Can I take Vitamin B2 and Vitamin D together?

Why this happens

Vitamin B2 and vitamin D are processed by the body through different pathways. Vitamin B2 is water-soluble and primarily excreted through urine, while vitamin D is fat-soluble and stored in the body's fatty tissues and liver. They do not compete for absorption or interfere with how the other works.

What you should do

It is safe to take vitamin B2 and vitamin D together. Always follow the dosage instructions on the product packaging or those provided by your healthcare professional. Taking vitamin D with a meal containing some fat can help your body absorb it better.

Important precautions

Hypercalcaemia (high blood calcium)

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

Food and drink warnings

Alcohol

It is best to avoid or strictly limit alcohol when taking Vitamin B2. Alcohol can interfere with the way your body absorbs this vitamin from the digestive tract, making the supplement less effective.

High-fat meals

Vitamin D is fat-soluble. It is best absorbed when taken with a meal that contains some fat (such as eggs, avocado, nuts, or dairy). Taking it on an empty stomach may reduce how much your body absorbs.
