Can I take Folic acid and Vitamin D together?

Why this happens

Folic acid and Vitamin D are processed by the body through different pathways. They do not compete for absorption in the gut, nor do they interfere with how each other is broken down or used by the body's cells.

What you should do

It is safe to take folic acid and Vitamin D at the same time. Always follow the dosage instructions on the packaging or those provided by your healthcare professional.

Important precautions

Vitamin B12 deficiency (Pernicious Anaemia)

Folic acid can mask the symptoms of vitamin B12 deficiency. If you have B12 deficiency, taking folic acid alone can allow serious nerve damage to progress even though your blood count appears normal. Your doctor must ensure your B12 levels are checked before or during treatment.

Hypercalcaemia (high blood calcium levels)

Do not take vitamin D supplements if you have high levels of calcium in your blood or urine, as this can lead to serious kidney damage and heart rhythm problems.

Food and drink warnings

Alcohol

It is best to avoid or strictly limit alcohol while taking folic acid. Alcohol interferes with the way your body absorbs and uses folic acid, which can make the treatment less effective. Chronic alcohol consumption is a common cause of folate deficiency.

It is best to avoid or strictly limit alcohol when taking Vitamin D. Long-term or excessive alcohol consumption can interfere with how your body absorbs and processes Vitamin D, making the supplement less effective.

High-fat meals

Vitamin D is a fat-soluble vitamin. It is best absorbed by your body when taken with a meal that contains some fat (such as eggs, avocado, nuts, or dairy).
