Benefits of Magnesium - Effective Supplements for Memory
Benefits of Magnesium - Effective Supplements for Memory - If you are worried about the small memories that come with age, such as when you put a key, telephone number, or someone's name, then there is new work about the benefits of magnesium that offers hope.
Neuroscientists at Massachusetts Institute of Technology (MIT) and Tsinghua University in Beijing found that increasing magnesium intake - an important mineral in dark leafy vegetables and some fruits, nuts and beans - might only help memory aberrations that occur with age. .
Many experts believe that a diet can have a sufficient impact on our cognitive capacity, and the researchers point to estimates that only 32% of Americans get recommended daily magnesium intake, as a reason for worry and reasons to learn more.
The recommended amount of magnesium for adults is 400 milligrams / day for men; 310 milligrams / day for non-pregnant women.
Adults over 31 must get 420 milligrams / day for men; 320 milligrams / day for non-pregnant women. "Magnesium is very important for the functioning of many tissues in the body, including the brain and, we show that magnesium increases synaptic plasticity in brain cells as previously done". Therefore it is tempting to take our study a step further and investigate whether increased levels brain magnesium improves cognitive function in animals. "
Even thought the experiment was conducted in mice, experts believe that the findings also have implications for humans.
The study appears in the January 28 issue of Neruon, and shows that increased brain magnesium uses new compounds, magnesium-L-threonate (MgT in short), helps learning, working memory and short and long term memory in mice.
The mineral also helps older mice perform better in a series of learning tests conducted by researchers. It was in 2004 that Guosong Liu and his team at MIT first discovered that magnesium can help memory and learning, following up by developing new magnesium compounds that proved to be better than conventional supplements in increasing levels of this mineral in the brain.
The team then examined how MgT stimulated changes in synapses. Synapses are junctions between neurons which are key to sending nerve signals. In young and old mice, MgT increases strength among synapses, promotes density in the hippocampus, an area of the brain that plays an important role in spatial navigation and long-term memory.
"This study not only highlights the importance of a diet with sufficient daily magnesium, but also suggests the usefulness of magnesium-based treatments for decreased memory-related aging," said study author Susumu Tonegawa, who works at MIT's Picower Institute for Learning and Memory.
Realizing that aging does indeed cause a decrease in memory recall when not all information is presented, the researchers conducted other experiments as part of the study.
They found that MgT treatment improved memory under conditions of partial information in older mice, but did not affect the younger ones.
The study authors showed that the control mice in this study ate normal foods that had sufficient amounts of magnesium. The effect observed in the study was due to an increase in magnesium to a higher level than what you get in a normal diet.

Half of the world's industrial population is believed to have magnesium deficiency according to researcher Liu. "If MgT is proven safe and effective in humans, this result might have a significant impact on public health." Liu is one of the founders of Magceutics, a company that creates medicines for the prevention and treatment of age-related memory decline and Alzheimer's disease.
A diet that gives you enough daily magnesium is a smart and natural step to help maintain your mental functioning, and may be useful if you are struggling with age-related cognitive decline.
Research is ongoing on the benefits of magnesium in improving your memory and more work needs to be done to investigate the relationship between the magnesium you get in your food, as well as the body's and brain's magnesium levels and cognitive skills.
