Is it normal to feel tired and sick after taking magnesium glycinate for the first time?

It isn’t typical to experience tiredness, grogginess, or feeling sick from taking magnesium glycinate, especially from just a 100mg dose. Magnesium glycinate is often well-tolerated and is generally used to supplement magnesium levels or address deficiencies without many side effects at regular doses. However, everyone can react differently. Your symptoms might be related to several factors, including dehydration from increased urine output since this could lead to electrolyte imbalances. If you aren’t used to high levels of fluid loss, then replacing lost electrolytes and fluids is important. Drinking water and ensuring a balanced diet with essential electrolytes like potassium and sodium could help alleviate these symptoms. It’s worth considering if the supplement might have interacted with other medications or if you ate or drank anything unusual recently. If your symptoms persist or worsen, it would be wise to consult a healthcare provider to rule out other possible causes such as underlying health concerns, which could be unrelated to the supplement. Prioritize medical attention if you notice severe or sudden changes in your health, especially if you develop symptoms like dizziness, confusion, or continuous vomiting. In the meantime, pausing this supplement until you get professional advice could be reasonable to avoid potential exacerbation of your symptoms.
