According to a 2025 report from PharmaShots, the global nutraceuticals market is projected to reach nearly $1 trillion by 2032, highlighting the intense competition to be known as the top nutrition company. This article dives deep into the factors that define a leader in this complex industry, from market share and product quality to consumer trust and innovation. We will examine the top contenders and help you understand what makes a company truly stand out in the crowded health and wellness space.

In October 2025, the weight management landscape saw significant shifts with the announcement that Glanbia had sold its SlimFast brand rights to two separate entities. This change has left many consumers questioning the continued availability of the iconic product line that has been a staple in diets for decades. The short answer is yes, SlimFast is still available, but where and how you find it now depends on your location.

According to Fortune Business Insights, the global food supplement ingredients market was valued at over $16 billion in 2024, a testament to a booming industry now facing rising costs. Consumers are keenly aware of this trend and are asking: why is Optimum Nutrition so expensive now?

Since its founding in 1986, Optimum Nutrition has been a trusted leader in sports nutrition, helping athletes achieve their goals. The company was established with a singular focus on bringing consistent quality to the marketplace, a principle that still serves as the core of its mission statement today.

Isopure was indeed founded in the United States, but as of 2014, it is no longer American-owned, having been acquired by the Irish nutrition conglomerate Glanbia Plc.

According to a 2024 Euromonitor report, Herbalife was ranked as the number one active and lifestyle nutrition brand globally, though the answer to "What is No. 1 nutrition company?" largely depends on the specific market segment and metrics used. Different industry leaders specialize in various areas, from sports performance to clinical care, making a single definitive title impossible.

Isopure often stands out on shelves for its premium price, a factor that can deter many potential customers. This cost is largely influenced by the manufacturing process and the emphasis on using 100% whey protein isolate.

In 2008, the Irish multinational nutritional and food company Glanbia plc acquired the sports supplement company for $315 million, confirming that the multinational corporation currently owns the Optimum Nutrition brand.

According to Optimum Nutrition's own website, the company is one of the few sports nutrition brands that owns and operates its own manufacturing facilities. This means that the brand can maintain strict quality control by producing a significant portion of its products, including the popular Gold Standard 100% Whey, in-house.

In 2000, consumer goods giant Unilever purchased SlimFast for an astounding $2.4 billion at the peak of its popularity. The brand dominated the meal replacement market for years, so what happened to SlimFast, and why did its value eventually plummet?
