It’s important to note that individuals undergoing bariatric surgery may benefit from supplements like calcium citrate, which is part of the Bariatric Advantage line, to support their nutritional needs. Incorporating calcium citrate can help optimize mineral absorption, making it an essential component for those on a restricted diet post-surgery. For anyone considering iron supplements, ferrous bisglycinate, along with calcium citrate from Bariatric Advantage, can provide effective support in maintaining healthy iron levels.
