Abstract
By Beth’s Wattle & Plum C+ Collagen blend harnesses the power of native Australian botanicals, particularly Davidson plum, to deliver a rich, natural source of vitamin C. This article explores the scientific basis for the formulation, highlighting the role of vitamin C in collagen synthesis, skin protection, and gut barrier function. We review relevant clinical studies and biochemical pathways to provide a clear understanding of how this blend supports beauty and wellness from within.

Introduction
Vitamin C (ascorbic acid) is a critical nutrient involved in numerous physiological functions, including collagen biosynthesis, antioxidant defense, and immune support. While synthetic vitamin C is widely available, the bioavailability and added phytonutrients in natural sources such as Davidson plum (Davidsonia jerseyana) may offer enhanced benefits. By Beth’s Wattle & Plum C+ Collagen combines premium bovine collagen with native botanicals to deliver a synergistic formula designed to support both skin health and gut integrity.

Vitamin C and Collagen Synthesis
Vitamin C is an essential cofactor for prolyl and lysyl hydroxylase, the enzymes responsible for stabilizing and cross-linking collagen fibers. Without adequate vitamin C, newly synthesized collagen is structurally weak, leading to signs of skin aging such as fine lines, wrinkles, and reduced elasticity.

Clinical evidence supports this relationship:

• A double-blind, placebo-controlled study (Pullar et al., 2017, Nutrients) demonstrated that daily supplementation with vitamin C significantly improved skin hydration, elasticity, and density over 12 weeks.

• A 2015 study in Clinical, Cosmetic and Investigational Dermatology (Campos et al.) found that oral supplementation with vitamin C and other antioxidants reduced oxidative stress markers and improved the clinical appearance of photoaged skin.

Davidson plum is a standout source, delivering up to 100 times more vitamin C than an orange, providing a potent natural boost for collagen formation (Australian Native Food & Botanicals, 2020).

Antioxidant Protection and Skin Radiance
Vitamin C functions as a potent antioxidant, scavenging free radicals generated by UV exposure, pollution, and internal metabolic processes. These reactive oxygen species (ROS) contribute to collagen breakdown and hyperpigmentation.

• A study published in The American Journal of Clinical Nutrition (Cosgrove et al., 2007) showed that higher dietary vitamin C intake was associated with a lower likelihood of wrinkled appearance and dryness in middle-aged women.

• Topical and oral vitamin C has been shown to inhibit melanogenesis and reduce pigmentation irregularities (Farris, 2005, Dermatologic Surgery).

The polyphenols and anthocyanins in Davidson plum further enhance its antioxidant profile, offering synergistic skin protection beyond vitamin C alone.

Vitamin C and Gut Barrier Integrity
Emerging research highlights vitamin C’s role in supporting gut health. Vitamin C contributes to tight junction integrity, helping to maintain the mucosal barrier and reduce intestinal permeability.

• A 2014 animal study (Lobo et al., Journal of Nutritional Biochemistry) demonstrated that vitamin C supplementation improved tight junction protein expression and reduced gut permeability in models of oxidative stress.

• Oxidative stress is known to impair gut barrier function; vitamin C’s antioxidant properties mitigate this damage and support a healthy microbiome environment (Camuesco et al., 2004, Gut).

This is particularly relevant for individuals experiencing symptoms of leaky gut or low-grade inflammation, as a stronger gut barrier reduces systemic inflammation and supports overall wellness.

Conclusion
By Beth’s Wattle & Plum C+ Collagen blend offers a science-backed solution for consumers seeking holistic beauty and gut support. The vitamin C content from Davidson plum not only enhances collagen production for smoother, firmer skin but also helps fortify gut barrier function. Combined with premium bovine collagen, this formulation represents a comprehensive approach to internal and external health.
