A 2024 Supplement Recall Example: Passing Samples and Unit Homogeneity Are Different Questions

Use a dated manufacturer notice to distinguish sampled results from a statement about uniformity across individual softgels.

A historical recall can reveal a documentation question that a generic tested badge leaves unanswered. This guide examines NOW Health Group’s notice dated January 10, 2024, as a specific past example. It is not a current warning about a seller’s stock, a live recall-status check or a conclusion about a bottle that a reader owns.

Identify the historical notice and its scope

The manufacturer’s January 2024 notice names phosphatidyl-serine softgels sold under NOW and Protocol for Life Balance, with two product codes and four listed lots. It attributes the recall to inconsistent homogeneity among individual softgels. The notice also says pre-shipment samples met specification. Retain the date, exact brand and listed identifiers when saving this case. Do not broaden the announcement into a statement about every phosphatidyl-serine product or silently attach its identifiers to a current listing.

Separate two different evidence questions

The historical notice illustrates why a statement about passing samples is not identical to a statement that every individual unit was shown to have uniform contents. US dietary-supplement manufacturing requirements in 21 CFR 111.75 separately address testing or examination, specifications and documentation, including sampling provisions. That regulatory source supplies context for the distinction; this article does not audit the company’s compliance or decide what a particular historical test should have detected. The document types answer narrower questions than a universal tested claim.

Worked scenario: give the past example its own record

Suppose an illustrative research sheet has one field saying this brand tests products. A researcher finds the dated recall and tries to replace that field with all products failed. Neither summary preserves the record. Create a historical-event row identifying the notice, its stated unit-homogeneity issue and its listed scope. Keep any sampled-results statement attributed to the manufacturer. A separate current purchase enquiry can then ask for the exact offered product documentation without presenting an old event as a newly issued alert.

Avoid using absence from this notice as clearance

A lot that is not named in a particular historical announcement has not thereby been certified by this article. Nor does a manufacturer’s description of its sampled results establish an individual bottle’s contents. For an actual recall question, consult the relevant current official and manufacturer information using the exact product details; do not use this worked historical case as a live lookup. The value of the example is its distinction between the scope of a sample statement and the scope of a unit-uniformity question. Keep the notice text intact for review, avoid turning it into a general brand ranking, and leave unsupported conclusions out of the purchase record. This approach preserves both the limited historical facts and the unresolved questions a buyer may need answered.
