Do High Doses of Protein Supplements Affect Serum Lipid Profiles?

Completed

• Conditions: To Study the Effects of Protein Supplements on Blood Tests

• Registration Number: NCT04170036
• Lead Sponsor: Near East University, Turkey

Brief Summary

Protein supplements are widely used among people going to the gym. The effects of these substances on blood biochemical, hematological, inflammatuary, glucose metabolism markers and lipid profile is not well known. The previous studies on this issue give inconclusive results. So the investigators aimed to investigate this subject and compare the blood tests between subjects using and not using protein supplements.

Detailed Description

As more people are doing regular exercises, people using protein supplements are also increasing. The effects of these substances on blood lipid profiles, biochemical, hematological parameters, inflammatory and glucose metabolism markers are not well known. So the investigators of this study planned to search the effects of these substances on blood tests. Totally 69 subjects going to the gym for at least three preceding months were included to the study. They were divided into two groups: the ones using protein supplements and the ones who never used these substances. Demographic and clinical characteristics were recorded. Dietician assessed the dietary habits of the subjects. Blood was drawn for the tests mentioned above from all of the subjects. And the results were compared between the two groups.
