Green Tea (Matcha)
High-quality matcha green tea powder rich in EGCG catechins and L-theanine. Provides calm, sustained energy while delivering powerful antioxidant and anti-inflammatory benefits. Regular green tea consumption is associated with reduced cardiovascular disease risk and improved metabolic health in population studies.
Probiotics (Multi-Strain)
Multi-strain probiotic supplement containing diverse beneficial bacteria to support gut microbiome health. A balanced gut microbiome is linked to improved digestion, immune function, and mental well-being. Look for formulas with clinically studied strains and high CFU counts.
