research the FMT
therapy, it has helped some people with Parkinsons.
Also Liver Flushing
can be helpful.
And generally natural and healthy Diet
free from industrially processed foods and drinks.
About 10 g of vit C
I personally believe in whole foods and in unprocessed nutrients.
Consuming anything processed by food industry increases the risk of problems, as profit is always more important than quality.
I believe we should get as much vit C as we can get by eating natural fruits and vegetables.
I believe we should get as much vit C as it was available to our ancestors. Stone age. Paleo diet.
I doubt you can overdose on vit C by eating whole foods like berries, fruits, herbs or vegetables.
The most important rule in healthy Diet
Too much can be as bad as too little.
Of just about anything!
Even too much of oxygen or too much of water is not good.
Ballance is the road to health, extremism right or left sooner or later brings problems.
Just my opinion.
