This long-fermented yogurt with Lactobacillus reuteri is an exceptional probiotic. Prepared with a controlled fermentation of 36 hours, it produces an extremely concentrated culture, much more powerful than probiotics in capsules. L. reuteri used to be present in almost all humans, but it disappeared with antibiotics, industrial food, and modern additives. It was "rediscovered" after being isolated in the breast milk of a young Swedish mother, revealing its profound role in immunity, development, and well-being. Its potential benefits include: - natural increase in testosterone - stimulation of oxytocin (mood, sleep, stress reduction) - powerful anti-inflammatory effect - interest in certain cases of SIBO - digestive and immune support Result: a dense, firm, and non-separating yogurt, a powerful homemade probiotic, stable and truly effective.
