Brief Summary
The goal of this 16-week double-blind, placebo-controlled pilot study is to determine whether daily Diaplex supplementation improves insulin sensitivity and glycemic control in adults with elevated blood glucose levels, while generating high-quality preliminary data on metabolic effects, glycemic patterns, and safety to inform future trials

Eligibility Criteria
You may qualify if:
- BMI 18.5-29.9 kg/m² (normal to overweight)
- Generally healthy individuals with no metabolic or endocrine disorders besides elevated blood glucose levels, meaning no metabolic syndrome, insulin resistance diagnosis, dyslipidemia diagnosis requiring treatment, thyroid disorders, etc.
- Stable weight for the past 3 months (±5%)
- Sedentary or lightly active baseline lifestyle (Light activity ≤3 times/week (e.g., walking, yoga, casual biking)
- Willingness to maintain usual diet, activity, and sleep patterns for 16 weeks
- Able and willing to wear a CGM for the final 10-14 days
- Willing to complete 3-day dietary recalls, sleep and activity logs
- Not taking or willing to stop taking supplements containing chromium, vitamin A, vitamin B6, iodine, and niacin
You may not qualify if:
- Any diagnosed metabolic/endocrine disorder, other than elevated blood glucose levels, such as metabolic syndrome, insulin resistance diagnosis, clinically significant dyslipidemia, thyroid dysfunction or use of thyroid medication, or obesity-related endocrine dysfunction
- Medications and supplements use of glucose-lowering medications within the past 3 months, including use of weight-loss drugs or metabolic agents, such asGLP-1 RAs (Ozempic, Wegovy, Rybelsus, Trulicity, Victoza, Saxenda) or GIP/GLP-1 RAas (Mounjaro, Zepbound)
- Use of supplements within the last 30 days containing chromium, vitamin A, vitamin B6, niacin, iodine
- Unwilling to discontinue prohibited supplements
- Health Conditions \& safety such as elevated ALT/AST more than 2× the upper limit or known chronic liver disease or diagnosed renal impairment (eGFR \<45 mL/min/1.73 m²), uncontrolled hypertension (\>160/100 mmHg)
- Pregnant, breastfeeding, or planning pregnancy
- Allergy or sensitivity to study ingredients or CGM adhesives
- Lifestyle and compliance (\>30 minutes/day of intense physical activity (active adults or athletes))
- Participation in another investigational trial in the past 30 days
- Any condition that may interfere with participation or data quality (per investigator guidance)
