Best Time to Take Biotin
When should you take biotin for optimal benefits? Unlike some vitamins, biotin doesn’t cause drowsiness or excitability, so it can be taken any time of day. Consistency is key, either morning or night. For best absorption, take it with food containing fat.
Safety Considerations and Side Effects
Biotin is water-soluble, meaning that excess amounts are expelled through urine, which significantly reduces the risk of toxicity.
However, it's important to note that extremely high doses of biotin can interfere with certain lab tests, potentially leading to inaccurate or false results. For instance, biotin may affect tests that measure hormone levels, such as thyroid function tests, and can also alter the results of other diagnostic tests, including those for heart conditions.
Therefore, it is crucial to always inform your healthcare provider about your biotin supplementation, including the dosage you're taking, before undergoing any medical tests or procedures.
Conclusion
If you want to know how much biotin to take, start with your health goals. While the average adult requires 30 mcg daily, biotin supplementation is safe even at higher doses. Talk to your healthcare professional about your specific needs. For a natural boost, incorporate biotin-rich foods like eggs, salmon, cheddar cheese, and sweet potatoes into your diet. Your daily intake matters more than the timing, so whether you take it morning or night, consistency is key.
