I don't recommend these vitamin D3 capsules, but not because of their quality. That may be OK for someone who doesn't mind GM products. Due to my own carelessness I failed to notice they are mixed with soya oil. As we know soya oil, especially from the US as these are, is Genetically Modified. They don't have to label them as GM by law. So I will not be swallowing these capsules but have flushed them down the loo. My own fault.
