If you are not getting adequate amounts of oily fish in your diet on a regular basis you are more than likely not getting enough Omega-3 Fatty Acids with sufficient amounts of EPA and DHA.

Why does this matter?

Sufficient amounts of high quality Omega-3 Fatty Acids on a daily basis can improve:

Joint Inflammation
Heart & Cardiovascular Health
Brain Function
Overall Inflammatory Response

Most of our customers prioritize their Full Mega on a daily basis for some of the benefits they feel on a daily basis like less joint pain and less brain fog.

Full Mega is one of those supplements that often gets skipped over because it is simple and not as flashy as a new pre-workout but it is what we refer to as a needle mover because it has been a game changer for some of our customer’s overall health and how they feel in and outside of the gym.
