FAQs.
How are your supplements made with up to 149× better absorption?
We uniquely formulate each supplement using a combination of absorption-enhancing technologies, such as liposomes and advanced nano-delivery systems. We don’t rely on a single method. Instead, we select and layer multiple techniques based on the specific ingredient and how the body best absorbs it.This approach allows us to create pharmaceutical-grade supplements designed for significantly improved bioavailability, delivering up to 149× better absorption.
Can I combine this with my current supplement routine?
This varies with each of our products. We always suggest you consult your doctor and make sure you are not exceeding the recommended daily values of nutrients.
Is this safe to take while breastfeeding or pregnant?
When taking a supplement of any kind during pregnancy or breastfeeding, we recommend consulting a physician and showing them our nutritional labels to make the best decision for you.
Are your products safe and third-party tested?
Yes, all of our products are produced in GMP and NSF certified facilities and undergo third-party testing to verify quality and consistency. While dietary supplements are not evaluated by the FDA for disease diagnosis or treatment, we stand behind their safety and transparency, with rigorous testing on every batch.
What makes your brand different than other supplements?
Our supplements are designed for significantly improved absorption using advanced delivery technologies that help nutrients enter your system more effectively. Unlike many traditional supplements where a large portion isn’t absorbed, our formulations use proprietary methods like nanoparticle technology and liposomes to enhance bioavailability, helping you get more benefit from every dose.
