Procter & Gamble will acquire Summerville-based supplements maker Thorne for $3.8 billion. This all-cash deal signals a strategic expansion into the personal wellness and beauty-products industry.

P&G executives identified the supplements category as a high-growth priority following shifts in consumer health behavior. The company reportedly won the acquisition over several other multinational bidders in a fragmented market.

The 189-year-old company aims to reach new demographics beyond its traditional household staples portfolio. The transaction is expected to close by the end of the year. This deal represents one of the most significant recent M&A activities in the consumer staples sector.
