As vegans, we need B-12 supplementation.
The linked study shows excess B-12 causes excess death in all demographics. Most supplements out there are way more than your RDA often like 200x or more. Despite the claims that because it is water soluble, it it non-toxic, it still is known to cause toxicity. It is stored in your liver for years and high circulating blood levels can cause cobalamin toxicity.
Just like years ago we found out about B9 (as folic acid) toxicity and birth defects, then B6 toxicity, which is now making news and finally being regulated. These cause the same symptoms at B12 toxicity, of which we are beginning to see more studies. Even those all these B vitamins are are water-soluble and we were told not to worry, they can all cause toxicity.
Here is another study showing excess B6 and/or B12 leads to increase incidence of hip fracture in post-menopausal women: https://pubmed.ncbi.nlm.nih.gov/31074816/.
What I wish someone would have told me: While taking a B12 supplement, If you are experiencing excessive flushing, restlessness, muscle spasms and tingling in the hands in the feet (that is neuropathy and nerve damage is irreversible), consider the possibility of your B12 intake causing toxicity, especially if you take high doses regularly. Some bodies are more prone to it than others.
Stay healthy friends. <3
Many moons ago, like 2010, after being vegan for a few years I got my blood tested and found b-12 deficiency (I wasn’t consuming flax or supplements.)
I hit the B vitamins pretty hard :-/ Thankfully I’ve since relaxed. Hope I don’t keel over
That is right, I eat a little of Flax Seeds powder on everything.
I live with a roommate who life will be ending in years from now, so gets sick easily, every Jan.’s cold weather, he gets sick & thus I do too. One-year, even after COVID-19 & it’s Variants epidemic was finished he got COVID-19 & it’s Variants, for the fourth time! I was so scared to not catch COVID-19 & it’s Variants in my chest, from him, I was still masking & gloving, always did washing my hands a lot, roommate has terrible hygiene. When I started feeling like fighting something, I started eating a super amount of Tutmeric. So much so that I went to a free clinic, I was pooping blood & had DuckDuckGoed it & found-out too much is bad for intestins (SP?), doctor said is possible, but needed money to test for it, I could not afford it so never did it. Did go back to only dust everything Ineat with Turmeric powder.
