Excellent! I find the MethylCobalamin significantly reduces my anxiety levels and assists to boost my energy. Dissolved under my tongue, it has a pleasant flavour. the package is convenient . This is the best quality sublingual B12 product I have tried. I like the flavour and how I feel after taking one tablet.
I have been using this brand for years and have my B-12 level checked annually. It is always very high. I trust this brand. I purchase all of my vitamins and supplements from iherb because they give the expiration date of the product you will receive. I herb has quick delivery and well packaged. Thank you!!!
