Benefits of Taking Vitamin C and Zinc Together
There are several potential benefits to taking Vitamin C and Zinc together as they work together to support immune health. Here are the benefits of each individually.†
Benefits of Vitamin C
Vitamin C is a water-soluble vitamin that primarily acts as an antioxidant. As an antioxidant, Vitamin C functions as an antioxidant helping support the immune system from neutralizing free radicals in the body. This helps your immune system stay healthy and powerful. †
Benefits of Zinc
Zinc is anessential mineral that not only is beneficial for our immune function but for many other functions in the body. It is needed for many important functions including immune support and healthy growth and development, and supports the vital functions of over 100 different enzymes in the body which is important for overall health.†
In the immune system, Zinc is needed for the proper function of T-cells and B-cells, which are also types of white blood cells. Additionally, it supports other immune cells such as neutrophils and natural killer cells. Essentially, it is an important essential mineral for your immune health. †
Other Ways to Support Your Immune System
Beyond taking Vitamin C and Zinc together, there are many ways that you can naturally support your immune system.
Getting adequate sleep supports our circadian rhythms and nightly repair of our bodies, to increase its protection against potential pathogens, and also may help long-term adaptive immunity. Guidelines state that adults ages 18 or older should get at least 7 hours of sleep each night.
Stress is known to disrupt the function of your bodily systems, including the immune system.. Help manage your stress through calming activities, developing healthy coping mechanisms, speaking with trusted individuals in your life, regular exercise, and good nutrition.
Nutrient shortfalls can negatively affect the immune response due to the body not having adequate building blocks for proper immune function. Eating a varied diet that includes fruits, vegetables, healthy proteins, whole grains, and dairy or dairy alternatives provides your body with the nutrients that are important for normal immune function.
Regular exercise supports the movement of nutrients and white blood cells throughout the body and can help support a normal inflammatory response. For healthy adults, the Physical Activity Guidelines for Americans recommend 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity aerobic exercise per week, with additional muscle-building and balance-supporting exercises.

Current guidelines state that the Recommended Dietary Allowance of Vitamin C for adults is 75 mg for non-pregnant women and 90 mg for men.

In certain situations, such as during pregnancy and lactation, Vitamin C requirements increase, and individuals who smoke require an additional 35 mg/day when compared to nonsmokers. 
For healthy adults, the Tolerable Upper Level Intake (UL) for Vitamin C is 2,000 mg per day. Doses above the Upper Limit for vitamin C are not suggested since it may cause undesirable side effects.. 
The RDA for Zinc is 11 mg daily for adult men 18 years or older, and 8 mg daily for adult women over the age of 19. Zinc needs increase for pregnancy and lactation and may be affected by certain medical conditions.
