(female 53yrs caucasian) After a blood test I learned that my B12 was 143. My blood was tested 2 months later and it was up to 687, then one year later my blood tested to 1389. I take one a day, and I feel much better than I did a year ago. My energy has improved, as has my level of "happy". They are easy to take as they sit under the tongue and dissolve. The bottle comes sealed. The quality is good, -- delicious if you like cherry. If your doctor recommended that you take B12 I recommend this product to those with looking to increase their B12.
My husband finds tablets hard to take and hard to swallow, so these were a perfect solution! Great quality, great ingredients, great taste. Cherry flavoured but not overbearing. This was helpful for getting enough folic acid and the B12 helped with energy, especially those afternoon slumps! I recommend this product and would purchase again.
That was one of best supplements , I finished the bottle and purchased again after 30days break in between, therfore its 100% safe to use The best product to use is sweeteners free , even I prefer not to have the one contained Sorbitol the supplement promote healthy nerves function and taste okay if you prefer to chew it
