Protection against obesity - How promising is nicotinamide riboside, a substance found in milk?

I read about this in a German magazine and did some online research.

‘Nicotinamide riboside, a natural ingredient found in milk, can protect against obesity even as mice continue to enjoy diets that are high in fat. The researchers who report their findings in the June Cell Metabolism, a Cell Press publication, liken this milk ingredient to a new kind of vitamin. “This is present in what we’ve all been eating since day one,” says Johan Auwerx of École Polytechnique Fédérale de Lausanne.

Mice that take nicotinamide riboside in fairly high doses along with their high-fat meals burn more fat and are protected from obesity. They also become better runners thanks to muscles that have greater endurance. The benefits they observe in mice wouldn’t be easy to get from drinking milk alone, Auwerx says. It may be more likely that the compound would serve as a new kind of metabolism-boosting supplement. Tests done in people are now needed to help sort out those details.’

Any thoughts?

Would you volunteer in a study?
