How Fish Oil Can Help you Lose Weight and Improve your Health


Fish oil is one of the most common supplements on the market. It’s rich in omega-3 fatty acids which play a role in reducing your risk of heart disease, brain disease, and can provide you with healthier looking skin. Fish oil has also been used to promote fat loss without the jittery and anxiety inducing effects of more traditional fat loss supplements.

Fish Oil Health Benefits

Large scale studies have shown that consuming fish oil supplements had a direct relationship with the reduction in the number of deaths from heart disease1. Additionally, research has shown that low intakes of omega-3 fatty acids, common in western diets, is correlated with cognitive decline in older adults, specifically Alzheimer’s2. Finally, studies have concluded that fish oil supplements can improve the elasticity and hydration of your skin3.

Fish Oil and Fat Loss

Taking fish oil supplements could help you lose a few extra pounds each month without any additional effort. It has been shown to enable fat loss, increase lean muscle mass, and minimize fat storage. One study showed that fish oil supplements reduced the overall body fat in adults by promoting fat oxidation without any additional changes in diet or exercise4. Another study concluded that taking fish oil supplements for a six week period resulted in an increase in lean muscle mass and a decrease in body fat5. Fish oil supplementation has also been shown to prevent fat accumulation and improve the metabolism of existing fat tissue6.

How Much Fish Oil Should you Take

If your not a fan of the taste of fish, the capsules keep the fish oil contained so you don’t have to taste it. Individuals have commented that they can be hard to swallow due to their size. Typically one 1,000mg pill will contain 300mg of active omega 3, with 3,000mg of fish oil a day being considered sage for adults to consume8.
