Strength training plus cardio cuts type 2 diabetes risk the most

A 20-year prospective cohort study of 143,715 US healthcare professionals found that long-term resistance training was associated with a substantially lower risk of type 2 diabetes. The lowest risk was seen among participants who combined regular resistance training with adequate aerobic activity and limited TV viewing.

Trial identifies 4 grams a day as the tested safe level for L-tyrosine in healthy men

A randomized, crossover trial in healthy adult men found that 4 weeks of L-tyrosine supplementation at doses up to 4 g/day did not cause clinically meaningful changes in safety markers, diet, blood pressure, or body measures. The highest tested dose, 4 g/day, was identified as the no-observed-adverse-effect level under the study’s four-week conditions, although broader and longer-term studies are still needed.
