Can You Take Probiotics With Hashimotos?

In this guide, I am going to analyze the potential relationship between probiotics and Hashimoto's disease by exploring the role of gut bacteria in thyroid function.

Keep reading to find out if you can take probiotics for Hashimotos or not and to find out what probiotic supplement real people on Reddit recommended.

What Is Hashimoto Disease?


Hashimoto's disease, also known as Hashimoto's thyroiditis, is an autoimmune disorder that affects the thyroid gland and can cause a variety of symptoms, including fatigue, weight gain, and cold intolerance but does vary from person to person.

The thyroid gland is a small butterfly-shaped gland located in the neck that produces hormones that regulate metabolism and other body functions. In Hashimoto's disease, the immune system attacks and destroys the thyroid gland, leading to an underactive thyroid gland (hypothyroidism).

Hashimoto's disease is the most common cause of hypothyroidism in the United States. It is typically treated with hormone replacement therapy to restore normal thyroid function but some studies seem to suggest a link between the microbiome and thyroid health.

What Are Probiotics?

Probiotics are live microorganisms best described as good bacteria because of how they can assist with gut health but if you already have a healthy gut, it's unlikely probiotics will help with anything.

Today, many different probiotic strains are available in supplement form but can also be found in certain foods, such as yogurt, kefir, and kimchi that can also be eaten by people with Hashimoto's.

Dr. Sara Mesilhy told me that "A healthy gut has beneficial effects on thyroid function, which may be obtained from certain probiotics. However further studies needed to evaluate the exact impact of dysbiosis on thyroid function and diseases such as Hashimoto."

Gut Bacteria May Influence Thyroid Function

The gut microbiota has a strong impact on the activity of the immune system and thyroid function. There is a higher prevalence of coexisting thyroid and gut-related diseases, such as Hashimoto's thyroiditis/Graves' disease and celiac disease/non-celiac wheat sensitivity.

Dysbiosis, an alteration in the gut microbiota, is a common finding in thyroid disorders. It can alter the immune response by promoting inflammation and reducing immune tolerance, which can damage the intestinal membrane and increase intestinal permeability (Leaky Gut). This exposes the body to more antigens and leads to local inflammation.

Dysbiosis can also directly impact thyroid hormone levels through its own deiodinase activity and the inhibition of thyroid-stimulating hormone (TSH). The composition of the gut microbiota also influences the availability of essential micronutrients for the thyroid gland, including iodine, selenium, zinc, and iron.

Probiotics have been shown to have beneficial effects in thyroid diseases and can improve trace element levels and prevent thyroid hormone fluctuations. Future well-powered studies are needed to evaluate the impact of gut microbiota on thyroid function and diseases.

Probiotics For Hashimoto's Reddit Analysis

3 years ago in the official Hashimotos subreddit, a Redditor started a thread asking if anyone with Hashimotos took a probiotic and had noticed a positive difference. The replies were mostly positive with Bacillus Spore Forming based bacteria seemingly being the best probiotic strain for Hashimotos based on my analysis.

Rebajeansy reported that taking Meg's sporebiotic from microbiome labs helped their antibodies drop from 1,027 to 115 within a year. RoughRollingStoner replied mentioning that their naturopath recommended Mega Sporebiotic and they noticed an improvement in their energy levels just days after starting it.

Meat_Mithkabob, mentioned that using prebiotic fiber from the Bulletproof brand had been amazing for them, improving their bowel movements and assisting with their seizures. Someone else however reported that their doctor suggested probiotics, but they did not notice any effects from taking them.

Closing Thoughts: No Studies Prove Probiotics Can Help With Hashimoto's

In conclusion, the probiotics & gut microbiota may play a role in the development and progression of autoimmune thyroid disorders such as Hashimoto's disease.

Probiotics may have beneficial effects on thyroid function and can improve trace element levels and prevent thyroid hormone fluctuations, so yes, you can take probiotics with Hashimotos but they are not a treatment or cure.

However, more research is needed to fully understand the impact of gut microbiota on thyroid function and diseases. There are no clinical studies that show probiotics can help with Hashimoto's disease.

It is always important to consult with a healthcare provider before taking probiotics, particularly if you have a compromised immune system or other underlying health conditions. I am not a doctor.
