Market Trend｜The Growing Demand for Vitality in an Aging
Society
According to the World Health Organization, the global population aged 60+ is projected to nearly double—from around 12% (1 billion people) in 2020 to 22% (2.1 billion) by 2050. Additionally, the share of those aged 65+ is expected to rise from about 10% today to 16% by 2050.
As we age, many experience fatigue more
easily. The key lies in declining muscle mass and strength. Studies show that
starting at age 40, muscle mass decreases by about 8% every decade,
accelerating to 15% per decade after age 70. This not only affects physical
mobility but also makes daily activities more exhausting.
Latest Research｜Lacticaseibacillus paracasei NB23 Enhances Vitality in Aging
A recent study published in Nutrients investigated the effects of Lacticaseibacillus paracasei NB23 supplementation in mice, focusing on energy metabolism, muscle performance, and fatigue-related markers.
Key Findings:
Improved Energy Storage
Mice supplemented with Lacticaseibacillus paracasei NB23 showed increased glycogen reserves in both the liver and muscle, indicating better energy supply for daily activities.
Reduced Fatigue
After exercise, Lacticaseibacillus paracasei NB23 mice had lower levels of blood lactate and ammonia, suggesting faster recovery and less exercise-induced fatigue.
Metabolic Balance Support
Lacticaseibacillus paracasei NB23 supplementation was associated with positive changes in markers related to metabolism and circulation, indicating potential benefits for systemic stability.
