Myeloma and B Complex?
What is the interaction between myeloma and B complex vitamins? Having written about B12 and B6, and MM in years past, this article linked below jumped out at me. While I am all about MM, I am also all about the side effects of MM treatment that I live with, such as chemobrain and chemotherapy-induced cardiomyopathy.
I’m reluctant to post about another vitamin supplement, having written about curcumin, omega-3 fatty acids, vitamin C, vitamin D, and many others.
But here we are…
B Complex Vitamins: The Secret to Boosting Your Energy Naturally!
Multiple Myeloma Diagnosis- B12 Deficiency, MM?
As a long-term MM survivor, the bottom line is that while I work hard to consume a nutritious diet every day, there are many vitamins and minerals that older people’s bodies simply don’t make enough of. A deficiency of a vitamin can increase our risk of MM as well as our risk of short-term, long-term, and late-stage side effects.

How B Vitamins Can Affect Brain and Heart Health
“Eight essential nutrients make up the suite of B vitamins, also known as the B complex. Researchers from Tufts University and elsewhere have revealed that these B vitamins influence a vast spectrum of human health and disease, including
- cognitive function,
- cardiovascular health,
- gastric bypass recovery,
- neural tube defects,
- and even cancer.
“It’s hard to study the B vitamins in isolation,” says gastroenterologist Joel Mason…
One carbon metabolism is a series of pathways that allow for the transfer of single-carbon units to cells for essential processes such as DNA synthesis, amino acid metabolism, and more. It’s their role in all these crucial biological functions that make the B vitamins so important—and so challenging to tease out how they contribute positively and, perhaps negatively, to human health.
Mason and two additional researchers who spent their careers studying one or more of the B vitamins explain what we currently know about how the five of the most prominently researched B vitamins impact or improve cognitive as well as cardiovascular health.
Cognitive Health, B12, and Folate
One of the most active areas for B vitamin research is cognitive health. By the age of 75-80, 40% of people have a diminished ability to absorb food-bound B12, says Mason. This deficiency leads to a decline in nerve health, particularly in the spine and brain, which can contribute to the risk of developing dementia in older adults.
For decades, clinicians and researchers thought measuring plasma B12 was accurate enough to determine if supplementation was needed. However, Mason says, while many elderly people may have B12 levels that are in the ‘low to normal’ range, they are simultaneously developing neurological deficits linked to vitamin B12 deficiency.
“The contribution of vitamin B12 deficiency to cognitive decline and the vascular disease that results in many cases of dementia is under-diagnosed and under-reported,” says Irwin H. Rosenberg…
“Age-related cognitive decline is not just Alzheimer’s,” says Rosenberg. “We’ve lumped together many kinds of brain dysfunction under one name. And in doing so, we’ve overlooked how critical blood vessels—and by extension, nutrition—are to preserving brain function.”
The pathology of Alzheimer’s disease described the abnormal buildup of two proteins in the brain—amyloid and tau—which clump together, forming plaques and tangles which are believed to disrupt brain cell function.
Yet Rosenberg says cerebrovascular disease and small vessel disease, which in some cases are connected to B vitamin deficiency, is more prevalent with cognitive decline and dementia than the buildup of harmful proteins in the brain, which has been the focus of so much research and drug development to treat Alzheimer’s disease. Treating people with drugs meant to address the protein buildup will not work if the cause of dementia symptoms is a B12 deficiency…
To pinpoint a B12 deficiency requires two additional tests. One, called the MMA test, measures levels of methymalonic acid, an acid produced during certain aspects of metabolism requiring adequate B12. “It can be elevated with even a mild B12 deficiency, indicating a potential higher risk of dementia,” says Jacques.
A second test measures levels of an amino acid, homocysteine, which is also a byproduct of metabolism requiring B12. If only homocysteine levels are elevated, a folate deficiency may be the problem. If both MMA and homocysteine are high, a B12 deficiency is the likely culprit.
If a patient presents with neurological issues or signs of dementia, conducting all three tests will narrow down if a B vitamin deficiency is involved—and which B vitamin it is.
“Unlike changes that we are unable to see in patients being given expensive anti-amyloid antibody drugs to treat Alzheimer’s disease, there is actually evidence that fairly early in the course of cognitive decline we can slow the process if the underlying cause is elevated homocysteine or B12-related deficiency,” says Rosenberg. “It’s my recommendation that patients, with or without anemia, should be screened for elevated homocysteine or B12deficiency because that may be one of the reversible factors in their cognitive decline.”
This isn’t a new theory. Two decades ago, studies like the Framingham Heart Study showed that elevated homocysteine predicted brain atrophy and a higher risk of dementia. More recently, trials such as VITACOG and FACT have shown that B vitamin supplementation can slow brain shrinkage and improve cognitive performance in those at risk.
“There is an enormous amount of education needed around this issue,” Rosenberg says. “We hope to convince cardiologists, neurologists, and internists to measure B12 and homocysteine levels as part of the evaluation of cognitive impairment. Even the modest effects from vitamins that cost pennies a day can be very meaningful in those who will benefit, especially when you compare vitamin supplementation to costly drugs that are getting much more attention yet may have the same or even less benefit.”
B12 and Dementia
Jacques and colleagues currently are leading a study using data from about 2,500 middle-aged and older adults in the Framingham Heart Study, all of whom were free of dementia in the 1990s and all of whom received B12, MMA, and homocysteine testing for the last 20+ years…
Jacques is also looking at the role folate (B9) may play in the development of cognitive issues, specifically the influence high levels of folate might have on B12 and cognitive health.
In the 1950s, people with anemia were treated with folic acid, the synthetic form of folate. Unfortunately, it became clear that while pharmaceutical level treatment with folic acid alleviated anemia, it often masked or exacerbated B12 deficiency. “Scientists observed that people with low B12 and high folic acid concentrations tended to have cognitive issues,” Jacques says.
More recent research suggested that it wasn’t total B12 concentrations that folic acid might be affecting, but perhaps just one component, holoTC, which is the form of vitamin B12 that is crucial for transporting and using B12in cells and is considered a potentially better indicator of vitamin B12 status…
Heart Disease, Cholesterol, and Stroke
B vitamins have also stirred excitement among researchers because of their possible role in heart disease and stroke prevention, but thus far their utility as a clinical treatment remains limited.
Scientists discovered in the early 2000s that riboflavin (B2) could decrease blood pressure very effectively. It is believed that riboflavin improves a biochemical reaction mediated by a gene called MTHFR (methylenetetrahydrofolate reductase) that helps the body use folate. Riboflavin is only effective in reducing blood pressure specifically in patients with the MTHFR 677 TT genotype, however.
Vitamins B6, B12, and folate help the body rid itself of homocysteine, which in overabundance had been linked to an increased risk of heart attacks and strokes, as well as dementia. However, a number of clinical trials in the 1980s showed that B6, B12, and folate supplementation didn’t decrease heart attacks, but did slightly lower the risk of strokes.
Niacin (B3) can lower LDL (the so-called “bad cholesterol”) and raise HDL (the so-called “good cholesterol”). “But it has to be taken in such large doses that it often causes very uncomfortable flushing, like hot flashes,” says Mason. “People often can’t tolerate taking it, and other drug options are available that lower blood LDL that do not have such unpleasant side effects.”
Chronic Inflammation and B6
Perhaps most promising for the future is the role vitamin B6 may play in curbing inflammation, which has been identified as an underlying feature of many chronic diseases, from heart disease to diabetes to arthritis to dementia.
A number of animal studies, plus some human studies, suggest that supplemental B6 can reduce inflammation. “Again, we are talking about giving B vitamins at an appropriate pharmaceutical level under the care of a clinician,” cautions Mason. “B6 can be toxic in large amounts.” He sees this research as an area to watch in the years ahead.”
