What precautions, adverse reactions and contraindications for each of the major ingredients in TRX2™ Molecular Hair Growth Supplement have been reported in scientific literature?
With regard to L-carnitine, the Supplement Monographs published by the Physicians Desk Reference (PDR) and the Natural Medicines Comprehensive Database (NMCD), both well-known reference guidelines, report mild gastrointestinal symptoms, including nausea, vomiting, abdominal cramps, heartburn, gastritis, diarrhea, body odor, and seizures. Other sources report an increase in agitation or restlessness. Some evidence suggests L-carnitine may interfere with thyroid metabolism. Oral niacin in amounts typically found in dietary supplements, are well tolerated. However, a flushing reaction can occur with doses of niacin as low as 30 mg/day, but occurs more commonly with the larger doses commonly used for treatment of hyperlipidemia. The reaction can consist of flushing, burning, tingling, and itching; sometimes with pain; as well as erythema of the face, arms, and chest. There may also be increased intracranial blood flow and headache.
