While we commonly hear that low stomach acid can cause b12 deficiency, what I hear less about is that having a b12 deficiency being able low stomach acid. What is everybody's thought on this? It's somewhat of a chicken vs egg thing here.
As for me being a long time strict vegan (and doubt PA sufferer), I believe it's possible that after years of no reliable source of b12, I became deficient. After years of being b12 deficient, my body became unable to create adequate amounts of stomach acid which has hampered my digestion causing bloating and digestion issues.
I'm hoping that after long term b12 supplementation, my stomach acid levels will rise and improve my digestion.
Has anybody seen any evidence of low b12 causing low stomach acid and having treatment reverse the low acid?
Thank you for any input
