Shipping was very quick. And they haven’t pestered the hell out of me with emails.

Delivered quickly

I would buy this again. I really felt it worked.

These cute little tiny pills pack a big punch. Turns out I had "vampire" vitamin D levels (my words) after taking the test. Now I take my d.velop every night after dinner and feel great about keeping my immune system strong. Tiny pills are easy to swallow, app is super easy to use, test kit gave me powerful data about myself.

Taking supplements always feels like a guessing game but my d.velop subscription came with TWO tests so I could see my levels pre and post. I was low and then I wasn’t. The app is easy-to-use and I like the auto delivery so i can take “buy d” off my list of to-dos and make it an easy part of my daily routine.

No longer guessing about my VitaminD levels. As a woman of color, I always assumed I was deficient. This kit tells me my levels and replaces guesswork with science.

Retested in two weeks and was already in a good range. I will stay on this until upper range and then maintain going into the Fall.

Got my Vit D levels to optimal in no time! Feels good to have that extra protection as things get back to normal.

I’ve always had low vitamin D levels and I was previously taking Vitamin D3 spray as I’d heard that helps absorption. But I’d really been waiting for this product - I can’t believe it took so long for calcifediol to be on the market. I am really happy d.velop is here as now I know I’m taking the form of Vitamin D my body actually can use and benefit from fully. I also take the methylated form of folate for the same reason so it’s great to add this to my vitamin regimen.

I feel same and have remained healthy

Fast shipping .

Top quality vitamins and it also has a app that gives you a personal recommendations to boost your immunity!

The ordering process was seamless and the product arrived exactly when they estimated. I am super happy with the product so far - no impact to my stomach (which occurs sometimes with supplements). Now I am looking to expand to have the monthly subscription so I can have the supply to continue keeping my immunity strong! Thanks to the team for d.velop!

I was able to complete the shopping transaction within 1 minute.

Great solution for those with vitamin D deficiency!

I am excited about adding this fast acting supplement to my diet.

My Vitamin D levels needed a boost and this product did it!!

The packaging first off, is so convenient and compact- it's so much easier to keep track of the serving (and remembering to take it). The pills themselves are very small and easy to take. I love knowing that what I'm taking is actually efficient since D3 has become crucial to my daily routine.

My package arrived quickly and I have been taking the product for more than a week. I'm a person with Vit D deficiency and I'm so happy to find this product! Much better than taking the horse pills I have been taking to maintain my vitamin D levels. I'm thrilled to be on this new journey and looking forward to my next lab test results! So far... SO GREAT

Arrived promptly and well packed
