Brief Summary

Vigorous exercise can stress the body. Consuming special types of diet supplements may help the body recover better from exercise. This includes a bright red supplement called astaxanthin that is found in certain algae and causes the pink-red color in salmon. Astaxanthin is an antioxidant and may protect cells from damage and improve the way the immune system functions. The main purpose of this study is to determine if 4 weeks of consuming astaxanthin improves recovery from 2.25 hours of intensive running on a treadmill. This study will also measure whether or not astaxanthin supplementation improves skin health

Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Male or female, ages 18-57 years.
  • Non-smoker.
  • Capable of running 2.25 h on laboratory treadmills at 70% VO2max (close to marathon race pace).
  • Agree to train normally, maintain weight, and avoid the regular use of large-dose vitamin and mineral supplements, herbs, and medications that influence inflammation and immune function (especially Advil, Motrin, aspirin, and similar anti-inflammatory drugs) for the duration of the 10-week study. (Review supplement and medication use with the Research Manager during orientation).
  • Agree to taper exercise training prior to each of the two lab running sessions (as if preparing for a race).
  • Willing to avoid astaxanthin supplements (other than what is provided) and natural sources of astaxanthin including algae, yeast, salmon, trout, krill, shrimp and crayfish during the 10-week study.
  • Categorized as "low risk" using the American College of Sports Medicine screening questionnaire.
  • Generally healthy and without chronic disease including cardiovascular disease (e.g., heart disease, stroke), cancer, type 1 and 2 diabetes, rheumatoid arthritis.

You may not qualify if:

  • Inability to comply with study requirements.
  • Body weight below 110 pounds.
  • Pregnant or breastfeeding.
  • Any other concurrent condition which, in the opinion of the primary investigator (PI), would preclude participation in this study or interfere with compliance.
  • Current diagnosis of cardiovascular disease, diabetes, or cancer (except for non-melanoma skin cancer).
  • History of allergic reactions to astaxanthin.
  • Using drugs with 5-alpha-reductase inhibitor (Proscar, Propecia, Avodart, Jalyn).
