"I have been taking Valerian Root for about 4-5 years since my holistic Doctor suggested it. It has helped me relax and sleep more deeply without frequently waking up from muscle aches and pains. that and a change of eating habits and other supplements has made a huge difference! I find Nature's Answer as effective as any other brand I have tried. I also find that plain Valerian Root without additives seems to work as well as those with added herbs."
