Less Frequent Dosing: Instead of a daily pill, injections are typically given on a weekly or monthly schedule as determined by a healthcare provider
How frequently should I get Vitamin B12 shots for optimal results
And of the few that exist (less than 10), they are either done in cell cultures or in rats
I have been SI B12 for nearly 5 years and got so much stronger considering how terrible and weak I was
Thats because B12 helps your body effectively process fats and carbohydrates, turning them into usable fuel
Supplementation aside, you should always aim to get the majority of your nutrients from food sources, but when it comes to vitamin B12, that's definitely easier said than done, especially for those following plant-based diets free of all animal products
