FDA recall appears in this brand's history
An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
This recall is not about the product on this page. Premier Research Labs LLC recalled a different product on June 15, 2022. FDA has since closed that case. The recalled item was “AloePro Dietary Supplement Made With Organic ALOE VERA LIQUID 16 FL Oz.…”
Label #26067 “D3 Serum” (Premier Research Labs), entered 2013-10-25, with the full Supplement Facts on file. NIH marks this label as off-market (superseded or discontinued version). Company on file: Manufacturer — Premier Research Labs, Round Rock, TX.
Barcode checksum is valid; no independent product record was found.
These are evidence gaps, not strikes against the product.
