What the experts are saying

“Vitamin D is a foundational immune system nutrient. It’s important that we assess our supplemental needs as we look to stay healthy year round.”

Registered Dietitian,

“More than 9 in 10 people don't get enough vitamin D from food alone. That's why we created the most effective vitamin D available as a supplement.”

Chief Science Officer,
Nate Matusheski PhD

"With so much misinformation out there, especially online, I think it's invaluable that users have access to an RD to help navigate how to improve their immune health in a way that is tailored specifically to them."

The science behind d.velop™

The vitamin D used in d.velop™ is a special form, called calcifediol (kal'' sif e dye' ol). That's the form of vitamin D found naturally in your blood. This means your vitamin D levels increase 3x faster than with regular vitamin D3.*† Given the importance of vitamin D for immune health, there are real benefits to optimizing your vitamin D levels quickly!*
