5Strands is a US-based direct-to-consumer health testing brand operating at 5strands.com. The company specializes in at-home hair-sample test kits designed to identify potential food intolerances, environmental sensitivities, and nutritional or vitamin/mineral imbalances. According to the website, more than 450,000 customers have used 5Strands testing products, making it one of the more established names in the at-home intolerance testing space.
The product catalog is divided into two main audiences: people and pets. For people, 5Strands offers kits covering food intolerances, environmental sensitivities, and vitamin/mineral imbalances, as well as a BlueGreen Algae water test and personal consultations. For pets — primarily dogs and cats — the same categories are available, giving pet owners a non-invasive way to investigate unexplained symptoms such as itching, digestive upset, or lethargy. A quiz tool is available on the site to help shoppers identify the most appropriate kit for their situation.
Testing with 5Strands involves collecting a small hair sample at home and mailing it to the company's lab. Results are then delivered digitally. The company provides educational resources including guides on how to read intolerance results and imbalance results, a blog, success stories, and an FAQ section, supporting customers through the process from purchase to interpretation.
From a purchasing standpoint, free shipping is offered on US orders of $50 or more. An affiliate program and a wholesale collection are also available for partners and bulk buyers. The store can be reached by phone at +1-833-600-8378. Social media presence includes Facebook, Instagram, and YouTube channels where the brand shares educational content and customer stories.
It is important to note that 5Strands tests are not medical diagnostic tools and are not intended to replace advice from a licensed healthcare professional. The methodology is based on hair sample bioresonance-style analysis, which differs from clinically validated allergy blood tests or skin-prick tests performed by allergists. Consumers should consider these tests as a wellness and lifestyle guidance tool rather than a definitive medical diagnosis.
