What nutrients does Ozempic deplete?

Ozempic does not directly deplete nutrients the way some medications do. What it does is dramatically reduce food intake, and reduced food intake means reduced nutrient intake across the board. The depletion is indirect but clinically significant.

The mechanism

Semaglutide reduces appetite and slows gastric emptying. Clinical data shows caloric intake can drop by 16 to 39% during treatment. Research published in Obesity Reviews in 2026 confirmed there has been very little study of how GLP-1 medications affect overall diet quality, protein intake, or micronutrient intake, but the existing evidence raises clear concerns about nutritional adequacy.

The nutrients most affected

B vitamins. B1, B6, B9, and B12 are predominantly obtained through food. When food intake drops significantly, B vitamin status drops with it. B vitamins are essential for cellular energy production. Deficiency is a primary driver of the fatigue many Ozempic users experience.

Vitamin D. Found primarily in fatty fish, eggs, and fortified dairy, foods often consumed in smaller quantities during GLP-1 treatment. Vitamin D deficiency is already widespread; reduced food intake compounds the risk.

Zinc. Critical for immune function, wound healing, and hair follicle health. Reduced intake is associated with impaired immune function and contributes to hair loss in the context of rapid weight loss.

Iron. Iron deficiency is a known risk during any period of significant caloric restriction, particularly for women. Symptoms overlap with general GLP-1 fatigue: exhaustion, brain fog, and reduced physical capacity.

Magnesium. Involved in over 300 enzymatic reactions. Deficiency contributes to muscle cramps, poor sleep, and increased anxiety.

Potassium and sodium. Reduced food intake and GI side effects can deplete electrolytes rapidly. Electrolyte imbalance is responsible for many symptoms GLP-1 patients attribute to the medication itself.

Protein. Research consistently shows up to 40% of weight lost on these medications is lean muscle. Insufficient protein intake accelerates that loss.
