If you have looked at the ingredients in FRS Healthy Energy, whether it be the FRS liquid concentrate, FRS cans, or even the FRS powder, you’ll see it contains caffeine. If that concerns you, read this…

Dear Levi,

Thank you kindly for the reviews of energy drinks, specifically the FRS Healthy Energy one, but I have one concern. I have high blood pressure so I have to greatly limit my salt intake and avoid caffeine. FRS contains caffeine. Can I still drink FRS if I have high blood pressure?

Hi Dorothy,

Thanks for the question, because the caffeine was also one of my concerns when I first read the FRS ingredients. I was kind of disappointed that FRS needed to include extra caffeine, as I’ve seen plenty of people get jittery and bounce off the walls after consuming one or two typical energy drinks, which are usually LOADED with caffeine and other stimulants.

However, someone with high blood pressure could experience worse affects than feeling jittery!

According to the Mayo Clinic, various studies have shown a link between caffeine intake and high blood pressure. The results differ, but they usually lead to the recommendation that you limit your caffeine intake to no more than two cups of coffee per day.

The good news, then, is that a serving of FRS contains much less caffeine than that. FRS chews are equivalent to 1/4 cup of coffee, FRS liquid concentrate and powder are equivalent to 1/3 cup of coffee, and the FRS cans are equivalent to 1/2 cup of coffee.

So you could probably have a serving of FRS each day, along with a cup of green tea, and you’d still have consumed less caffeine than if you had a single cup of coffee. If you have high blood pressure it might be better to consume no caffeine at all, but FRS and/or green tea would be a suitable replacement if you already drink coffee.

I just wouldn’t do coffee and FRS on the same day.

Remember though, I am not a doctor, nor do I play one on this website! My best recommendation is to print out a brochure from the FRS website and take it to your doctor, who can make a recommendation based on your unique situation. This is even more important if you are on any medications!

  1. Hi Levi,

    I like your website. It has some interesting articles. I read the one about the exercise ball. I think I am going to get one this weekend.

    I also read the article on healthy pizza toppings. I like all of them except the onions. I like a little bit of onion, but I have never acquired a taste for onions.

    Thank you for letting me share…

  2. Hi Levi,
    I have used FRS and found it to be very useful in terms of increasing my energy levels and mental focus. However, my father (who is in his seventies)has had an Angina problem for a while and after a gastroenteritis infection is rather weak. Is it OK to give him FRS to increase his energy levels?

  3. Hi Suman,

    With any heart condition it could be problematic to have stimulants like caffeine, but as I mentioned, FRS is pretty low in caffeine and looks like it has healthy ingredients otherwise.

    I would think anyone who can drink green tea can handle FRS, because the caffeine content in each one is pretty close. But again, that’s just my opinion, and definitely not medical advice!

  4. There’s NOTHING healthy about FRS. Do you really believe that ‘organic cane juice’ is -healthy-? It’s not. Nor is any sweet juice. Run a marathon right after you drink it, and you MIGHT undo most of the negative effects, but is that really what you’re gonna do? This is gonna do the same thing to your liver that alcohol does, without the high. No thanks.

    The question had to do with FRS as it relates to caffeine and high blood pressure. It wasn’t a debate about the health benefits or lack thereof of FRS.

    Also, this is a site for endurance athletes like marathon runners, which means that people here might just be using FRS during marathon training!

    Can someone with Celiac Sprue/Disease drink FRS?

    People with CS/CD cannot consume wheat, rye, or barley due to the gluten in these grains.

    I see that FRS has inulin in it, which some sources say contains a wheat derivative.

    According to the FRS site, nothing in FRS contains gluten.

    As for the inulin. I’ve never heard of inulin containing a wheat derivative, but even if it did, I doubt that would still have any of the gluten in it.
