Side Effects Of Mushroom Supplements

Side Effects Of Mushroom Supplements

Mushroom supplements, like herbs, are naturally sourced, which can cause an adverse reaction in some people. Some possible side effects of mushroom supplements are:  

1. Effects related to dosage

Too much of a good thing can have negative results, while not enough can have the opposite effect. Likewise, exceeding the daily recommended dose of mushroom supplements can have short-term adverse effects, particularly digestive problems.

The typical dose of a mushroom supplement is 2000 mg. This is the amount recommended by research for optimal health benefits. Always consult your healthcare provider if you want to exceed this amount.

2.Effects due to the source of a mushroom product

Since most medicinal mushrooms grow in nature, their environment may impact them. For example, they may, over time, gather and accumulate heavy metals, toxins, and pesticides from their growth environment because they are bio accumulators.

You must consider the source of the mushrooms if you want to ensure the safety and purity of the mushroom supplement product. Look for functional mushroom supplements that are grown and processed in a way that removes harmful toxins, heavy metals, and pesticides.

3. Side effects related to medications

Avoid medicinal mushrooms if you take blood sugar or blood pressure-lowering medications. This is because functional fungi can have sugar and pressure-lowering effects, which can be dangerous if you take medications that also have the same impact. As the results of the two add up, the levels can get dangerously low.

Likewise, some mushrooms interfere with the blood clotting process. Therefore, taking these fungi with blood thinning medications can also lead to adverse effects.

So, always check with your healthcare provider if you are taking medications and want to begin medicinal mushroom supplements.

4. Other side effects

Unfortunately, there are situations where health benefits can turn into adverse effects. For instance, some mushroom powder supplements support concentration and stimulate focus.
