Buying Guide
Dosage and Form
Vitamin D3 comes in various dosages, typically measured in IU (international units) or mcg.

Life Extension offers 5000 IU per softgel, making it a straightforward choice. Choose a form that fits your daily routine and dietary preferences.
Purity and Absorption
Not all vitamin D3 supplements are absorbed equally. Look for products that use high-quality, bioavailable forms. Life Extension sources its D3 from lanolin and includes a Certificate of Analysis for purity. Sports Research uses vegan-friendly lichen-derived D3 and combines it with coconut oil and vitamin K2 to improve absorption.
