Science & Safety
Many companies claim they have the best manufacturing dietary supplement technology without offering any scientific evidence.
At 2x4, it’s about science. We’ve conducted many studies proving that our supplements are safe and perform exceptionally well. Currently, we have multiple ongoing clinical trials and will continue to invest in science to support our Nutristack® Liposomal Technology and the health of our consumers.
