Doctor's Best Launches Hair & Skin Complex

New Formula Features Nutrition21's Lustriva®, Clinically Shown to Increase the Growth of Fuller, Thicker Looking Hair*

TUSTIN, Calif., Sept. 4, 2025 /PRNewswire/ -- Leading into Healthy Aging Month this September, Doctor's Best Inc. has joined forces with Nutrition21, an Everwell Health company, to introduce Doctor's Best High Absorption Hair & Skin Complex with Lustriva^®. This innovative hair growth formula is designed to support individuals experiencing hair loss who are seeking effective, clinically-backed hair growth results.*

Doctor's Best High Absorption Hair & Skin Complex utilizes Lustriva, a patented, one-of-a-kind ingredient developed through extensive research by Nutrition21. Lustriva provides a unique combination of bioavailable nutrients that promote healthy hair and skin, including Bonded Arginine Silicate and Magnesium Biotinate. This novel ingredient offers specialized forms of both silicon and biotin, which can support hair follicles during their active growth phase and regulate key activities important to the skin's integrity and function. Clinical studies have shown that Lustriva can support the growth of existing hair, helping to achieve a fuller, thicker appearance in as little as three weeks.*¹ Additionally, it has been shown to improve skin texture and reduce facial wrinkle depth after twelve weeks of use.*¹

Hair loss affects tens of millions of Americans, impacting self-esteem, self-image, and overall quality of life. Approximately 50 million men and 30 million women in the United States experience male and female pattern hair loss.*²

"Hair loss is a deeply personal issue that affects both men and women, often impacting them for decades," said Gale Bensussen, CEO of Doctor's Best. "Our partnership with Nutrition21 reflects our mutual commitment to quality and innovation, and we believe this product will help support those seeking rejuvenation for their hair and skin."

In addition to Lustriva^®, the Doctor's Best Hair & Skin Complex includes Vi-Spo^®, a branded ingredient derived from saw palmetto, which has shown superior clinical efficacy compared to conventional saw palmetto oil. Saw palmetto is known for its ability to help reduce hair loss and promote hair growth. The collaboration between Nutrition21 and Doctor's Best leverages both companies' expertise in nutritional health and innovative ingredient development. This new hair growth supplement aims to meet the increasing demand for effective solutions to support hair health and beauty from within.

"The demand for beauty from within supplements continues to grow as today's consumers seek out solutions that promote healthy hair and skin to address the signs of aging," said Jordan Miller, VP of Marketing for Nutrition21. "We are proud to offer Lustriva^®, a clinically validated beauty ingredient that gold-standard brands like Doctor's Best can trust, ensuring products - such as Doctor's Best High Absorption Hair & Skin Complex with Lustriva - deliver real results consumers can see and experience."
