Fatigue on a GLP-1 does not usually mean the medication is failing. It usually means your intake of a handful of key nutrients has quietly dropped below where it needs to be.
The four suspects
1. B-vitamins
B1, B2, B3, B6, B12, and folate are cofactors in the machinery that turns food into ATP. Eat less food, and you get less of these. The methylated forms bypass an extra conversion step your body would otherwise have to do.
2. Iron (if you are premenopausal)
Iron is not in Daily Foundation because it is highly individual and can be harmful in excess. If your energy has crashed and you are premenopausal, ask your doctor to check ferritin, not just hemoglobin.
3. Sodium, potassium, and magnesium
You are eating less food, which means less salt and fewer mineral-rich foods. Low sodium and low potassium show up as fatigue, dizziness, and headaches, long before they look dramatic on a lab report.
4. Vitamin D
What to do
- Hit your protein target. Fatigue on under-eating is fatigue.
- Add electrolytes daily. Sodium 300 mg, potassium 300 mg, magnesium 100 mg is a reasonable floor.
- Use active-form B-vitamins if you are getting less from food.
- Confirm vitamin D status with a lab if it has been a year or more.
Daily Foundation was built to cover items 2 and 3 in one scoop, at doses the research uses.
