Fatigue rarely comes from a single cause, but nutrient status deserves more attention than it usually gets. A 2026 study in Nutrients measured homocysteine, an amino acid that rises when B12 and folate are low, in 602 adults and compared it with fatigue and motivation. Higher homocysteine levels were associated with greater physical fatigue in men and lower motivation in women, even after accounting for sleep, exercise, and other factors. The associations were modest and exploratory, and this kind of cross-sectional study cannot prove cause and effect. Still, the biology is well established. B12 and folate are essential cofactors in methylation, the one-carbon cycle that clears homocysteine and supports the production of neurotransmitters like dopamine and serotonin. When that cycle runs poorly, energy and mood can suffer. I have written and spoken about methylation as an underappreciated driver of fatigue for many years, so this finding did not surprise me. It is a useful reminder that if fatigue is a primary symptom, optimizing methylation status is worth attention. The forms matter here, since methylated B12 (methylcobalamin) and folate (5-MTHF) are more readily used by the body than the synthetic versions in many supplements.

Vitamin E is the collective name for a group of fat soluble nutrients that function as antioxidants to protect cells and tissues. Antioxidants protect cells from free radical damage. Sounds like a sci-fi movie but actually free radicals are all around us (and we even create some ourselves). Free radicals are unstable molecules that damage cells, some well known examples we’ve likely all had exposure to include: - UV rays - Exercise - Cigarette smoke - Environmental pollution - Standard American Diet (SAD) - Alcohol #1 Helps reduce oxidative stress Antioxidants are substances that protect cells from the damaging effects of free radicals, in our environment or produced endogenously. Free radicals are unstable molecules that contain an unshared electron. Free radicals damage cells and might contribute to the development of cardiovascular disease and cancer. Sources of free radicals include those produced internally through physiologic stress like exercise and also environmental exposures including cigarette smoke (first and second hand), UV rays from the sun and pollution. Vitamin E is a free radical scavenger, essentially diffusing the dangerous capabilities of free radicals and protecting cells in the process. Because free radicals have the capability to damage cell membranes, proteins and nucleic acids, they can contribute to cancer risk. Take for example free radicals from UV rays causing skin cancer. Antioxidants including vitamin e, vitamin c and selenium may therefore play a role in cancer prevention and other chronic illness associated with free radical damage. #2 Boosts Immune Function Not only does vitamin E protect cells against damage but it also helps regulate immune function. Vitamin E is involved in regulation of gene expression and cell signalling. Because of its role in immune function, it is found in higher concentrations in immune cells compare to other cells. In fact, research shows it is one of the most effective nutrients that keeps the immune system running smoothly.

Black cumin seeds and black seed oil from those seeds is a phenomenon in nature that has been studied for hundreds of years due to its health properties. It’s Latin name is Nigella sativa, and a search in PubMed will result in over 2500 articles published. Nigella sativa is known by various other names such as: black caraway, fennel flower, nutmeg flower, Roman coriander, kaljeera, habbat al-barakah, among others. Relatively unknown in the U.S. until recent times, it has a long history of use in the Middle East. Black Seed Oil Cures Many Cancers According to Numerous Studies Study: Black Seed Oil Relieves Pain Associated with Arthritis New Research: Black Seed Oil Effective in Treating Alzheimer’s and Ischemia Organ Damage Research: Black Seed Oil Protects Pancreas Damage from Diabetes – Helps Heal Wounds Study: Black Seed Oil Helps Parkinson’s – Can be Used for Anti-depressant and Anti-anxiety Treatment We are starting to understand how this seed can help with so many diseases!

A landmark clinical study with over 1,000 participants reveals the dose-dependent power of nattokinase to shrink arterial plaque, improve lipid profiles, and do it all without side effects. Atherosclerosis and the Limits of Mainstream Medicine Atherosclerosis--the progressive narrowing of the arteries due to plaque buildup--is a leading cause of heart attacks and strokes. For decades, mainstream medicine has leaned heavily on statins and surgical interventions, but these approaches often address symptoms rather than root causes. Worse yet, many patients experience significant side effects from long-term statin use, including muscle pain, liver damage, and increased risk of diabetes. The hunt for a safer, natural solution has brought attention to nattokinase (NK)--a fibrinolytic enzyme derived from fermented soybeans (natto). Long valued in traditional Japanese medicine, NK is now under scientific scrutiny for its potential to dissolve blood clots, reduce blood pressure, and reverse plaque accumulation. The Study: Real-World Evidence in 1,062 Participants Published in Frontiers in Cardiovascular Medicine, this large-scale clinical study evaluated the effects of nattokinase on atherosclerosis progression and hyperlipidemia over 12 months. Participants took either 10,800 FU (fibrinolytic units) or 3,600 FU per day. The findings were nothing short of remarkable: - At 10,800 FU/day, NK led to a significant reduction in the thickness of the carotid artery intima-media and the size of carotid plaques. - Plaque regression rates ranged from 66.5% to 95.4% depending on individual factors. - No adverse effects were reported at this high dose. Conversely, participants taking 3,600 FU/day saw no significant improvement--clearly indicating that the commonly recommended dose may be too low to be effective. This research strikes at the heart of cardiovascular disease mortality. Unlike statin drugs, which aim to suppress LDL levels without addressing arterial integrity or clot risk, nattokinase directly targets the fibrin matrix and plaque structures responsible for occlusion. It represents a root-cause approach--something sorely missing in modern pharmaceutical paradigms.

I've argued for years that the threshold for B12 deficiency is set too low, and new research from the Annals of Neurology makes that case more forcefully than ever. Researchers at UCSF enrolled 231 healthy older adults with B12 levels considered entirely normal by current standards and found that participants with lower levels of the form of B12 your cells can actually absorb and use (called holotranscobalamin) showed slower nerve signaling in the visual pathway, slower cognitive processing that became more pronounced with age, and more areas of white matter damage visible on brain MRI. Neurological changes were measurable at levels the medical system considers acceptable. The current US deficiency cutoff was not based on clinical outcomes; it was calculated as a statistical threshold using population averages. In my clinical practice, I saw this pattern repeatedly: patients with cognitive and neurological complaints whose primary care doctors had reassured them their B12 was "normal," but whose homocysteine, holotranscobalamin, and methylmalonic acid levels told a very different story. Those functional markers reveal whether B12 is actually reaching cells and being used, and very few physicians test for them. In addition, for people who eat a lot meat and animal products, their B12 levels tend to be higher above 2000. There is not issue at all with levels that high. Actually, this new study support the fact that higher B12 levels is important in the elderly.
