Does yoga help increase supply?

While there is no direct link or conclusive studies done, yoga movements can actually help increase milk supply if done correctly. The milk production increase may be a result of the arm movements that increase serum nitric oxide, resulting in increased blood circulation. As yoga helps with stress, it could very well be the reason why it helps increase breast milk. Stress is a know milk supply killer so I suppose being in the zone, at ease during yoga helps :)
