VCQ-0412
When does a change in performance deserve medical evaluation instead of another supplement?
Professional evaluation becomes more important when a change is sudden, persistent, progressively worsening, associated with chest discomfort, breathlessness, fainting, pain or a major loss of exercise tolerance, or follows a medication change. A supplement comparison is more appropriate for a stable wellness decision than for unexplained or concerning symptoms.
