If you have a vitamin B12 deficiency due to dietary reasons, you should take vitamin B12 tablets every day between meals.
Optimizing Vitamin B12 Absorption
The timing of your vitamin B12 supplementation can influence its absorption. Here's a more detailed breakdown:
-
Between Meals: The reference specifically suggests taking B12 between meals. This can be helpful because some foods and medications can interfere with B12 absorption. Taking it on an empty stomach (or close to it) may improve absorption.
-
Frequency: Consistency is key. Taking vitamin B12 daily is generally recommended for dietary deficiencies to maintain adequate levels.
-
Form Matters: Consider the form of B12 supplement you're taking. Cyanocobalamin is a common form, while methylcobalamin is another. Some people find methylcobalamin easier to absorb and utilize. Discuss with your doctor or pharmacist which form is best for you.
-
If Receiving B12 Injections: If you are receiving B12 injections due to a severe deficiency or absorption issues, the timing of oral supplements is less critical, but maintaining a consistent daily schedule is still beneficial. Your doctor will determine the injection schedule.
Factors Affecting B12 Absorption
Several factors can affect how well your body absorbs vitamin B12:
-
Dietary Intake: A diet lacking in animal products (meat, poultry, fish, eggs, dairy) is a common cause of B12 deficiency.
-
Medical Conditions: Certain conditions, such as pernicious anemia, Crohn's disease, celiac disease, and atrophic gastritis, can impair B12 absorption.
-
Medications: Some medications, like metformin (for diabetes) and proton pump inhibitors (PPIs) used to reduce stomach acid, can interfere with B12 absorption.
-
Age: As you age, your body's ability to absorb B12 from food may decrease.
Consulting a Healthcare Professional
It's always best to consult with a doctor or registered dietitian to determine the appropriate dosage and timing of vitamin B12 supplements, especially if you have any underlying health conditions or are taking other medications. They can assess your individual needs and provide personalized recommendations.
