RiskMedium Risk
Overview
•Vitamin B6: 12.2 mg a day is above the 12 mg/day EU upper limit (EFSA 2023), though within the US limit of 100 mg/day. Taking more than this for months is linked to nerve damage (peripheral neuropathy: numbness, tingling or pain in hands and feet), which usually improves after stopping.
•Each capsule provides approximately 100 mg total caffeine (200 mg daily), which can cause jitteriness, insomnia, and palpitations if combined with other caffeinated products.
•Contains Citrus aurantium (providing 15 mg synephrine per capsule), an adrenergic stimulant that may raise blood pressure and heart rate, especially alongside caffeine.
•Contraindicated in pregnancy and breastfeeding due to combined stimulant levels exceeding recommended daily limits and lack of safety data for botanical extracts.
•Contains naturally occurring sulfites, requiring caution for individuals with known sulfite sensitivities.
•Caffeine and bitter orange constituents interact with hepatic enzymes (particularly CYP1A2) and may alter the clearance of prescription medications.
