No, there is no evidence that vitamin B12 or folic acid supplements can improve our memory. That’s the verdict of researchers at Wageningen University in the Netherlands, where scientists measured the memory and thinking skills of nearly 3,000 people, average age 74. HealthDay reports that half of the study group took 500 micrograms of vitamin B12 and 400 mcg of folic acid every day for two years. The other half took a placebo. All of the participants had high levels of an amino acid called homocysteine, which has been linked to memory loss and Alzheimer’s disease. The envelope please….After two years, tests of memory and thinking skills showed that those taking the vitamin B12-folic acid supplements did have larger decreases in homocysteine levels than those taking the placebo, but despite that decrease, there was no difference between the two groups on the thinking and memory tests. No, there is no evidence that vitamin B12 for folic acid supplements can improve our memory. Oops, already said that.
