Mayo Clinic Warns: Arginine Supplements Pose Heart Attack Risk

The Mayo Clinic has issued a warning regarding arginine supplements. While these supplements may offer some benefits, they also pose risks, particularly for those who have recently suffered a heart attack.

Arginine, an amino acid found in protein-rich foods, is used by the body to produce nitric oxide. This helps blood vessels relax and expand, regulating heart attack. Doctors may recommend arginine supplements for certain cardiovascular conditions or erectile dysfunction, as they can improve blood flow and alleviate symptoms.

However, the Mayo Clinic cautions against using these supplements after a heart attack. They warn that arginine supplements may increase the risk of dying in such cases. This is because arginine can stimulate the production of nitric oxide, which may not be beneficial in the aftermath of a heart attack. Most people obtain sufficient arginine through a balanced diet, making supplements unnecessary.

Some studies suggest that arginine supplements may have potential benefits for the immune system, aiding in wound healing and post-surgery recovery. They may also improve glucose tolerance, potentially aiding in diabetes treatment, although more research is needed to confirm these effects.

Arginine supplements, while potentially beneficial for certain cardiovascular conditions and erectile dysfunction, should be avoided after a heart attack due to the increased risk of mortality. Always consult a healthcare provider before starting any new supplement regimen. A balanced diet typically provides sufficient arginine, making supplements unnecessary for most people.
