“The supplement is a stable product that stores reliably with no visible deterioration. A little more information is needed to describe it's chemical stability in water (cooking liquids) at boiling point other than that the tablets do crumble after a minute or two in the mouth. I am taking the supplement because I am 71 years old with tremors and a MRI scan showing severe small vessel disease. I am a pathology laboratory scientist with enough curiosity. Atypical Parkinson's Disease is not ruled out but a dopamine trial showed only a 20 - 25 improvement in symptoms. More investigation is indicated.”
