Do vitamins help prevent deficiencies while on weight-loss injections?
Part of Hormones & metabolism clinical trials.
This trial tests if a daily multivitamin and mineral tablet can prevent nutrient shortages in people taking GLP-1 medicines (like Wegovy or Saxenda) for weight loss. You would take either the vitamin tablet or a placebo (a tablet with no active ingredients) for a year, to see which group has better nutrient levels.
