Green tea extract concentrates the active compounds of the tea leaf, offering benefits for metabolism, brain function, and liver health. New research highlights its role in reducing blood pressure and supporting the gut microbiome, though dosage matters for safety.
Are squats really the only leg exercise you need? New research compares squats directly against leg extensions, revealing that each exercise targets different parts of the quadriceps.
Restless Legs Syndrome (RLS) and Periodic Limb Movements (PLMS) are complex neurological disorders linked to iron deficiency and dopamine dysfunction. This guide explains the latest research on triggers like antidepressants, the connection to heart health, and why treatment guidelines are shifting away from dopamine agonists.
Vitamin E is essential for protecting cell membranes, but supplements often fail to deliver the expected health benefits. We break down the science of why food sources are superior and which specific conditions actually respond to supplementation.
Garlic is a potent antioxidant, but how you prepare it matters. Research shows that sprouting, aging (black garlic), and the "10-minute rule" can significantly boost its health benefits.
BCAA supplements are among the most popular in fitness, but research shows their benefits depend heavily on context. They may help reduce soreness and preserve muscle when protein intake is limited, but offer little extra for people already eating enough protein.
A year-long study of 51 adults found that a multi-ingredient supplement was associated with reduced biological age in the liver and lungs, as measured by epigenetic clocks. But with no placebo group and mixed results across different aging markers, the findings are preliminary and need further confirmation.
GLP-1 weight loss drugs like semaglutide and tirzepatide show real promise, but real-world results often fall short of clinical trial numbers. A 2025 review reveals that adherence is the key factor, with half of users quitting within a year, and explains what we know about side effects.
A major 2025 review in Nutrients examines the link between vitamin D and kidney health. Observational studies suggest that CKD patients with adequate vitamin D levels have significantly lower mortality rates, but the evidence has important nuances worth understanding.
Scientists have engineered modified versions of GHRH, a brain hormone that triggers growth hormone release. In animal studies, these synthetic analogues show potential for protecting hearts, fighting tumors, supporting insulin-producing cells, and reducing inflammation, though none have yet been proven in human clinical trials.
