Benefits
Everyday immune support
Supplies naturally sourced vitamin C from acerola, a nutrient that contributes to the normal function of the immune system. The whole-food format pairs vitamin C with plant polyphenols to support the body's routine immune defenses as part of a healthy diet.
Antioxidant and free-radical defense
Delivers a spectrum of polyphenols from berries, greens, green tea and turmeric that help neutralize free radicals and support the body's own antioxidant systems, helping maintain the balance between oxidants and antioxidants that everyday metabolism can disrupt.
Helps protect cells from oxidative stress
Vitamin C and accompanying plant compounds help protect cells and tissues from oxidative damage. In laboratory and early human testing the plant blend reduced several sources of reactive oxygen species, supporting healthy cellular function under oxidative load.
Whole-food alternative to synthetic vitamin C
Provides vitamin C alongside the phytonutrients, pigments and cofactors naturally present in fruits and vegetables, offering a food-derived option for people who prefer plant-sourced nutrients over isolated ascorbic acid at a modest daily serving.
Mechanism of action
Vitamin C as a physiological antioxidant and immune cofactor
Ascorbate from acerola acts as a water-soluble antioxidant that scavenges reactive oxygen species and regenerates other antioxidants such as vitamin E. It also serves as an enzymatic cofactor supporting the function and migration of neutrophils, lymphocytes and phagocytes in normal immune activity.
Polyphenol modulation of reactive oxygen species
Catechins, chlorogenic acid, curcuminoids and berry anthocyanins can quench free radicals directly and influence cellular oxidant-generating pathways. In human cells the related plant blend lowered mitochondrial, iNOS-dependent and NOX2-dependent ROS production, indicating activity beyond simple radical scavenging.
Support of endothelial nitric oxide
The polyphenol-rich core blend has been shown to raise circulating nitric oxide, a signaling molecule involved in vascular tone and immune signaling, suggesting the phytonutrients act on nitric-oxide-related redox biology and not only as passive antioxidants.
Clinical trials
Authoritative review of human and mechanistic evidence on vitamin C and immunity (Carr & Maggini, 2017, Nutrients). This is class evidence on vitamin C, the primary active that Phyto-C delivers from acerola, not a trial of the finished Phyto-C product.
Synthesis of human and mechanistic studies on vitamin C status and immune defense.
Vitamin C supports several parts of the immune system, including epithelial barrier function and the activity and clearance of immune cells; supplementation helps support immune defense, with the clearest benefit when dietary intake is low. Phyto-C is a whole-food vitamin C source, so this class evidence supports, rather than proves, an immune benefit of the finished blend.
Human study of a mixed fruit and vegetable concentrate on circulating antioxidants (Samman et al., 2003, Nutrition). Component/class evidence on whole-produce polyphenol blends, not a trial of the finished Phyto-C product.
Healthy adults given a mixed fruit and vegetable concentrate.
A whole fruit and vegetable concentrate raised plasma levels of several antioxidant vitamins, consistent with the idea that concentrated whole-produce blends can add to the body's antioxidant intake. This supports the antioxidant positioning of Phyto-C as a whole-food polyphenol and vitamin C source.
