Amazing product!

Amy DeasonOctober 30, 2025

My husband was constantly on blood pressure medicine with persistent leg swelling and all over not feeling good. But a friend told me about these and we decided to try them. So glad we did! These helped drop his blood pressure and decreased the leg swelling immensely. It is very effective, inexpensive, easy to use, and lasts a long time. Read more

Excellent product

MVSeptember 28, 2025

I am a studying herbalist and this stuff is amazing! Keeps me and my son healthy and I am ALWAYS recommending it. As an ounce of prevention, during cold/flu season we take it 2x per week (i.e. Sunday & Wednesday). My son’s sick days at school were almost zero and consequently mine too. If you catch something, use daily with other methods and herbs/meds to assist (Ridgecrest Herbals, Clear Lungs and Clear Sinus)…(Elderberry items and Emergen-C). Read more

It really, really, REALLY works (unsolicited review).

DBJanuary 5, 2017

My hubby was skeptical, since EmergenCee (sp?) did nothing for us. But Defense Plus works GREAT!!! Since it's an adaptogen you shouldn't use it every day all the time or it will lose its effectiveness, so just use it for a week or 2 when needed. But if you're getting sick or your coworkers or kids are sick you will have a very good chance of *NOT* getting sick. (We also take it b4 and while we travel on planes.) My husband works a week per month on a boat in close quarters with other guys who are often sick. I'd say about 95% of the time he can avoid getting sick by taking Defense Plus once a day (NOTE: More is not better, just take once a day.) Honestly, many times, when we felt "that feeling" (where we knew we were getting sick) we took this and voila!!! We didn't get sick, it just went away. No lie! This is *not a solicited review,* I am just a HUGE fan of this stuff (have been for years) and its ingredients. No stomach upset or side effects. One problem: You have to **remember to take it** when others are sick. That's a habit you just have to develop. Really, try it, you will be amazed. (And no, I don't work for the company.) Read more

Very Effective Natural Antibiotic...

John ThomasDecember 27, 2012

I have been buying this Nutribiotic formula locally for quite some time now. But recently the place where I usually get it stopped carrying it, so I am happy to find that its available here on Amazon... I always have some in the house for when I feel something like a bad cold, flu, cough, or just feeling crappy may be coming on. And more importantly, I have even relied on it when I feel that I am genuinely fighting a true infection, like a sinus or chest infection. And all I can say is that in most cases it's been amazingly effective for me. I always hated the fact that the majority of visits I have made to my doctor or treatment center has been for some infection, knowing full well all it will take is an antibiotic to clear it up. Especially sinus infections that just about all of us have had in the past. No matter how many I seem to get, or how well he knows me now, my own doctor always insists on "seeing me" so he can continue to dine regularly on lobster and cracked crab. I admit that I was skeptical of this stuff at first considering that all antibiotics are only available through prescription. But I also figured that I really had nothing to lose. (You can always crawl back to your doctor and beg forgiveness.) Fortunately it wasn't long before I became a believer. I not only feel that I have in the past both cured and cleared up various infections, but just like when on prescription meds, whatever I have seems to start easing up and I start feeling better in just 48 hrs or so. And one thing that one should keep in mind with something natural like this is how you really can't build up a resistance to it as easily as a prescribed antibiotic. But with that being said, just like prescription meds, I strongly suggest that you only take this supplement on the onset of feeling something coming on, or shortly after feeling sick, and then for no more than 10 days after you start feeling better. I have abided by this rule and swear I have saved hundreds of dollars and valuable time not making my doctor richer... In conclusion, as much as I believe this is a very safe and effective product, I feel I should advise anyone considering this that certainly not is this natural formula a miracle drug, or something to be messed with if you are seriously ill with a virulent infection. If you have something like a very high fever or are vomiting blood, forget this stuff and get to your doctor fast. But in other cases where we are experiencing something very common to us or well known, I honestly believe this Nutrbiotic is very safe, effective, and well worth a try. It's proven itself to me several times over and I highly recommend it... : ) Read more

Keeping your immune system up.

R M ThompsonMarch 27, 2025

During the winter months in Montana, I wouldn't be without these. Whenever I feel a chill or cold coming, I take one these and I'm fine the next morning. They keep my immune system up. I always have at least one in my medicine cabinet. Read more

I like anything that's a natural approach to medicine and this ...

Angela TeraoJune 14, 2015

For the past couple of years I always felt slightly sick, almost as if my immune system just wasn't working. I was originally looking for an alternative for antibiotics for my skin, but then I stumbled on these pills. I like anything that's a natural approach to medicine and this had promising reviews. I take one or two a day, depending on how I feel- one in the morning, and one before I go to sleep. I DO feel better, and I didn't get sick at all after I started taking these. However, I have a really sensitive stomach, and I don't know, I think it doesn't sit too well with my stomach. Sometimes I feel super bloated after I take the pill but maybe it's because I take it on an empty stomach in the morning. And I've noticed that sometimes if I concentrate too much on the bloatness I feel like I'm gonna throw up. But it does what its supposed to. So four stars. Read more
