简要总结

In animals, treatment with vitamin B3 improved insulin sensitivity and substrate metabolism. It is currently not know if vitamin B3 has the same positive effects in humans. In the current study the effect of a 3 month treatment with vitamin B3 on insulin sensitivity and substrate metabolism in obese men will be investigated.
