Vitamin C(liposomal)
Ingredient research · Vitamin C
Vitamin C is an essential water-soluble nutrient that supports collagen production, antioxidant defenses, and the normal function of immune cells. Supplementation reliably prevents or corrects deficiency, can improve absorption of plant-based iron, and may modestly shorten the duration of common colds when taken regularly.
- Supports lower common-cold risk during brief periods of severe physical exercise or cold stress.
- Supports circulating Vitamin C status across studied healthy and clinical populations.
- Supports short-term blood-pressure and endothelial-function outcomes in studied adults.
- Supports fasting-glucose and HbA1c outcomes in adults with type 2 diabetes.

Palmitoylethanolamide(liposomal)
Ingredient research · Palmitoylethanolamide
Palmitoylethanolamide is a naturally occurring fatty-acid signaling molecule that helps regulate inflammatory and pain responses, partly by influencing mast cells and nerve-supporting glial cells. As a supplement, it may reduce some types of chronic or neuropathic pain, with possible relevance to inflammatory discomfort and nerve health.

Hyaluronic Acid(liposomal)
Ingredient research · Hyaluronic Acid
Hyaluronic Acid is a water-binding molecule naturally abundant in skin, joints, and other connective tissues, where it helps maintain hydration and lubrication. Oral supplements may modestly improve skin moisture and elasticity and can support joint comfort, though effects depend on the formulation and individual.
