Are you going to wholesale hibiscus sabdariffa extract from a professional hibiscus sabdariffa extract producer and supplier? it is one of the well-known hibiscus sabdariffa extract manufacturers in China, welcome to contact our factory.

Hibiscus sabdariffa Extract (VC-H1^®) is a plant-based ingredient derived from the calyces of organic hibiscus, commonly known as roselle. Unlike conventional plant extracts, roselle extract is produced through a proprietary enzymatic hydrolysis process that breaks down the plant's natural extensin (a glycoprotein) into low-molecular-weight peptides. This process creates a profile of di- and tri-peptides that is remarkably similar to human type I collagen, featuring key amino acids glycine, proline, and hydroxyproline in comparable levels. This innovative approach, which earned the Grand Prix at SIAL Paris 2022, positions VC-H1^® as the world's first true plant-based collagen alternative.

Advantages of VC-H1^®

HSF's expertise in plant-based peptide technology is built on years of dedicated research and innovation.

1. True Plant-Based Collagen Alternative

VC-H1^® is the world's first plant-based ingredient that delivers a peptide profile nearly indistinguishable from animal-derived collagen. By enzymatically hydrolyzing the glycoprotein from organic hibiscus, it creates low-molecular-weight di- and tri-peptides that provide the essential amino acids-glycine, proline, and hydroxyproline-in a human-identical structure. This allows the body to recognize and utilize it as true "collagen" for skin structure and elasticity.

2. Overwhelming Absorption with Ultra-Low Molecular Weight

The key to collagen's efficacy is its size. Hibiscus sabdariffa Extract features an ultra-low molecular weight of under 500 Da, far smaller than conventional animal collagen. This allows it to be rapidly absorbed in the intestine as di- and tri-peptides, reaching the dermis to reinforce the skin's structural network effectively.

3. Superior Efficacy at a Lower Dose

Clinical and preclinical studies demonstrate that despite being applied at a 2.5-fold lower concentration than animal collagen, VC-H1^® shows significantly higher rates of intracellular collagen synthesis. Its low effective dose of 1.5g/day, compared to 5-10g for animal collagen, enables cost-neutral replacement and provides greater formulation flexibility.

4. Visible Beauty Transformation

The efficacy of VC-H1^® is backed by robust scientific evidence:

Human Clinical Study: A randomized, double-blind, placebo-controlled trial on 100 participants aged 35-59 demonstrated significant improvements in skin hydration, elasticity, and wrinkle reduction.

Preclinical Study (In-Vivo): In a UVB-induced photoaging mouse model, VC-H1^® significantly reduced wrinkle depth, skin roughness, and expression of collagen-degrading enzymes (MMP1, MMP3), while enhancing genes for hyaluronic acid and collagen production.

Preclinical Study (In-Vitro): Compared to four types of animal collagen, VC-H1^® demonstrated the highest collagen production capacity even at a 2.5 times lower concentration, indicating superior efficacy.

5. Double Care: Collagen Synthesis + Antioxidant Protection

Unlike animal collagen, Hibiscus sabdariffa Extract provides dual benefits. It not only stimulates collagen synthesis but also delivers abundant polyphenols and flavonoids from organic hibiscus, which act as powerful antioxidants to protect the skin from UV rays and oxidative stress.

6. Clean, Sustainable, and Ethically Sourced

Hibiscus sabdariffa Extract is 100% plant-based, vegan, and derived from organically grown hibiscus. It is certified halal, kosher, and non-GMO, addressing consumer concerns over animal-borne diseases, antibiotics, heavy metals, and the characteristic fishy odor of traditional collagen.

Product Functions

Supports Collagen Synthesis & Skin Structure: Provides the precise amino acid building blocks (glycine, proline, hydroxyproline) to stimulate the body's own collagen production, improving skin elasticity, density, and firmness.

Promotes Skin Hydration: Enhances the expression of genes involved in hyaluronic acid synthesis, leading to increased skin moisture and reduced transepidermal water loss.

Reduces Visible Signs of Aging: Clinically proven to decrease wrinkle depth, skin roughness, and improve overall skin texture and smoothness.

Provides Potent Antioxidant Protection: The natural polyphenols and flavonoids in hibiscus help neutralize free radicals, protecting the skin from UV-induced damage and preventing collagen breakdown.

Supports Overall Skin Health: Improves the keratin index and skin barrier function, contributing to a healthier, more radiant complexion.

Applications

The versatility of Hibiscus sabdariffa Extract as a water-soluble powder with a neutral taste enables a wide range of applications across the nutraceutical, food, and beverage industries:

Dietary Supplements:

Powders, stick packs, and sachets for beauty-from-within formulas

FAQ

Q1: What is VC-H1^® and how is it different from animal collagen?

A1: VC-H1^® is a plant-based collagen alternative derived from organic hibiscus. Unlike animal collagen, it is a hydrolyzed plant glycoprotein that provides a peptide profile and amino acid composition nearly identical to human collagen. It is vegan, sustainable, free from animal-borne disease risks, and has a neutral taste.

Q2: How does VC-H1^® work?

A2: VC-H1^® works by providing essential di- and tripeptides (specifically glycine, proline, and hydroxyproline) that serve as building blocks for the body's own collagen synthesis. Its ultra-low molecular weight (<500 Da) ensures superior absorption, enabling it to effectively stimulate fibroblast activity and promote collagen production in the skin's dermis.

Q3: What is the recommended daily dosage of Hibiscus sabdariffa Extract?

A3: The clinically studied and recommended dosage for roselle extract is 1.5 grams per day. This low dose is a key advantage over animal collagen, which typically requires 5-10 grams daily, enabling cost-effective formulation and a better user experience.

Q4: Is VC-H1^® backed by scientific research?

A4: Yes, VC-H1^® has been validated through rigorous scientific studies, including:

A randomized, double-blind, placebo-controlled human clinical trial showing significant improvements in skin hydration, elasticity, and wrinkle reduction.

Preclinical in vivo studies demonstrating anti-photoaging and collagen-boosting effects in a UVB-induced aging model.

Preclinical in-vitro studies confirming its ability to produce collagen more effectively than several types of animal collagen at a lower concentration.

Q5: What certifications does VC-H1^® have?

A5: VC-H1® holds a comprehensive suite of certifications, including: Vegan, Halal, Kosher, Non-GMO, Organic, GMP, HACCP, ISO 9001, and ISO 22001, ensuring it meets the highest standards for quality, purity, and ethical production.

Q6: Is VC-H1^® suitable for use in clear beverages?
