    • I have a lot to say about this because I think it’s critically important, simple, and it’s a tragedy so few people know.

      First, few people know that vitamins generally reduce our life expectancy. The science on that is well established but, as with most things, marketing is far more effective than science in public opinion.

      B12 is different. It’s from bacteria in soil and before the age of sterilization everyone got enough. Animals are simply carriers. They get it from unsterile conditions or supplementation.

      Estimates vary, but what’s clear is a significant portion of the population is deficient, especially as you get past 50 and your ability to absorb goes down. By age 80, you probably need B12 shots in the butt or risk neuropathy. Neuropathy causes the elderly to lose their balance. It’s not reversible and is responsible for many a broken hip. Tragic, because B12 supplementation is relatively easy. Even Madonna administers B12 pricks (shots) into the butts of her dancers.

      The paper you referenced from the team in Milan was extremely well written, imo. I read it very carefully. My only concern is it (by design) eliminated people who have trouble maintaining B12 levels because of illness or age. That’s a lot of people who really need it.

    • I ran out of the B12 lozenges in the bottle from Jarrow Formulas and got a new one on Amazon. But then I wondered if I should just get a Costco "Kirkland" branded B12.

      Kirkland Signature has 300 quick dissolve tablets vs 60 lozenges with the same amount of B12 - 5000 mcg. They are also "cherry" flavored, which was a big deal for me. 😀

      Turns out not all "cherry" flavors are made the same. Kirland's uses sucralose to make the tablets sweet and to my taste it didn't go well. I'll keep the bottle as a backup, but will go back to Jarrow Formulas brand again. I shouldn't be that picky about vitamins, but oh well.
