Memory boosting folic acid, the latest vitamin to prove beneficial in the fight against dementia

It's not just mums-to-be who need to supplement their diet with folic acid, research has now linked it to reducing the risk of a host of health problems, including dementia, and experts say we should all raise our daily intake1.

Folic acid, also known as vitamin B9, is essential for nerve function and the formation of DNA and healthy red blood cells. Several studies have shown a link between low folic acid and a higher risk of Alzheimer’s disease. The beneficial action folic acid has on homocysteine is thought to be behind this link, too, as research has long suggested high levels contribute towards dementia. 2

The Department of Health currently recommends adults should get their 200mcg daily intake through food, while those trying for a baby or pregnant are advised to take a 400mcg supplement, too. Yet figures from the UK’s National Diet and Nutrition Survey show there’s been steady decline in folic acid intake over the past 11 years.3 This is thought to be partly due to the fact that our modern diet of processed foods contains very little folic acid. The current 200mcg daily recommendation is equivalent to eating 12.5 boiled eggs or 15 kiwi fruits a day! Never has there been a more prevalent time to supplement your diet with additional folic acid.

Manuka Doctor’s Forget Bee Not nutritional supplement contains 400mcg of folic acid, twice the current daily recommendation, along with other memory boosting ingredients, including;


B vitamins work together to perform essential roles in our bodies, particularly brain function. A surprising number of us could be lacking, particularly in vitamin B12. US research has found large doses of B vitamins could halve the rate of brain shrinkage in elderly people with memory problems, and therefore help to slow the progression of dementia. Similarly, a two-year UK trial at Oxford University found B vitamins – including B6, B12 and folate – could slow mild cognitive impairment, which often leads to Alzheimer’s disease and other forms of dementia.4


According to a study by Dr Martha Morris and colleagues at Chicago’s Rush Institute for Healthy Aging, eating fish once a week reduces your risk of developing Alzheimer’s by 60 per cent. The researchers followed 815 people for seven years and found that dietary intake of fish was strongly linked to Alzheimer’s risk. They found that the strongest link was the amount of DHA, a form of omega 3-fat. The higher a person’s DHA, the lower their risk of developing Alzheimer’s. Studies suggest that DHA may help prevent cognitive decline before the development of Alzheimer’s.5

Iron, Zinc & Iodine

Certain trace elements are essential for brain growth and function. From a human health perspective, the elements of greatest importance are iodine, iron, zinc, copper, manganese, mercury and lead.5

Micronutrient deficiencies, especially those related to iodine and iron, are linked to attention span, intelligence, and sensory perception functions, as well as those associated with emotions and behaviour.6

Zinc is essential for the activity of many enzymes. Impairments in activities of these and other enzymes by zinc deficiency may account for some of the effects of zinc deficiency on the brain.7

Royal Jelly

Royal jelly, a wonderful substance produced by worker honeybees, has shown significant neuroprotective actions.8 Queen bees are fed their whole life with Royal Jelly and worker bees receive this food for a short period during the larval stage of life. Queen bees live for 1–5 years, but worker bees only for 3–6 weeks. When administered orally, data suggests that Royal Jelly may be a promising tool for improving memory and cognition.

Royal Jelly has also shown to be effective in supporting Alzheimer’s patients while assisting memory and brain function by using its antioxidant power, while potentially preventing neurodegenerative diseases. These are peptides support the growth and survival of neurons in the brain, essential for learning and memory.9

While there is currently no known cure for Alzheimer’s or ways to significantly enhance learning and memory, Royal Jelly may be able to increase the sharpness of your mind and memory ability.10

What is dementia?

Dementia is an umbrella term used to describe a range of neurological disorders which impact memory, thinking and behaviour. There are many different types of dementia, of which Alzheimer’s disease is the most common. Some people may have a combination of different types of dementia. Regardless of which type is diagnosed, each person will experience their dementia in their own unique way. Here are a few symptoms or warning signs:

  • Difficulty with Language, forgetting the name of objects or everyday words.
  • Repeating the same questions over and over again.
  • Being unable to recognise familiar people, places or voices.
  • Lack a sense of direction or becoming disorientated.
  • Lose the sense of time.
  • Lack a sense of hygiene.
  • Inability to recognise situations that are unsafe or could result in being vulnerable.
  • Decreased sense of the importance of nutrition.

Although there is currently no known cure for Dementia there are several lifestyle changes one can make to help keep the mind sharp and delay the onset of neurological disorders.

How to help prevent dementia..

Exercising your heart, muscles and lungs can boost brain chemicals that help ward off dementia. Older adults who did aerobic exercise (such as running or cycling) three times a week for a year grew larger hippocampi (the hippocampus is a brain area intimately involved in memory), and performed better in tests of memory, according to a 2011 study in the journal Proceedings of the National Academy of Sciences.

Meanwhile, a good night’s sleep can help clear out potentially damaging brain gunk each night. Trials suggest fixing sleep problems can slow the rate of cognitive decline and delay the onset of Alzheimer’s by up to ten years. 11

Leisure activities and hobbies are just as important to health as diet and exercise, whilst laughter is good medicine as it helps to relieve stress.

Reading engages your brain in an activity that is mentally stimulating and can greatly reduce your chances of developing dementia. Reading an interesting novel can help you to temporarily escape your own stressful thoughts that may be bothering your mind.

A good diet can also add years of healthy cognitive function. A team from Rush University Medical Centre in Chicago found that those who stuck to a Mediterranean diet had brains that were nearly six years younger than their peers on the Western diet. The Mediterranean diet features more fruit and fish and limiting sugar, dairy and processed foods. Previous studies have found that it could help keep the mind sharp and reduce frailty in older individuals.

Supplementing your diet with certain vitamins, minerals and herbs has also proven effective in improving cognitive function and memory.
