Supplements or medications should only be taken when they are genuinely essential, based on your current medical condition and confirmed through appropriate medical tests. Your body’s nutritional needs and overall health can change over time, so a prescription given a year ago may no longer be suitable. Taking them without updated medical advice could lead to unnecessary intake or possible side effects. It is always best to consult your doctor before restarting or continuing any supplement, ensuring the dosage and duration are tailored to your present health requirements.
