It was thought that B vitamins could help your memory but new research proves otherwise. Results of a recent study show that taking vitamin B12 or folic acid supplements may not reduce risk of memory loss in seniors.
The study involved testing nearly 3,000 people with an average age of 74-years-old. Half of the test subjects took a tablet daily with 500 micrograms (mcg) of vitamin B12 and 400 mcg of folic acid for two years. The other half of the participants took a placebo every day for two years. According to the study, all 3,000 participants had high levels of homocysteine, an amino acid linked to memory loss and Alzheimer's disease.
The researchers concluded that participants who took the vitamin B12 and folic acid had reduced levels of homocyestine. "Since homocysteine levels can be lowered with folic acid and vitamin B12 supplements, the hope has been that taking these vitamins could also reduce the risk of memory loss and Alzheimer's disease," said Rosalie Dhonukshe-Rutten, of Wageningen University in the Netherlands in a news release.
However, despite the lower homocysteine levels researchers found there was no difference between the two groups when they were given thinking and memory tests.
The results may not be what we want to hear and further research will likely be done to investigate whether the link between homocysteine and Alzheimer's is as robust as we once thought. But in the meantime, It doesn’t hurt to keep taking your vitamins. Hopefully someday in then ear future we will have the right answer for curbing memory loss. Do you take vitamin B12 or folic acid supplements? What other remedies do you think can prevent memory loss?
