In order to be healthy and meet our various nutritional needs, we often turn to nutritional supplements. Some of us do this because it is almost impossible to get all the vitamins and minerals we need through our diet alone. Others do it because they want to enhance certain parts of their physique or need a little boost to help them loose weight or achieve fitness goals, for instance. So what are some of the most popular nutritional supplements on the market today and what do they do?

Green Tea

Green tea is so popular that there are now various nutritional supplements that add it as a main ingredient. Green tea is that popular because it is completely safe and is known to help with weight loss efforts.

“Research has shown that green tea contains compounds called catechins that may aid in weight loss. Specifically, a catechin called epigallocatechin gallate (EGCG), when combined with caffeine, was shown to elevate metabolism beyond that of caffeine alone.” – Nutrion Express

It is recommended to take 270mg per day of green tea to get the best effects. It helps with digestion, gives some energy (green tea does contain some caffeine), and has additional health benefits as well. Best of all, if you don’t want to take a capsule, you can simply drink a few cups of green tea each day.

American BioSciences ImmPower

This particular supplement is designed to boost the immune system.

“It’s one of the strongest immune supplements out there. Can be used year-round and/or during cold and flu season.” – Better Nutrition

Immune support is something we all need. We are so obsessed with hygiene that in protecting ourselves from the really harmful bacteria, we also stop ourselves from being exposed to the minor bugs that we could normally easily cope with. As such, when we do get into contact with cold and flu viruses in particular, we tend to get really ill, really quickly. Taking some supplements to help your immune system, particularly if you are struggling to eat a truly balanced meal, is always a good idea.

Fish Oil

Finally, there is fish oil or krill oil, which contains omega 3 fatty acids.

“These fatty acids have anti-inflammatory effect, proved to be beneficial to human health because help against cardiovascular disease and arthritis and even reduce the risk of cancer.” – Healthy Food House

One of the greatest things about fish oil and krill oil is that there are no reported negative effects. The only exception is in people who have a shellfish allergy, which obviously means they will have to avoid these types of supplements. The importance of omega 3 cannot be denied. As it is a fatty acid, this means that our body is not able to make it itself. We need both omega 3 and omega 6, but the food we consume is too high in omega 6. This means that we need to take products like fish oil in order to get the balance between the two right again. Considering how many illnesses it can prevent, it should be clear why everyone should take it.
