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.

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.

Quick Absorption, High Potency
These methylated B vitamans come in an easy to swallow capsule. They are dosed to give fast acting energy I need to get through the day. I have purchased mutlitple bottles and have experienced the same consistent high quality each time.

Watch out for the niacin flush
The niacin will flush the heck out of you about 20 mins after you take it. I thought I was having a heart attack at first until I realized that it was happening every time I took my B complex
