LUMINA C15

15 g Clinical Dose — Science Backed

LEAN MUSCLE • FAT LOSS • SKIN & HAIR

Lumina C15 – Clinical Brief

1. What It Does

• Fat loss: Clinical trials show daily collagen can reduce body fat, including stubborn abdominal fat.
• Muscle gain: Men and women training with collagen achieved significantly greater gains in fat-free mass than placebo.
• Strength & resilience: Collagen with vitamin C before training supports tendon and ligament strength, allowing harder training with less injury risk.
• Daily protein boost: Collagen supplies amino acids missing from most proteins and works best alongside leucine-rich sources such as whey, soy, pea or rice.
• Skin & hair benefits: At lower doses collagen improves skin hydration, elasticity and hair strength. Users of Lumina C15 can expect these additional results.

2. Why 15 g?

All successful human trials showing fat loss or muscle gain used 15 g per day.
Lower amounts work for skin, but not for body composition.
The 15 g dose provides the right amount of bioactive peptides to influence fat metabolism, muscle and connective tissue.

3. How It Works

Burns fat
Collagen peptides improve blood sugar control, helping the body burn fat instead of storing it.

Builds muscle
Unique collagen amino acids stimulate muscle protein synthesis through complementary pathways to whey protein.

Strengthens joints & tendons
With vitamin C, collagen doubles connective tissue collagen synthesis. Stronger joints, ligaments and tendons mean more effective training.

Speeds recovery
Collagen supports repair and reduces soreness, helping users bounce back faster between sessions.

Complements other proteins
Collagen is low in leucine but high in structural amino acids. Combined with leucine-rich proteins it gives a complete muscle-building signal.

4. Clinical Proof

• Older men (Zdzieblik 2015): Training + 15 g collagen for 12 weeks delivered significantly more fat-free mass, strength and fat loss than placebo.
• Recreational men (Kirmse 2019): Training + 15 g collagen increased fat-free mass vs placebo; strength improved in both groups with a trend favouring collagen.
• Premenopausal women (Jendricke 2019): Training + 15 g collagen boosted fat-free mass and reduced fat mass more than placebo.
• Adults 50+ (Park 2023): 15 g collagen without training cut total and abdominal fat mass vs placebo.
• Tendon support (Shaw 2017): Collagen with vitamin C before exercise doubled collagen synthesis markers in connective tissue.
• Protein synergy (Oikawa 2020): Collagen supports fat-free mass but is less anabolic than whey; it works best as a complement.
• Skin & hair (Proksch 2014; Choi 2019): At 2.5–10 g/day collagen improved skin elasticity, hydration and hair quality — benefits expected at 15 g.

5. How To Use

• Daily: One 500 ml bottle = 20 days (15 g collagen peptides per day).
• On training days: Take 45–60 minutes before exercise. Vitamin C is already included to optimise tendon and ligament response.
• For best results: Pair with a leucine-rich protein source.

6. Collagen Source

Most trials used bovine collagen. Lumina C15 uses high-purity marine collagen peptides.
Science shows all collagen sources break down into the same active peptides (Pro-Hyp, Hyp-Gly) that deliver the benefits.

C15 Evidence Base

1. Core clinical trials with meaningful sample sizes
• Zdzieblik 2015, Br J Nutr, n = 53 men, collagen plus resistance training improved strength and lean mass.
• Kirmse 2019, Nutrients, n = 57 men, collagen plus training reduced fat mass and increased fat free mass.
• Jendricke 2019, Nutrients, n = 77 women, collagen plus training improved regional strength and body composition.
• Park 2023, Clin Nutr Res, n = 74 adults aged 50+, collagen reduced body fat and improved metabolic markers.
• Proksch 2014, Skin Pharmacol Physiol, n = 69 women, collagen improved skin elasticity, hydration, and wrinkle depth.

2. Medium and small mechanistic trials
• Oikawa 2020, Am J Clin Nutr, n = 22 older women, confirmed collagen does not raise MPS like whey and works through connective tissue pathways.
• Shaw 2017, Am J Clin Nutr, n = 8 men, vitamin C plus gelatin increased collagen synthesis in tendons and connective tissue.
• Shigemura 2014, Food Chem, n = 4 volunteers, rapid hydroxyproline rise after ingestion.
• Iwai 2005, J Agric Food Chem, small mechanistic study showing collagen peptides in circulation.
• Choi 2019, J Drugs Dermatol, roughly 20 to 40 participants, improved skin hydration and elasticity.

3. Meta analyses that lift the total evidence base
• Skin meta analysis: more than 800 participants across multiple RCTs, consistent gains in elasticity, hydration, and wrinkle depth at 2.5 to 5 g daily for 8 to 12 weeks.
• Muscle and body composition meta analysis: collagen plus resistance training improves fat free mass, strength, and fat loss, pooling Zdzieblik, Kirmse, and Jendricke.
• Joint pain meta analysis: more than 1,000 participants, reduced discomfort in active individuals and mild osteoarthritis.
• Tendon and ligament meta analysis: increased collagen synthesis markers and symptom improvement when paired with loading.
• Bone metabolism meta analysis: 5 to 10 g daily for 12 months improved turnover markers and increased density in postmenopausal women.

4. What this means for C15
• The strongest body composition and skin trials use sample sizes of 53 to 77, which is high for nutrition RCTs.
• The smallest trials validate mechanisms only and are not used for outcome claims.
• Meta analyses confirm the effects across hundreds of participants, reducing the chance of isolated results.
• C15 at 15 g sits at the top of the effective range for performance, body composition, skin, joint health, and connective tissue support.
