Winter brings low temperatures, which in turn can mean that you are susceptible to viruses and illness. Krill oil supplements were proven to boost your immune system.
Running or cycling through the winter is recommended to maintain the fitness levels that you’ve worked hard to build up during the summer, but this also means that road grime can easily end up in your body after a long wet weekend ride.
Usually your body can combat these infections, but its protective properties can be weakened at times if the body has been put under stress or if certain nutrient or vitamin stores are limited.
Experts from the University of Glasgow discovered that the group taking krill oil supplementation for six weeks saw significant increases in the production of IL-2 (a signalling molecule that manages immune cell activity) and NK (Natural Killer) cells, which play a crucial role in fighting off viruses and bacteria. Despite not showing any direct link to running or cycling performance, having a strong immune system leads to benefits in your performance in the long term.
Krill oil was also proven to relieve joint stiffness, improve brain function, cardiovascular health and eye health.
In addition to krill oil supplementation, there are other ways to increase your immune system function such as certain foods, including garlic, carrots and strawberries.
