History
Nature's Bounty was founded in 1971 by Arthur Rudolph as a mail-order supplement company. It grew rapidly through the 1980s and 1990s, renamed itself NBTY in 1995, and became one of the largest vertically integrated vitamin manufacturers in the country, eventually owning brands like Solgar, Puritan's Pride, and Osteo Bi-Flex.
The company changed hands repeatedly through private equity: the Carlyle Group bought it in 2010 for roughly $3.8 billion, and KKR took a majority stake in 2017, renaming the parent The Bountiful Company. In 2021 Nestlé acquired the company's core vitamin brands, Nature's Bounty, Solgar, Osteo Bi-Flex, and Puritan's Pride, plus its U.S. private-label business, for $5.75 billion, folding them into Nestlé Health Science.
The brand has been a recurring subject of testing scrutiny in the fish-oil category specifically. A 2012 Consumer Reports investigation found detectable PCBs in Nature's Bounty fish oil samples, among several brands tested, though none exceeded the thresholds Consumer Reports flagged as concerning at the time. NBTY (the corporate predecessor) was also named, along with other major supplement makers, in a 2010 California Proposition 65 suit over undisclosed PCB levels in fish oil products, which was resolved by consent judgment.
Why it is trusted
- +It is a large, long-running manufacturer with its own manufacturing footprint, which gives it more direct control over quality than brands that only broker contract manufacturing.
- +Now backed by Nestlé Health Science, a large, publicly accountable parent with regulatory and legal exposure to protect.
- +The brand does not broadly publish batch-level certificates of analysis or carry USP Verified status across its line, so consumers largely have to trust label claims rather than checkable documentation.
- +It has drawn more independent lab scrutiny and more class-action litigation over label and quality claims than most brands in this list, reflecting its scale as much as any unique failure.
Where we would be careful
- −Its fish oil line was flagged for detectable PCBs in a 2012 Consumer Reports test, among other major brands tested that year.
- −A 2021 class action (Baines v. Nature's Bounty) alleged deceptive labeling on its fish oil products; check current litigation status before assuming any claim has been resolved either way.
- −Verification is inconsistent product to product, check the specific bottle rather than assuming brand-wide certification.
