If the first measurement is slightly elevated above these limits, the subject will be given a brief (5 minute) rest period, and two more measurements will be taken. The average of all three measurements will be used to determine eligibility.
- Normal supine, resting heart rate (\<90 per minute).
- Able to provide an adequate blood draw.
- Habitually consumes ≤ 240 mg caffeine/day (equivalent of 3 cups of coffee). Dietary supplementation consistent over one month and able to maintain supplementation throughout study.
- If dietary supplement initiated within the past month, participant is willing to discontinue supplement use followed by a 2-week washout prior to participation in the study.
- Willing to duplicate their previous 24-hour diet, refrain from caffeine for 12 hours, refrain from exercise for 24 hours prior to each trial, and fast for 8 hours prior each of the treatments.
You may not qualify if:

- Other known gastrointestinal or metabolic diseases that might impact nutrient absorption or metabolism, e.g. electrolyte abnormalities, diabetes, thyroid disease, adrenal disease, hypogonadism, short bowel syndrome, diarrheal illnesses, history of colon resection, gastric ulcer, reflux disease, gastroparesis, Inborn-Errors-of-Metabolism (such as PKU).
- Chronic inflammatory condition or disease (e.g. rheumatoid arthritis, Crohn's disease, ulcerative colitis, Lupus, HIV/AIDS, etc.).
- History of hepatorenal, musculoskeletal, autoimmune, or neurologic disease.
- History of cognitive disorder.
- History of psychiatric disorder.
- Known sensitivity to any ingredient in the test formulations as listed in the Certificates-of-Analysis.
