Sometimes it's hard to get enough of all the immune system supporting nutrients you need from your diet alone. Drinking an oral nutrition shake like Ensure or Glucerna is a convenient way to help supplement your diet. Look for shakes that contain the key nutrients protein, vitamin A, antioxidants, zinc and vitamin D.

Ensure nutritional shakes support immune health by supplying protein, vitamins A and D, zinc, and vitamins C and E. These shakes are kosher, halal, and suitable for lactose intolerance. * * Not for people with galactosemia.

ENSURE PLUS provides concentrated calories and protein to help patients gain or maintain healthy weight. It can benefit patients who have malnutrition, are at nutritional risk, or are experiencing involuntary weight loss. For oral use. For interim sole-source nutrition.

A high-fiber plant-rich diet with plenty of fruits, vegetables, whole grains, and legumes appear to support the growth and maintenance of beneficial microbes. Certain helpful microbes break down fibers into short chain fatty acids, which have been shown to stimulate immune cell activity.

Boosts Your Immune System Proteins are made of amino acids. These compounds help turn key players in your immune system -- T cells, B cells, and antibodies -- into germ fighters that spot and kill harmful cells that enter your body before they can start an infection.

Safety and precautions. Both Ensure and Boost shakes may cause side effects, such as constipation, nausea, and flatulence. However, user reports indicate that most of them go away when consumed consistently. Other reported side effects include muscle cramps, irregular heartbeat, and shortness of breath.

The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with.

But for your body to perform them optimally, you need to be getting enough protein. The authors of the first study cited in this article noted that the amino acids arginine, glutamine, and cysteine are particularly important for regulating immune function.

Proteins might also be involved in playing solely protective roles against infections like various cell surface receptor proteins (Toll-like receptors, Nod-like receptors, etc.), which trigger protective immune responses.

Both Ensure and Boost shakes may cause side effects, such as constipation, nausea, and flatulence. However, user reports indicate that most of them go away when consumed consistently. Other reported side effects include muscle cramps, irregular heartbeat, and shortness of breath.
