Our Science

Why experts go with d.velop

“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,
Chloe Giraldi, MS, RD, LDN

“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."

We recommend that you take d.velop™ on a daily basis, alongside food. You might find taking d.velop at the same time each day helps you get in the habit. Remember, dietary supplements are not intended to replace a healthy diet, but they can help support one!
Clinical studies have shown that ampli-D® can achieve optimal vitamin D status (30ng/mL), on average 3X faster, and is 3X more effective compared to the same mcg dose of traditional vitamin D3.
d.velop™ products are as safe as other vitamin D products for pregnant and lactating women. However, we recommend that you consult with your doctor before using or continuing to use d.velop™ and any other dietary supplement if you are nursing, pregnant, trying to conceive, or taking medication.
