While many use the terms 'Alzheimer's disease' and 'dementia' interchangeably, technically Alzheimer's is one form of dementia and is the sixth leading cause of death in the U.S. Over 5 million Americans live with this disease, and one-third of seniors die with some form of dementia. The cost of treating Alzheimer's is enormous. While the documented cost to the nation of treating Alzheimer's in 2013 was over $203 billion, the unaccounted cost borne by family members was estimated to be over $216 billion in 2012.
This article examines whether niacinamide, which is a form of Vitamin B3, is helpful for symptoms relating to Alzheimer's and Dementia, such as memory loss.
Someone in the U.S. develops Alzheimer's every 68 seconds. Twice as many 70 year olds with Alzheimer's die before they are 80, compared to 70 year olds who do not have Alzheimer's. There is no way to prevent, cure or slow the progression of Alzheimer's, though the quest for treating Alzheimer's has spawned a sprawling, world-wide industry, supporting conferences, chains of nursing homes, expensive new drugs, on top of the ongoing costs of the physical care of patients.
Niacin Vs Niacinamide
The main role of vitamin B3 is to make NAD molecules.
NAD, which stands for nicotinamide adenine dinucleotide, is the coenzyme form of Vitamin B3, which is found in every single living cell.
NAD plays critical roles in cellular energy production (as ATP) and several signaling pathways (e.g., sirtuins, PARPs). It is also involved in aging. Unfortunately, NAD decreases as we age, but this is where Vitamin B3 supplementation can help.
Niacinamide is one of 3 forms of vitamin B3, also known as Niacin. Another form of B3 is called nicotinic acid. A third form is called inositol hexaniacinate, which is similar to niacin.
Niacinamide is made from niacin. Even though the body can convert niacin to niacinamide, there are a critical differences between these two vitamin B3 components.
Research has found that niacinamide can be used to make NAD even more effectively than niacin. Furthermore, niacinamide does not produce prickly, flushed skin that niacin does.
Traditionally, niacin is taken to support healthy cholesterol levels, while niacinamide is used as support for sugar balance, brain function and painful joints. Niacinamide does not affect cholesterol balance.
Niacinamide for Alzheimer's
Niacinamide has been used safely for at least 60 years, primarily to treat arthritis but also as a treatment for Alzheimer's.
Psychiatrist and clinical researcher William Kaufman published the first documented account of the use of niacinamide in the treatment of Alzheimer's in his 1943 publication, The Common Form of Niacin Amide Deficiency Disease: Aniacinamidosis.
In his book, he reported that patients who were deficient in niacinamide had the following symptoms:
- impaired memory
- inability to concentrate
- difficulty in comprehending and reading
- anxiety
- uncooperativeness
- inability to complete projects or tasks
- quarrelsome
- dissatisfied
These symptoms, bearing an uncanny resemblance to the symptoms of Alzheimer's disease, "disappeared... or improved considerably" on treatment with niacinamide.
Subsequent publications by Kaufman focused on the use of niacinamide in the treatment of degenerative arthritis. Kaufman came to the conclusion that niacinamide was not to be seen as a cure, but as a permanent supplement, as stopping the dosage brought back a resurgence of symptoms.
Niacinamide Research On Mice
A 2008 study published in the Journal of Neuroscience with demented mice showed that treatment with niacinamide reversed Alzheimer's by causing a 60% reduction in one of the Alzheimer markers and increasing the number of microtubules that carry information inside the brain cells (1).
A 2012 study on lab mice reported that niacinamide restored cognitive functioning and synaptic plasticity (2).
A 2013 study concluded that niacinamide prevented cognitive decline in Alzheimer's mice through improved neuronal activity and reduced breakdown of brain tissue (3).
Jonathon V. Wright, M.D. reviewed 2008 studies on laboratory mice and concluded that there was no reason to wait for 'more research' before administering niacinamide to Alzheimer's patients (4).
Niacinamide Research On Humans
The University of California, Irvine, (conductor of one of the above-mentioned mice studies) is working with the Alzheimer's Association to study the side effects of treating Alzheimer's with niacinamide.
Niacinamide Dosage
Modern-day studies have been based on Kaufman's findings on dosage. Kauffman argued for the effectiveness of having the dose spread out, as opposed to being administered at one go (6,7).
UK-based physician, Dr. Sarah Myhill ,prescribes niacinamide for a number of problems and reports she has never had a patient develop liver problems at high doses (over 500 mg. daily). She agrees with Kaufman that the best results are achieved by taking low doses regularly spaced throughout the day (8).
Bottom Line on the Best Way to Take Niacinamide
If possible, taking 250 mg. every 90 minutes, 12 times a day seems to be the best method.
Sustained release (time release) niacinamide capsules are available on the internet and seem to be a reasonable compromise, though it is important to be aware that these doses are substantially above the Recommended Daily Allowances.
Summary
Niacinamide has been used safely for at least 60 years, primarily to treat arthritis, but also as a treatment for Alzheimer's.
Studies on mice concluded that niacinamide improved cognition. A human study has not yet been completed. Anyone over 60 with a family history of Alzheimer's and who fears getting the disease might want to consider taking niacinamide as a precaution. For those already suffering from Alzheimer's, niacinamide offers hope.
