Great way to start the day!
I've been using Isotonic for just under 3 months and for me this it is the first thing I do to get my day started. It does provide a good natural, non jittery pick me up in the first few hours of the day. The flavor is a bit tart or sour at first but quickly becomes sweet, and after a few weeks you won't even notice how tart it once was. I will absolutely keep taking this B12 supplement and recommend it to everyone!

If you don’t like swallowing pills…
Hard to tell how well a vitamin works. Since I don’t like swallowing large pills and capsules, came back to this brand for ease in swallowing. No problem with taste. Have mixed a couple different vitamins together to take at once. Only good vitamin is one that you take

My thinning hair grew thicker
A good 20+ years ago, I experienced stress related hair loss. Dr told me it was female pattern baldness! I tried numerous shampoos (FAIL) and eventually this product. Miraculously my hair re-thickened. Many years later, I had a surgery that causes me to not metabolize nutrients well. My hair had thinned badly when I remembered this Isotonix product. I happily report that once again it has reversed my hair loss. Is it complete restoration?? NO! I’m in my 70s now and women usually experience thinning hair. But no one would now guess😊. Sometimes those routine blood tests don’t tell the whole story AND doctors can dump a scary DX on you without any due diligence.

Very sugary , they changed formula
I’ve been using this product for more than 10 years and this time it seems that they changed the formula, firstly the bottle felt heavier and when I pour the powder it seemed that it was just sugar, which I’ve never noticed that, it only taste like sugar you can even see the granules in it, I’m very disappointed that they changed the formula.
