Ownership
Wholly owned by Pharmavite, itself wholly owned by Japanese pharmaceutical company Otsuka. Long-held; not a recent flip.
Why Approved
The only brand found that both owns its manufacturing and submits the bulk of its line to an outside body testing identity, potency and contaminants. USP's own directory lists 99 Nature Made products - 62% of the entire USP Verified program.
Reversibility
What would change our verdict
Nature Made's USP Verified product count falls materially below 99. Production shifts to contract manufacturers or the named US plants close.
