New professional-grade supplements, including next-generation probiotics, strengthens the online retailer’s position as a leading destination for non-prescription health products recommended by physicians and healthcare professionals
IRVINE, Calif., APRIL 16, 2025 -- iHerb, one of the world's leading online retailers for vitamins, minerals, supplements and other health and wellness products, is significantly leaning into the Professional Brands category with the recent additions of Metagenics®, Pure Encapsulations® and Designs for Health®. These industry-leading brands join Thorne® and other professional grade brands available at iHerb, which serves a global consumer base located in 180 countries.
Professional-grade vitamins, minerals, and supplements (often referred to as “practitioner-grade”) are high-quality nutritional products that are typically formulated with higher dosages of active ingredients, based on clinical research and scientifically-backed ingredients. They are generally recommended by physicians, naturopaths, and other healthcare practitioners to help support specific health concerns or to address micronutrient deficiencies in a precise and reliable manner. *
Why Use Professional Brands?
Professional-grade supplements are known for their potency, purity and quality standards as they are manufactured under strict quality control measures. They are often subjected to third-party testing for purity, potency, and the absence of contaminants such as heavy metals, pesticides, and fillers. This ensures that the supplements contain exactly what the label claims, with fewer risks of impurities. †
Since these supplements are often recommended by healthcare practitioners, they are usually part of broader recommendations that includes dietary and lifestyle changes. This professional oversight ensures that the supplements are appropriate for the patient’s individual health needs, reducing the risk of unnecessary or incorrect use. †
“As one of the leading authorities on natural medicine, I’ve seen the benefit of professional-grade supplements among patients given the consistent quality, potency and safety of these products,” said Dr. Michael T. Murray, Chief Scientific Advisor for iHerb. “Professional brands often come with clinical studies supporting their use, which is strong evidence on the effectiveness of their natural products.”
“We’re seeing consumers increasingly turn to high-quality, professional-grade supplements at the recommendation of their healthcare practitioner,” added Lindsey Wiefels, SVP of Merchandising at iHerb. “We’re proud to meet the demands of the market with these highly respected brands.”
Next-Generation Probiotics
With the growing focus on digestive health among consumers, iHerb is also introducing cutting-edge probiotics from Pendulum and Codeage that contain Akkermansia muciniphila, a natural gut microbe that supports the gut lining and helps maintain a healthy balance of insulin and glucose levels. Unlike other species of beneficial bacteria such as lactobacillus and bifidobacteria, Akkermansia plays an important role in supporting appetite, body weight, and metabolic health.†
iHerb is committed to monitoring health trends and emerging scientific research to provide the latest innovations in dietary supplements as part of its assortment. The addition of these new brands aligns with the company’s mission to deliver the best selection of health and wellness products to customers worldwide.
