The combined effect is faster, better-supplied tissue repair across muscle, tendon, and other soft tissue
Normal prenatal vitamins may not have enough of this nutrient to make up for a complete lack of it in the diet.
Age can also play a role, as stomach acid production often decreases in older individuals
Unlike most nutrients, absorption of vitamin B12 actually begins in the mouth where small amounts of unbound crystalline B12 can be absorbed through the mucosa membrane [16] Food protein bound vitamin B12 is digested in the stomach by proteolytic gastric enzymes, which require an acid pH (Even small amounts of B12 taken in supplements bypasses these steps, and thus, any need for gastric acid, which may be blocked by antacid drugs)
according to the National Academies of Sciences, Engineering, and Medicine, absorption is approximately 50% at 1 mcg but falls to roughly 1.3% at 1,000 mcg
