"Understanding the Dangers of Overdosing on Popular Supplements"

Dietary supplements, including popular ones like fish oil and vitamin D, can be harmful if taken in excessive amounts. Overdosing on magnesium can lead to symptoms like sleepiness, loss of reflexes, and even paralysis and death, while too much vitamin C can cause tiredness, kidney problems, and vitamin B12 deficiencies. Excessive vitamin D intake can increase blood calcium levels, leading to symptoms like conjunctivitis, pain, fever, and vomiting, especially for those with kidney disease. The main risk associated with fish oil supplements is the potential presence of pollutants like heavy metals, although processing and purification typically remove these toxins. It's important to be cautious and consult a healthcare professional before taking dietary supplements.
