400-800mg nitrates 2-3h beforeNitric oxide improves blood flow for heat dissipation and reduces oxygen cost of exercise in heat
Buy on Amazon →Vitamin C
500-1,000mgSupports heat acclimatisation and reduces exercise-induced oxidative stress amplified by heat
Buy on Amazon →Sodium Bicarbonate
200mg/kg 60-90 min beforeBuffers the additional acid production from exercise in heat. GI tolerance is the limiting factor
