7 Best Gut Supplements

A healthy gut biome is essential to overall health – for optimal digestion, a healthy immune system, and even for mental health.1 Maintaining a healthy gut biome in today’s busy world can be challenging, so this article will present the 7 best gut supplements to keep you healthy.

 

What is the Gut?  

When people use the term “gut”, they are generally referring to more than just our stomach, but the whole digestive system, which begins at the mouth and ends at the anus. The digestion of food begins as we chew and each step in the process of digestion (esophogus, stomach, small intestine, large intestine) plays a different role in breaking down our food into the nutrients that we can absorb.  

A healthy digestive system is also home to many beneficial bacteria that assist with nutrient absorption and our overall health.2 A healthy gut supports:

  • Optimal digestion1
  • Our immune system to keep us from getting sick3
  • Better mental health1
  • Reduced levels of inflammation2
  • Healthy bones3

A healthy gut can also be linked to performance!

7 Best Gut Supplements 

There are several types of supplements that you can use to support your gut health. 

 

Probiotics: “good bacteria” in simple terms, probiotics (and their precursor form ‘prebiotics’) support the growth and maintenance of healthy bacteria in our gut. They can help with daily digestion and support the overall health of the gut.4

 

L-glutamine: this amino acid has many benefits, but one of which is supporting gut health. L-glutamine can help balance the bacteria in your gut, regulate inflammation, and support a healthy gut mucosal wall.5

 

Psyllium husk: psyllium husk is a common ingredient in fiber supplements that our body cannot digest; however, this source of fiber has been found to help regulate bacteria levels in the gut and support regular digestion.6

 

Fish oil supplements: there is research supporting how polyunsaturated fatty acids like omega 3s in fish oil support optimal gut microbiome health.7

 

Phytonutrients: the unique nutrients that we get from plants like fruits and vegetables have been shown to have important roles in gut health even beyond the benefits of fiber. Taking a greens supplement can help provide a dose of the plant powered phytonutrients to help support your gut and overall health. 7

 

Ginger: ginger is a powerful food that has been used for centuries in many cultures, and has recently been found to play a role in the regulation of bacteria levels in the gut. While more research is needed, it looks like ginger also plays a role in gut health.8

 

Artichokes: packed with fiber, artichokes are a nutrient dense plant that has also been linked in early studies with supporting healthy bacteria levels in the gut. While more research is needed, artichoke derived supplements seem promising to support gut health.9

 

 

Take Home Message

While good digestion is important, gut health means so much more than just absorption of our food. Supporting your gut with supplements like probiotics, fish oil, and psyllium can help maximize the levels of healthy bacteria in your gut and improve your mental health, immune system, and bones at the same time.
