So Durianriders and his crew keep on lying about B12 recommendations in Japan… maybe because they never came across someone who could debunk their lies being able to read Japanese. So here’s my contribution to this forum. Proving him wrong… and explaining what’s this Japanese B12 fuss all about.
So Actually Japanese recommendatios of B12 consumption are not that different from Western countries. Japanese Recommend 2.4μg a day as an healthy intakel of B12.
Also we need to bare in mind Japanese levels of B12 will always be high due to the high consumption of Seaweed ( so are mine) but this doesn’t mean all of the B12 is absorbed. Humans won’t absorb most of the B12 that’s ingested with the seaweed. Like protein it’s better absorbed through the consumption of animal products. The only animals that can absorb these properly are usually ruminants and animals ith a digestive system better adapted to plant consumption. So in theory even if you have High levels of B12 in your bloodstream you can suffer from B12 deficiencies due to malabosrbtion. This also happens due to other factors but the main reason in Japan is the fact that part of the B12 comes from seaweed thus even if you have healthy levels in your bloodstream it doesn’t mean you are ingesting the right amounts of absorbable b12.
Also Japanese are very concerned about their health and you can find vitamin/ protein supplements pretty much everywhere… even in 100EN Stores( this doesent mean all of them take supplements but supplements are widely available there… more than in Europe anyways).
So here are the Japanese Links for anyone who can read it ( Proof I’m not lying)
http://ketueki.syanari.com/VB12.html (249～938 pg/ml)
Translation [Vitamin 12 Daily intake for adult man is 2.4μg, adult woman 2.4μg, babies 0.2～0.9μg, primary school students 1.3～1.6μg, teenagers 2.1～2.3μg. There's no maximum intake.]
and if you want to compare here’s a link from livestrong link do Daily recommendations… as you can see they even recommend higher doses for teenagers than in Japan… so next time you’re going to lie… don’t lie about Japan:
Take care and if you have the links/articles that say the Japanese recommend more B12 ingestion than us feel free to share it… I think you might have misread it. Also I believe you might have come across such articles due to the Seaweed Interference but so far doctor recommendations are very similar to western recommendations and do not take into account their seaweed consumptionB12-Levels in Japan (Debunking DR and other 811 lies about it), 100% based on 4 ratings
