Fish-derived vs synthetic vitamin D for low vitamin D levels
Part of Hormones & metabolism clinical trials.
This study compares two types of vitamin D supplements – one made from fish waste and one synthetic – to see if they work equally well in healthy adults who have low but not severely low vitamin D levels. If you qualify, you would take one of the two supplements and your vitamin D levels would be monitored over time.
