ImpactModerate impact

Abstract in brief

The study investigates whether high levels of vitamin B12 in the blood are linked to an increased risk of lung cancer, using both observational data and genetic approaches.
Results showed that higher circulating vitamin B12 levels are associated with a greater risk of developing lung cancer, with a dose-response relationship indicating that as B12 levels double, the risk increases.
The findings from both the blood measurements and genetic analysis support the idea that having high vitamin B12 levels might contribute to the development of lung cancer.]

@JonScoff @Heymrposti91842 @Theres2ManyLies @EcoNews2021 @Veganella_ All bacteria in the rhizosphere produce B12. I took too much B12 it seems as my homocysteine levels were too high. I reduced my daily dose. https://t.co/uwFoot4CQ0

@HayraUslu Evet, üstelik doz çok da yüksek sayılmaz. Sigara içmeyenlerde dahi günlük tavsiye edilen miktarın iki katının alınması, akciğer CA riskini 15% artırıyor. https://t.co/E1VdM7gbUp https://t.co/G43xdobJnP

@fp3yoshi そのようです。過剰な摂取が問題に。VB12 がんで検索すると食道がんより肺がんリスクに関する情報が多く見つかりますね。。。Pubmedにもこういう論文があり、結論ではCirculated VB12が肺がんリスクを高めるとあります。　https://t.co/bWpY1ZSK7u

@ChrisMasterjohn @sraosha @jenni_mcconnell https://t.co/1uiVFIwhKv I didn't believe it when it was just cohorts without MR, but with MR and controlling for smoking as a confounder I'm scratching my head. This may be a reason to take cyano over other forms (easier get normal, non-high B12 levels while keeping MMA low).
