If you’re worried about those little slips of memory that happen when you age and forget where you’ve put the keys, a phone number or someone’s name, there’s some new research on the benefits of magnesium. It also offers optimism.
Researchers from Beijing’s Tsinghua University and the Massachusetts Institute of Technology (MIT) discovered that increasing the amount of magnesium you consume could help prevent memory loss as we age.
Experts think that our cognitive abilities can be affected by how we consume our food. Researchers point out that 32 percent of Americans do not get the recommended daily intake of magnesium.magnesium glycinate This is a worry for many people and an opportunity to learn more.
For adults the recommended daily dose of magnesium is 400 mg/day for men and 300 mg/day for women who are yet to give birth.
Adults over 31 years old need to consume 420 mg/day women, and 320 mg/day for males. “Magnesium is essential for proper functioning of many tissues in the body including the brain, in an earlier study, we demonstrated that magnesium promoted synaptic plasticity in brain cells that were cultured,” explains Guosong Liu director of the Center for Learning and Memory at Tsinghua University in Beijing. “It was tempting to go one step further to investigate whether an increase in magnesium levels enhanced cognitive functioning in animals.”
The results of the study are believed by experts to be used to help people regardless of the fact that the test was carried out on rats.
The study appears in the January 28, 2010 issue of journal Neruon, and demonstrates that increasing brain magnesium using a new compound, magnesium-L-threonate (MgT for short), aids learning, working memory as well as short and long term memory in rats.
Researchers also found older rats did better in a series of tests. In 2004, Guosong Liu and his team at MIT first realized that magnesium may aid in memory and learning. They then followed up by developing a new magnesium compound, which has been proven to be better than conventional supplements in bringing up levels of this mineral within the brain.
The team also looked at the way MgT stimulates changes in synapses. Synapses are the points of contact between neurons that are essential for transmitting nerve signals. Both young and old rats showed an increase in synaptic power because of MgT. This increased the density of the hippocamp. This is the brain area that plays a crucial role in long-term memory and spatial navigation.
“This study does not only highlight the importance of a healthy diet that includes enough magnesium in the daily diet, it also suggests the value of magnesium-based treatments in aging-related memory decline,” is the study’s author Susumu Tonegawa. Tonegawa is a researcher at the MIT’s Picower Institute for Learning and Memory.
Realizing that aging can cause some reduction in the capacity to recall memories when not all information is available in a coherent manner, the researchers carried out other studies as part of their study.
They discovered that MgT treatment boosted memory recall in partial information circumstances in older rats but not in younger ones.
The study’s authors point out that the rodents used in the study had been fed a normal diet containing adequate magnesium. The study revealed that magnesium levels were increased in a way that was higher than the levels normally found in diets.
According to Liu who is the author, half of world’s population is thought to be suffering from magnesium deficiency. These results could have a huge impact on health for the population if MgT can be shown to be healthy for humans and efficient. Magceutics is cofounded by Liu. The company develops treatments to prevent and treat cognitive decline due to age as well as Alzheimer’s disease.
A diet that gives you sufficient daily magnesium is a sensible, natural option to preserve your mental function, and may be useful if you’re fighting age associated cognitive decline.
Research is ongoing on the benefits of magnesium on improving memory, and more research is required to examine the connection between the magnesium you get from your diet, in addition to body and brain magnesium levels as well as cognitive abilities.
