When it comes to the supplements you rely on every day — especially after weight loss surgery — quality isn't a marketing claim. It's a responsibility. At BariSlim, we hold our products to rigorous standards because our customers' long-term health depends on it. Here's how we make sure every bottle meets the bar.
Every BariSlim product is formulated in the United States, developed in collaboration with bariatric nutrition experts and engineered specifically for post-surgical needs. While most of our products are manufactured domestically, select items are produced at trusted overseas facilities chosen for their specialized capabilities.
Every manufacturing partner we work with — domestic and international — is GMP (Good Manufacturing Practices) certified and ISO certified, meaning they follow internationally recognized standards for quality control, sanitation, ingredient sourcing, batch documentation, and consistent formulation. It's how we make sure you get the same BariSlim standard in every bottle.
For select products in our lineup, we go a step further and conduct independent third-party laboratory testing to help verify identity, potency, and purity. We continue to evaluate our catalog and expand independent testing where it adds the most value for our customers.
In every case, we hold our manufacturing partners to consistent quality standards so that what's on the label reflects what's in the bottle.
Our formulas are designed to meet the nutrient recommendations set forth by the American Society for Metabolic and Bariatric Surgery (ASMBS) — the leading professional body for bariatric care in the United States. This means our multivitamins, calcium, iron, B12, and other supplements are formulated to address the specific nutrient needs of patients after gastric sleeve, bypass, lap band, and duodenal switch surgery.
Not all vitamin forms are absorbed equally, especially after bariatric surgery. We use nutrient forms specifically chosen for their bioavailability in post-surgical patients — including calcium citrate (which doesn't require stomach acid for absorption), methylated B12, and chelated iron. The right form makes the difference between a supplement that supports your health and one that passes through unused.

We believe bariatric patients deserve clarity, not marketing fluff. Our labels list exactly what's in the product, in the amounts stated. Our website provides full ingredient transparency. And we're careful to make only the structure/function claims supported by science — never inflated promises.
Quality isn't a one-time check. We continually review our formulations, source ingredients from reputable suppliers, and update our products as bariatric nutrition science evolves. If an ingredient can be improved, if a form can be made more bioavailable, or if a formula can be made more tolerable — we'll make the change.
Our commitment is simple: the bariatric community has placed their trust in BariSlim, and we work every day to earn that trust all over again.
