Helps support energy production and cell metabolism!

Doctor’s Best Fully Active B Complex provides energy and helps coping with stress. B vitamins are needed to make energy from foods‚ and to make and maintain DNA‚ genes‚ cells‚ tissues‚ organs‚ and enzyme functions. B vitamins are fundamental to life‚ and humans cannot make them‚ therefore we need to get them through the diet. Doctor’s Best Fully Active B Complex provides only the best-utilized B vitamin forms. This includes fully active folate‚ the body’s most fully active folate and MTHF (methyl-tetra-hydro-folate). The Fully Active B Complex also provides fully active vitamin B12 as methylcobalamin (methyl-B12) to help ensure excellent oral absorption.

      I took this product for years and it worked great for me. Gave me more energy during the day.

      Pros

      Works well.

      Cons

      I stopped taking this product once I became aware of fillers and binders. Since I take handfuls of tablets every day, the bad fillers and binders started to add up. I now attempt to choose products without filler and binders. This one has magnesium stearate and silicon dioxide.
      I would recommend this item to a friend.

      When I first took this I gave it a bad review. The first day, the niacin made me feel sunburnt but the next day and since, it’s been fine. I like that it’s methylated so easy to absorb. If you have the MTHFR gene this is a good b complex for you.

      Pros

      Everything

      Cons

      Nothing

      Tried a lot b complex and individual b's over the years mainly to help with energy but nothing compares to this Best Fully Active B Complex by Doctor's Best. No strange or off feelings when taking it either-like most synthetic vitamins and mineral supplements! The activated forms are really the only way to go with b vitamins. Only downside perhaps is overloaded with b-12. Only take a few times per week because of that.

      Pros

      Activated forms

      Cons

      Too much B-12
      I would recommend this item to a friend.

      from Rollinsford, NH on 5/15/2017
      Best Fully Active B Complex by Doctor's Best is a new item for me. I was using the fully active B12, but had to decrease the amount I was using as my blood levels were on the toxic side. I will be using this for a month, get new bloodwork done and can provide an update then. It's a good idea to check with your doctor first before taking supplements.

      Pros

      Increase energy level, helps with nerve pain.

      Cons

      None

      I take Best Fully Active B Complex by Doctor's Best daily for the little energy boost it gives me and this product is high quality as it contains the better form of B12 (methylcobalamin) and the better form of folate (Quatrefolic) both absorb better. The Quatrefolic can also aid in depression and digestive issues which it has for me. I was taking a more expensive brand of B Complex because it included these better ingredients but was so happy to find the Doctor's Best at better price which makes it possible for me to afford to take it daily without interruption.

      Pros

      Higher quality ingredients at reasonable price.

      Cons

      I would recommend this item to a friend.
