Nerval is a tonic that is supposed to relieve stress and emotional fatigue. The picture associated with the product on the Healthy People website is a woman sleeping. We are unsure about that picture because the product contains a common stimulant used in fat burners. Ideally, this supplement should not be taken within six hours of bedtime, but not all dieters will feel increased energy because guarana is not as strong as straight caffeine.

The Healthy People website makes a long list of health claims associated with Nerval. Most of these claims are not supported with medical research or clinical study. Healthy People is known for listing benefits that are not supported, so this is not anything new. However, there are positive benefits associated with some of the ingredients in the tonic.

Product Features

Valerian is the first ingredient in the tonic. There is no mention of how much of each ingredient is included in the formula, but valerian is commonly taken as a natural sleep aid. Over time, valerian works to make it easier to fall asleep, but the ingredient is also used in supplements to reduce stress with some success. If the valerian makes you tired or if you are already taking valerian root, it may be best to skip Nerval.

Guarana is the interesting ingredient in Nerval. According to the product description from Healthy People, Nerval will not make the user sleepy, but the product contains valerian. We’re thinking they added guarana, a natural source of caffeine, to Nerval to counteract the sleepiness associated with taking Nerval. But, again we are faced with guessing because we have no idea how much guarana is added so we have no idea if there is enough to affect sleep or even increase energy at all.

Black walnut is a tree nut. Dieters who are allergic to tree nuts should NOT use this supplement.

  • Contains a strong vitamin profile.
  • May improve mood and relieve the feelings associated with stress.


  • May cause drowsiness.
  • May not be safe for people with nut allergies.
  • Should not be taken if the dieter is already taking valerian root.
  • May increase sleepiness if taken with melatonin.


Guarana is a stimulant and valerian root is a natural sleep aid. Taking the two together seems a little odd, but if one counteracts the effect of the other while allowing the user to take advantage of a secondary effect, the combination is sound. The supplement description is a little bit light from Healthy People. We’d like to see some clinical support and a few testimonials.
