Tablets are to small Review by
  • star

I can swallow these tablets whole without water easily.

To suggest they're too big is silly, crush them up if you can't swallow them!!

Solved size problem Review by
  • star

It was suggested to me to swallow these tablets with Yoghurt. I place tablet in 1 desert spoon of yoghurt, and slides down fine.

Too big Review by
  • star

These tablets are massive and very hard to swallow.

Tablets too large. Review by
  • star

These tablets are humongous and just looking at them sends my throat into a spam so unfortunately I cannot take them. Even cutting them in half doesn't do the trick.

Not for anyone who struggles with big tablets Review by
  • star

This is a great strength but I found great difficulty swallowing the huge tablets so have gone back to the capsule form
