Is this still relevant? Some other info says caffeine reduce vitamin B1?

[TL500]

I haven't read all of this. But just wondering if black tea and green tea can help PD, and on the other hand can cause vitamin b1 deficiency (?) because it has caffeine, what would be the verdict? Any idea? Thanks

"Does caffeine reduce thiamine?

Heavy consumption of tannin-containing or food rich in caffeine, theobromine, and theophylline (such as those present in coffee, chocolate, and tea, respectively) can inactivate thiamine, thereby compromising the thiamine status (7, 14, 15)."

Thanks , and sorry I forgot to attach the link, which I have just done now.

so not sure what the solution is on this - maybe take more thiamine? I looked up decaf green tea and supposedly it has less in the way of benefits

"Decaf Green Tea is good for you only if you consume the entire tea leaf. Common sense about decaf green tea: Decaffeination reduces the antioxidants, so if you drink the decaffeinated green tea you will need to drink more green tea to get the same health benefits as regular green tea."

I would guess that a typical b complex pill everyday might just more than compensate for any loss created by diet items, except coffee, and I don't know where I picked up the bit about coffee. Maybe somebody knows for sure.

"Does Green Tea Contain Caffeine? Just like black, white and Oolong tea, green tea contains naturally occurring caffeine. Although the levels of caffeine in green tea are slightly lower than you'd expect to find in black tea, and considerably less than in a cup of coffee."

I can't remember the specifics but I recall Dr Costantini's saying not to take your B1 with coffee. Maybe he said not to take your B1 near the coffee. My husband takes half his B1 on awakening and half around 3pm. He drinks coffee after breakfast.

[TL500 in reply to ForViolet]

My understanding is not only not take B1 near the coffee, but not taking it at all as it depletes B1, and we need to take high dose b1 to treat PD. Am I right?7

[ForViolet in reply to TL500]

I don't remember that Dr C said to never drink coffee while doing B1 therapy. Just to take B1 away from coffee. That's what we're doing. You could check Dr Costantini's website, but that's what I remember. I'm sure there are many theories, but I'm going with Dr C since I think coffee and tea important for HwP.
