How does Metformin interact with dietary supplements like vitamins, minerals, or herbal products and what precautions should be taken?
1. Metformin can decrease vitamin B12 absorption; supplementing with B12 is advised. Monitor blood sugar if using herbs like ginseng.
2. Metformin may interact with calcium and vitamin D, altering their effectiveness. Ensure consistent monitoring of calcium levels when supplementing.
3. When taking metformin, avoid excessive alcohol in tinctures or herbal remedies as it may increase the risk of lactic acidosis.
4. Mixing metformin with iodine-containing supplements can affect thyroid function. Regular thyroid monitoring is recommended.
5. Be cautious with high-dose vitamin C or omega-3 supplements as they might impact blood sugar levels when used with metformin.
Metformin can reduce vitamin B12 absorption. Monitor B12 levels and consider supplementation if using metformin long-term. Also, alcohol can enhance metformin’s effect. Avoid excessive intake.
