How Antibiotic Antidote® Works

Section Image

If you need to take antibiotics, we want you to know you don’t need to accept what it does to your body afterwards. When antibiotics are taken, not only do they kill the pathogens causing our illness, but they also destroy the good bacteria we need for optimal health. Gastrointestinal upset, skin irritation, and compromised brain function are some affects you can expect from taking antibiotics. Antibiotic Antidote® helps reclaim the normal balance of bacteria in the gut and promotes better immune health.

Antibiotics destroy or slow down bacterial growth and leave the immune system compromised. While the process of gut restoration can take several months to re-establish itself, taking our unique probiotic is an easy way to support your immune system and your journey to better health.

Our eight-strain formula includes three keystone strains that are proprietary to us and work in harmony with the other four strains to form a stable, sustainable community that allows the gut microbiome to produce the necessary metabolites to promote healthy living. We also include a versatile bacterium that comes from the soil. Our ancestors encountered soil every day. Our modern lifestyles have taken us far away from the many beneficial microbes that are found in soil.

Antibiotic Antidote® creates the right environment to enable friendly bacteria to flourish again as your body rebuilds its ecosystem and you begin to feel better.

Take 1 capsule per day. Antibiotic Antidote can be taken during your course of antibiotics, at least two hours separate from your antibiotic dose, or after you finish your course of antibiotics.

Bacillus subtilis (DE111®by Deerland ):

  • Enhances immune function and pathogen control
  • Helps regulate with both diarrhea and constipation by maintaining gastrointestinal health.
  • It also produces anti-inflammatory compounds, antioxidants, and other metabolites to promote overall health.

Lactobacillus plantarum (TBC LP-36™): 

  • Is one of our proprietary strains proven, through genetic analysis, to produce butyrate and reduce glutathione shown to decreases inflammation and oxidative stress.
  • In addition, this strain produces antibacterial substances which target pathogens, and help restore your gut microbiota.

Bifidobacterium bifidum: 

  • Interacts with the immune system by producing a variety of molecules that act as essential communicators with the immune cells in the mucosal lining of the gut.
  • It also stimulates growth of other commensal bacteria that produce butyrate to support the gut lining.

Lactobacillus ruminis (TBC LR-73™) 

  • Is a proprietary strain from BiotiQuest®.
  • Its primary job is immune modulation and pathogen control by producing antimicrobial substances.
  • This strain is a strong inhibitor of food borne pathogens like Listeria and Salmonella.

Leuconostoc mesenteroides (TBC LM-37™): 

  • Converts glucose and fructose to mannitol, a powerful free radical scavenger.
  • It produces anti-inflammatory substances
  • Protects the gut lining
  • Makes vitamin B12. B12 keeps nerves and blood cells healthy, helps make DNA, and plays a role in the production of the antioxidant, melatonin.

Lactobacillus rhamnosus: 

  • Produces muramyl dipeptides which may support immune health and increases the production of butyrate to support a healthy gut lining.
  • It’s one of the most well-studied probiotic species known to benefit digestive health.

Lactobacillus acidophilus: 

  • Provides nutrients to support the growth of B. subtilis, B. bifidum and S. thermophilus supporting more sustained action by the formula.

Streptococcus thermophilus:

  • Is a classic yogurt strain, very effective in supporting the immune system, improving digestive health, and outcompeting unhealthy bacteria.
  • It produces anti-inflammatory substances.

Our formulas are balanced for sustained action, which means they work longer and are stronger. Restore the balance of bacteria in your gut and rediscover your best health. Order today!

    Hi Lori,

    Thank you for trying BiotiQuest and for sharing your honest feedback. We're truly sorry to hear that our products didn’t help — and especially that you felt your symptoms may have worsened. That’s never the experience we want anyone to have.

    We noticed you purchased Sugar Shift, Antibiotic Antidote, and Ideal Immunity — a powerful combination aimed at supporting gut balance, microbial recovery, and immune resilience. Sometimes when starting new probiotics, especially more targeted ones like ours, the body can respond with a temporary adjustment phase. But we’d never want you to feel worse.

    If you’re open to it, we’d love to better understand your goals. What originally led you to try these products? Were you working through a specific health concern, post-antibiotic recovery, or something else entirely?

    Knowing a bit more about your experience will help us guide you toward a more gentle or better-suited approach. Every person’s microbiome and healing timeline is different — and we’re here to walk that journey with you, not just sell a product.

    Please feel free to respond here or reach out to us at info@biotiquest.com. We genuinely want to support you in finding your best path forward.

    With care,
    Jack
    BiotiQuest®️ Probiotics

    After an extended use of Amoxicillin I ordered this and am really happy I did. It stabilized my bowel movements immediately. Would highly recommend.
