Hey all
I joined this community months ago because I saw other people were taking thiamine like I was however I was not taking it for Parkinsons but for a long time unknown illness I think is genetic. Anyway after more reading thinking etc I am now trying biotin, and feeling better after a few days on it, and if you look at the symptoms of biotin genetic diseases- biotinidase is the main one- some of the symptoms match Parkinsons, and on review websites for biotin like here bulksupplements.com/pure-bi... or amazon people take it for MS, ALS, and some of the symptoms they report improvement of are a lot like Parkinsons so it might be helpful for that also.
in a patent on ALS, and MS they use up to 700mg a day
To treat biotin genetic diseases they use up to 1,000mg a day but usually between 5, and 300mg.
The LD50- the amount that kills 50% of the organisms it is given to- in rats is more than 10g/kg which is higher than alcohol, and table salt so biotin is very safe.
Tablets are sold as 5mg (5,000 mcg) , 10mg (10,000 mcg) , or on amazon they have 100mg (100,000 mcg) ones.
Or several places sell the raw powder.
It is helpful for hair, nails, and skin too.
Richest food source is bakers/brewers yeast with 200mcg per 100g.
I have been on 300mg a day for 5 days now with zero side effects. Great stuff.
Good luck all.
