g3 & ProBio PCC® Kit (USA)

g3 and ProBio PCC Kit — Superfruit Juice + Probiotic for Skin and Gut Health

The connection between gut health and skin health isn't just a wellness trend — it's backed by a growing body of scientific research. The gut-skin axis describes how the microbiome in your digestive system directly influences inflammation, immune function, and even skin conditions like acne, rosacea, and eczema. This kit pairs two powerful supplements: g3, a nutrient-dense superfruit juice from the gac fruit (Momordica cochinchinensis), and ProBio PCC, a clinically studied probiotic that supports digestive and immune health. Together, they address skin health from the inside out — something topical products alone can't fully achieve.

The gac fruit, native to Southeast Asia, has been called the "fruit from heaven" in Vietnamese cuisine, where it's traditionally reserved for special occasions. What makes it scientifically interesting is its extraordinary concentration of carotenoids — specifically lycopene and beta-carotene. Per gram, gac fruit contains up to 70 times more lycopene than tomatoes and 10 times more beta-carotene than carrots. These aren't just colorful pigments; they're powerful antioxidants that research has linked to reduced oxidative stress, improved skin elasticity, and protection against UV-induced cellular damage.

Key Benefits

• Antioxidant significantly boost — Gac fruit delivers exceptional concentrations of lycopene and beta-carotene
• Gut-skin axis support — ProBio PCC supports the microbiome connection between digestive and skin health
• Immune system support — Probiotics and antioxidants together support overall immune function
• Skin health from within — Carotenoids support skin elasticity and protection against oxidative damage
• Comprehensive wellness — Addresses multiple aspects of health: gut, skin, immune, and antioxidant status

Key Ingredients

This kit combines two distinct supplement technologies — superfruit nutrition and probiotic science.

• Gac Fruit (Momordica cochinchinensis) — in g3 juice — The gac fruit's nutritional profile is remarkable. It contains lycopene in a highly bioavailable form (bound to fatty acids, which enhances absorption), making it significantly more absorbable than lycopene from tomato-based sources. Beta-carotene, another key carotenoid, converts to vitamin A in the body — essential for skin cell turnover and repair. Research published in the International Journal of Food Sciences and Nutrition confirms gac fruit's exceptional antioxidant capacity.
• Probiotic Strain PCC (in ProBio PCC) — A clinically studied probiotic strain that supports beneficial gut bacteria, healthy digestion, and immune function. The gut microbiome influences systemic inflammation — and systemic inflammation is one of the key drivers of skin conditions including acne, rosacea, and premature aging. By supporting gut health, ProBio PCC addresses skin health at a foundational level that no topical product can reach.
• Additional Superfruits (in g3) — The g3 formula also includes cili fruit (one of the richest natural sources of vitamin C) and wolfberry (goji), adding further antioxidant and nutritional diversity to the blend.

What Makes This Formula Different

Most skincare approaches focus exclusively on what you put ON your skin. But dermatologists increasingly recognize that what happens inside the body — particularly in the gut — has a profound effect on skin health. Studies show that people with acne, rosacea, and eczema frequently have altered gut microbiomes compared to those with clear skin. By combining internal antioxidant nutrition (g3) with microbiome support (ProBio PCC), this kit addresses skin health at a level that no serum or cream can reach.

The gac fruit itself is relatively unknown in Western markets but has been a staple of Vietnamese traditional nutrition for centuries. Its lycopene bioavailability is a genuine scientific differentiator — most lycopene supplements use tomato-derived lycopene, which the body absorbs less efficiently because it's bound to different carrier molecules. Gac fruit's lipid-bound lycopene is absorbed more readily, meaning you get more active antioxidant per dose.

Combining these two products into a kit makes practical sense. Taking both a probiotic and an antioxidant supplement addresses two distinct but complementary pathways to skin health: internal microbiome balance and internal antioxidant protection. It's the supplement equivalent of a complete skincare routine — each component does something the other can't.

How to Use

g3 Juice: Take 60-120ml daily, either straight or mixed with water or another beverage. Best taken in the morning with breakfast — the fatty acid content in the gac fruit lycopene benefits from being consumed with food for optimal absorption. Refrigerate after opening. ProBio PCC: Take one capsule daily, preferably with a meal. Consistency is key — probiotic benefits build over weeks of regular use. Both products can be taken together as part of your morning routine for the simplest integration.

Best For

This kit is ideal for anyone who wants to support their skin health from the inside out — particularly people who experience persistent skin issues (dullness, breakouts, uneven tone) despite a solid topical skincare routine. It's also valuable for anyone looking to boost overall antioxidant intake, support gut health, or address the gut-skin connection. If you have specific digestive conditions (IBS, Crohn's), consult your gastroenterologist before starting a new probiotic.

Frequently Asked Questions

Q: How long before I notice skin improvements?

A: Gut microbiome changes typically become measurable within 2-4 weeks of probiotic use. Visible skin improvements from carotenoid supplementation usually appear around 6-8 weeks. The combination may show results sooner as both pathways work simultaneously.

Q: Can I take this alongside my topical skincare routine?

A: Absolutely — that's the ideal approach. Topical skincare addresses surface-level skin concerns, while these supplements address internal factors. They complement rather than compete with each other.

Q: What does g3 juice taste like?

A: It has a pleasant, slightly sweet tropical fruit flavor. Most people enjoy it straight, but it can be mixed with water or juice if preferred.

Q: Do I need to refrigerate these products?

A: Refrigerate g3 juice after opening. ProBio PCC capsules are shelf-stable but benefit from cool, dry storage. Don't leave either product in direct sunlight or extreme heat.

Q: Are there any side effects?

A: Most people tolerate both products well. When starting a probiotic, some people experience mild bloating or digestive adjustment for the first few days — this typically resolves within a week as your gut microbiome adjusts. If you're on medication, consult your doctor before starting any new supplement.
