## Description

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

Review: What a Steal!...Great Product!...Contains 100% methyl-Folate/Quatrefolic/5-MthF! - Thrilled to find methylated/co-enzyme/active B-Vitamins at such a great price. Methylated B vits. are fully active, your body does not have to 'convert' these in to a usable form - they are already fully absorbable & ready to get to work in your body - - unlike 'old-fashioned'! non-methylated B's (i.e.: B50 complexes & the like) which actually require your body to 'convert' those to a usable form, this process itself is difficult for the body/liver & more so for certain genetic 'mutants'! - Long story short - methylated/activated/co-enzyme B-Vitamins are far superior (my opinion!) & better absorbed than the kind of B-complexes you might find at your local drug-store or Gas Station .... I used to use Jarrow 'B-right' but they changed the formula to contain a mix of synthetic/fake Folic acid & 5-mthf, whereas the Doctors Best brand contains 100% Quatrefolic (5mthf) - so Doctors Best is my preferred choice now! .... I get a definite boost in energy & mental clarity .... I take these every day along side my Amino Acids - the B's ensure that the Aminos can do their job And of course a healthy daily intake of B's is essential for practically every process in the body & to help the Liver keep on humming-along! Two big thumbs up for Doctors Best fully Active B-complex! The product got here (Hawaii) very quickly - 2 days faster than anticipated arrival! desertcart outdoes itself yet again!
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.
