When you’re expecting, ensuring you get the right nutrients is crucial for the healthy development of your baby. It might be tempting to take a multivitamin along with other supplements, but it’s important to be cautious. Excessive intake of vitamins can lead to an overdose, especially when combining multiple supplements or taking higher doses than recommended.
While any vitamin can become toxic at high levels, calcium and iron are particularly concerning when consumed in excess. Taking a prenatal multivitamin is essential, but it’s wise to consult your healthcare provider before adding any extra supplements to your routine. This will help you avoid the risks of overdosing.
Key Terms to Understand:
- Tolerable Upper Intake Level (UL): The highest daily amount of a vitamin that poses no risk of adverse health effects.
- Adequate Intake (AI): A recommended intake level based on observed or experimentally determined estimates.
- Vitamin Toxicity: Occurs when someone takes megadoses of vitamins such as A, B, C, D, or niacin.
