Aggressive brain cancer may respond to high-dose vitamin therapy, study suggests

High-dose vitamin B3 (niacin) may enhance immune activity and improve short-term disease control in glioblastoma when added to standard therapy, according to early preclinical studies.

Glioblastoma is a highly aggressive, fast-growing brain cancer that develops from cells in the brain and spinal cord.

In previous laboratory experiments in mice, niacin was shown to extend survival. Researchers at the University of Calgary aimed to determine whether that same benefit extended to humans.
