Life Extension Recommends Summer Supplements for Heat Protection
Life Extension advises four core nutrients to help people stay healthy during the summer heat. Research scientist Stephen Tapanes, Ph.D., says the body’s needs change with longer days, increased UV exposure and more sweat.
Vitamin C is highlighted for its antioxidant, immune‑supporting, heart, respiratory and collagen‑building benefits. Vitamin D remains important even in summer, especially for those who stay indoors, use high‑SPF sunscreen, are older or have darker skin, as it supports bone health, heart function, cognition and immune response.
Magnesium, particularly in a glycinate form, helps replace the electrolyte lost through sweat and supports over 600 biochemical reactions, including heart, bone, muscle and nerve health; athletes may need 10‑20 % more. Additional nutrients such as vitamin B3, zinc, probiotics and ceramides are mentioned for skin protection and gut health.
The guidance suggests planning outdoor activities during cooler periods, staying hydrated, checking vitamin levels and considering daily supplements of 500 mg vitamin C, appropriate vitamin D doses and magnesium glycinate to “heat‑proof” health through the summer months.
