Brief Summary

The present randomized, double-blind, placebo-controlled crossover trial aims to evaluate the effects of Relora supplementation on responses to induced stress produced by a combination of cognitive and physiologic stressors in healthy men and women. The effects of the supplement, compared with a placebo, will be evaluated using measures to assess anxiety \[State-Trait Anxiety Inventory-Part 1 (STAI-Part 1), mood \[Bond-Lader Visual Analog Scale (VAS)\], hypothalamic-pituitary-adrenal axis activation (salivary cortisol) and cognitive function (cognitive flexibility, reaction time, processing speed, attention, sustained attention, working memory, and executive function). Testing will be completed at the beginning and end of 7-d supplementation periods with the active and placebo products to assess both the acute effects and the "acute-on-chronic" effects following one week of daily use.

Outcome Measures

Primary Outcomes (1)

  Day 7

Secondary Outcomes (3)

• Total area under the curve (AUC) for salivary cortisol from 90 to 150 min and 180 to 240 min at the end (day 7) of each of the two treatment conditions

  Day 7

• Bond-Lader post-dose VAS scores (collected as part of the test battery at the t = 90 and 180 min timepoints) at the end (day 7) of each of the two treatment conditions.

  Day 7

• Cognitive function post-dose test scores (collected as part of the test battery at the t = 90 and 180 min timepoints) at the end (day 7) of each of the two treatment conditions.

  Day 7

Other Outcomes (6)

• STAI-Part 1 mean and individual timepoint post-dose scores (collected as part of the test battery at the t = 90 and 180 min timepoints) at the start (day 1) of each of the two treatment conditions.

  Day 1

• Total area under the curve (AUC) for salivary cortisol from 90 to 150 min and 180 to 240 min at the start (day 1) of each of the two treatment conditions.

  Day 1

• Bond-Lader post-dose VAS scores (collected as part of the test battery at the t = 90 and 180 min timepoints) at the start (day 1) of each of the two treatment conditions.

• Subject is willing and able to attend the screening visit and 4 test visits lasting up to \~4 h each (visits 2 through 5; days 1 and 7 of Period I and Period II, respectively).
• Subject is able to maintain immersion of non-dominant hand, including the forearm, into ice water (0-4°C) for ≥30 seconds during the CPT at visit 1 (day -6).
• Subject is willing to refrain from alcohol for 12 h prior to each test visit (visits 2 through 5; days 1 and 7 of Periods I and II, respectively) and to limit alcohol consumption to no more than one serving of alcohol (1 drink = 12 oz beer, 5 oz wine, or 1.5 oz hard liquor) the 24 h prior to each test visit (visits 2, 3, 4, and 5; days 1 and 7 of Period I and Period II, respectively).
• Subject is willing to limit caffeine-containing beverages/foods/products consumed at the breakfast meal on all test visit days (visits 2, 3, 4, and 5; days 1 and 7 of Period I and Period II, respectively) to no more than 1 serving (150 mg) ≥2 h prior to each test visit.
• Subject is willing to consume a hearty breakfast on a daily basis throughout the study period with replication of the timing and quantities of food and beverages consumed at the visit 2 (day 1) breakfast meal on the morning of each subsequent test visit (visits 3 through 5; day 7 of Period I and days 1 and 7 of Period II).
• Subject is willing to replicate the timing and dose of any necessary morning medications and/or supplements taken prior to coming to clinic on visit 2 (day 1) at each subsequent test visit (visits 3 through 5; day 7 of Period I and days 1 and 7 of Period II).
