This product is a very good buy economically and I really notice some specific health benefits. I'm titrating my vitamin D levels to reach 150nmol/L, in my case that means taking 20,000 - 25.000 IU a day. Don't do this unless you get your levels testes. Anyway, with this optimal level using this product I have virtually no SAD or other depression symptoms which used to affect me in the winter, my joints don't ache any more and a small benign tumour on my left thigh which was about 4 mm in diameter and about 3 mm high has shrunk to about half the size over the past several weeks. This tumour has been present and gradually grown over the last 5 or 6 years. I did not expect the high vitamin D dose to shrink it, this but it makes me very happy as I was diagnosed with and treated for stage 3 breast cancer 7 years ago. I started learning about vitamin D after my diagnosis and have been taking it since, just not in the higher dose I use now. Seeing that little growth shrink is giving me hope that is there are any other little tumours inside my body now, cancerous or benign, that they will also stay under control. Another small growth I've had on my left cheek for many years is also disappearing. Great product for a great price, recommended.
