A Study to Evaluate the Effect of Astaxanthin in Healthy Participants

Not Applicable

Completed

• Conditions: Healthy
• Interventions: Other: Placebo; Dietary Supplement: Astaxanthin

• Registration Number: NCT05376501
• Lead Sponsor: LycoRed Ltd.

Brief Summary

Astaxanthin is recognized as a bioactive compound with potential benefits for human health. This study aims to evaluate a specific nutritional supplement impact on markers of oxidative stress, inflammation, lipid levels, blood flow, visual skin markers, measures of longevity, mood and skin condition.

Detailed Description

A healthy diet is characterized by a high intake of various bioactive compounds usually found in natural, organic, and fresh foodstuffs. Among these bioactive compounds, astaxanthin, a red carotenoid pigment especially found in seafood, has been recognized in the scientific literature as a potential nutraceutical due to its antioxidant, anti-inflammatory, and neurotrophic properties. Previous studies have demonstrated reduced markers of oxidative stress and inflammation and improved blood rheology. Additionally, astaxanthin help maintain healthy skin.

This randomized, double-blind, placebo-controlled study will evaluate the impact of Astaxanthin supplemented for 12 weeks, on oxidative stress, inflammation, lipid levels, blood flow, skin hydration, visual skin markers, measures of longevity, mood states and facial skin satisfaction in healthy female adult participants.

2. Have a known allergy or hypersensitivity to astaxanthin or related carotenoids, including canthaxanthin, or have hypersensitivity to an astaxanthin source, such as Haematococcus pluvialis and known sensitivity, intolerability, or allergy to any of the study products or their excipients
3. Received a vaccine for COVID-19 in the 2 weeks prior to screening, current COVID-19 infections, or currently have the post COVID-19 condition as defined by World Health Organization (i.e., individuals with a history of probable or confirmed SARSCoV-2 infection, usually 3 months from the onset of COVID-19 with symptoms that last for at least 2 months and cannot be explained by an alternative diagnosis)
4. Major surgery in the past 3 months or individuals who have planned surgery during the course of the study
5. Participants with positive medical history of heart disease/cardiovascular disease, kidney disease, hepatic impairment or disease, or any other medical condition or diagnosis that the investigator would deem exclusionary
6. Participant with a positive medical history of unstable thyroid disease, immune disorder (i.e., HIV/AIDS), osteoporosis, a history of cancer (except localized skin cancer without metastases or in situ cervical cancer within 5 years prior to screening visit)
7. Participants with uncontrolled hematological, endocrine, cerebrovascular, cardiovascular, coronary, pulmonary, gastrointestinal, or neurological disease are excluded. Participants beginning a new medication or dose changed within the previous 3 months will also be excluded
8. Participants with diagnosed hypertension and/or diabetes

10. History of hospitalization or in-patient or out-patient treatment for alcohol or drug dependence or addiction within the 12 months prior to screening. Also, current problem of drug or alcohol abuse which, in the opinion of the investigator, might interfere with participation
11. History of hospitalization or in-patient treatment for depression or any related condition within the past five years. However, use of anti-anxiety/depressants is accepted as long as the dose has been consistent for a minimum of 3 months
12. Chronic or relapsing inflammatory and/or allergic skin conditions such as atopic dermatitis, rosacea, psoriasis and alike including telangiectasias ("spider veins")
