    L-Glycine

    Why we chose it:

    L-Glycine is supported by an impressive amount of scientific research that shows its critical role in helping people support their collagen levels.

    L-Glycine has been shown to promote nervous system health and support an overall wellbeing.

    L-Glycine is also an excellent natural sleep aid. It promotes restful sleep and help maintain healthy sleep patterns. This means it may make it easier to fall asleep and stop waking up at night.

    Pureway Liposomal Vitamin C

    This is a unique, patented form of vitamin C is shown to have 233% higher absorption than other sources!

    Patented Prebiotic Fiber Preticx

    Prebiotic Fiber is superfood for the beneficial bacteria in your gut. It feeds them to support gut flora and promote balance of the microbiome. It perfectly matches the prebiotic bacteria in the Complete Gut Repair formula — because it’s been shown to support its growth in the gut.

    Why we chose it:

    Simply because it’s one of the best prebiotic fibers available right now. And this has been shown by a study from UCLA. In the study, the scientists found that PreticX effectively supports the gut microbiome

    What’s more, it’s been shown to go hand in hand with the prebiotic bacteria in the Complete Gut Repair formula to help promote regularity, nutrient absorption, and to help maintain blood sugar levels.

    This may translate to smooth digestion, increased energy, and amazing mood. Plus… it can help assist with weight loss.
