Spore Forming Soil Based Probiotics: Modern farming and modern processing practices have removed beneficial soil-based probiotics from our food. Our SBO Probiotic populates the gut with healthy organisms to create balance in the microbiome. With spore probiotics that include Bacillus subtilis, Bacillus coagulans and Bacillus clausii, our premium SBO probiotic is formulated to replace the spore forming probiotics that have been missing from the modern diet.

Supports Healthy Digestive Systems: Soil based probiotic supplements for men and women taken daily can help promote overall digestive health. By taking an SBO probiotic with spore-forming bacillus strains, you can ensure that your microbiome is supported with beneficial organisms.

Organic Fermented Supplement: Our soil-based probiotic includes fermented barley, fermented ginger and organic apple cider vinegar. Fermented foods are natural sources of probiotic organisms, and barley and apples are natural prebiotic foods that help feed probiotic organisms so they can thrive in the gut. Organic apple cider vinegar and ginger are natural antioxidants as well, providing a complete supplement that supports healthy microflora in the body.

Shelf Stable Bottle and Capsules: Soil-based probiotics like Bacillus subtilis are more durable and stable than dairy-based probiotics. SBOs were historically intended to be a part of the diet, so they’re more durable and more likely to survive. Our 60 Billion CFU SBO Probiotic is shelf-stable, comes in a patented shelf-stable bottle and is protected by delayed-release capsules to ensure that more of the beneficial soil based organisms can populate the gut. Refrigeration is not required.

Safety Assured Standard of Quality: Our SBO Probiotic is 3rd-party tested for purity and manufactured in a US cGMP-Certified facility using imported and domestic ingredients. Unlike some leaky gut supplements, our SBO probiotic contains 60 billion CFU, including Lactobacillus paracasei, L. plantarum, Bacillus clausii, B. subtilis, B. coagulans and Saccharomyces boulardii. SBO probiotics for women and men are used for bloating and constipation support.

GLUTAMINE YOU CAN TRUST: Supersize your gains with L-glutamine powder that keeps it clean. While most brands take the easy route and source their glutamine from bird feathers, animal fur, or human hair, Kaged Muscle glutamine exclusively comes from plants. We use an innovative fermentation process to get our vegan glutamine from 100% plant-based sources. The result? A clean glutamine supplement you can take with confidence while still reaping all the performance-boosting benefits.

HIGHER ABSORPTION; BETTER RESULTS: Get the most out of every scoop. This isn’t just any glutamine powder; it’s microencapsulated. We’ve used patented technology to coat our glutamine in a unique plant-based protein matrix. So, unlike other powders that are destroyed by stomach acids before they even get to the gut, ours gets to the small intestine intact, dramatically enhancing absorption. Go ahead, experience the true power of glutamine with a supplement that unleashes its real potential.

TRANSFORM YOUR BODY: Being training hard and getting in your daily recommended intake of protein? Great! But gulping down that shake and tearing through that steak is just part of the equation; how much protein you absorb matters just as much. And that’s where our fermented glutamine comes in. It increases muscle protein synthesis to help you build that lean muscle you have your sights on. Pair it with our wildly popular protein shakes and make that dream body a head-turning reality.

SLASH YOUR RECOVERY TIME: Whether you just endured a brutal leg day, arduous distance run, or epic adventure on your bike, our ultra-pure glutamine helps you get back to doing what you love much sooner. Glutamine levels drop whenever you get in a good workout; one of the reasons behind muscle soreness when you push yourself past your limit. Pre-Kaged L-glutamine contains 5g of this recovery-enhancing powerhouse in every scoop. Powder that is 3rd party tested and contains no artificial flavors.

QUALITY WITHOUT COMPROMISE: Our mission is simple: deliver scientifically backed, superior, but affordable supplements that contain top-notch ingredients and utilize the most innovative technologies. We strongly believe every supplement should be rooted in real science, and above all, safe. We source the purest, most potent raw materials, perform extensive laboratory and real-world testing, and have an unwavering commitment to quality. Go ahead, sample the finest glutamine powder!
