KetoneAid is a pioneer in exogenous ketone esters, creating high‑potency formulas that provide your body with a ready source of ketones—the “superfuel” you normally produce during fasting or ketosis. Their flagship drink, KE4 Pro, contains pure D‑β‑hydroxybutyrate (BHB) bound to (R)‑1,3‑butanediol, delivering 2.5 grams of ketone ester per 5 ml shot; reviewers call it one of the few true ketone ester drinks available and note that ketone esters are the most effective form of exogenous ketones for endurance and mental performance. The company also offers KE1, a milder blend of ketone esters and salts for those sensitive to taste. All products are sugar‑free and caffeine‑free, providing clean energy without jitters, and every batch is made in the USA, third‑party tested for WADA compliance and FDA GRAS approved. With KetoneAid, you can quickly raise ketone levels to sharpen focus, boost endurance and support metabolic health.
