Natural Alternatives International
NAI was founded by Mark LeDoux in 1982 and went public in 1994. The firm manufactures private-label nutritional supplements for major brands. LeDoux and his family have used the proceeds from NAI's operations to build a family office vehicle that invests across healthcare and consumer health sectors. The family office strategy focuses on direct investments in companies aligned with NAI's core competency in nutritional science. Known holdings include stakes in supplement ingredient suppliers and contract manufacturers. The geographic focus is North America, with some exposure to Asia through supply chain relationships. The office makes both equity and debt investments. Mark LeDoux remains CEO of the public company, and his family office operates from Carlsbad, California. The team is lean, with fewer than a dozen professionals managing both public company responsibilities and family investments. No additional offices have been publicly identified. The structural differentiator for this family office is its tight link to a public operating company. Investment decisions are informed by decades of experience in regulatory and manufacturing dynamics in the supplement industry. This insider perspective shapes a mandate that other family offices focused on healthcare may lack.
