Nitroglycerin that patients with anginal chest pain take under the tongue to relieve chest discomfort works by releasing nitric oxide which is vital to arterial health and dilates arteries. Statins switch on AMPK which increases nitric oxide production. Statins are also antiinflammatory and antioxidant. Does that help you understand why they have such a potent benefit in heart disease?
But the statins also potentate metabolic diseases, e.g. type two diabetes. There are much safer options than this.
