High quality supplement

I needed 4000iu of daily vitamin d and fortunately I found this supplement, much easier than getting out and swallowing 4 individual caps. Love sports research products for their high quality ingredients and minimal excipients.

Good value for money

I don't always notice a huge difference when taking supplements, but I read the reviews about the effect and quality of this vitamin D supplement. I like the value for money and use it alongside Magnesium. There's no taste which I like, they're small in size too so easy to take and no difficulty swallowing.
