I’ve tried a couple of supplements and found mixed results. L-arginine helped with improved blood flow, but it’s subtle. Be cautious with products that contain yohimbine, as it can cause anxiety and rapid heartbeat for some people. Always consult with a healthcare professional before starting any supplement, as they can provide guidance based on your specific health needs. Researching and reading peer-reviewed studies can also offer some insights. Have you considered speaking with a doctor to explore safe options?
