So you’re thinking about incorporating turkey tail mushrooms into your daily routine, but are wondering if there are any side effects or potential drug interactions to consider.
You’ve come to the right place!
It’s always important to consult both your physician and pharmacist before incorporating natural remedies into your daily routine. And it’s important to note that due to an overwhelming lack of scientific study, we still aren’t 100% sure what side effects or interactions there are when taking turkey tail supplements.
But this blog will act as a great starting point for a conversation with your doctor.
In this post, we will discuss turkey tail’s side effects, dosing requirements, and toxicology (or lack thereof). Let’s dig a little deeper into the topic and discuss what we know about turkey tail today.
First, let’s quickly review:
Turkey tail mushrooms (Trametes versicolor) are considered one of the most well-documented and important edible medicinal mushrooms for immunotherapy and cancer care. A great starter mushroom to collect while foraging in the wild, turkey tail can be found growing on decayed logs in forests all over the globe and is not specific to a certain type of tree. (Remember to work with a professional mycologist before foraging by yourself!) You will most likely find turkey tail growing on hardwoods, like oak trees.
Turkey tail fruiting bodies taste sweet and mild and are sold commercially as a tincture, tea, or capsule across North America, Asia, and Europe.
Turkey tail mushrooms have been used as a cancer treatment for over 30 years in Japan. In more recent years, this mushroom has made its way onto the Western world’s radar and the multicolored species has been studied in numerous clinical trials. These studies have found that turkey tail contains one of the highest percentages of beta-glucans (more than 50% of the mushroom’s makeup), and it’s also been found that the Polysaccharopeptide-K (PSK) concentrate derived from turkey tail enhances immune function.
Furthermore, turkey tail has been shown to help with:
In a Japanese postoperative study on the effects of PSK on gastric cancer, it was shown that the group given mitomycin C (MMC), futraful (FT), and PSK (e.g., turkey tail concentrate) had the best survival rate with positive lymph node metastases. This promising study, along with many others, is paving the way for more possibilities to use turkey tail for positive health outcomes.
But there is still a lot to learn about this mushroom.
Although many studies on turkey tail mushrooms have shown promising results for cancer treatment, immunotherapy, preventing and treating upper respiratory, urinary, and digestive tract infections, and cholesterol regulation, it is not FDA approved at this time. Because the mushroom is edible, the lack of FDA approval is less concerning and it’s been shown that there are very few, if any, adverse side effects when taking turkey tail, making it a very safe mushroom to consume.
With all of this in mind, it’s still important to consider that turkey tail consumption affects each person differently.
People who have pre-existing health conditions or are allergic to mushrooms or mold should consult a trusted healthcare professional before consuming turkey tail.
The six documented potential side effects of taking turkey tail include:
Also, it’s generally recommended to avoid taking turkey tail mushrooms if you are pregnant or breastfeeding.
The good news is that, even with side effects presenting themselves in some cases, it’s never been documented that someone has had irreversible side effects from taking turkey tail.
Out of all the research conducted on turkey tail mushrooms, reputable information on possible Rx drug interactions is lacking. Today, there have been no reported negative interactions when traditional medications and turkey tail have been taken in tandem, but that doesn’t mean it’s impossible. If you are taking medication and would like to start taking turkey tail, consider talking to your doctor before you start dosing regularly.
As with anything, dosage can differ person-to-person based on size, weight, and tolerance. When starting to take turkey tail, it’s recommended to use 1-3 grams of powdered extract daily. For capsule supplements, start by taking two “00” supplements per day (e.g., two 400-500 mg). After taking turkey tail for some time, if a higher dose is desired, you can double the amount.
If you’re considering taking turkey tail to enhance cancer treatment or aid in a cancer diagnosis, it’s recommended to first consult your doctor. If they agree that’s a good choice for your health, it’s recommended to take 3 grams of turkey tail PSK concentrate per day alongside traditional chemotherapy.
