PERQUE was founded in 1987 by Dr Russell Jaffe, a physician, clinical pathologist, immunologist and biochemist, and is based in Ashburn, Virginia, in the United States. The company has always sold its formulas through doctors and healthcare professionals rather than through mass-market retail, and every product carries a full-disclosure label with no hidden or inactive ingredients. PERQUE guarantees 100% potency and activity for the entire shelf life of each product, uses forms of nutrients selected for bioavailability, and formulates without citrus, MSG, wheat, gluten, corn, dairy, yeast, soy, sulphates, phosphates (other than coenzymes) or preservatives. That transparent, practitioner-first approach aligns closely with Welzo's commitment to clear, quality-led nutrition, and Welzo's healthcare professionals assessed the brand for alignment with our standards before adding it to our range. Sleep Guard reflects PERQUE's preference for nutrients in the forms the body actually uses. It pairs 500 mg of L-tryptophan, the whole essential amino acid rather than 5-HTP, with pyridoxal 5'-phosphate and riboflavin 5'-phosphate, the coenzyme forms of vitamins B6 and B2 that do not need enzymatic activation. A small amount of plant silica from horsetail is included, and the only other components are the vegetable capsule, croscarmellose and palm-derived alkyls, all declared by weight. The vegetarian capsule, non-GMO sourcing and the absence of gluten, dairy, soy, yeast and preservatives make the product straightforward to recommend across a wide range of dietary needs. This attention to detail reinforces our trust in their quality philosophy.
