We’ll focus on the KA EX Cortisol Stress Reducer+ Powder, a 3-pack supplement that combines phosphatidylserine with a full electrolyte and vitamin blend.

Clinical Evidence and Research Backing
Training hard triggers a natural cortisol release, but chronic elevation slows recovery and catabolizes muscle tissue. Phosphatidylserine helps blunt excessive cortisol spikes, allowing your body to shift into repair mode faster. Look for a supplement with clinical backing, like the KA EX formula, which has been shown to reduce cortisol by 36% in just 48 hours in three separate clinical trials.
