Vitamin D3 and Bisoprolol.

[Mjltazz]

Been given by gp vitamin D3 as she thinks my pins and needles and cramps are down to a deficiency in D vit deficiency. Anyway I’ve looked but can’t see an answer. When is the best time to take the vitamin? I take 2.5mg of bisoprolol in morning when I awake. Around 9-10am. As vitamin affects melatonin night time is not an option. I bearly sleep as it is. Lol. However I read somewhere it can weaken Bisprolol
