Conditions
Brief summary
Investigate the in vivo effects of n-3 PUFA supplementation on inflammation, gene expression and epigenetic signatures. Ex vivo stimulation of peripheral blood mononuclear cells (PBMCs) collected pre and post n-3 supplementation and measurement of it's effect on inflammation, gene expression and epigenetic signatures.
Interventions
28 days of a commercially available supplement. 4 capsules per day.

Eligibility
Inclusion criteria
* Healthy males * Aged between 18 and 30 years
Exclusion criteria
* Females (Due to differences in cell membrane incorporation of n-3 PUFAs between the sexes and the testing schedule being unable to fit in with menstrual cycle, therefore altering the blood markers that are being measured). * Aged below 18 or above 30. * Body mass index (BMI; in kg/ m2), below 18 or above 30. * Use of vitamin or fish oil supplements in the last 6 months. * High habitual oily fish consumption (\<4 servings per month). * Smoking. * Changes in weight in the past 6 months (Dieting) or planning on changing dietary habits. * Habitual use of anti-inflammatory drugs. * Self-reported history of diabetes. * History of heart disease, coagulation/bleeding disorders, metabolic disease or Serious allergy. * Known to have blood-borne virus. * Receipt of inoculations within 2 months of starting the study or the intention to receive such during the study. * Donation of or intention to donate blood within 8 weeks of the first sample or at any point during the intervention.
