Our immune system helps sustain our overall health and wellbeing. While there are several ways to help ensure a well-functioning immune system, making sure that we provide our bodies with nutrients that support our healthy immune system is also really important. Read on to discover which nutrients provide immune system support, each nutrient’s role in your immune system, and the foods and/or immune supplements that deliver these nutrients.†
Vitamin A is a fat-soluble vitamin that includes active Vitamin A (or retinol) as well as carotenoids, which are precursors that are converted to active Vitamin A in the body. Beta-carotene is the most common of these carotenoids. Vitamin A has been recognized for its importance in the immune system.1 Vitamin A also helps support cellular processes in the immune system.2 Good food sources of Vitamin A and its precursor, beta-carotene, include:
Dark green leafy vegetables
Deep orange fruits and vegetables
National survey data shows that 45% of Americans are not consuming enough Vitamin A from their diet alone.3 A supplement containing Vitamin A (such as Nature Made® Vitamin A liquid softgels) may help fill a nutrient gap from inadequare dietary intake.
Many Americans are not consuming enough Vitamin C through their diet alone (about 37%),3 making it a common nutrient gap in the US. If you do not consume the fruits and vegetables above, consider a Vitamin C supplements, such as Nature Made® Vitamin C with Rose Hips to help meet your daily Vitamin C nutrient needs.†
This essential fat-soluble vitamin, studied primarily for its role in bone health, has also been studied extensively for its importance in immune system health.† Vitamin D receptors are located in almost all immune system cells, where Vitamin D regulates and enhances the immune response and is involved in immune cell function.5, †
Vitamin D is found in only a few foods, including fatty fish, cod liver oil, egg yolks, and vitamin-D fortified milk. Sunlight is also a source of Vitamin D, however many people do not meet the minimum requirement of sun exposure (without sunscreen) of 5-30 minutes a day/two times a week.6 Some people have a higher risk of Vitamin D deficiency, including those with darker skin pigmentation, the elderly, obese individuals, and those living in areas with limited sunlight.7 Consequently, national surveys show that 95% of Americans are not consuming enough Vitamin D from their diet alone,3 and approximately 1/3 of the US population, including children, adolescents, adults, and the elderly, are suffering from either insufficient or deficient levels of Vitamin D.8 Your doctor can perform a simple blood test to determine your Vitamin D status. A Vitamin D supplement is an inexpensive, safe and effective way to help ensure you are receiving adequate amounts of this important nutrient. Try Nature Made® Vitamin D3 Adult Gummies.
When choosing immune system support supplements, consider vitamin E to help support immune cell function. Vitamin E is a fat soluble essential nutrient that has antioxidant properties to help ward off damage from oxidation in the body. Vitamin E may help neutralize damaging free radicals and help protect healthy cells.† Good food sources of Vitamin E include:†
Zinc is an essential part of hundreds of different processes throughout the body, including the immune system, which is why it is a key nutrient for immune system health.† The immune system relies on zinc for normal development and function of immune cells.10 Zinc is also required for certain antioxidant enzymes and helps to protect cells from susceptibility to oxidative damage.11 Zinc can be found in shellfish such as oysters and crab, as well as some animal sources like beef, pork and turkey. If you do not regularly consume these foods, consider taking a zinc supplement for immune support, like Nature Made® Super C Immune Complex with Zinc Tablets.†
