The Importance of Taking Supplements Correctly

If you're going to take a supplement, you need to ensure you're taking it correctly. Monitoring your levels and reassessing the risk and benefits regularly is crucial. This applies to all supplements, including Vitamin D.

Four Common Mistakes When Taking Vitamin D

1. Not Taking the Right Amount

The most common mistake is incorrect dosing. The Recommended Daily Allowance (RDA) for most adults is 600-800 IU, but if you are deficient, you may need significantly more. The only way to determine your needs is through a blood test from your doctor.

2. Taking Vitamin D on an Empty Stomach

Vitamin D is a fat-soluble vitamin, meaning it absorbs best when taken with fatty foods such as avocados and nuts. Taking it on an empty stomach can limit its effectiveness.

3. Not Reassessing Your Levels

Your Vitamin D needs can change based on factors like seasons, weather, diet, and activity levels. You should check your levels every 6 to 12 months and adjust your dosage accordingly.

4. Assuming All Vitamin D Supplements Are the Same

Not all Vitamin D supplements are created equal. There are two primary forms:

  • Vitamin D2

  • Vitamin D3 (the most effective, bioavailable, and absorbable form)

Taking BioEmblem Vitamin D3 ensures better absorption and effectiveness.

Optimizing Your Supplement Routine

To get the most out of your Vitamin D supplement, follow these key steps:

  • Take the correct dosage based on blood tests.

  • Consume it with fatty foods for better absorption.

  • Monitor and adjust your levels periodically.

  • Choose high-quality supplements like BioEmblem Vitamin D3
