LM1019 Enhances Natural Killer Cell Activity in Defined Adult Subsets: A Double-Blind, Placebo-Controlled Trial.

Probiotics offer a non-pharmacological approach to support immune function, yet clinical evidence for strain-specific benefits remains limited. We conducted an 8-week, randomized, double-blind, placebo-controlled trial of LM1019 in 121 generally healthy adults. Both the active and placebo arms produced comparable within-group increases in natural killer (NK) cell cytotoxicity and modest, non-differential declines in circulating cytokines; safety and tolerability were excellent, with mild adverse events evenly distributed.

A 12-Week, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of LMT1-48 on Body Fat Loss.

Objectives: This study aims to evaluate the efficacy and safety of probiotics for body fat reduction in obese individuals.

Methods: A total of 106 participants with a body mass index between 25 and 30 kg/m were randomly assigned to either the experimental group treating with LMT1-48 or the placebo group in the placebo-controlled clinical trial. Body composition was assessed by dual-energy X-ray absorptiometry and computed tomography.

Effect of Heat-Treated nF1 on the Immune System Including Natural Killer Cell Activity: A Randomized, Placebo-Controlled, Double-Blind Study.

Heat-treated nF1 (HT-nF1) increases immune cell activation and the production of various immunomodulators (e.g., interleukin (IL)-12) as well as immunoglobulin (Ig) G, which plays an important role in humoral immunity, and IgA, which activates mucosal immunity.

Oral consumption of Bonito fish-derived elastin peptide (VGPG Elastin ) improves biophysical properties in aging skin: A randomized, double-blinded, placebo-controlled study.

Background: Recent in vitro and in vivo studies have suggested that the elastin peptide improves the skin's biophysical properties, enhancing the proliferation of fibroblasts and elastin synthesis, resulting in anti-aging properties. Therefore, we conducted a randomized, double-blinded, placebo-controlled study to clinically evaluate the effect of elastin peptide intake on human skin.

Materials And Methods: Healthy adult participants (N = 100) were randomly assigned to receive a test product containing 100 mg of Bonito elastin peptide (VGPG Elastin ) or placebo.

Low-molecular-weight collagen peptides supplement promotes a healthy skin: A randomized, double-blinded, placebo-controlled study.

Background: Oral collagen peptides supplementation was reported to improve skin integrity and counteract skin aging.

Aims: A randomized, double-blinded, placebo-controlled study was conducted to clinically evaluate the impact of low-molecular-weight collagen peptides on the human skin.

Patients/methods: Healthy adult participants (n = 100) were randomly assigned to receive a test product containing low-molecular-weight collagen peptides or a placebo.

Topical Application of Peptide Nucleic Acid Antisense Oligonucleotide for MMP-1 and Its Potential Anti-Aging Properties.

Matrix metalloproteinase-1 (MMP-1) is a zinc-containing endopeptidase that degrades dermal collagen and other extracellular matrix molecules. It is recognized as one of the most important indicators of cellular senescence and age-related skin changes. Here, we introduced a novel MMP-1 peptide nucleic acid (PNA) derivative--which can interact with and consequently silence the MMP-1 gene sequence.
