Opurity Bypass-Optimized chewable multivitamins are made by the same company that makes Unjury protein supplements, which are high-quality protein supplements suitable for gastric bypass patients. Therefore you might assume the Opurity multivitamins would be of equally high quality. How do they measure up?
The American Society for Metabolic and Bariatric Surgery recommends that gastric bypass patients take a multivitamin supplement that provides 200 percent of the recommended daily allowance of most nutrients. The ASMBS advises gastric bypass patients to take additional calcium citrate, B12 and iron beyond what they get from their multivitamins. In order to get 200 percent of the RDA of most nutrients, patients must take two servings of most brands of multivitamins. Opurity differs from the norm because just one chewable tablet provides 200 percent of many nutrients.
However, Opurity falls short in a few areas. Most notably, the Opurity multivitamins for gastric bypass patients contain no copper whatsoever. The Neuromuscular Disease Center at Washington University in St. Louis reports that gastric bypass patients are at increased risk for copper deficiency, though. Copper deficiency can have very serious effects, including a “pins and needles” feeling in the hands and feet (due to nerve damage), difficulty walking, muscle weakness, osteoporosis, anemia, fatigue, confusion and depression. That’s not something I personally would choose to risk.
Opurity Bypass-Optimized chewable multivitamins provide only 150 percent of the RDA of vitamin A rather than 200 percent, but 150 percent may be sufficient. It should be noted that half the vitamin A comes from beta carotene, which is not absorbed well at all in gastric bypass patients. Many bariatric multivitamins contain 50 percent vitamin A from beta carotene though, so Opurity is not unique in that regard.
They contain a combination of calcium citrate and calcium carbonate, even though gastric bypass patients do not absorb calcium carbonate well at all (one study found they only absorb about four percent of it), but that may not be significant because patients would need to take additional calcium anyway in order to get the 1500 to 2000 mg recommended by the ASMBS. No single multivitamin will contain that much calcium. Calcium carbonate does still seem like an odd choice for a vitamin meant for gastric bypass patients, though, since they cannot absorb it.
The bottom line is that Opurity Bypass-Optimzed chewable multivitamins may provide a decent option for gastric bypass patients but patients may need to take some additional supplements, including additional vitamin A and particularly copper. Having to take only one multivitamin a day would be convenient, but that convenience may be offset by needing to take a copper supplement along with it.
