Clinical Evaluation of an NVTIA GABA-Lysine Calcium Preparation for Promoting Calcium Absorption
Abstract
Background: Improving calcium bioavailability requires more than simply increasing elemental calcium content. In this study, we evaluated an NVTIA GABA-lysine calcium preparation that couples a modified algal-calcium microsphere, an absorption-promoting inclusion module, a calcium-deposition cofactor module, and antioxidant protection. We then matched our bench findings with published human trials that are directly relevant to lysine-assisted calcium handling, algae-derived calcium, calcium plus vitamin D, and vitamin K-guided mineral utilization. Methods: We summarized our bench dataset on active retention, simulated intestinal dispersion, gastric-acid integrity, particle-size distribution, and short-term stability. We then incorporated published human studies on L-lysine and calcium metabolism, calcium lysinate, active absorbable algal calcium, marine algae-derived calcium, calcium plus vitamin D, vitamin K2 add-on therapy, and casein phosphopeptide-containing calcium preparations. Results: In our bench dataset, core active retention reached 98.5%–99.0% versus 82.3% in the comparator, K2MK7/VD2 retention reached 98.5%–98.8% versus 86.7%, and complete dispersion in simulated intestinal fluid occurred within 2–3 minutes versus >8 minutes in the comparator. Published human evidence showed that L-lysine supplementation increased intestinal calcium absorption and improved renal calcium conservation in osteoporotic patients; calcium lysinate achieved a reported relative oral…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
