Nerve Supplement or Medicine? Why the Difference Matters at the Pharmacy
A nerve supplement is not a medicine. Medicines are reviewed by FDA for a stated use before sale, while supplements are not, and they may not claim to treat disease. Flow Nerves is a supplement. Keep taking prescribed medicine as directed and tell your pharmacist about both.

Legal line01
What makes a product a supplement and not a medicine?
The law, the label and the claims, in that order.
Under the 1994 supplement law, a dietary supplement is a product taken by mouth that holds ingredients such as vitamins, minerals, herbs or amino acids, and is labeled as a supplement 1. FDA does not approve these products before they are sold, and the maker must make sure they are safe 2. A medicine has to show it works for a stated use before it is sold.
That is why a supplement label talks about "support" and carries a star and a disclaimer, while a medicine label names a use 3.

At the counter03
Why does it matter at the pharmacy counter?
Because the pharmacist can only check what they are told about.
Many people mention their prescriptions and skip the bottle in the cupboard. Supplements can still interact. Alpha lipoic acid may lower blood sugar, so it matters with insulin or diabetes pills. Turmeric and L-carnitine are on the ask-first list for blood thinners, and CoQ10 may weaken warfarin. Magnesium can affect some antibiotics and bone medicines. NCCIH urges people to tell every provider about the supplements they use 5.
Keep taking prescribed medicine as directed. If a medicine seems to stop working or you have side effects, call your prescriber. For emergencies call 911.

FAQ06
Flow Nerves questions people ask
Can a nerve supplement take the place of a prescription?
No. Keep taking prescribed medicine as directed, and ask a clinician before any change.
Why does a supplement label carry a star and a disclaimer?
The star points to wording that says FDA has not evaluated the statement and that the product is not meant to treat a disease.
Does a pharmacist need to know about a capsule I buy online?
Yes. Online and shelf capsules can both interact, and the pharmacist cannot see what you have not mentioned.
Is a prescription nerve drug stronger than a supplement?
They are different products with different rules and uses. Strength is not the right comparison, so ask your prescriber what fits.
