Vitamin B12 Dietary Supplements

If for some reason you are not able to include the above vitamin b12 for vegetarian foods, the next best option will be dietary supplements. These supplements are available in the form of tablets or self-dissolving strips.

Those who consume a plant-based diet may require extra vitamin B12 in the form of supplements, particularly if they are expecting or nursing. In addition, those who are elderly, have digestive issues or are using certain drugs such as proton pump inhibitors and metformin, may need to take a supplement.

Between around 56% of a dose of 1 mcg and 5% of a dose of 1,000 mcg, vitamin B12 can be absorbed differently. So, if someone takes vitamin B12 less regularly, they will need to take more of it overall to get the same amount of vitamin B12 absorbed.
