Benefits of Omega-3 

Weight Loss

For anyone fighting their weight or wanting to maintain their weight, fish oil can help adults either maintain a healthy weight or aid in weight loss. Being obese can increase the likelihood of developing diabetes, cancer, and heart disease. Fish oil can help you maintain your body and reduce the risks of developing problems in obese adults.

Losing weight happens at a greater rate when consuming fish oil capsules when you are dieting and exercising. Even if the weight does not slide off like you hope it will, the waist-to-hip ratio and waist circumference can reduce their size.

Vision Improvement

Your weight is not the only thing that improves when you consume fish oil. Your eyesight may see an improvement. As you age, your vision does start to decline, and your risk of developing an eye disease increases. Studies conducted on people who consume fish oil have shown that taking it for at least four months can improve your vision.

Reduce Disease and Inflammation

Consuming fish oil can help reduce the fat in your liver. You do not need to ingest large amounts of alcohol to get liver disease. Inflammation can spread throughout your body with unhealthy living, stress, and poor diet, and consuming fish oil can help your liver functioning improve.

Reduce Mental Disorders

Depression and anxiety are common mental illnesses; both men and women can develop. While consuming omega-3 fish oil will not stop the development of depression or anxiety, it does help lower blood levels and improve any symptoms of depression. Fish oil that has high EPA levels reduces the number of depressive symptoms that can develop.

Improve Cognition

Your memories and general cognition can improve with the consumption of fish oil regularly. Consuming fish oil can reduce the development of Alzheimer’s disease. Alzheimer’s disease accounts for a decrease in mental agility and functioning of aging adults. Alzheimer’s disease is increasing in the United States, and consuming fish oil can reduce its development.

Benefits of Omega-3 for Men

For men, the benefits are many. Studies have shown that the consumption of fish oil can help reduce the chances of prostate cancer. Reducing inflammation throughout the male body is possible when a man consumes omega-3 through fish or fish oil supplements.

Heart disease is a leading killer of men, and consuming omega-3 fatty acids can help improve heart health while lowering triglycerides. Omega-3 fatty acids are important for maintaining cardiovascular health and preventing other types of diseases.

Benefits of Omega-3 for Women

For women, consuming larger amounts of fish oil can make the development of a growing fetus. The benefits continue after the child is born through breast milk. The fetus and future infant can see faster development of coordination and hand-eye movements if their mothers consume fish oil supplements. There are also studies, which indicate improved vision and a reduced risk of allergies in children.

Outside of having children, ingesting fish oil can help women’s hair and nails grow and improve in strength. The fish can also help with giving a woman healthy skin, especially as a woman ages.

Bone health can also improve with the consumption of fish oil. Osteoarthritis and osteoporosis develop for many women as they age. Fish oil contains high levels of omega-3, which in turn contains high levels of vitamin D and calcium, which are crucial for female bone health.

The omega-3 fish oil supplements help to improve the mineral density within a woman’s bones. Improved mineral density ensures strong bones and less of a chance for breaking brittle bones or developing conditions that would make them brittle.

How Much Omega-3 should you take?

Finding the right kind of fish oil can make a difference in its effectiveness. Consuming at least one to two portions of fish a week can help improve your overall health. When it comes to taking fish oil throughout your week, you should adjust your dosage to your age and health. The World Health Organization recommends up to 500 mg daily with more recommended for pregnant or nursing mothers.

You should research the type and form of fish oil supplement, with triglycerides, triglycerides, and ethyl esters being common ways to consume and absorb the fish oil. High levels of EPA and DHA should be at least 500 mg, as it will indicate the degree of effectiveness when consumed. To ensure the freshness of the product you buy, you should keep the supplement away from light, preferably in the refrigerator. Fish oil can go bad, and a supplement that has vitamin E added will help keep the freshness of your fish oil for the long-term.

Omega 3 Fish Oil and Bodybuilding

Although omega 3 fish oil doesn’t quite directly contribute to and support muscle growth like protein supplements do, it can’t be denied that it plays a key role in the growth and development of muscle in bodybuilders of all shapes and sizes.

Omega 3 fish oil supplements are considered some of the healthiest and most beneficial supplements on the planet.

They provide numerous general health and well-being benefits, including being able to protect the brain and heart. From a bodybuilding standpoint, however, fish oils are ideal for the following reasons:

1. Fish Oil Helps Burn Fat

Let’s face it, none of us want to be fat at the best of times, and body fat and bodybuilding just do not go together.

The idea behind bodybuilding is to lose fat whilst building muscle, which is why omega 3 fish oil supplements are ideal.

Although these are fats, these are healthy fats and when consumed, they aren’t actually stored as body fat in the body at all.

Instead, they’re used as energy which increases the metabolism and therefore helps us to burn even more calories stored in our body fat.

2. It Helps Promote Muscle Growth

Another reason why fish oil is considered beneficial for bodybuilding is the fact that it helps to reduce the catabolic (muscle wasting) hormones such as cortisol, making it an anabolic (muscle building) supplement.

Fish oil also helps increase protein synthesis, which in turn aids in post-workout muscle recovery when new muscle proteins are synthesized by the body.

3. It Reduces Inflammation

Bodybuilding is a very physical sport, and it’s probably safe to say it’s pretty painful at times as well.

Bodybuilders will often feel sore and their muscles will ache following a workout, because they have literally destroyed their muscle tissue.

This places stress on the body and can cause painful swelling and inflammation, which hinders protein synthesis and muscle growth.

Fish oil is a potent anti-inflammatory which means it can play a key role in post-workout muscle recovery and repair.

4. Omega 3 Fish Oils Promote Healthy joints

Another key bodybuilding benefit of fish oils and fish oil supplements is the fact that they promote healthy joints and help to lubricate them, preventing inflammation and helping to ward of conditions such as arthritis.

Bodybuilders’ joints take a real pounding as they build muscle because they become so much heavier.

The knees in particular are the first to suffer which is just another reason why fish oils are so beneficial.

5. Omega 3 Fish Oils Help Increase Energy Levels

Bodybuilding is a very tiring sport, both physically and mentally, and if you think that your energy levels are only affected whilst working out, you’ve obviously never really tried your hand at real bodybuilding.

Of course the workouts themselves are physically demanding as the idea is to push your body to its absolute limits whilst in the gym, to help shock it into new muscle growth and recovery.

Each workout should be more effective than your last, which will mean more weights, more reps, less recovery, more volume, and the more energy required as a result.

The great thing about omega 3 fish oil supplements is that they have been proven to substantially increase the amount of energy produced by the body.

The two main reasons for this are that as these fatty acids are a form of fat, the body is able to utilize them immediately.

Contrary to popular belief, carbohydrates are not the body’s preferred source of energy, fats are, and so by increasing the amount we consume, we increase the amount of energy produced as a result.

They also help to increase the metabolism, which also brings us to our next benefit.

6. They Help To Promote Fat Loss

It may seem a little bizarre to some of you – eating fat to lose fat, but remember that omega 3 fish oils are healthy fats, and so they behave differently once consumed.

Numerous studies have confirmed that omega 3 fatty acids could play a key role in weight management and fat loss, for many different reasons.

The first reason is that although they are fat, they’re structurally different than unhealthy fats, which means that once consumed, the body immediately uses them as a source of energy, before it has a chance to break them down and store them as body fat.

They also help to increase the metabolism, which means that we burn more calories, and also have more energy.

This increase in energy is especially beneficial because the more energy we have, the more effective our workouts become and so the more body fat we can lose as a result.

7. They Improve Brain Health and Function

When it comes to bodybuilding, the brain is one of the most important parts of our body we could ever imagine.

A key element of bodybuilding, weight training, and exercise in general is what is known as the “mind – muscle connection”.

This is basically the art of actually visualising which muscles are being worked with each exercise, visualising the benefits, and of course, actually helping you to focus and get in “the zone” so that when you are training, your mind is firmly fixed on your training, rather than what you plan on watching on TV when you get home.

Studies have found that omega 3 fish oils are incredibly healthy for the brain, particularly because they help increase serotonin levels.

This helps improve mental focus and clarity, it helps prevent Alzheimer’s and dementia, it boosts memory and reaction speeds, and much more besides.
