Does Emergen-C Work? Here's What Doctors Think Ahead Of Cold + Flu Season

What's the difference between cold and allergy symptoms?

Having seasonal allergies can be confusing when they coincide with cold season. Between kids being back in school and the weather changing, the fall/winter seasons seem to bring on sneezing, coughing, and more. But, how can you tell when you're merely dealing with allergies or something else?

"Colds are viral infections. Symptoms include a sore throat, cough and feeling tired," says Dr. Purdy. Dr. Stanford further explains that viral infections have "traditionally been Rhinovirus species, but it may also be Adenovirus species and others." Colds can also be accompanied by a fever in some cases.

On the other hand, Dr. Purdy and Dr. Stanford both agree allergies are specifically caused by allergens or irritants. "Common Symptoms include sneezing and itchy eyes," says Dr. Purdy. According to the CDC, around one quarter of adults deal with seasonal allergies (raises both hands), so it's not weird if you get confused about when it's time to switch from Claritin to Dayquil.

How should people relieve cold symptoms before heading to the pharmacy?

Before you head to CVS at the first sign of sneezing and a sore throat, there are a few things Dr. Stanford suggests you do. "Optimizing our immune systems by focusing on overall health and wellbeing can help reduce the risk of infections, including the common cold. This includes eating a healthy diet, being physically active, getting enough sleep, and keeping stress in check," she says.

Unfortunately, Gallupreports that 57% of people feel they're not getting the proper amount of sleep they need. But, this doesn't mean you should ignore your lack of rest just because others are struggling too. Take it from someone whose insomnia impacted their mental health and a nasty bout of the Flu followed by Covid-19 two years ago! "Properly treating other health conditions can also help prevent acute illnesses, like the common cold," says Dr. Stanford.

However, it's not unusual to get a cold because Dr. Stanford says they're the "result of germs spread from contact with others." Taking precautions just helps your immune system work the eliminate the viral infection faster.

Do elderberry and Vitamin C fight off colds?

This is where things get a little tricky. Though elderberry and Vitamin C have been hailed as supplements that combat colds, not everyone agrees on their effectiveness. Dr. Stanford says, "While the evidence for Vitamin C in treating colds is mixed, sufficient research suggests that taking vitamin C supplementation can shorten the duration and reduce the severity of cold symptoms." But if you're thinking about relying on Vitamin C supplements, Dr. Stanford is less likely to encourage you to take them because they haven't been proven "to be effective in preventing common cold symptoms."

She also doesn't think you should take elderberry as if that'll also fight off a viral infection. "Elderberry is not effective in preventing colds, and evidence is insufficient to suggest that it is effective in treating the common cold," she explains.

Do you recommend relying on Emergen-C to help combat cold symptoms?

So, what's the verdict on taking Emergen-C once it's confirmed you have a viral cold? The brand has several products that range from gummies to drink mixes, all aimed at supporting your immune system — but does that mean they're safe to take? According to Dr. Purdy, they are! "Emergen-C contains Vitamin C which is great for a good and healthy immune system and recovery. It also contains other good for you ingredients that help with your immune system like vitamin E and Zinc."

However, it's valid to want to know if there's a difference between Zicam and Emergen-C. According to Dr. Stanford, there is! "Similar to Vitamin C, evidence suggests that zinc may be effective in reducing the duration and severity of cold symptoms, but it is less likely to be effective in preventing the common cold," she explains. Plainly put, think of the two like this:

• Zicam = Zinc
• Emergen-C = Vitamin C

She even says, "Studies suggest taking both zinc and vitamin C could be beneficial!"

Can certain teas help soothe sore throats associated with colds?

Drinking warm tea can help alleviate cold symptoms, though you shouldn't think they're your only defense against viral infections. In conjunction with cold medicines, "throat coat teas really help soothe inflammation and help manage symptoms," says Dr. Purdy. The reason for this is that most "throat support products are indicated to ameliorate sore throat and similar symptoms, often by numbing agents, temperature, and other factors," Dr. Stanford explains. In short, don't be afraid to use tea as a form of hydration while you're sick!

Dr. Purdy says other things you can use to help alleviate your symptoms are a humidifier, nasal spray, and drops. Take it a step further by taking a "steam shower" to "provide some much needed relief."
