Yogurt cultures are live microorganisms, primarily Lactobacillus bulgaricus and Streptococcus thermophilus, used to ferment milk into yogurt. These beneficial bacteria are classified as probiotics and are widely recognized for their role in promoting gut health. Their presence in the digestive tract contributes to the balance of the microbiome, which influences nutrient absorption, immune function, and even mood regulation.
In sports and fitness contexts, a healthy gut is essential for maintaining energy levels, preventing gastrointestinal discomfort during exercise, and optimizing nutrient uptake from food and supplements. Regular intake of probiotics like those in yogurt cultures may also help reduce inflammation and improve recovery.
Yogurt cultures are often included in functional foods and probiotic supplements, making them an accessible and practical option for active individuals looking to enhance their digestive health.

Sources:
Fermented dairy products (yogurt, kefir); also available in encapsulated probiotic supplements.
Observations:
Often found in combination with other probiotic strains in supplements. Requires proper storage (refrigeration or freeze-drying) to maintain viability. Generally safe, but individuals with lactose intolerance should opt for lactose-free or dairy-free probiotic alternatives.
