Product Description

Vitamin AD Softgel — A:D Ratio Expertise for Brands That Care About Results

The #1 Question We Get From New Clients

"What A:D ratio should I use for my brand?"

It's the question most suppliers dodge. They give you a table of standard ratios and leave you to figure out the rest.

Here's the truth: Vitamin A and D are both fat-soluble. In the same softgel, they compete for the same absorption pathway. Get the ratio wrong, and one overwhelms the other.

That's why our formula team starts every Vitamin AD project by asking: Who is the end consumer? A children's brand needs a different balance than a bone-health supplement for seniors.

We don't just fill your order. We help you choose the right formula.
