Gut health has become a major trending topic in the health industry, especially with the discovery of the gut-brain axis. This connection allows the gut and brain to communicate and influence each other. For example, mental stress can slow digestion and affect the microbiome. When gut function is disrupted, it can reduce serotonin production, potentially lowering mood. With all the buzz around gut health, most people are aware that probiotics are beneficial. Today, however, we’re focusing on supplements that support gut health, even though it’s not their primary purpose. Keep reading to discover how Astaxanthin, Turmeric, Collagen, Omega-3, and Anxiety Relief may contribute to better gut health.

1. astaxanthin

What is astaxanthin and what is it known for?

Astaxanthin is a reddish pigment found in certain algae and fish. It acts as a potent antioxidant and has been shown to reduce the risk of various health issues. People often take astaxanthin to improve eye health, boost physical performance and recovery, strengthen the immune system, and support skin health. But that’s not all—research has revealed even more benefits. Astaxanthin has been linked to lower triglyceride levels, improved blood flow, enhanced cognitive function, reduced inflammation, and even protection against DNA damage (1, 2, 3).

How does astaxanthin affect gut health?

Astaxanthin has been observed to positively influence the gut microbiota (the balance of bacteria in your digestive system), particularly in individuals with fatty liver disease. Specifically, it decreased 5 different types of bad bacteria and increased 2 different types of beneficial bacterial (4). One of the beneficial bacteria that astaxanthin increased has been linked to better barrier function in the gut (5). Additionally, a different study found that supplementation with astaxanthin decreased the presence of helicobacter pylori bacteria in cases of H. pylori infection.

It is also worth mentioning that astaxanthin’s powerful antioxidant capacity may reduce inflammation in the gut (6). This in turn may have a positive effect for individuals with chronic upset stomachs and constipation. There was a study published in 2008 that examined the effects of astaxanthin on menopausal women with high oxidative stress levels and it was found that their constipation was reduced (7).

2. TUrmeric

What is turmeric and what is it known for?

Turmeric is that bright yellow spice you often see in curry dishes, but it’s much more than a flavorful ingredient. It comes from the root of the Curcuma longa plant and has been a staple in traditional medicine for centuries. The secret to turmeric’s power? Curcumin, its active compound, which gives it incredible anti-inflammatory and antioxidant properties. Turmeric has become popular for managing joint pain, arthritis, and various inflammatory conditions. It’s also known to support liver health, improve skin, and give your immune system a boost.

How does turmeric affect gut health?

It turns out that turmeric isn’t just good for your joints and immune system—it can also do wonders for your gut. Research shows that turmeric extract (curcumin) promotes the growth of beneficial bacteria like Bifidobacterium and Lactobacillus—the same types of bacteria found in probiotics. At the same time, it helps reduce harmful bacteria like Prevotella, Bacteroidaceae, and Rikenellaceae, which are often linked to disease. (8)

Additionally, Curcumin can strengthen the intestinal barrier, a protective layer that keeps harmful substances from entering the bloodstream. By keeping this barrier intact, turmeric can help maintain a healthy gut and improve overall digestion. (8)

3. Collagen

What is collagen and what is it known for?

Collagen is the most abundant protein in the human body and a key component of connective tissues, such as skin, tendons, ligaments, and bones. It plays a critical role in maintaining skin elasticity, joint health, and muscle strength. As we age, collagen production naturally declines, which can contribute to wrinkles, joint discomfort, and weaker bones. Collagen supplements are often used to support skin hydration, reduce the appearance of fine lines, and improve joint flexibility. In addition, collagen is frequently used by athletes for recovery and to maintain strong joints and muscles during intense physical activity.

How does collagen affect gut health?

In a study of healthy adult women, eight weeks of supplementation with 20mg of collagen per day split into 2 dosages seemed to reduce bloating and improve mild digestive symptoms (9). Collagen also seems to act as a prebiotic, meaning that it nourishes the good bacteria in the gut (10). Having a healthy intestinal flora can help to reduce inflammation and support healthy digestion. It’s important to remember that while the connection between collagen and gut health is not extensively studied, its benefits for skin and joint health are well studied and show consistent results.

4. Omega-3

What is omega-3 and what is it known for?

Omega-3 refers to a group of essential fatty acids that play a vital role in various bodily functions. It plays a role in heart health, brain function, and reducing inflammation throughout the body. Omega-3s are most commonly found in fatty fish like salmon, mackerel, and sardines, but can also be sourced from plant-based foods like flaxseeds and walnuts. Regular omega-3 intake has been linked to a lower risk of heart disease, improved cognitive function, better joint health, and reduced symptoms of conditions like arthritis (11). Omega-3 is widely recognized for its anti-inflammatory properties and its ability to support both cardiovascular and mental health.

How does omega-3 affect gut health?

Omega-3 fatty acids can have a positive effect on gut health by promoting a healthy balance of bacteria in the microbiome. Studies suggest that omega-3s increase the levels of beneficial bacteria, such as butyrate-producing strains, which are known for their anti-inflammatory properties. At the same time, omega-3s can help reduce harmful bacteria often linked to inflammatory gut conditions like IBD. (12)

Additionally, omega-3s may improve the integrity of the intestinal barrier, helping to protect the gut lining from damage and reduce inflammation. This protective effect may contribute to better digestion and overall gut function, especially in individuals with chronic inflammatory conditions. (13)

5. Anxiety Relief

What is Research Verified Anxiety Relief and what is it known for?

Research Verified Anxiety Relief is a dietary supplement designed to help reduce symptoms of anxiety. It is known for its blend of natural ingredients that are believed to support mental health and promote a sense of calm. All of the ingredients in Research Verified Anxiety Relief are backed by clinical studies and the product itself has garnered many positive reviews over the years.

How does Anxiety Relief affect gut health?

Chronic stress can lead to elevated cortisol levels, which negatively impact the immune system and gut health. Initially, this may cause mild symptoms like gas, but it can progress to more significant issues like abdominal pain. Additionally, poor dietary choices during stressful periods can exacerbate these issues by causing an imbalance in the gut microbiome (14). Furthermore, stress is linked to irritable bowel syndrome (IBS), characterized by discomfort and constipation (15). While probiotics can be helpful for getting your gut back on track, it’s necessary to also address the root of the problem. For this reason, Research Verified Anxiety Relief may help to prevent a deterioration in gut health by reducing anxiety.
