Bold warning: some GLP-1 weight-loss users may be undermining their nutrition and risking serious health consequences like scurvy. While drugs such as Ozempic are effective at suppressing appetite, researchers warn that extremely low intake of nutrient-rich foods can lead to vitamin deficiencies that affect bone, brain, gut, skin, and muscle health. Scurvy, a condition driven by a severe lack of vitamin C, can cause anemia, bleeding gums, easy bruising, and slow wound healing, according to medical sources.
Public figures have spoken up about the issue. Musician Robbie Williams described developing scurvy after taking an Ozempic-like medication, noting he stopped eating and wasn’t getting essential nutrients. His account was shared with The Mirror.
A recent review from the University of Newcastle in Australia analyzed 41 controlled GLP-1 trials involving around 50,000 participants over 17 years. The study found that nutrition was only evaluated in two trials, and only one of those reported the nutritional data publicly, according to reporting in the Australian Financial Review.
Nutrition experts emphasize that nutrition data is a critical missing piece in understanding the full impact of GLP-1 therapies. Clare Collins, a professor of nutrition and dietetics at the University of Newcastle, highlighted case reports of thiamine (vitamin B1) and protein deficiencies occurring alongside scurvy in some anecdotes. She urged health systems to address this gap before deficiencies become widespread. Collins recommends that general practitioners’ chronic disease management plans for GLP-1 users routinely include referrals to dietitians, because when people are eating less, the quality of every bite matters more.
If you’re considering GLP-1 therapies, keep in mind:
- Talk with your clinician about personalized nutrition monitoring and whether a dietitian referral would be beneficial.
- Ensure your meals prioritize nutrient-dense foods to prevent vitamin and mineral gaps while calorie intake remains reduced.
- Be alert to signs of deficiency, such as fatigue, weakness, bruising, gum bleeding, or slow healing, and seek medical advice if they arise.
