I would encourage you to watch the youtube videos on vitamin D by Dr John Campbell. I actually double dose on these (8000IU) because of the new studies that are coming out thick and fast. Hope this helps. **Q: Strength too high? 19-70 yr olds recommended only 600 iu daily? so why so strong???** A: You can take much higher dose each day without doing any harm i have been taking 4000 iu for three years. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Efficacious *by L***E on 17 August 2026* Good product, very competitive price for quantity which is 1 years supply.
