Weight loss surgery changes how your body digests and absorbs nutrients. Reduced stomach capacity, altered digestive anatomy, and lower stomach acid production mean standard multivitamins often don't provide adequate levels — or the right forms — of essential nutrients. Bariatric-specific vitamins are formulated to meet these unique needs and help address the deficiencies most common after surgery, including iron, vitamin B12, calcium, and vitamin D.

Most bariatric programs recommend starting vitamin and mineral supplementation within the first week after surgery, typically beginning with chewable or liquid formats. Always follow the specific timing and dosing guidance provided by your surgeon and bariatric care team.

Bariatric supplementation is a lifelong commitment. Because weight loss surgery permanently changes nutrient absorption, daily supplementation is recommended for the rest of your life to help support long term health and prevent deficiencies.

We organize our catalog by surgery type to make this easier: gastric sleeve, gastric bypass, lap band, and duodenal switch. You can browse the collection that matches your procedure, or reach out to our team for personalized guidance. Many patients benefit from our advanced multivitamin, calcium citrate, vitamin B12, and vitamin D3 as core staples, with iron and biotin added as needed.

Yes. Most of our products come in chewable, soft-chew, or gummy format — all of which are significantly easier to tolerate after bariatric surgery than large capsules. These formats are also less likely to cause digestive discomfort in the early post-op months.

Absolutely. While our products are specifically formulated for post-bariatric needs, they're high-quality supplements appropriate for anyone looking for gentle, well-dosed, easy-to-take vitamins. If you're unsure whether a specific product fits your needs, consult your healthcare provider.

Our formulas are developed in collaboration with bariatric nutrition experts and designed to reflect the nutrient recommendations published by the American Society for Metabolic and Bariatric Surgery. This includes appropriate dosing of iron, calcium, vitamin B12, vitamin D, and the full complement of essential micronutrients.

Iron needs vary based on surgery type and individual factors. Our 18mg option is typically suited for gastric sleeve and lap band patients with standard iron needs. The 45mg formula is geared toward gastric bypass patients, and the 60mg formula is designed for duodenal switch patients or those with higher iron requirements. Always consult your care team for personalized recommendations.

In most cases, yes — though calcium and iron should be taken at least two hours apart for optimal absorption. This is a general guideline for all bariatric patients, not unique to our products. Follow your care team's personalized regimen.

Our high-protein shakes are designed as meal replacements or supplements for bariatric patients who need dense, low-sugar, low-carb nutrition. Our snack bars are designed to support daily protein intake between meals. Use according to your bariatric care plan.
