Do supplements reduce lactic acid buildup?

Lactate is part of normal metabolism, not trapped waste that explains next-day muscle soreness. Some sports supplements affect buffering during intense exercise, but that is different from clearing a toxin or treating delayed soreness.

Correct the premise first

Cleveland Clinic explains that lactate rises during demanding activity and is processed by the body. Delayed soreness after exercise is not caused by lactic acid remaining in the muscles. A product promising to flush it away is therefore using an unreliable explanation for that symptom. [1]

Buffering supplements have specific uses and drawbacks

ODS discusses beta-alanine, which supports muscle carnosine, and sodium bicarbonate, which can affect acid buffering in selected high-intensity exercise. Performance findings do not apply equally to every sport. Tingling with beta-alanine and gastrointestinal effects with bicarbonate matter; neither is an everyday soreness remedy. [2]

Distinguish exercise discomfort from illness

Imagine ordinary soreness the day after an unfamiliar workout. A lactate-clearing stack is not the logical response. Unusual severe weakness, dark urine or persistent symptoms need medical assessment. Lactic acidosis in illness is a separate medical problem, not something to self-treat with a workout supplement. [1][3]
