Something pink? Something with extra Vitamin B? Vitamin B12? B13? Just the number of things with different types of Vitamin B in them was an embarrassment of choice itself. There were powders as well as oils, tubes of gel, even packets of some kind of pungent -smelling seed that was meant to be good for some obscure part of you in some arcane way.
Douglas Adams (The Long Dark Tea-Time of the Soul (Dirk Gently, #2))
There is a very strange and undetectable sickness in the modern population that responds to huge doses of vitamin B12.
Steven Magee
But nutrition affects BDNF, too. Eating a diet high in sugar decreases BDNF. Eating foods with folate, vitamin B12, and omega-3 fats increases BDNF in the brain, just as exercise does.
John J. Ratey (Go Wild: Eat Fat, Run Free, Be Social, and Follow Evolution's Other Rules for Total Health and Well-Being)
Low amounts of vitamin B12 with normal folate levels may cause cognitive impairment and anemia, while high amounts of folate and normal vitamin B12 levels may improve cognitive function (132).
Orrin Devinsky (Alternative Therapies For Epilepsy)
This vitamin cannot be produced by higher plants (the ones that yield our fruits and vegetables), but like vitamin K, vitamin B12 is made by beneficial bacteria living in the small intestine. Meat, fish, poultry, milk products, and eggs are good sources of vitamin B12. Grains don’t naturally contain vitamin B12, but like other B vitamins, it’s
Carol Ann Rinzler (Nutrition for Dummies)
Other elements are critical not for creating life but for sustaining it. We need iron to manufacture hemoglobin, and without it we would die. Cobalt is necessary for the creation of vitamin B12. Potassium and a very little sodium are literally good for your nerves. Molybdenum, manganese, and vanadium help to keep your enzymes purring. Zinc—bless it—oxidizes alcohol.
Bill Bryson (A Short History of Nearly Everything)
Healing Foods When you’re looking to boost the immune system and support the reproductive system, the best foods to concentrate on are wild blueberries, sesame tahini, avocados, black beans, asparagus, apples, spinach, black grapes, and cucumbers. They’ll help by variously providing antioxidants, preventing hot flashes, providing critical nutrients to fortify vital organs, reducing inflammation, and keeping hormone levels balanced. Herbs and Supplements to Address General Symptoms Silver hydrosol: kills viruses, bacteria, and other microbes on contact and supports the immune system. Zinc: kills viruses, boosts the immune system, and helps protect the endocrine system. Licorice root: aids the adrenal glands and helps balance the body’s levels of cortisol and cortisone. L-lysine: impairs the ability of virus cells to move and reproduce. Vitamin B12 (as methylcobalamin and/or adenosylcobalamin): strengthens the central nervous system. Nascent iodine: stabilizes and strengthens the thyroid and the rest of the endocrine system. Ashwagandha: fortifies the adrenal glands and helps balance the production of cortisol.

Not only did the selection of chicken as the dominant meat source have no basis in the history of the Mediterranean diet, but one could reasonably question whether chicken has the same effect on health as do Cretan goats or kids or lamb. Red meat, for example, has a far greater abundance of vitamins B12 and B6, as well as the nutrients selenium, thiamine, riboflavin, and iron, than does chicken.
Nina Teicholz (The Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy Diet)
While a gluten-free diet may help alleviate symptoms in some people, for others it can lead to nutritional problems. Gluten-free products are typically lacking in vitamin B12, folate, zinc, magnesium, selenium and calcium. Other studies found that gluten-free diets in Spain contained on average more fat and less fibre than comparable diets. It is clear that excluding an entire food group from your diet can reduce fibre and dietary diversity, which also affects our gut microbes, creating the possibility of long-term adverse effects.
Tim Spector (Spoon-Fed: Why Almost Everything We’ve Been Told About Food is Wrong)
Apple and apricot seeds contain a vitamin called B12, which I found to be illegal to sell in pharmacies. Now, this is very interesting. You can buy all kind of vitamins in pharmacies, but not B12. Why in the hell would the pharmaceutical industry make a vitamin that we can eat on our own, through seeds, illegal? I asked this question to employees in the pharmacies and many doctors, and they couldn't answer. They just kept looking at me as if I was trying to get ingredients to make my own synthetic drugs. For most people, what is illegal is really illegal. Most people are too stupid to think for themselves, even when my question is so obvious that they seem to have brain damage not to realize the relevance of such question.

He shared his place with a Dr. Tubeside, whose practice consisted largely of injecting people with "vitamin B12", a euphemism for the physician's own blend of amphetamines. Today, early as it was, Doc still had to edge his way past a line of "B12"- deficient housewives of a certain melancholy index, actors with casting calls to show up at, deeply tanned geezers looking ahead to an active day of schmoozing in the sun, stewardii just off in some high-stress red-eye, even a few legit cases of pernicious anemia or vegetarian pregnancy, all shuffling along half asleep, chain-smoking, talking to themselves, sliding one by one into the lobby of the little cinder-block building through a turnstile, next to which, holding a clipboard and checking them in, stood Petunia Leeway, a stunner in a starched cap and micro-length medical outfit, not so much an actual nurse uniform as a lascivious commentary on one, which Dr. Tubeside claimed to've bought a truckload of from Fredericks's of Hollywood, in a variety of fashion pastels, today's being aqua, at close to wholesale.

REPROGRAMMING MY BIOCHEMISTRY A common attitude is that taking substances other than food, such as supplements and medications, should be a last resort, something one takes only to address overt problems. Terry and I believe strongly that this is a bad strategy, particularly as one approaches middle age and beyond. Our philosophy is to embrace the unique opportunity we have at this time and place to expand our longevity and human potential. In keeping with this health philosophy, I am very active in reprogramming my biochemistry. Overall, I am quite satisfied with the dozens of blood levels I routinely test. My biochemical profile has steadily improved during the years that I have done this. For boosting antioxidant levels and for general health, I take a comprehensive vitamin-and-mineral combination, alpha lipoic acid, coenzyme Q10, grapeseed extract, resveratrol, bilberry extract, lycopene, silymarin (milk thistle), conjugated linoleic acid, lecithin, evening primrose oil (omega-6 essential fatty acids), n-acetyl-cysteine, ginger, garlic, l-carnitine, pyridoxal-5-phosphate, and echinacea. I also take Chinese herbs prescribed by Dr. Glenn Rothfeld. For reducing insulin resistance and overcoming my type 2 diabetes, I take chromium, metformin (a powerful anti-aging medication that decreases insulin resistance and which we recommend everyone over 50 consider taking), and gymnema sylvestra. To improve LDL and HDL cholesterol levels, I take policosanol, gugulipid, plant sterols, niacin, oat bran, grapefruit powder, psyllium, lecithin, and Lipitor. To improve blood vessel health, I take arginine, trimethylglycine, and choline. To decrease blood viscosity, I take a daily baby aspirin and lumbrokinase, a natural anti-fibrinolytic agent. Although my CRP (the screening test for inflammation in the body) is very low, I reduce inflammation by taking EPA/DHA (omega-3 essential fatty acids) and curcumin. I have dramatically reduced my homocysteine level by taking folic acid, B6, and trimethylglycine (TMG), and intrinsic factor to improve methylation. I have a B12 shot once a week and take a daily B12 sublingual. Several of my intravenous therapies improve my body’s detoxification: weekly EDTA (for chelating heavy metals, a major source of aging) and monthly DMPS (to chelate mercury). I also take n-acetyl-l-carnitine orally. I take weekly intravenous vitamins and alpha lipoic acid to boost antioxidants. I do a weekly glutathione IV to boost liver health. Perhaps the most important intravenous therapy I do is a weekly phosphatidylcholine (PtC) IV, which rejuvenates all of the body’s tissues by restoring youthful cell membranes. I also take PtC orally each day, and I supplement my hormone levels with DHEA and testosterone. I take I-3-C (indole-3-carbinol), chrysin, nettle, ginger, and herbs to reduce conversion of testosterone into estrogen. I take a saw palmetto complex for prostate health. For stress management, I take l-theonine (the calming substance in green tea), beta sitosterol, phosphatidylserine, and green tea supplements, in addition to drinking 8 to 10 cups of green tea itself. At bedtime, to aid with sleep, I take GABA (a gentle, calming neuro-transmitter) and sublingual melatonin. For brain health, I take acetyl-l-carnitine, vinpocetine, phosphatidylserine, ginkgo biloba, glycerylphosphorylcholine, nextrutine, and quercetin. For eye health, I take lutein and bilberry extract. For skin health, I use an antioxidant skin cream on my face, neck, and hands each day. For digestive health, I take betaine HCL, pepsin, gentian root, peppermint, acidophilus bifodobacter, fructooligosaccharides, fish proteins, l-glutamine, and n-acetyl-d-glucosamine. To inhibit the creation of advanced glycosylated end products (AGEs), a key aging process, I take n-acetyl-carnitine, carnosine, alpha lipoic acid, and quercetin.

However, Pauling’s interest in these carotenoids and flavonoids was confined to their chemical structures and the influence of structure on optical properties; he did not address their health functions. In 1941 Pauling was diagnosed with Bright’s disease, or glomerulonephritis, which was at the time an often-fatal kidney disorder. On the advice of physicians at the Rockefeller Institute, he went to San Francisco for treatment by Thomas Addis, an innovative Stanford nephrologist. Addis prescribed a diet low in salt and protein, plenty of water, and supplementary vitamins and minerals that Pauling followed for nearly 14 years and completely recovered. This was dramatic firsthand experience of the therapeutic value of the diet. Revelations When Pauling cast about for a new research direction in the 1950s, he realized that mental illness was a significant public health problem that had not been sufficiently addressed by scientists. Perhaps his mother’s megaloblastic madness and premature death caused by B12 deficiency underlay this interest. At about this time, Pauling’s eldest son, Linus Jr., began a residency in psychiatry, which undoubtedly prompted Pauling to consider the nature of mental illness. Thanks to funding from the Ford Foundation, Pauling investigated the role of enzymes in brain function but made little progress. When he came across a copy of Niacin Therapy in Psychiatry (1962) by Abram Hoffer in 1965, Pauling was astonished to learn that simple substances needed in minute amounts to prevent deficiency diseases could have therapeutic application in unrelated diseases when given in very large amounts. This serendipitous and key event was critically responsible for Pauling’s seminal paper in his emergent medical field. Later, Pauling was especially excited by Hoffer’s observations on the survival of patients with advanced cancer who responded well to his micronutrient and dietary regimen, originally formulated to help schizophrenics manage their illness.19,20 The regimen includes large doses of B vitamins, vitamin C, vitamin E, beta-carotene, selenium, zinc, and other micronutrients. About 40 percent of patients treated adjunctively with Hoffer’s regimen lived, on average, five or more years, and about 60 percent survived four times longer than controls. These results were even better than those achieved by Scottish surgeon Ewan Cameron, Pauling’s close clinical collaborator, in Scotland. After a long and extremely productive career at Caltech,

I still opt for a scoop of plant-based protein powder from time to time—after a particularly brutal workout, if I’m feeling overly fatigued from training, or when I know I haven’t sourced quite enough whole food protein from my meals. I prefer to combine a variety of plant-based proteins for this purpose, such as hemp, pea, and sprouted brown rice, to ensure maximum bioavailability and assimilation of all the essential amino acids our bodies can’t produce themselves. In fact, I recently formulated my own plant-based protein recovery supplement, in cooperation with microbiologist Compton Rom of Ascended Health, called Jai Repair. Infused with a proprietary blend of additional reparative nutrients like Cordyceps mushroom extracts, L-glutamine, vitamin B12, and antioxidants such as resveratrol, Jai Repair is scientifically devised to enhance rapid recovery from exercise-induced stress and is a formula I’ve come to rely on as a key component in my training regime.

The only nutrients lacking in a vegan diet are vitamin B 12 and the long-chain omega-3 fatty acids EPA and DHA. One should also consider supplementation with iodine and vitamin D, depending on one’s exposure to sunshine and consumption of seaweed for iodine. The amount of zinc might be somewhat suboptimal with a vegan diet because of zinc binding by phytates in plants, but otherwise, animal products don’t provide anything that you can’t get in a safer package—from consuming plant foods. So eat less animal products—consider hardly eating them at all—for the best health and then supplement wisely and conservatively to make up for any insufficiencies.

Vegans following a whole food diet had a borderline supply of vitamin B12. Folic acid, vitamin B6, TSH, iron metabolism, and the blood count were in the normal range. Vegans taking dietary supplements demonstrated satisfactory overall results. An ingestion of sundried mushrooms can contribute to the supply of vitamin D.

Pernicious Anemia translates into fatal blood deficiency, as a century ago it killed many of the people that developed it. It was a horrible and prolonged death process. It was later discovered that feeding raw liver to the patients would treat it. Today the condition is treated with vitamin B12 and iron supplements.

Vitamin B vitamins have long been seen as a great supplement to lower anxiety levels. Vitamins B6 (pyridoxine), B1 (thiamine) and B12 (cobalamin) have been seen as particularly effective. I personally take a B-Complex vitamin each night which I feel has given me extra energy. You can also get Vitamin B from a number of food sources, from turkey and tuna, to lentils and beans.
