It can take up to a year or more to recover after a single round of an antibiotic!!
Giving an antibiotic shouldn’t be taken lightly, but sometimes they are needed. And there ARE things you can do to mitigate side effects and protect/rebuild the gut.
Saccharomyces boulardii: for gut support
The first thing you want to get is a Saccharomyces boulardii probiotic. This is a probiotic yeast (not a bacterium), which allows it to survive antibiotic treatment and prevent antibiotic-assocaited diarrhea, gut dysbiosis, and C. diff. It helps protect the gut microbiota and supports immune function.
You can get Florastor on Amazon or at any drug store/pharmacy/grocery store.
HOW TO TAKE:
Take 1 packet twice a day, taken 2 hours away from antibiotic for the full course of the antibiotic. For me, doing 2 hours after taking the antibiotic is easiest to remember. If I have Florastor left after the antibiotic course, I finish it and then switch back to my normal probiotic. But you could continue with the Florastor for another pack, if you wanted. If you don’t already take a probiotioc daily, you should be on one at least 6-8 weeks after an antibiotic.
Scutellaria baicalensis: for antibiotic effectiveness
Scutellaria baicalensis (Chinese skullcap) contains active compounds baicalin and baicalein that have shown the ability in lab studies to enhance the effectiveness of certain antibiotics.
Research suggests these compounds may help restore antibiotic sensitivity in some resistant bacterial strains, meaning they can make bacteria more susceptible to treatment when used alongside conventional antibiotics and combat against antibiotic resistance.
HOW TO TAKE
20 pounds 2-5 drops 3x per day
30 pounds 2-6 drops 3x per day
50 pounds 5-10 drops 3x per day
100 pounds 10-25 3x per day
100+ pounds 30 drops 3x per day
3x/day ideal
It doesn’t matter when you take it, but take it during the full course of the antibiotic and 6-8 weeks after.
Very gentle. Can put a drop on the nipple for breast-feeding baby, or a drop directly in the mouth. Mom can also take while breast-feeding for baby to get the benefit that way, too, in addition to putting in the mouth.
Black Walnut: for biofilm busting + gut lining integrity
*not pregnancy or breast-feeding safe
Biofilms are protective communities that bacteria and fungi build around themselves that allow them to hide from the immune system and making them harder for treatments to reach. Because microbes inside biofilms are more resilient, they can lead to to lingering or recurrent infections.
Black walnut (Juglans nigra) contains antimicrobial and biofilm-busting properties. Lab research has shown activity against certain microbes, and it’s often used to help weaken protective barriers that allow bacteria and fungi to persist. It also helps promote gut health by fostering a balanced microbiome, reducing inflammation, and acting as a natural antimicrobial to help eliminate harmful bacteria.
HOW TO TAKE
20 pounds 2-5 drops 3x per day
30 pounds 2-6 drops 3x per day
50 pounds 5-10 drops 3x per day
100 pounds 10-25 3x per day
100+ pounds 30 drops 3x per day
3x/day ideal
It doesn’t matter when you take it, but take it during the full course of the antibiotic and 6-8 weeks after.
Scutellaria baicalensis: can also be used as a biofilm buster
In practice, Dr. Noah Lebowitz (founder of Supreme Nutrition) and Dr. Charlie Fagenholz prefer Black Walnut as a biofilm buster, and have found it muscle tests best in their patients. However, Scutellaria baicalensis “technically” has more extensive, documented efficacy. So, if budget is tight and you need to simplify, you can give Scutellaria baicalensis a try since you’ll already have it on hand.
Antifungal of choice: for preventing yeast overgrowth
Antibiotics can lead to yeast overgrowth because they kill off the beneficial bacteria that normally keep fungi like Candida in check. When those protective bacteria are disrupted, yeast has less competition for space and nutrients and can multiply more easily, especially in the gut, mouth, or vaginal microbiome. This imbalance is why some people develop thrush, yeast infections, or digestive symptoms during or after antibiotic use.
Scutellaria Baicalensis: safe for any age, very gentle, breastfeeding safe, pregnancy safe
Oil of Oregano (2yr+) and Garlic: I would just start with Scutellaria since you’ll already have it on hand. Then if you find you need something stronger, or if you’re prone to candida, consider these.
You can also just eat raw garlic. For an adult, I would do 1 clove 3x/day (3 cloves total) for the course of the antibiotic. For a child, use your best judgement, but 1-2 cloves a day should be fine during the course. Either way you can then switch to something more gentle like Scutellaria for 6-8 weeks following.
Whole Food Considerations
Fermented Foods: Fermented foods like sauerkraut, kimchi, plain yogurt, and kefir are another great way to get additional probiotic benefits. Fermented foods contain live microbes that help replenish good bacteria, support the gut lining, reduce antibiotic associated diarrhea, and lower the risk of yeast overgrowth. Eating them during treatment can help maintain balance, and continuing afterwards helps rebuild the microbiome.
High Protein Foods: High protein foods are helpful during and after antibiotics because they provide essential amino acids (glutamine) that the body needs to repair tissues and rebuild the gut lining. Amino acids help make enzymes, antibodies, and structural proteins like collagen that aid in healing. Meat, seafood, eggs, and dairy are the best sources since they are a complete protein, meaning they contain all essential amino acids in forms that the body can easily absorb. Be careful with processed dairy, as it can be inflammatory. Plant sources include: quinoa, soy foods, buckwheat, hemp seeds, and chia seeds.
Bone Broth: Bone broth provides easily absorbed amino acids like glycine, proline, and glutamine that help repair the gut lining and aid in tissue healing. It also contains collagen compounds and minerals that nourish the digestive tract and be gentle to consume when appetite is low during/after antibiotics, or when digestion is sensitive.
Prebiotic Foods: Prebiotic foods help probiotics work better because they act as fuel for beneficial gut bacteria. They’re types of fiber and plant compounds that humans don’t fully digest but gut microbes do, which helps those good bacteria grow, produce beneficial compounds, and rebalance the microbiome during and after antibiotics. Prebiotics are naturally found in foods like garlic, onions, bananas, asparagus, oats, and apples, or can be taken as supplements.
Raw or manuka honey, cod liver oil, and whole-food vitamin C sources like acerola cherry or camu camu can support the body during and after antibiotics by helping regulate immune function and inflammation during recovery. Honey provides natural antimicrobial compounds and soothing support for mucosal tissues. Cod liver oil supplies vitamins A and D plus omega-3s for immune balance and tissue repair. Whole-food vitamin C supports antioxidant defenses and healing. You can choose to do all three daily, rotate them regularly, or simply pick and choose based on what works best for you.
This is not a free pass to take antibiotics willy-nilly. Antibiotics should only be used when truly necessary. Even with supportive measures, they can disrupt the gut microbiome and immune balance, and overuse contributes to antibiotic resistance. Taking them “just in case” can do more harm than good.
