Multivitamins can provide a broad spectrum of essential vitamins and minerals. They help fill nutrient gaps in your diet, support immune function, promote energy production, and maintain overall health.

Vitamin D is essential for bone health, immune function, and overall well-being. Many people have insufficient levels, especially those with limited sun exposure. Vitamin D supplements can help maintain proper levels.

Vitamin D helps the body absorb calcium from the intestines. When there is an excessive amount of vitamin D in the system, it can lead to elevated levels of calcium in the blood (hypercalcemia).

This can cause a range of symptoms, including nausea and vomiting, constipation, frequent urination, muscle and bone weakness, and kidney stones.

Vitamin B Complex including B1 (thiamine), B2 (riboflavin), B3 (niacin), B6 (pyridoxine), B12 (cobalamin), and folic acid (folate), are necessary for energy metabolism, nerve function, and the formation of red blood cells.

Note that most people can obtain all the B vitamins they need through a balanced diet. Excessive intake is more likely to occur when individuals take high-dose B vitamin supplements without a medical reason.

It could cause gastrointestinal problems, skin issues, nerve issues, a masking of other medical conditions, among others.

Calcium is vital for strong bones and teeth. Adequate calcium intake also supports nerve function and muscle contractions. Calcium supplements can be beneficial for those with a deficiency or those at risk of osteoporosis.

Excessive intake effects include altered electrolyte balance, impaired absorption of iron, zinc and magnesium, constipation, bloating and abdominal pain, and calcification of soft tissues.

Magnesium plays a role in over 300 biochemical reactions in the body. It supports muscle and nerve function, bone health, and helps regulate blood pressure and blood sugar levels.

Effects of excessive intake include gastrointestinal problems such as diarrhea, nausea, vomiting, and abdominal cramps, confusion, drowsiness, and lethargy, and low blood pressure.

Iron is necessary for oxygen transport in the blood and energy production. Iron supplements are commonly prescribed for individuals with iron-deficiency anemia, especially women of childbearing age.

Excessive intake of iron, can lead to a condition known as iron overload or iron toxicity. Iron overload can be particularly problematic because the body has limited mechanisms for excreting excess iron

Zinc is important for immune function, wound healing, and DNA synthesis. It may reduce the duration and severity of colds and support overall immune health.

Excessive intake results in impaired nutrient absorption, gastrointestinal problems and impaired immune function – among others.
