Vitamin B12 Deficiency and Brain Health

Republished with permission from

One of the most remarkable papers I have read in the psychiatric literature was about a 57 year old woman who was treated with months of both antipsychotic and antidepressant medications and given two rounds of electroconvulsive treatment before anyone bothered to check her vitamin B12 level.

Her symptoms were years in the making including tearfulness, anxiety, movement abnormalities, constipation, lethargy, and eventually perceptual disturbances (hearing her name called) and the ultimate in severe psychiatric pathology: catatonia. Despite her inpatient treatment, she remained suicidal, depressed, and lethargic. (more…)

10 Reasons Why You Need Vitamin B12


Mussels and other shellfish are a great natural source of vitamin B12.
Vitamin B12 is an essential nutrient that keeps the body’s nerve and blood cells healthy. It is involved in the metabolism of every cell in the human body, and is necessary for DNA synthesis and regulation, as well as fatty acid synthesis and energy production. The benefits of vitamin B12 start in the womb, are vital during infancy, and protect you from disease throughout your life.

Not getting enough B12 causes tiredness, weakness, changes in elimination, loss of appetite, and weight loss—all symptoms of megaloblastic anemia, a condition characterized by very large red blood cells. It comes on slowly, especially when compared to that of other types of anemia, so can be hard to diagnose in its early stages. (more…)

Are You Anemic? Going Beyond Iron Supplements

Anemia is broadly understood as a deficiency of red blood cells. The chief role of red blood cells is to grab oxygen from the lungs and deliver it to every nook and cranny in the body. This ensures the survival of our cells.

Anemia is complex, and there is no one mechanism behind it.

When the body is anemic, we feel tired and lethargic. Every tissue in the body needs a steady supply of oxygen in order to have fuel and to function properly. Oxygen is one of the ways that we produce energy.

When we talk about anemia, we are really talking about oxygen not getting to where it needs to be. (more…)

Nori is a high-protein plant source of vitamin B-12

Nori, also known as purple laver or Porphyra yezoensis, may be the most popular seaweed in the United States. Nori is the seaweed most widely used as a wrap for sushi. It is usually sold in large, thin, dried sheets. Traditional Asian cultures have known for centuries of the extremely high mineral content – especially iodine -in all seaweeds. Iodine is essential for proper thyroid function. (more…)

B12 deficiency: a silent epidemic with serious consequences

 B12 deficiency: an invisible epidemic
‘What do all of these diseases have in common?
  • Alzheimer’s, dementia, cognitive decline and memory loss (collectively referred to as “aging”)
  • Multiple sclerosis (MS) and other neurological disorders
  • Mental illness (depression, anxiety, bipolar disorder, psychosis)
  • Cardiovascular disease
  • Learning or developmental disorders in kids
  • Autism spectrum disorder
  • Autoimmune disease and immune dysregulation
  • Cancer
  • Male and female infertility
Answer: they can all mimic the signs and symptoms of vitamin B12 deficiency.’ (more…)

Breaking Down the B’s

There are a variety of B vitamins that have many different benefits, but there isn’t necessarily one that stands out from the rest. “Trying to identify which B vitamin is best is a little like asking a parent of seven who their favorite child is,” said Wright. “The fact is that most B vitamins work together as a system. For instance, there is significant (though controversial) evidence that the B vitamins pyridoxine (B6), folic acid (B9) and cyanocobalamin (B12) work together to reduce the amino acid homocysteine in the blood, which has big implications for heart, brain and circulatory health.” (more…)

Journal commentary suggests flawed studies intentionally obscured benefits of vitamin therapy in preventing strokes

Prior to the release of several studies that claim the therapy is ineffective, taking high doses of B vitamins was considered an effective regimen for lowering homocysteine levels, and thus helping to prevent strokes and cardiovascular disease. But a new commentary published in the Journal of the American Medical Association (JAMA) suggests that these negative studies are flawed, and that B vitamin therapy is still an effective heart protection therapy.

Find health with great-tasting nutritional yeast

Yeast has a long history of use by society dating back as early as the ancient Egyptians and possibly earlier. Yeast was initially used to produce breads and alcohol; it was most likely discovered by accident and considered magical in its process. Not until Pasteur and the advent of the microscope was it determined to be a living organism. Today yeast has many different uses, and fermentation has been adopted across a wide variety of foods to extend shelf live and unlock nutrients from food: nutritional yeast being one of these foods.

B12 Deficiency During Pregnancy Increases Risk for Insulin Resistance in Child

The importance of folic acid during pregnancy is well known. The adequacy of vitamin B12 during pregnancy is also quite important, as vitamin B12 is needed for nervous system health as well as the proper assembly of proteins that make up the physical body of the child. Compromised B12 status during pregnancy is now related to an increased risk for insulin resistance, and thus obesity, in one’s child. (more…)
