Andy,
I'm also taking it, but am doing so for its anti-inflamatory properties, rather than to improve my physical disabilities (I'm too far gone but obvs any plus would be a huge Brucie Bonus !!!!) I have noticed a reduction in the frequency I now need to take Ibuprofen for pain - which is very welcome indeed.
I believe Dr Bedlack recommends taking 2 capsules every day for the 6 months - you may want to check.
Best of luck.
Love Ellie.
