The short read
The UPC number for this Nature's Trove L-Theanine product matches what's listed, meaning it's the correct item. However, without the product's net weight, unit
Why this result?
We ran this product through public-record checks — label math, barcode registries, FDA recall lists, published lab tests. This banner sums up what those checks could and couldn’t confirm. Green means nothing public contradicted the label — not proof it works or is safe. Gray means the data to check simply isn’t public: a gap, not a verdict. We show the evidence; the conclusion is yours.
Confirmed evidence
What checked out01
These checks found support in the public record. They confirm specific facts, not the product as a whole.

Documented concerns
What needs caution00
These are documented contradictions or claims that need more evidence. They are separate from missing data.
No contradictions or product-specific cautions were found at this check depth.
Unresolved public record
What is still missing04
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The listing doesn't publish enough to check the math
What this means: the listing doesn't publish net weight, unit count, per-serving dose, servings per container, so the dose claim can't be checked against physics from public data. That's neither a pass nor a strike — but it does mean you're taking the label on faith. Checkable products publish these numbers.
No label filed with NIH's public catalog
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
180-day review-count history is on file
Exact-listing history records written-review counts from 3,642 on 2026-01-29 to 3,817 on 2026-07-13 (net +175). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
This item belongs to a catalog variation family
The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.
What to ask and check
What would settle the open questions
Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.
Ask the brand or seller
1
Can you send a clear photo of the full Supplement Facts panel?
It’s the one part of the label required to state what’s inside and how much. A seller who won’t show it before purchase is asking for trust the label would have earned.
2
Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?
Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.
3
Where are the ingredients sourced, and where is the product manufactured?
“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.
Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.
Check for yourself — no one’s permission needed
1
Scan the barcode on the package and confirm it reads 850056289016.
A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.
2
Check the lot number and expiry on the bottle against any COA you’re given.
A certificate that doesn’t name your lot doesn’t describe what you’re holding.
These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.
