There are several commercial supplements out there, and Emergen-C is one of them. It is a nutritional supplement made primarily with vitamin C alongside other beneficial nutrients.

Emergen-C is made to help increase your body’s defense mechanism and boost energy levels. To take Emergen-C, you need to mix the powder with water to make a beverage with a strong orange-like scent. Many people use this supplement as a prophylactic treatment against cold and flu, especially during their seasons. While it can protect against respiratory tract infections, some people wonder if it can be any effective. This article discusses everything you need to about Emergen-C and the health benefits of vitamin C.

What Is Emergen-C?

Emergen-C is a nutritional supplement loaded with vitamin B and vitamin C. It is claimed to be highly effective at improving your immune system and increasing energy levels. It is available in powdered form in packets for a single serving. The powder is to be mixed with 118-177 ml of water. Its manufacturers say that the resulting liquid contains more vitamins than ten oranges. The original formulation of Emergen-C contains 35 calories, 6 g of sugar, 1000 mg of vitamin C (equivalent to 1667% of the recommended daily intake/RDI), 10 mg of vitamin B6 (equivalent to 500% of the RDI), 25% of the RDI for vitamin B1 (thiamin), and 25 mcg of vitamin B12 (equivalent to 417% of the RDI). Additionally, the supplement contains decent amounts of vitamin B2 (riboflavin), vitamin B9 (folic acid), vitamin B5 (pantothenic acid), vitamin B3 (niacin), and magnesium. The supplement is available in 12 varied flavors.

How It Prevents Cold and Flu

Many people use Emergen-C to protect themselves from the attacks of cold. This is because the supplement provides nutrients that interact directly with your immune system. Please have a look at the major nutrients in it and its mode of action.

Vitamin C

For every single serving of Emergen-C, there is up to 1,000 mg of vitamin C. This is far beyond the recommended daily value of 90 mg and 75 mg for men and women, respectively. Studies on the dosage of vitamin C have not clearly shown whether a higher or lower dose of it can reduce the severity and duration of the cold. One study indicates that supplementing with 200 mg of vitamin C per day can lower the risk of flu by three percent and its duration by eight percent. However, for people with high levels of physical activity, such as soldiers, vitamin C can reduce the risk of flu by up to 50%.

B Vitamins

One serving of Emergen-C contains several B vitamins, including folic acid, niacin, pantothenic acid, thiamin, riboflavin, vitamin B12, and vitamin B6. Your body needs all these vitamins to help convert food into energy. For that reason, the B vitamins are sometimes referred to as energy-boosting nutrients. According to the National Institutes of Health, B vitamins deficiency usually presents with profound lethargy. Correcting this deficiency is marked with improved energy levels.

Nevertheless, it is unknown whether those who have enough B vitamins can benefit from supplementing with them. It is worth noting that deficiency of some B vitamins like vitamin B6 and B12 can lower your immune response. Evidence suggests that taking supplements of vitamin B6 or vitamin B12 (50 mg or 500 mcg respectively) every day for 14 days can significantly improve your immunity.


Some researchers claim that supplementing with zinc can reduce the duration and severity of cold by up to 30%. This is true because zinc is involved in the maturation and function of immune cells. That said, Emergen-C doesn’t contain enough zinc that can produce these effects. The proven clinical studies achieved their results by using about 75 mg of zinc. Remember, the amount of zinc in a single serving of Emergen-C is only 2 mg. You can get a higher amount of this mineral from Immune Plus, which is a variety of Energen-C. However, this will only provide 10 mg of zinc, which is still not enough.

Vitamin D

Research has shown that many immune cells have vitamin D receptors, meaning that vitamin D has unidentified roles in immunity. Taking supplements of vitamin D at a dosage of 400 IU for every other day can lower your likelihood of developing cold and flu by up to 19%. This has been shown to be more beneficial for those who have a deficiency of vitamin D. For vitamin D provision, you can go for another variety of Emergen-C, Immune Plus, which contains 1,000 IU of this vitamin in just a single serving.

Other Ways You Can Improve Your Immunity

Support Your Gut Health

Improving and maintaining your digestive health have combo benefits. There are millions of good gut bacteria in your gut that work tirelessly to maintain healthy immunity. To increase their growth and health, you can eat a diet rich in fiber because these bacteria feed on fiber to produce butyrate and other compounds keeping your gut healthy. You may consume probiotics in fermented foods like yogurt, kefir, and kimchi. Cut back on your intake of artificial sweeteners because they impair blood sugar control and encourage the growth of bad gut bacteria.

Engage in Regular Exercise

Studies suggest that regular exercise improves your immunity and lowers the chances of falling sick. Experts advise that you need to exercise for at least 150 minutes every week.

Sleep Adequately

Getting enough sleep goes a long way to improving your immunity. Try to sleep for 7-9 hours every night. This can reduce the risk of infections like cold and flu.


Emergen-C is a nutritional supplement that comes in 12 different flavors. It is in the form of powder which is mixed with water and taken to boost the immune system and increase energy levels. It primarily contains vitamin C and several B vitamins. It works better to prevent and reduce the severity of cold and flu.
