As daylight hours decrease during the fall and winter, so do your vitamin D stores, affecting your immune system. This nutrient is crucial for supporting the immune system and preventing colds and flu so it’s important to consume it as much as we can.
Salmon contains Astaxanthin, which is produced by countless microalgae and phytoplankton in the sea. Astaxanthin helps in cardiovascular health, immune system, and eye health. Astaxanthin is more powerful than Vitamin E, Vitamin C, and many others in supporting the immune system. It also helps in maintaining the integrity of all cell membranes including those of your immune cells.
