Vitamin C For Leaky Gut: Everything You Need To Know

Vitamin C is known to have many health benefits, but did you know it can also help with leaky gut? Living with this condition can significantly affect your quality of life, but fear not, as Vitamin C is a powerful ally that can help alleviate symptoms and support the body’s natural healing process. In this blog post, we will explore the connection between Vitamin C and leaky gut and how it can help improve symptoms. So, if you’re looking for more information about how Vitamin C can assist in managing leaky gut, read on!

What Is Leaky Gut?


Leaky gut, also known as increased intestinal permeability, is a condition in which the tight junctions of the intestinal walls become damaged or weakened. This damage leads to increased permeability of the intestinal wall, allowing bacteria, toxins, undigested food particles, and other waste products to pass through the gut wall into the bloodstream. This can cause a range of uncomfortable symptoms such as bloating, gas, fatigue, food sensitivities, joint pain, and skin problems (1). There are also studies that indicate that increased intestinal permeability is linked to many chronic diseases, including Irritable Bowel Disease (2), (3).

How Does Vitamin C Help?

Vitamin C has long been known for its role in immunity and overall health, but it can also play a crucial role in addressing leaky gut. Let’s explore how Vitamin C helps.

1. Fights inflammation and reduces oxidative stress: Vitamin C is renowned for its potent anti-inflammatory properties, which can effectively diminish gut inflammation. This is particularly significant in cases where leaky gut syndrome is present, as it can impede the healing process. Additionally, Vitamin C is known to reduce oxidative stress, further enhancing its therapeutic potential (4).

2. Boosts collagen production: Collagen is an important structural protein that helps to form the lining of the intestines. Vitamin C helps to stimulate the production of collagen, which can help to reduce the permeability of the intestinal lining, effectively minimizing the symptoms of leaky gut (5)

3. Shifts gut bacteria: A recently published study has highlighted the positive impact of Vitamin C supplementation on the gut’s bacterial composition. The study found that Vitamin C led to beneficial changes in the gut microbiota, ultimately promoting better gut health and improved overall gut function (6)

What Are The Best Sources Of Vitamin C?

Foods that contain Vitamin C
