intake without additional folic acid supplementation.

Methylcobalamin is the preferred form of Vitamin B12
if cyanocobalamin is not tolerated. However, although
relatively rare, side effects are possible with all forms.

Pernicious anemia (long-term, very high intake),
severe fatigue, depression, headaches, skin rash,
shortness of breath, nausea, increased Vitamin B12
requirements.

General recommendations for nutritional supplementation: To avoid stomach problems and improve tolerance,
supplements should be taken earlier, or in the middle of a larger meal. When taken on an empty stomach or
after a meal, there is a greater risk of some tablets causing irritation, or eventually erosion of the esophageal
sphincter, resulting in Gastroesophageal Reflux Disease (GERD). It is also advisable not to lie down right after
taking pills. When taking a large daily amount of a single nutrient, it is better to split it up into smaller doses
to not interfere with the absorption of other nutrients in food, or nutrients supplemented at lower amounts.
