What I find interesting is that ALL of these test subjects would have tested b12 deficient in Japan.
Japan gives anyone with a b12 serum level lower than 500 a b12 supp to take. Japan has one of the lowest rates of dementia in the world.
I give myself b12 injections just as all my cycling mates do. Im the only vegan. I keep my levels between 800-1450 via monthly 1000mcg hydroxycobalamin shots. No probs.
Read the book 'could it be b12?' if you are interested more in the subject. So many people develop b12 deficiency in western nations due to ill health, pollution, excess stress etc.
I used to think b12 deficiency was a vegan thing until I asked my carcass eating mates to get their levels checked and some came up low serum b12 and with elevated homocysteine.

While we will agree that the methyl form is better, it can also be harder to find. Most pharmacies carry the cyano form since it is cheaper and more stable.
Thankfully, concern about cyanide from a cyanocobalamin supplement really only applies to people with compromised kidney function. See this website for more detail: http://www.veganhealth.org/b12/nocyano
Quote: "While being a natural chemical produced in the body, cyanide is toxic, and the body turns it into thiocyanate in order to excrete it. If this pathway is defective or overwhelmed through ingestion of too much cyanide (such as in smokers, or people in Nigeria who eat large amounts of cassava which is high in cyanide)... a different form of B12 should be given... "
So when the methyl form is available, great! However, for those of us who are non-smokers, rarely eat cassava, and have a healthy detoxification system, taking the cyano form is still a whole lot better than not taking any B12.
Jack Norris RD has responded directly to the comments made by Doug Graham, here:
of course pharmacies sell junk. LEF.org, mercola.com and vitacost.com is my preference for buying quality with value, the NSI brand. Why take Vitamin D2 and make your body convert it to D3, why take B12 as cyanocobalimin and make your body convert it it. Plus, you want a Methyl donor.
Just like you want sulfates.... Thus Glucosamine Hydroxide is junk, while Glucosamine Sulfate is what u want. MSM is Methylsulfonylmethane. Taken at 4,000 per day it is effective.
I notice NOTHING with garbage B-complex sold by the masses. When i take a B-complex from Vitacost.com 3 times a day, i don't need caffeine at all.
best of health.
Kidneys are NOT detected as impaired unless the nephrons are only working below 20% , less why in the world take your chances. Stop buying the Walmart and other store junk. You are not saving any money, spending more.... for garbage vitamins.
Plus, you need HCL to absorb your vitamins. If you on on a acid blocker, you are not going to absorb much. You really want to take apple cider vinegar with your vitamins.
