Overview
- Vicki McFarlane says she began Mounjaro in January 2025 and lost about 2st 3lbs in two months before stopping because of severe nausea, headaches and persistent 'eggy burps'.
- After quitting the injections she tried slow-release berberine patches bought online and reports losing 3st 7lbs from June 30, 2025 to October 14, 2025 as her evening sugar cravings disappeared.
- She resumed berberine in tablet form three weeks before this coverage and reports a further 10lb loss, while her husband also said he felt rapid appetite suppression when he tried the supplement.
- The story contrasts costs — roughly £180 a month for Mounjaro versus berberine products sold for about £8.99 per pack — and notes the supplement is sold as an unregulated product on retail sites.
- Experts quoted in the coverage caution that berberine is not a licensed weight-loss medicine, has mixed clinical evidence for metabolic effects, can cause gut symptoms and can interact with some drugs, so medical advice is advised.
