How They Work Oral supplements rely on your digestive system for absorption
Plant-based diets lack Vitamin B12, increasing the risk for individuals who don't consume animal products
We think its worth the tradeoff
High-dose oral therapy (10002000 micrograms daily) can be effective even in pernicious anaemia, as approximately 1% of B12 is absorbed through passive diffusion independent of intrinsic factor
Many studies have found a high prevalence of elevated homocysteine among vegans who dont supplement with B12
