Fish oil is derived from cold water fish... usually sardines, anchovies, mackerel or similar. Fish oil does a lot of good things: It's associated with lower mortality due to the benefits from long-chain n-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), fish oils contain omega-3 fatty acids, which play a role in animal lipid metabolism, and it's used by your body in cell membranes in your eye, brain and even in the reproductive system!
The fatty acids EPA and DHA are involved in regulating neuro- and inflammatory responses, metabolism and brain function. Most folks can't synthesize their own EPA and DHA in sufficient quantities, so hence supplementation.
Each bottle contains 40 doses.
Benefits of Fish Oil
Triglycerides: Doses of 0.85g/d and 3.4g/d were given to 26 otherwise healthy subjects with elevated triglyceride levels. The high dose lowered triglycerides by 27%, but lower dose had no significant effect.
Cholesterol: Meta analysis shows median dose of DHA 1.67 g/d resulted in a 0.23mmol/L increase for LDL and 0.07mmol/L in HDL. There's a variety of studies showing minor changes in cholesterol from fish oils.
Blood Pressure: Out of 90 randomized trials of fish oil and BP were identified from 1966 - March 2001, 36 trials were included in a metaregression analysis (the excluded studies were of poor quality, and included studies with interventions, no placebos etc). The median dose in trials was 3.7 g/day, and reduced systolic BP by 2.1 mmHg and diastolic BP by 1.6 mmHg. BP effects were more common in those that were >45 or were hypertensive.
Depression: Meta analysis indicates fish oil effective in reducing depression related to those diagnosed with bipolar. It seems to have little/no effect on mania. It might improve feeling of well being, however: In 33 otherwise healthy adults given 4g of fish oil (1,600mg EPA and 800mg DHA) for 35 days (dietary intake of fish at baseline not reported) noted that, alongside a somewhat normalized plasma ratio of omega 3:6 there was an improvement in overall mood state (more vigour with less aggression, fatigue, and depression). An increase in processing accuracy (reduced error frequency) and reduced reaction time were both noted.
Joint Health: Bunch of (presumably) older patients with arthritis were given the equivalent of 4.5g-9g of fish oil per day. There were significant improvements in both the number of tender joints and swelling (olive oil was also shown to have some benefit in this study).
In the second, and more relevant, study I'd like to include, a sub group of the studies 40 athletes were given 600mg of fish oil (376mg EPA, 264mg DHA). Subjective pain significantly decreased (i.e. athletes felt less acute stress), and increased 'sports activity' by 53% over baseline.
Ingredients & Function:
EPA, 1200mg per dose
DHA, 900mg per dose
Together, these fatty acids help lower triglycerides, blood pressure, cholesterol, and improve mood and joint health.
