This lady comes to hospital with fatigue, muscle weakness etc and we found out she had hypothyroidism (low thyroid hormone levels) and was started on thyroid hormone replacement
A few months later her hormone levels were still low despite optimising her meds. While reviewing her meds we discovered, a friend had recommended a calcium based supplement to boost her energy
Calcium reduces the absorption of levothyroxine in your gut and should not be taken at the same time. The supplement she was taking interfered with the treatment of her underlying condition
Before starting any meds or supplements please talk to your primary care doctor or pharmacist
