What is known about the ingredients
- Passionflower: can cause drowsiness, dizziness or confusion and may add to the effect of sedatives and sleep medicines
- Corydalis: contains alkaloids with sedative effects; drowsiness, dizziness and nausea have been reported, and there are reports of liver problems with corydalis products
- California poppy: traditionally used for its calming effect; it may increase drowsiness with sedatives or alcohol
- Marshmallow root: generally well tolerated; its mucilage can slow the absorption of medicines taken at the same time, and it may lower blood sugar
- Prickly pear cactus: generally well tolerated in food amounts; it may lower blood sugar and can cause mild stomach upset
Drowsiness, alcohol and driving
Because three ingredients are calming botanicals, see how Nerve Fresh affects you before driving or operating machinery, and avoid combining it with alcohol. The maker suggests a capsule before bed; that does not remove the need for caution in the morning.
Who should talk to a doctor first
- People taking sedatives, sleep aids, anxiety medication, opioid or other pain medicines, or antidepressants
- People with diabetes or on blood-sugar medication
- Anyone with liver disease or a surgery coming up
- Pregnant or nursing women
- Children and teenagers – it is made for adults
- Anyone with numbness, tingling or nerve pain that has not been diagnosed
Is Nerve Fresh FDA approved?
No supplement is FDA approved; the FDA does not review supplements before they are sold. The maker says Nerve Fresh is made in an FDA-registered, GMP-certified facility in the USA – that concerns the facility, not approval of the product.
How to use it safely
Stick to the serving on the label (2 capsules a day), take other medicines a couple of hours apart from it unless your doctor says otherwise, and do not stack it with other calming supplements. Stop and get medical advice if you notice unusual tiredness, yellowing of the skin or eyes, dark urine, stomach pain or an allergic reaction.
