Biocidin is a plant-based antimicrobial and biofilm disruptor that’s been used for gut health for over 30 years. Research shows it may help with candida, SIBO, and mold infections without harming beneficial bacteria. Some children may experience detox side effects such as irritability, fatigue, or digestive upset, so it’s best used under medical guidance.
If your doctor has recommended Biocidin, you might be wondering: What exactly does it do? Is it safe for kids with autism? Does it kill good bacteria along with the bad? These are common concerns parents share. In this review, I’ll explain how Biocidin works, what the research shows, the different formulations (liquid, capsule, liposomal), and what parents need to know about potential side effects before deciding if it’s an opt or drop for your child.

Clinical Trial Results on Biocidin
Let’s get into clinical trials of humans using Biocidin. They have lots of different formulas.
Liquid – Uses and Evidence
Biocidin liquid has been shown in clinical trials to have an immune modulatory effect – they can see a 66 percent increase in IgA. The liquid formulation can be used in newborns, all the way up to the elderly, because it can be titrated so easily to increase the dosage. So you start with drops.
Capsules – How They Compare


The capsule version is equivalent to the liquid. They’re red-looking, and one capsule equals five drops.
Liposomal – Strongest Formula & Cautions

A lot of doctors have been recommending this more and more as the preferred formulation. It’s important to understand how these different formulations potentially impact your child.
The liposomal targets the bloodstream and the lymphatic system. It might target the intracellular as well. This is the most potent formula in the sense that it’s gonna penetrate into the body further than any of the other formulations.
Keep in mind that if you’re using the liposomal or if you’ve been recommended to use it, it is quite potent. So it’s definitely something to use under knowledgeable guidance. Out of all their products, this one can cause the most intense die-off. And many times this die-off can happen even after using the liquid or the capsule because the formulation penetrates much differently.
Does Biocidin Kill Good Bacteria?
The company has done before-and-after gut microbiota testing. They don’t see any decrease in beneficial bacteria from using Biocidin. They have seen an increase in akkermansia, a strain of bacteria that strengthens the gut lining and helps prevent inflammation due to a leaky gut.
What Is Biocidin and How Does It Work?
It has a long list, and that might be why your doctor is talking to you about using it. It can cover
- Candida,
- Clostridia,
- Mold,
- Borrelia,
- Giardia,
- SIBO,
- Neuroinflammation.
For neuroinflammation, you usually have to use it much longer, like 6 months or more. Whereas for gut infections, it’s used for a few months.
What Is Biocidin Used For? (Conditions & Benefits)
In my experience of seeing how the top 70 to 100 functional medicine doctors focusing on autism in the U. S. use it, it’s not their most powerful option. It depends on the level of infection.
There are a variety of different ways to test for gut infections, right? And it depends on that list, which one it is. You really want to do a lab test before using this. So you get the lab test back, and if it’s a very strong active infection, normally Biocidin is not going to be used. A lot of times, a prescription will be used. Again, it depends on the actual intensity of the infection.
If there’s a large Candida infection, a prescription will be used first, and then this is typically used as one of their first stopgaps after stopping the prescription. I have seen it used as a first-line therapy when the health concern is more in the milder range.
So let me give an example for Candida. In the organic acid test, let’s say the arabinose level is between 60 and 110, something along those lines. Typically, a prescription is not going to be used when it’s in that range. That’s an active infection. But it’s not a really intense one. So if arabinose is in that range, then something like Biocidin would be used.
Biocidin Side Effects & Die-Off Symptoms
Some children may experience detox or die-off reactions when starting Biocidin. These can show up as anxiety, irritability, fatigue, or digestive upset. The stronger liposomal formula is especially known for causing more intense reactions, since it penetrates deeper into the body. These reactions often come from the breakdown of biofilms and the release of toxins, oxalates, or heavy metals. Starting slowly and using Biocidin under knowledgeable guidance is recommended.
Is Biocidin Safe for Kids?
Biocidin has been around for more than 30 years and is considered safe enough that the liquid version can be used in newborns all the way through adulthood, because the dose can be easily adjusted drop by drop. The capsules and liposomal forms are also widely used, but the liposomal form should be used with caution because of its potency. Overall, Biocidin is safe for children when guided by a knowledgeable practitioner, but monitoring for detox reactions is important.
Does Biocidin Really Work?
Yes, Biocidin has been shown in clinical trials to have immune-modulating effects, including a 66% increase in IgA, which supports gut immunity. It’s been used to target a wide range of infections such as candida, clostridia, mold, Borrelia, Giardia, SIBO, and even neuroinflammation. Doctors typically recommend it for milder infections or as a follow-up after prescription treatments. While not always the strongest first option, Biocidin can be effective when matched to the right type and intensity of infection.
Biocidin Reviews from Parents & Practitioners
From years of observation, many functional medicine doctors include Biocidin in their toolkit for children with autism and gut challenges. It’s not usually the first choice for very severe infections, but for mild-to-moderate issues, it has been seen to do “fantastic things.” Parents report the convenience of the liquid and capsule forms, while the liposomal version is the most potent but also the most likely to trigger detox reactions. Overall, Biocidin is considered an “opt” rather than a drop, though careful use is important.
How to Take Biocidin (Liquid, Capsule, Liposomal)
Typically, the liquid or the capsule would be used first, and then you might switch over to the liposomal. Most parents don’t open the capsule because it doesn’t really taste too good. And as it’s red, it’s sometimes hard to mask.
There is that liquid formulation, so you could certainly use that if your child isn’t swallowing pills.
The liposomal is in a pump form, and you want to take it on an empty stomach if possible. I know it gets really hard to schedule these different kinds of supplements when they have to be on an empty stomach. But you want this to be on an empty stomach as much as possible. You squirt it under the tongue. The child holds it for about 30 seconds. And that way, the Biocidin gets into your bloodstream.
Trying Out the Liposomal Biocidin (Taste & Parent Experience)
I’m a little nervous as to what it’s gonna taste like. Oh, there’s a child lock on it.
It tastes a little like pine needles. I don’t know why. It’s not overly gross. But I can’t say it’s fabulous.
It’s amazing how this liposomal formulation is being absorbed. There really wasn’t much to swallow. So I don’t think your child would need to even hold it for 30 seconds. Whoo! It certainly does its job and gets into the bloodstream. You’re not really concerned too much about having to swallow it. It’s pretty cool, the way it does that. The taste is not terrible, but I wouldn’t say it’s fabulous.
Final Verdict – Is Biocidin an Opt or Drop?
Biocidin! Depends on the formulation, but Biocidin is definitely an opt. I have seen it do fantastic things for a variety of different infections and health concerns. It’s certainly potent. You do want to be mindful of detox reactions.
