While deficiencies are a concern, excessive intake of calcium and vitamin D can also pose health risks. Hypercalcemia (too much calcium) can lead to kidney stones, abdominal pain, and altered mental status. Excessive vitamin D can result in hypercalcemia as well and may cause nausea, vomiting, and weakness. It's important to adhere to recommended dosages and consult with a healthcare provider before starting any supplements.
