QUESTION
is nula fda approved?
no, and neither is any other dietary supplement. the fda does not approve supplements before they are sold — it regulates them as food rather than as medicine. any supplement brand telling you it is fda approved is either confused or misleading you. here is what the fda does actually require.
what the fda actually does with supplements
dietary supplements in the united states are regulated as a category of food, not as medicine. that means there is no pre-market approval step: a company does not submit a supplement for review and receive a yes before selling it.
so the phrase you sometimes see on packaging is meaningless at best. no supplement on any shelf is fda approved, because there is no approval to have.
what is still required
plenty. manufacturers must follow good manufacturing practice rules, label ingredients accurately, and avoid claiming a product acts on a disease — that last one is the line that turns a supplement into an unapproved drug in regulators' eyes.
any structure or function claim has to carry the standard disclaimer, which is why you see it in our footer on every page: these statements have not been evaluated by the food and drug administration. this product is not intended to diagnose, treat, cure, or prevent any disease.
what to look for instead of an approval stamp
a disclosed dose for every active, in milligrams, not hidden inside a proprietary blend total. nula lists l-theanine 100mg and gaba 50mg per serving.
third-party testing or certification, where a brand has it. olly's goodbye stress carries nsf certification, for example, which nula does not currently claim — that is a genuine point in their favour and we would rather say so than hope you do not notice.
claims that stay on the right side of the line. a brand promising a supplement acts on a diagnosed condition is telling you something about its regard for the rules.
common follow-ups
nula follows the manufacturing requirements that apply to dietary supplements. it does not currently carry a third-party certification mark, and we do not claim one.
not before sale. labelling accuracy is a legal requirement and the fda can act after the fact, but nobody verifies a supplement label in advance the way a drug is reviewed.
because it is required whenever a product makes a structure or function claim. it is on every page of this site, in the footer.
