Why this happens
Vitamin B complex (which includes B1, B2, B3, B5, B6, B7, B9, and B12) and Vitamin D use different pathways for absorption and metabolism. Vitamin B complex consists of water-soluble vitamins, while Vitamin D is fat-soluble. They do not compete for the same receptors or interfere with each other's effectiveness.
What you should do
It is safe to take Vitamin B complex and Vitamin D at the same time. To help your body absorb the Vitamin D better, it is best to take it with a meal that contains some fat (such as yoghurt, eggs, or avocado). Always follow the dosage instructions on the packaging or those provided by your healthcare professional.
