Recovery and Muscle Function After Supplementation With Turmeric

A Placebo Controlled, Randomised, Crossover Clinical Trial to Evaluate the Effect of Turmipure Gold® in Muscle Pain and Function Recovery in Moderately Active Adults

The objective of the study is to test the capacity of a five-day supplementation of Turmipure Gold® to improve exercise-induced muscle pain and function recovery in moderately active adults after exercise-induced muscle damage

Inclusion Criteria:

• Healthy free-living males

• Age: 25-45 years old

• Have a BMI between 18.5 and 28 kg/m²

• Moderately active with running 15-20 km per week

• With 1 to 4h of training per week, with maximum 1h of lower body heavy-load or resistance training (e.g., Hill running or hiking, HIT exercise, Squats, Lunges, Leg-press, Bench steps, etc.)

• Consent to the study protocol and to comply with study product

• Willing to limit caffeine, smoking, and alcohol consumption during the entire study period with no more than 5 cigarettes per day and 2 drinks. Also, alcohol consumption will not be allowed 24hours prior to exercise-induced muscular damage

• Willing to refrain from training for 3 days before the first test, 5 days before each damage-inducing exercise and during each supplementation phase, including active recovery exercises such as swimming, cycling at low intensity, unusual distance walking (however such should be encouraged during the 14 days wash-out)

• Willing to refrain the use of anti-inflammatory/pain reliever drugs such as paracetamol, NSAIDs, etc., during each supplementation phase, from 24 hours prior to 72 hours following the exercise-induced muscular damage

• Willing to refrain from 'recovery' treatments over the 72 hours following the damage inducing exercise such as:

  1. Hydrotherapy - cold water immersion, hot water immersion, or contrast therapy (as well as Jacuzzis, Steam baths, or Saunas)
  2. Massage - self, foam rolling, etc.
  3. Stretching
  4. Compression garments
  5. Topical applications - Tiger Balm, Deep Heat etc.

• Using omega-3-fatty acid, probiotic supplements, vitamins, minerals, or any dietary supplements (including botanicals), especially to maintain joint health 4 weeks prior to screening and during the entire study. Potential supplements include but are not limited to Beta-alanine, Creatine, HMB, Carnosine, Taurine, androstenedione, DHEA, Whey protein, or a pre-workout supplement

• Participants taking any anticoagulant or heparin treatment (including aspirin)
• Clinically significant abnormal laboratory results at screening

• History of non-compliance with medical treatments or recommendations.
• Participants who are required to perform squatting motions or descend a lot of stairs in their daily work activities, which may be painful following the Exercise Induced Muscle Damage.
