After a brain hemorrhage, neural support cells called astrocytes enhance healing by transferring their mitochondria to damaged neurons. The healthy mitochondria stimulate the production of a free radical-fighting enzyme, according to new research published in The Journal of Neuroscience.
An artery in the brain bursts. Blood rushes into the tissue, inducing free radicals that cause even more damage. The hemorrhage damages mitochondria, the site of energy production in cells. Astrocytes transfer their mitochondria to damaged neurons after a hemorrhage. These healthy mitochondria contain a "healing" peptide called humanin and an enzyme called manganese superoxide dismutase (Mn-SOD) that help neutralize free radicals.
Tashiro et al. injected mice with healthy mitochondria after a hemorrhage. The hemorrhage reduced levels of Mn-SOD in the mice brain and increased the number of free radicals. Using molecular tags, the researchers found that the rodents' neurons took up the mitochondria from the bloodstream. The mice who received the treatment showed improved neurological recovery, but the benefits decreased if the mice received mitochondria without the Mn-SOD enzyme. These results reveal mitochondria can transfer between brain cells to improve health and aid recovery.

To get the specific Mn-SOD made, as listed here, one would likely take the taurine with a source of manganese (Mn). Do note the Upper Tolerable Limit (total) is 11 mg for adult men, per day.
I’ll post the taurine-SOD study, next.
Study shows that the amino acid taurine could be used in anti-aging therapy:

Somebody pleas inform Chris Wray that MY brain has no “free radicals”!!!
Mitochondria may be at root of dangerous complications from injury:

Mitochondria are evolved bacteria. When we experience physical trauma mitochondria spill into surrounding tissue. The immune system can recognize it as a bacterial attack, induce inflammation, and attack the remaining well tissue. This may not occur in the brain because of the blood-brain barrier and because of astrocytes.
My brain hemorrhages every time I hear the word “Democrat”.
For some reason, I was impressed by mitochondria in 9th or 8th grade biology class. And it keeps coming up in important biology news.
Add a little taurine to your shots.
