Title: LungVITamin D and OmegA-3 Trial
Brief Summary: The VITamin D and OmegA-3 TriaL (VITAL; NCT 01169259) is an ongoing randomized clinical trial in 25,871 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor® fish oil, 1 gram) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses.

This ancillary study is being conducted among participants in VITAL and will examine whether vitamin D or fish oil reduces respiratory morbidity, including COPD and asthma exacerbations, the risk of pneumonia, and airflow obstruction/decline of pulmonary function; and whether either of these interventions improves asthma control.


Options:
A: Postmenopausal women ages 50 to 79.
B: Inclusion Criteria:

* Both men and women
* Age \> 18 years
* Liver fat diagnosed on normal clinical grounds including in most cases liver assessed by Kleiner scoring system to classify severity, with no known aetiological factors for underlying liver disease (e.g. exclusion of hepatitis A, B \& C, primary biliary cirrhosis, autoimmune hepatitis, haemochromatosis). Last liver biopsy will be within 3 years of recruitment to the study.
* Liver fat diagnosed by ultrasound, CT or magnetic resonance imaging (MRI) in patients who also have either diabetes and/or features of the metabolic syndrome, without evidence of known aetiological factors for underlying liver disease (e.g. exclusion of hepatitis A, B \& C, primary biliary cirrhosis, autoimmune hepatitis, haemochromatosis).
* Alcohol consumption ≤ 14 units / week for women ≤ 21 units / week for men.

Exclusion Criteria:

* Alcohol consumption \> 15 units /week for women and \> 22 units /week for men.
* Decompensated acute or chronic liver disease.
* A history of viral hepatitis, diarrhoea, diverticulosis, irritable bowel syndrome, inflammatory bowel diseases, coeliac disease (seropositivity for anti-endomysial immunoglobulin A antibodies; immunoglobulin A (IgA) EMA).
* Previous bariatric or other abdominal surgery.
* Continuous use of antibiotics that may change gut microflora, probiotics, or antisecretory drugs capable of causing achlorhydria within the 2 months preceding enrolment, or evidence of immunoglobulin A or immunoglobulin deficiency (both of which produce confounding effects during assessments of intestinal permeability and small intestinal bacterial overgrowth).
C: * This study is open to all VITAL participants (NCT 01169259). Population includes men 50 years of age or older and women 55 years of age or older in the United States
* Participants who live in selected metropolitan areas of the U.S. (where we set up the infrastructure for clinic or home visits), are eligible for pulmonary function measurements.
D: Inclusion Criteria:

* women aged 35-60 years, men aged 45-60 years
* acceptance of the possibility to be given a placebo and acceptance of the constraints of participation
* lack of previous regular supplementation with any of the vitamins or minerals in the supplement provided
* absence of extreme beliefs or behavior regarding diet

Exclusion Criteria:

* disease likely to hinder active participation or threatened 5-year survival
