Reishi Mushrooms During Pregnancy: Are They Safe? (Risks, Tips, & More)

Many mothers-to-be are understandably cautious about what they consume during this significant phase. One common query that arises is whether reishi mushrooms, known for their myriad health benefits, are safe to enjoy during pregnancy. 

After all, they promise some of the best benefits for women, from stress reduction to enhanced sleep and many more things an expecting mother may need.

So, what's the verdict? Is it safe to take reishi mushrooms during pregnancy? And if so, what benefits can you expect? Let's dive right in:

• Reishi mushrooms have a historical reputation for health benefits but lack extensive research on safety during pregnancy.
• Potential benefits include immune support and stress reduction, but risks such as effects on blood clotting warrant caution.
• Expectant mothers should consult healthcare providers, consume reishi in moderation, and be mindful of any adverse reactions.

Reishi mushrooms, scientifically known as Ganoderma lucidum, have earned a long-standing reputation in traditional medicine, particularly in Asian cultures. 

Often referred to as the "mushroom of immortality," these fungi have been cherished for centuries for their potential health-boosting properties, ability to improve sleep, and benefits for hair and skin. 

Reishi mushrooms, with their potential benefits, naturally catch the attention of those seeking a wholesome diet or supplemental routine during this critical period. For instance, a mother may choose reishi mushroom coffee during pregnancy as a substitute to regular coffee beverages. 

In general, reishi is thought to be beneficial for:

• Immune Support: Reishi mushrooms may boost the immune system, helping the body defend against infections and illnesses.
• Stress Reduction: Known for adaptogenic properties, reishi could help the body cope with stress and anxiety, promoting relaxation.
• Anti-Inflammatory Properties: Reishi mushrooms is one of many mushrooms with anti-inflammatory properties that help reduce inflammation in the body, potentially aiding various health conditions.
• Improved Sleep: Some individuals claim that reishi can support better sleep and relaxation, contributing to overall well-being. 
• Potential Anticancer Effects: There's ongoing research suggesting that reishi mushrooms may have properties that inhibit the growth of cancer cells, though more research is needed for conclusive evidence.
• Heart Health: Reishi may contribute to heart health by lowering blood pressure and cholesterol levels.

It's important to note that while these benefits are supported by some research and traditional use, further studies are required for a complete understanding of the extent and effectiveness of reishi mushroom's potential health benefits.

We'll dive into the specific potential benefits of Reishi down below, but for now let's address the question that brought you here–is it safe to consume reishi during pregnancy? Take a peek below:

Limited research exists on the specific effects of reishi mushrooms on pregnant individuals. However, according to Health Canada’s mushroom recommendations, Reishi and Shiitake are the only medicinal mushrooms that do not require warning labels for pregnant or breastfeeding mothers. In other words, Reishi has not been proven unsafe. 

The U.S. FDA does not require such a label either. That means that you may be fine to take reishi during your pregnancy, assuming you have a healthy, normal pregnancy and work closely with your healthcare professional to monitor reishi's effects.

Still, there are some general reishi risks you should be aware of, as well as some steps you can take to avoid them. But first, let’s look at some of the reasons you may be considering reishi during pregnancy:

Although we covered some of reishi's general benefits earlier, we want to take a deeper dive into the purported benefits of Reishi mushrooms for expecting mothers. 

After all, when it comes to reishi mushrooms during pregnancy, it's about weighing the potential benefits against the risks. Then you can make an informed choice that aligns with your well-being and that of your growing child.

Reishi is rich in two constituents, β-D-glucans (mushroom polysaccharides), known for their immunomodulatory properties, and triterpenoids, which exhibit potent antiviral properties. 

These compounds interact with the body in a variety of ways, but perhaps their most notable interaction is with the immune system:

Our bodies have specialized immune cells called macrophages, responsible for detecting and eliminating harmful bacteria and organisms. These immune cells possess specific receptors like dectin-1 and TLR-2 that are particularly receptive to β-D-glucans, like the ones present in Reishi. 

According to a 2021 review, Dectin-1 activation is responsible for eliminating pathogenic microorganisms that may invade the body. Toll-like receptors (TLRs), on the other hand, initiate the innate immune response during the early stages of infection. β-D-glucans bind with both receptor sites in a way that activates the innate immune system, inducing the production, growth, and activity of other immune cells.

Gestational diabetes mellitus (GDM) refers to glucose intolerance recognized during pregnancy. GDM increases the risk of high blood pressure, preeclampsia, or eclampsia during pregnancy, along with a higher risk of developing type 2 diabetes or cardiovascular disease later in life. 

Managing blood sugar through diet and exercise is crucial, and incorporating reishi may provide added support in reducing the risk of GDM. 

According to research, Reishi mushroom compounds showcase hypoglycemic effects by elevating insulin levels and lowering plasma sugar levels, as observed in animal studies. Moreover, a study conducted on pregnant mice demonstrated that reishi could modify glucose metabolism, reduce lipid peroxidation, and enhance fetus health, reducing  long-term health risks.

Of course, animal studies do not tell us everything we need to know about how Reishi will affect pregnant mothers who are dealing with or at risk for gestational diabetes. Keep in mind that it may interact with some medications, so it shouldn't be used alongside other diabetes medications without a doctor's guidance.

High blood pressure is a concern during pregnancy, especially with GDM, which further elevates the risk. 

Research suggests that reishi could be a potential source of hypotensive peptides, meaning it may help to regulate blood pressure. Additionally, a mushroom-rich diet of 100 grams per day during pregnancy has shown promise as a preventive strategy for lowering the risk of pregnancy-induced hypertension.

Pregnancy often involves weight gain, but excessive gain beyond medical recommendations poses health risks for both the mother and the child. Obesity is frequently linked to low-grade inflammation and disruptions in intestinal microbiota.

According to one study, Reishi demonstrated efficacy as a prebiotic agent, countering gut dysbiosis and reducing the incidence of obesity. Notably, the study also highlights reishi's impact on weight regulation is also attributed to its ability to manage blood sugar levels and reduce inflammation within the body.

Ensuring good mental health and quality sleep are paramount for overall well-being during pregnancy. Anxiety and insomnia are common issues during this time, often interlinked and exacerbating each other.

Reishi has exhibited anxiolytic effects in research studies, primarily attributed to its phenols and flavonoids content. Anxiety frequently disrupts sleep due to racing thoughts and excess worrying.

Reishi's relaxing properties were further investigated for their impact on sleep and its different phases. The study revealed that reishi could increase total sleep time and the length of non-rapid eye movement sleep (NREM sleep), promoting more restful sleep.

While reishi mushrooms have shown promise in various areas of health, there are potential mushroom supplement side effects to consider–especially during pregnancy.

One notable consideration is the possibility of reishi mushrooms affecting blood clotting due to their natural anticoagulant properties. Pregnant individuals, especially those with a history of clotting disorders, should exercise caution and consult their healthcare provider before incorporating reishi mushrooms into their diet.

Another concern lies with those who have immune system disorders. Reishi can augment immune function, which can be serious for those dealing with an autoimmune disorder. In fact, those with autoimmune disorders should avoid Reishi unless otherwise instructed by their doctor.

Finally, like all mushrooms, Reishi carries a considerable risk of allergic reaction in those who are allergic to mushrooms. If you've never had mushrooms before and don't know if you are allergic, you may want to avoid them during pregnancy and try them when your pregnancy is over.

Reishi may interact with medications, affecting their efficacy or causing adverse reactions, especially in individuals on anticoagulants or blood pressure medications.

In rare cases, reishi consumption may be associated with liver issues, although this is uncommon and usually occurs with excessive or prolonged use.

It's important to consult a healthcare professional before adding reishi mushrooms to your diet, especially if you have pre-existing medical conditions or are taking medications.

If you're an expectant mother intrigued by the potential benefits of reishi mushrooms and contemplating their inclusion in your diet, here are some tips to help you make an informed decision:

• Consult Your Healthcare Provider: Before introducing reishi mushrooms or any new supplement into your diet during pregnancy, seek advice from your obstetrician or healthcare provider to ensure it aligns with your specific health circumstances.
• Choose a High Quality Supplement: If using reishi supplements for therapeutic benefits, look for one that is made from reishi extract, not whole mushroom powder. You may also avoid dual extracted products, as they are less effective. 
• Moderation is Key: If your healthcare provider gives the green light, consume reishi mushrooms in moderation. Avoid excessive amounts and keep your overall diet well-rounded and diverse.
• Monitor for Reactions: Pay close attention to how your body reacts to reishi mushrooms. If you experience any adverse effects, cease consumption and consult your healthcare provider immediately.

If you're drawn to the potential benefits of reishi mushrooms, discussing it with your healthcare provider is paramount. Together, you can weigh the pros and cons based on your individual health history and circumstances. 

Remember, your well-being and that of your developing child are of the utmost importance. Thus, making well-informed decisions that prioritize safety and health is the most prudent approach.
