Antioxidant Effect of Ozonated Vegetable Oil and Vitamins in Moderately Active Subjects
- Conditions
- InflammationOxidative Stress
- Interventions
- Dietary Supplement: Ozonized vegetable oil with vitamines
- Registration Number
- NCT05592509
- Lead Sponsor
- S&R Farmaceutici spa
- Brief Summary
The purpose of this pilot study is to evaluate the antioxidant effect of a nutraceutical formulation based on vegetable oil and vitamin complex (vitamin K2 and vitamin B9) in subjects with the same level of physical activity (LAF 1.70-1.99, normally active or moderately active).
- Detailed Description
Study design: The pilot study will enroll 20 subjects with physical activity level LAF 1.70-1.99 (normally active or moderately active).
The 20 subjects will be divided into two groups of 10 subjects following randomization. The first group will take the dietary supplement (three capsules per day) for 60 days, while the second group will take a placebo (three capsules per day) for 60 days.
During the treatment period (60 days), the two groups will undergo follow-ups at days 0, 15, 30 and 60 within which clinical and hematochemical examinations will be conducted. At the end of the 60 days, after the wash-out period (two weeks), as per the cross-over design the group previously taking the dietary supplement will be on placebo (three capsules per day) for 60 days, while the group previously taking placebo will take the dietary supplement (three capsules per day) for 60 days. Again, follow-ups will be at 0, 15, 30 and 60 days.

- Primary Outcome Measures
Name Time Method Evaluation of hematic oxidative stress by quantifying biological antioxidant potential (umol/l) evaluation after 60 days of treatment after crossover Evaluation of the ability of the dietary supplement to modulate oxidative stress over time by quantifying biological antioxidant potential using umol/l as units of measure comparing with the placebo-treated group at each follow-up
Evaluation of hematic oxidative stress by biological antioxidant potential (umol/l) evaluation after 15 days of treatment before crossover Evaluation of the ability of the dietary supplement to modulate oxidative stress over time by quantifying biological antioxidant potential using umol/l as units of measure comparing with the placebo-treated group at each follow-up
Evaluation of hematic oxidative stress by quantifying ROS (CARR U) evaluation after 60 days of treatment after crossover Evaluation of the ability of the dietary supplement to modulate oxidative stress over time by quantifying reactive oxygen metabolites (ROS) using CARR U as units of measure comparing with the placebo-treated group at each follow-up
