitamin B3 or niacin is a vitamin that doctors will often prescribe to decrease your cholesterol. The vitamin B-3 in these vitamins will often cause the flushing that will cause skin redness with a burning, prickly sensation. This is harmless and is actually very good for your body. This flush increases micro circulation. Look up the health benefits of micro circulation.
