In conclusion , Zinc supplementation  has favourable effects on plasma lipid parameters .
Zinc supplementation  significantly reduced total cholesterol , LDL cholesterol and triglycerides .
Therefore it may have the potential to reduce the incidence of atherosclerosis related morbidity and mortality
Zinc is a mineral that plays a vital role in many biological processes and plays an important role in insulin action and carbohydrate metabolism .
It may also have a protective role in the prevention of atherogenesis .
Numerous studies have evaluated the effects of Zinc supplementation on serum lipids in humans and have demonstrated varying results .
We systematic ally evaluated the literature and performed a meta- analysis on the effects of Zinc supplementation on serum lipids .
Nutritional and haematological status of Chinese farmers: the influence of 13.5 months treatment with riboflavin, retinol and zinc.
A retinol ( 15 mg ) , riboflavin ( 200 mg ) and zinc ( 50 mg ) supplement or a placebo ( D-mannitol ) was given to 610 Chinese farmers weekly for 13.5 months .  Riboflavin , retinol , beta-carotene , tocopherol and zinc status were measured in all subjects at the start and end of the intervention and in a sub sample at 2 months . Plasma vitamin C , haemoglobin and haematocrits were measured on other sub sample s at the end of the supplementation period . At the start vitamin A , zinc and riboflavin status were poor . Plasma retinol and zinc concentrations were higher in men than women but the opposite was observed with respect to beta-carotene . There was no difference between the sexes for tocopherol and riboflavin . Tocopherol : cholesterol ratios suggested vitamin E status was good and vitamin C status also appeared adequate . The supplement increased plasma retinol throughout the whole period but riboflavin status improved only over the first 2 months and then remained constant . Plasma zinc increased in both treatment and placebo groups by approximately 15 to 20 per cent in men and women . Mean concentrations of retinol and tocopherol and beta-carotene ( in women only ) increased by approximately 20 per cent in the placebo group . It is argued that seasonal factors and /or the placebo may have been responsible for the increase in retinol and beta-carotene in the placebo group . The lack of an increase in beta-carotene in the men may have been due to their higher retinol requirements . Lastly , the increase in retinol may have been responsible for the increase in tocopherol and zinc in plasma since these nutrients increased in those whose plasma retinol increased , irrespective of treatment
