How Much Vitamin C Should You Have Each Day

Vitamin C Can Act As A Pro

Can Vitamin C Cause Kidney Stones? How Much Vitamin C Per Day Should You Take?

What is a pro-oxidant? Its the opposite of an antioxidant. Instead of neutralizing reactive oxygen species it creates them by generating oxidative stress. This is a drawback that antioxidants can have to varying degrees, dependent on their concentration and the environment they are in.

In short, a pro-oxidant effect is the opposite of what you want!

Fully describing the Fenton and Haber-Weiss reactions will have to be a topic for another time!

In the case of vitamin C, the concerning reason it can act as a pro-oxidant is because it has been found to reduce metal ions through whats called the Fenton reaction. A symptom of overdose that you cant even detect!

Describing the Fenton reaction in full will make your eyes glaze. The important thing to know about is that its considered one of the most powerful methods of oxidation. This effect has been theorized to be a contributor to Parkinsons, Huntingtons, and Alzheimers diseases, among others.

Its inconclusive whether the thousands of different polyphenol antioxidants, which are non-vitamin micronutrients found in plants, also have the tendency to spur the Fenton reaction. Not to say they dont, but at least to date, theres not evidence to support that and research strongly suggests their antioxidant activity to be quite beneficial for your health.

What makes ascorbic acid unique is that it can recycle ferrous iron ions to continue to generate ROS, with more Fenton cycles. This is why vitamin C and iron is a bad combo.

Vitamin C And Immune Health

Vitamin C plays an important role in immune health and helps your body’s immune system in a few different ways. First, it supports the production of immune cells or white blood cells that you need to fight infections. Secondly, vitamin C functions as an antioxidant, which protects you from oxidative stress, which is linked to chronic health conditions and illnesses such as diabetes, heart disease and Alzheimer’s.

Tolerable Upper Intake Levels

The tolerable upper intake level is the maximum amount of a vitamin or mineral you can take without running the risk of experiencing unpleasant side effects.

Although it may be beneficial to take more than the recommended dietary allowance of certain vitamins, you should never take more than the tolerable upper intake level unless specifically instructed by a doctor to do so.

Some B vitamins, such as vitamin B12, thiamin, biotin, pantothenic acid and riboflavin, don’t have tolerable upper intake levels. This means that you’re unlikely to experience adverse reactions when taking these vitamins, even if you take high doses.

However, folate, vitamin B6 and niacin do have a tolerable upper intake levels. Getting more than 1,000 micrograms a day of folate, 35 milligrams a day of niacin or 100 milligrams a day of vitamin B6 may cause unpleasant side effects. Avoid taking a vitamin B complex supplement that contains more than these amounts.

Even though scoring all vitamins and minerals is essential for healthy living, not all of them are synthesized by our body in the same way. Hence, one must pay attention on how you have them.

While Vitamin C is a largely helpful nutrient, it is a water-soluble nutrient, which is best absorbed when you take them empty stomach. An ideal way would be to take your supplement first thing in the morning, 30-45 minutes before your meal. If you plan to take your Vitamin C later in the day, make sure there is a good gap after your meals so that it gets absorbed well.

Another way to match up on your requirement is to have a Vitamin -C rich diet, which you can have through the day.

What Are The Key Ingredients In Emergen C And What Do They Do For Your Immune System

Vitamin C is the number one ingredient in all the different versions of Emergen-C. You can think of it as the hero ingredient. The powdered products and chewables all have 1000 mg of vitamin C, while the gummies tend to have lesser amounts because there is only so much vitamin C that can be mixed into a gummy without making it taste gross. Vitamin C is by far the most well-known ingredient for immunity, going back many decades to the advocacy of the renowned chemist, Linus Pauling. For more background, you can check out these pages on the Linus Pauling Institute and the NIH Office of Dietary Supplements fact sheet.

Some people think that the effect of vitamin C on immunity has been debunked, but a number of clinical trials have proven that it works to help shorten respiratory tract infections. This is especially true in people under physical stress, like soldiers and marathon runners. The caveat is that you do need to take a significant amount every day to get the job done, at least 200 mg, and many studies have shown benefits with 500-1000 mg per day.

Emergen-C also has other ingredients that are important for the immune system. B vitamins like thiamin, riboflavin, niacin, B6, B12, and folate are all essential for immune cell production. It also has zinc, an essential mineral that plays a role in a huge number of physiological processes. Zinc is well known to support immune system health.
