In the crowded field of natural supplements, it's easy to forget not all products begin with clinical data—or quality ingredients, rigorously tested for potency and purity. For more than 40 years, Jarrow Formulas' unyielding commitment to science has driven its new product development and informed the company's mission: to provide clean, efficacious supplements validated by the most up-to-date research, and ensure customers are healthy, optimistic and empowered, right down to their cells.

All supplements are developed through years of intensive research and innovation, using superior science as the guiding principle. That's how Jarrow Formulas has grown from a handful of offerings to hundreds of nutritional supplements, many of which were firsts for the industry—earning the company a reputation as the leader in research-backed probiotics. 

It Starts With Science

At Jarrow Formulas, new product development always starts with first-rate science. A painstaking adherence to cutting-edge research, combined with quality ingredients and extensive testing, forms the backbone of its innovation process. The company's skilled scientists and health professionals stay actively involved in clinical studies, continually working with researchers from universities and institutes around the world. A dedicated staff of experts synthesizes current data with knowledge gathered from renowned researchers specializing in the physiological impact of ingredients and products. Leveraging these up-to-date findings, Jarrow Formulas supplements are carefully crafted to guarantee full biological value and potency and maintaining the company's exacting standards.

Avena outlines that one of the things that is notable about Jarrow Formulas is that its formulas are specially formulated with counter vitamins and minerals to assure the most effective absorption. For instance, she explains, Jarrow Formulas’ Zinc Balance contains zinc and copper, so that you don’t become deficient in copper, which can sometimes happen when taking a zinc supplement. “Jarrow products are clinically studied and they put a lot of effort into the scientific research. Their motto has been, ‘Superior science, smarter formulas’ and I really believe that is what embodies the brand because their products are based and rooted in the science,” she adds.

Once the latest science has been scrutinized, all Jarrow Formulas supplements are manufactured with the highest-caliber ingredients, ensuring the safest, most effective products on the market. Ingredients are sourced only by suppliers who follow stringent Current Good Manufacturing Practices (cGMP) to verify safety and potency. Using state-of-the-art laboratories and techniques, a team of trained specialists test all raw materials, including both active ingredients and excipients, evaluating their purity, strength and composition.  In addition to validating raw materials, Jarrow Formulas analyzes every product at several points in the manufacturing process to uphold the company's "Total Quality" approach—guaranteeing customers the utmost confidence and trust, and a commitment to quality in every supplement. All products are tested by third-party labs that are ISO and USDA accredited, confirming purity and potency. Jarrow Formulas is also cGMP Certified by NSF International, the foremost organization in providing strict criteria for health and safety standards.

This scrupulous adherence to science, combined with verified ingredients and rigorous testing, adds up to smarter supplements. And nowhere is cutting-edge data more vital than in the field of probiotics.

“Probiotics are important to supporting gut health and can help the body regulate and adapt to immune responses,” says Avena. Even though many people have been told to look for CFUs, Avena explains, “CFUs don’t dictate if the product will work better. It’s the strains that matter, because you want to make sure you are getting a diverse gut microbiome filled with strong bacteria that can withstand bad ones without you even knowing they are there. The best probiotics are going to have clinically studied bacteria that are going to thrive in the gut and make beneficial changes to digestion and also support the immune system.”

When choosing a probiotic or a dietary supplement, Avena adds, “You want to make sure you are asking about the research. You want to know what studies have been done and how can you see the results. You should be able to see tangible and proven clinical studies that have been done.” 

Strains Matter

Ongoing research corroborates the intimate relationship between gut fitness, immune function and overall health. The intestinal microbiome is inextricably linked with immunity, and studies show 70 to 80 percent of immune cells are found in the gut. Probiotics play a critical role in regulating the gut microbiome, supporting intestinal wellness and strengthening the immune system. Dozens of studies verify their wide-ranging impacts on human health, and research confirms probiotics are an extremely effective way to enhance immunity and improve quality of life.*

B. coagulans and B. subtilis are resilient, spore–forming bacteria with excellent resistance to harsh gastric acids, able to remain viable during transit through the stomach and colonize the small intestine. This unique combination of live cultures encourages commensal  bacteria in the intestines, becoming incorporated into the microbiome and priming the gut for digestion.* Both B. coagulans and B. subtilis have well-established safety profiles and proven benefits, shown to support a balanced microbiome, enhance digestion and promote immunity.

Jarrow Formulas latest innovation: a line of probiotic gummies, informed by science and featuring a unique blend of both B. coagulans and B. subtilis for optimal gut health and immune support.*

Formulated with viable strains of clinically documented bacteria, skillfully designed probiotic gummies are just as effective as capsules.* And while many gummy supplements are filled with sugar alcohols, fillers, preservatives and other additives, Jarrow Formulas Probiotic Gummies are non-GMO, gelatin-free, gluten–free and vegetarian, and contain no artificial flavors, sweeteners, colors or preservatives.
