  • DIGESTIVE SUPPORT: Replenishes good bacteria and fights bad bacteria to support your digestive health with less gas, bloating, and discomfort. Your digestive health is key to your well-being, but it faces challenges every day from diet, pollutants in the environment, antibiotics, and more. Thats where a great probiotic can help.
  • IMMUNE SUPPORT: 80% of your immune system lives in the gut! A healthy gut means healthy immunity. Our formula contains the potent, well-studied strains Bacillus clausii and Bacillus subtilis HU58 to support immunity and immune system responses.
  • NATURES BEST PROBIOTICS: Spore strains are natures best design for probiotics. We use strains backed by research including Bacillus subtilis HU58, Bacillus clausii, and Bacillus coagulans, which are clinically proven to survive digestion. Many yogurts and other probiotic brands with up to 100 Billion CFUs (colony forming units) contain strains that arent made to survive digestion, like Lactobacillus and Bifidobacterium. With probiotics, choose quality over quantity every time.
  • CLEAN, HIGH-QUALITY FORMULAS: All Natures Instincts probiotics are soy-free, gluten-free, dairy-free, GMO-free & vegetarian, with no artificial colors, flavors, binders or fillers. We DNA-Verify every bottle to ensure you are getting exactly whats on the label. Sadly, not every probiotic can claim the same.
  • NO REFRIGERATION NEEDED: Natures Instincts probiotics do not require refrigeration, so they are convenient at home or for travel. Since our bodies are roughly 98.6 F, it only makes sense to choose a probiotic supplement that can withstand higher temperatures. If it needs to be refrigerated to stay alive, how will it survive the high temperature of your body when you digest it?
