Probiotics as a Supplement to Antidepressants: Benefits and Risks

Probiotics as a Supplement to Antidepressants: Benefits and Risks

Depression is real—you wake up each morning with a heavy heart and a constant sense of weariness. Even with the support of therapy and medication, the path to recovery can feel endless. The frustration of not feeling better, despite following your treatment plans diligently, is a common pain point for those battling depression.

Could there be an additional ally in this journey? Probiotics, those beneficial bacteria known for supporting gut health, are emerging as a potential companion in the fight against depression. But can you take probiotics while on antidepressants? Let’s explore the benefits and risks of combining them and transform your treatment experience with renewed hope and energy!

Understanding antidepressants

Mental health disorders are more common than you might think, affecting millions worldwide. Did you know that one in seven Indians suffer from mental disorders? Most of them rely on antidepressants to manage this condition. But what are these medications? Before discovering whether you can take probiotics and antidepressants together, let’s see how antidepressants work!

Antidepressants are specialised medications that are prescribed by doctors to help alleviate symptoms of depression, anxiety, and various other mental health issues. Their magic lies in their ability to modulate brain chemicals—specifically neurotransmitters like serotonin, norepinephrine, and dopamine—which play a crucial role in regulating mood.

However, their use is not as straightforward as popping a pill when you're feeling down. These medications are powerful and complex, necessitating careful prescription and supervision by a healthcare professional. Some of the most common types of antidepressants include: 

  • Selective Serotonin Reuptake Inhibitors (SSRIs): These antidepressants work by increasing serotonin levels in the brain, which can improve mood and reduce anxiety.
  • Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): This antidepressant boosts both serotonin and norepinephrine levels, offering another avenue for managing depression and anxiety.
  • Tricyclic Antidepressants (TCAs): They affect a broader range of neurotransmitters but are typically used when other medications haven't been effective.

It's important to note that antidepressants are not a quick fix. They often take a few weeks to reveal their full effects, requiring patience and ongoing adjustments under medical supervision. You might even experience side effects, ranging from mild nuisances like nausea and headaches to more concerning issues like sexual dysfunction.

So, with a reminder that these medications are not a DIY solution to mental health woes, let’s get down to deciphering the connection between your gut and brain!

The gut-mental health connection

Have you ever noticed how your mood changes when you’re having a bad stomach? Besides suffering from the pain, it seems even the tiniest things irk you. This connection between your gut and brain is stronger than you might think. It’s called the gut-brain axis, and it highlights the intricate relationship between your digestive system and mental health.

In this relationship, the gut acts as a second brain, teeming with trillions of bacteria, fungi, and viruses known as the gut microbiota. They do more than just digest food. They produce and interact with neurotransmitters, influencing everything from your mood to your sleep cycle. For example, serotonin, which is often dubbed the happy hormone, is primarily produced in your gut, not your brain.

However, when your gut balance is disrupted, all these functions go into disarray. Studies suggest that people suffering from depression often have different gut microbial profiles compared to those without depression. It’s also found that gastrointestinal disorders like IBS and ulcerative colitis are often associated with elevated rates of depression and anxiety, further cementing the gut's role in your mental health journey.

Here’s where probiotics—live beneficial bacteria found in foods like yoghurt and kimchi—come into play. By restoring balance to your gut microbiome, they support a healthy gut and inadvertently help manage symptoms of depression and anxiety. 

But are you already taking antidepressants? If so, is it wise to take probiotics along with them? Let’s find out!

Benefits of taking probiotics while on antidepressants

Going for therapy and taking antidepressants seem to be the only ways to cope with depression. But if you’re looking for more than symptom management and wish to address the root cause, probiotics might be the most simple and effective solution out there. However, most of you are concerned about taking probiotics with antidepressants. Can you combine their intake?

The short answer is yes, you can. Combining probiotics with antidepressants may offer additional benefits for mental health:

  • Alleviating depressive and anxiety symptoms: A study demonstrated that participants using both probiotics and antidepressants experienced a more significant reduction in depressive symptoms compared to those who only took antidepressants. This is because probiotics introduce beneficial bacteria in your gut and help in the production of neurotransmitters, which help regulate your mood.
  • Improving emotional processing and brain activity normalisation: Studies have shown that probiotics can help regulate brain activity associated with emotional processing. It was found that taking probiotics for just four weeks can lead to improvements in mood and emotional regulation, an effect not observed in those who did not take probiotics. 
  • Enhancing the efficacy of antidepressants: Probiotics may enhance the effectiveness of antidepressants by improving their absorption in the gut, leading to higher blood levels and better treatment outcomes. Probiotics may also help reduce the side effects of antidepressants, such as digestive issues and weight gain.

So, you’ve seen one side of combining probiotics with antidepressants. Let’s flip the coin and look at the complexities that might arise due to their combined intake!

Potential risks of combining probiotics with antidepressants

Imagine starting your day with a probiotic smoothie, hoping it will complement your prescribed antidepressants to tackle depression holistically. Initially, you feel fine, but over the next few weeks, you notice unusual changes—uncomfortable bloating, bouts of indigestion, and inexplicable shifts in mood. Though you can take probiotics while on antidepressants, you must approach it with caution. Here are some potential risks to keep in mind: 

  • Changing nature of gut flora: One significant risk of combining probiotics with antidepressants is the alteration of gut flora, which can lead to gut dysbiosis. While probiotics are typically considered beneficial, their excessive or inappropriate use can disrupt the delicate balance of bacteria in the gut. This can result in digestive discomfort and even lead to mood swings and anxiety. 
  • Interactions with antidepressants: Probiotics may interact with certain medications, including antidepressants. Even though the interaction is not fully understood, it can lead to reduced medication effectiveness or the emergence of new side effects. 
  • Individual variability: The effectiveness of the combined intake of probiotics and antidepressants can vary from person to person. Given that each person's gut microbiome is unique, this can lead to significantly different responses when combining treatments. So, what works for one person might be detrimental to another.

So, the time has come for you to experiment with taking probiotics and antidepressants together. While there are potential mental health benefits of their combined intake, you must integrate them with care. 

To minimise risks, it's essential to consult a healthcare professional before starting to use probiotics with antidepressants. They can provide personalised treatment plans and closely monitor for any adverse effects.
