Scientific Validation & Studies
At G.A.P, every ingredient is validated by science, third-party tested, and batch verified. That means no fillers, no artificial sweeteners and no cheap shortcuts. Just the good stuff, done right. Scroll down to our Scientific Validation & Studies section to see the peer-reviewed research behind our key ingredients: Amino9® and Naticol®.


Amino9®
Essential Amino Acid Efficacy
Clinically validated to match whey protein in supporting muscle protein synthesis and recovery – even at low doses. Supported by sports nutrition consensus statements and randomised studies.
- Muscle Protein Synthesis (MPS): A clinical summary in Clinical Nutrition showed that Amino9® can stimulate MPS at levels comparable to whey protein, thanks to its leucine-rich profile—even small doses (1.5 g EAAs with 0.6 g leucine) had significant anabolic effects. Read More
- Foundational Research on EAAs: Broader studies reinforce that a complete 9-EAA profile (not just isolated BCAAs) is critical for maximising muscle protein synthesis and maintaining muscle mass, especially when combined with resistance exercise. Read More
- Expert Consensus: The International Society of Sports Nutrition (ISSN)
confirms that EAA supplementation – particularly full-spectrum free-form blends – support exercise performance and muscle maintenance. Read More


Naticol® Marine Collagen
Backed by Clinical Evidence
Proven to improve skin elasticity, hydration, and wrinkles; reduce joint discomfort; and support muscular strength and lean mass, especially in older adults. Designed with low-molecular-weight peptides for exceptional absorption.
- Skin Health & Anti-Aging: Multiple double-blind, randomised, placebo-controlled trials found that daily intake of Naticol® significantly improved skin firmness, elasticity, wrinkle appearance, and hydration at doses ranging from 2.5 g to 10 g per day over several weeks. Read More
- Joint & Osteoarthritis Support: An 8-week pilot study involving Naticol® (10 g/day) showed meaningful improvements in knee osteoarthritis symptoms, including reduced pain and better functional mobility (via WOMAC scores). Read More
- Muscle Mass & Function in the Elderly: A 24-week randomized, placebo-controlled study demonstrated that daily 15 g Naticol® supplementation significantly increased lean muscle mass and physical performance (grip strength, chair-stand, and short physical performance battery tests) in seniors experiencing sarcopenia.
