BioActive B12 (1000 mcg) Liquid: Vitamin B12 Plus L-Methylfolate
My primary MD recommended this because a different sublingual drops brand wasn't working for me, I felt no change from the other brand. This Triquetra alongwith another supplement are definitely helping me heal from adrenal insufficiency, I see it in my lab results and feel it in my body!
I Love all of your products but the taste of this B-12 is not my favorite. It leaves a bad aftertaste too. However, I feel it works really well.
I love all the Triquetra products.
Triquetra continues to email me, asking for a review of B12 liquid drops I purchased less than 1 month ago. I cannot review on the effectiveness until my next bloodwork in March 2025, at which time I planned to make an honest review. I will say, the appearance of the liquid is somewhat lumpy and adheres to the inside of the bottle, which is why I follow the instructions to shake well before each use. The taste is fine. Not bad at all. At 1st I was taking way too many drops. Once I realized my error, I corrected my dose and want to remind everyone to be diligent regarding your dosage. It is vary easy to take too much of any liquid drops. 4 drops in the dropper is actually a VERY small amount in the dropper. Based on thorough review of available brands, I purchased 2 bottles of this vitamin B12 directly from Triquetra. I remain confidently hopeful that my lab report, after 6 months of use is very favorable, at which time I will gladly raise my review from 4 stars to 5.
