Is V8 really safe? I decided to make my own V8. One of the 8 ingredients is watercress. I google watercress to get a photo so when I return overseas I can find it. The wiki website mentions the follow drug interactions with the CYP450 family-the same family of drugs we all take. I personally am sensitive (used to frequently faint when taking flecainide and Prilosec together) due to its inhibitors. I still take low sodium V8 with my drugs when my heart is jumpy with PVCs. By inhibiting the cytochrome P450 enzyme CYP2E1, compounds in watercress may alter drug metabolism in individuals on certain medications such as chlorzoxazone.[15] https://www.afibbers.org/forum/read.php?9,199621,199621#msg-199621 Sun, 20 Sep 2026 13:03:51 +0000 Phorum 5.2.23 https://www.afibbers.org/forum/read.php?9,199621,199628#msg-199628 Re: Is V8 really safe? https://www.afibbers.org/forum/read.php?9,199621,199628#msg-199628 Carey AFIBBERS FORUM Sat, 07 Jun 2025 02:48:41 +0000 https://www.afibbers.org/forum/read.php?9,199621,199627#msg-199627 Re: Is V8 really safe? https://www.afibbers.org/forum/read.php?9,199621,199627#msg-199627

The trouble is I don't know if Campbell's is saying the 850 mg is elemental K or if it's really just 850 mg of KCl. One mg of KCl does not equal one mg of K. I can calculate it for you if you can figure out what they're actually reporting on the label.

In the nutrition facts label, they are talking about 850 mg of K, not KCl (or on this label, 830 mg). I remember this from back in the day when I used to use it.]]> GeorgeN AFIBBERS FORUM Sat, 07 Jun 2025 00:42:01 +0000 https://www.afibbers.org/forum/read.php?9,199621,199626#msg-199626 Re: Is V8 really safe? https://www.afibbers.org/forum/read.php?9,199621,199626#msg-199626
How much to add is another question. Campbell's adds a little over 100 mg K per ounce of juice (850 mg per 8 oz of juice), so I would go by that. The trouble is I don't know if Campbell's is saying the 850 mg is elemental K or if it's really just 850 mg of KCl. One mg of KCl does not equal one mg of K.

I used to travel with a container of potassium chloride powder. I soon learned to put the container out by itself, not hidden in my luggage for TSA go find. It seems there is something in KCl that triggers their sensors.

KCl is slightly radioactive. I'm sure that's what they're picking up.]]> Carey AFIBBERS FORUM Fri, 06 Jun 2025 23:50:37 +0000 https://www.afibbers.org/forum/read.php?9,199621,199624#msg-199624 Re: Is V8 really safe? https://www.afibbers.org/forum/read.php?9,199621,199624#msg-199624
Until I switched to potassium citrate, I used to travel with a container of potassium chloride powder. I soon learned to put the container out by itself, not hidden in my luggage for TSA go find. It seems there is something in KCl that triggers their sensors. Once they scanned the container, they said my quantity was OK, but if I'd been carrying more, it wouldn't have. My container was about the size of a salt shaker you'd get at the grocery store.]]> GeorgeN AFIBBERS FORUM Fri, 06 Jun 2025 21:15:54 +0000 https://www.afibbers.org/forum/read.php?9,199621,199623#msg-199623 Re: Is V8 really safe? https://www.afibbers.org/forum/read.php?9,199621,199623#msg-199623 kliving AFIBBERS FORUM Fri, 06 Jun 2025 21:09:53 +0000 https://www.afibbers.org/forum/read.php?9,199621,199621#msg-199621 Is V8 really safe? https://www.afibbers.org/forum/read.php?9,199621,199621#msg-199621
