Your health is one of your most valuable assets, so it’s important to take extra precautions, as well as the steps needed to boost your health and immune system. Today and every day, we want our patients, staff, and community members to stay safe and healthy, that’s why this month’s blog will dive into the different vitamins and supplements that you can take to ensure a healthy and lively immune system

Primary Vitamins and Supplements

1) Vitamin C

Vitamin C plays an important role in supporting immune health, in which it is one of the key vitamins in protecting against viruses and infections. As vitamin C stimulates the formation of antibodies, along with the production, function, and movement of white blood cells, it helps reduce the occurrence of colds, fights colds more quickly, as well as ease any cold symptoms if taken prior to getting sick.  

Daily doses of vitamin C are typically between 250mg and 1000mg with the upper limit being 2,000mg. Food sources for vitamin C include citrus fruits such as oranges, grapefruit, and strawberries, along with sweet potato, peppers, kale, and broccoli.

2) Vitamin D

Vitamin D is a fat-soluble nutrient that is essential for the proper functioning of your body and immune system. It helps maintain optimal blood levels of calcium and phosphorus, as well as regulate antimicrobial proteins that can directly kill pathogens. Studies show that taking Vitamin D supplements also decreases inflammation and protects against respiratory tract infections.

Depending on your blood levels, Vitamin D supplements can be taken anywhere between 1000IU to 4000IU per day. However, vitamin D is best absorbed through sun exposure, in which 20 minutes of sunlight per day is ideal for the average person. Other sources of vitamin D include fatty fish such as salmon, egg yolks, and fortified dairy.

3) Zinc

Zinc is an important mineral that is required for proper body and immune system function. It is needed for bone growth, wound healing, eyesight, and brain development. Due to zinc’s ionophore activity which has antiviral effects against rhinoviruses, zinc also helps shorten the duration of common colds if taken within the first 24 hours of symptom onset. It reduces symptoms such as nasal congestion, nasal drainage, sore throats, and coughs.

The recommended daily amount of zinc is 8mg for women and 11 mg for men. As the upper limit for elemental zinc is 40mg, be cautious of the amount you are taking as excessive doses can cause zinc toxicity and have negative effects on your immune system. Food sources of zinc include red meat, poultry, fish, whole grains, milk, seeds, and nuts.

4) Vitamin B6

Vitamin B6 is essential for normal brain development, as well as for keeping the nervous system and immune system healthy. A healthy and varied diet should be sufficient in providing you with enough vitamin B6, in which food sources include poultry, fish, potatoes, chickpeas, bananas, and fortified cereals.

5) Iron

Iron is a mineral that is essential for the growth and development of your body. Your body uses iron to make proteins that carry oxygen from your lungs throughout your body and to your muscles. People who have low iron levels should take supplements to prevent iron deficiency.  The recommended dietary allowance which includes the iron you get from both the food you eat and the supplements you take is 8mg, with the upper limit being 45mg per day. Food sources of iron include shellfish, red meat, spinach, beans, and nuts.

  • Curcumin: Curcumin is the main active compound in turmeric, in which turmeric is used to lower inflammation, fight colds and flus, enhance heart health, manage weight, enhance brain function, support liver health, and improve digestion.
