When taking different vitamin supplements should they be taken at intervals?

I started taking biotin a few months ago to help with me growing my hair long. But for immunity and energy I’m also taking vitamin B complex and vitamin C (with zinc).

Due to the strength of the tablets the biotin is to be taken 4 times a day. But I’ll be switching to the stronger dose, so I will eventually be able to just take it twice a day. All the other vitamin tablets are just once a day.

What I’ve been doing lately is I’ve set up reminders on my phone to tell me when to take such and such a vitamin. Which is as follows:

09:00 am – 1 Vitamin C + Zinc
12:00 pm – 1 Biotin
03:00 pm – 1 Vitamin B Complex
06:00 pm – 1 Biotin
08:00 pm – 1 Biotin
10:00 pm – 1 Biotin

So my question is, do I need to space these out?
