I few days ago I started CoQ10 to try to help with the PN, 100 mg twice per day, Jarrow in a liquid capsule. Since about then I have been having stomach & chest pains, sometimes feels like acid reflux. I have read upper abdominal pain may be a side effect. What dose are people taking and have you had any side effect like this? The reason I'm not real sure it's from the CoQ10 is that I eat very healthy in general but when I splurge on a lot of fat or something I have stomach pain.

Are you taking it with food? That may help.

I started d-ribose, almost two weeks ago, and for a simple sugar, it made me really nauseous! I HAVE to take it with food or else. I also had heartburn at first too, but both effects are now gone.

Some people have complained about CoQ-10 here. But on PD forum here where they take massive doses of it I rarely see complaints.

Try starting with once a day, and with food and see if that is better.

Which one on this page is it?
http://www.iherb.com/Search?kw=Jarrow+CoQ-10

Is it the mixture one, with the other ingredients in it?

Yes it has a few other things in it: Jarrow Formulas, Q-absorb Co-Q10 Plus, 100 mg, 60 Softgels

What is PD? I don't only have these symptoms right after I take it, I'm having them thru much of the day. I do take it with food in the AM but not the PM.

If I were to have an unknown gluten insensitivity, could stomach pain like this be triggered by eating a lot of bread from a local bakery? This was two days ago. If I could only be so lucky to find a cause for the PN.

Everyone with chronic PN should consider gluten at one point.
It is a huge cause of neuro problems.

Some of our older members have moved on, but Gluten has been identified in some posters here in the past.
We have a gluten forum:

Considering this possible trigger, takes some patience and willingness to read and learn. Then doing the diet requires some motivation as well. But the payoff can be huge, for those who succeed.

The Parkinson's forum (PD) uses massive doses of CoQ-10 and stomach upset doesn't appear there often.

Your product has other things in it. One of them may be upsetting you too. That is why trying supplements should be one at a time ideally, and mixing other factors, confuses more than helps sometimes.
