TBI and concussion symptoms cannot be cured or improved with dietary supplements. The US Food and Drug Administration released a warning to the public about false claims being made by companies hoping to profit from the despair and misfortune of others.
There is no scientific evidence that supplements can speed healing times or cure concussions. Daniel Fabricant, Director FDA dietary supplement program, released a news statement clearly stating that many of the supplements being marketed as cures and treatments are completely untested and may in fact be dangerous often containing high levels of omega-3 fatty acids. The FDA is also concerned that people gain a false sense of wellness and potential recovery when taking these supplements, and that they aren't taking the steps to allow their concussions to heal properly returning to full activity too soon.
Experts have known that subsequent concussions come easier and are more severe each time. According to Gary Coody, the FDA's national health fraud coordinator:
"We're very concerned that false assurances of faster recovery will convince athletes of all ages, coaches and even parents that someone suffering from a concussion is ready to resume activities before they are really ready...Also, watch for claims that these products can prevent or lessen the severity of concussions or TBI."
Some of the supplements are even being market as being able to prevent or lessen concussion symptoms. This is an extremely dangerous claim to make as they are completely untrue. The only way to prevent concussion is to not get one.
