A Pilot Study to Evaluate the Ability of Lactoferrin to Modulate Iron Homeostasis and Exercise Performance in Exercising Females

This randomized, double-blind, active-controlled trial will evaluate the effects of human lactoferrin supplementation combined with low-dose iron on iron status, aerobic performance, and lactate metabolism in exercising women with low ferritin. Approximately 30 healthy, menstruating women aged 18-45 years with serum ferritin \<35 µg/L will be enrolled in an 8-week intervention. Participants will be stratified by baseline ferritin status and randomized to receive 100 mg lactoferrin + 5 mg iron, 300 mg lactoferrin + 5 mg iron, or placebo + 5 mg iron daily. Primary outcomes include changes in ferritin and hematological parameters. Secondary outcomes include VO₂peak, time to exhaustion, and blood lactate responses during standardized treadmill testing. This study will determine whether lactoferrin enhances iron homeostasis and improves physiological and performance outcomes in exercising women with low iron stores.

Dose-Response Impact of Geranylgeraniol (GG) Supplementation on Muscle Health

This study will evaluate the effects of daily geranylgeraniol (GG) supplementation on muscular strength, body composition, and aerobic capacity in healthy, physically active men and women. Approximately 60 participants aged 30-60 years will be enrolled in a randomized, double-blind, placebo-controlled, parallel-group trial lasting 8 weeks. Participants will be assigned to receive either placebo, 150 mg GG, or 300 mg GG daily. Outcome measures will be assessed at baseline, week 4, and week 8 and include maximal strength (1RM bench press and leg press), fat-free mass, muscular endurance, aerobic capacity (VO2peak), and circulating biomarkers related to metabolism and health.

Evaluating the Ability of a Multi-Strain Postbiotic to Impact Inflammation, Immune Components, Gastrointestinal Symptoms, Recovery, Anxiety, and Intestinal Permeability

This study will evaluate the effects of a multi-strain postbiotic supplement on markers of inflammation, immune function, gastrointestinal symptoms, psychological well-being, and intestinal permeability in healthy adults. The primary objective is to determine whether four weeks of postbiotic supplementation alters physiological and perceptual responses to a standardized bout of moderate-to-high intensity exercise compared with placebo. Approximately 50 healthy men and women aged 18 to 55 years will be enrolled in a randomized, double-blind, placebo-controlled, parallel-group clinical trial. Participants will be randomly assigned to receive either a multi-strain postbiotic supplement or a matched placebo for 28 days. At the end of the supplementation period, participants will complete a 45-minute treadmill exercise bout at 75% of their individually determined maximum heart rate. Blood samples will be collected to assess biomarkers of inflammation, immune activity, and recovery. Gastrointestinal symptoms, intestinal permeability, anxiety, and perceived recovery will be evaluated using validated questionnaires. This study is designed to determine whether postbiotic supplementation modulates physiological stress responses and subjective well-being following prolonged exercise in healthy adults.

Impact of Weizmannia (Bacillus) Coagulans JBI-YZ6.3 on Gut Health and Fecal Microbiome Changes

This study will evaluate the effects of supplementation with Weizmannia (Bacillus) coagulans JBI-YZ6.3 on gastrointestinal health in healthy, physically active adults. The primary objective is to determine whether daily intake of this probiotic strain improves symptoms of constipation and related gastrointestinal function compared with placebo. Approximately 30 healthy men and women aged 18 to 50 years will be enrolled in a randomized, double-blind, placebo-controlled, crossover trial. Participants will complete two 4-week supplementation periods, one with Weizmannia (Bacillus) coagulans JBI-YZ6.3 and one with placebo, separated by a 4-week washout period. The total duration of participation will be approximately 13 to 14 weeks, including screening and testing visits. Gastrointestinal symptoms will be assessed at baseline and after each supplementation period using validated questionnaires, with particular focus on the constipation domain of the Gastrointestinal Symptom Rating Scale (GSRS). Secondary outcomes will include additional gastrointestinal symptom domains and markers of perceived gut comfort and function. This study is designed to determine whether supplementation with Weizmannia (Bacillus) coagulans JBI-YZ6.3 produces clinically meaningful improvements in gastrointestinal symptoms in physically active adults compared with placebo.
