Going to Dom. Rep. Therefore to avoid complications at the airport just ordered mp and thiamine in capsules which I normally use in powder form. It'll also give me a break from the powders. Thank you all for your continued input on this forum for you all make life with PD a but more simple. I bought the high potency B1 because it doesn't contain gelatin, it's on sale and it has added magnesium which is essential for absorption. The MP I bought is the Barlow's 40%.
