### ⭐⭐⭐⭐⭐ One of many supplements that may reverse dementia and aging of the brain.
*by J***. on September 13, 2013*

Acetyl-L-Carnitine is one of the supplements that I have been giving my 93 year old mother to help reverse the effects an aging brain that has caused dementia. Most of the supplements are various antioxidants that help to protect brain cells and encourage new cell growth. This one is an amino acid which is a building block of protein that is naturally produced by the body and also found in food. As we age, the production of this protein declines. Acetyl-L-Carnitine readily convert to acetylcholine, a neurotransmitter that is critical for learning and concentration. Carnitine is a neuronal energizer and is essential for the production of energy by the mitochondria, the "powerhouse" of the cell. It transports fatty acids to the mitochondrial membrane where they are made into energy, and also helps remove waste products from the mitochondria-created energy production. In the last few months, I have done quite a lot of research on the reversal of dementia. This is only one of a few supplements that will support regeneration of new brain cells. Many supply various antioxidants that the body no longer produces, some rebuild mitochondria, and some rebuild neurons and help to develop new synaptic connections. Brain cells that have been killed by dementia can never be resurrected, but the brain will constantly grow if given the nutrients and tools that it needs to do so. I won't go into all we have done for my mother, or all of the improvements we have seen, but I can assure you that dementia or Alzheimer's is not an end-all. There really are things that can be done to stop and even reverse both. I have seen the results in my mother. In addition, through diet and supplement, we have reduced her medications from 10 to 1, and, according to her doctor, she has the blood work of a 20 year old. Not bad for a 93 year old lady!!
