Feeling constantly weak and sleepy for a year is not normal and requires medical evaluation. Before starting any supplements, it is crucial to identify the root cause. These symptoms often stem from conditions like anaemia (low iron), vitamin D or B12 deficiency, or thyroid issues. I strongly recommend visiting a doctor for basic blood tests, including a Complete Blood Count (CBC), thyroid panel, and vitamin levels. Self-medicating with random energy supplements might mask a serious underlying issue or cause harm. Once we have your test results, we can prescribe the exact medicine or targeted supplements you need to safely regain your energy.
