When selecting fresh shiitake mushrooms to incorporate into your diet, there are a few key criteria to consider. First, check for firm and plump caps that are dry to the touch. Avoid mushrooms that are slimy or have a sticky texture, as these are signs of spoilage. 

The color of the caps should be dark brown with white or light brown gills underneath. Additionally, it's best to choose shiitake mushrooms with the stems still attached, as they can also be used in cooking and add flavor to dishes.

In terms of nutrition, shiitake mushrooms are a healthy addition to your diet. They are low in calories, a good source of carbohydrates, and provide a small amount of protein and fat. They are also rich in various vitamins and minerals.

When incorporating shiitake mushrooms into your diet, consider various cooking methods.

You can save the stems for making vegetable broth or discard them if they are too woody.

What to Look for in Shiitake Mushroom Supplements

As far as supplements go, you’ll want to choose high-quality supplements that use the fruiting body and stems instead of filler ingredients that cut down production costs but leave you with a lower-quality supplement. 

Here are some things to look for in shiitake mushroom supplements:

  1. Quality and Purity: Look for a supplement made from high-quality mushrooms. Ideally, the mushrooms should be grown organically to minimize exposure to pesticides and other harmful substances.
  2. Mushroom Species: Different mushroom species have varying health benefits, so choosing a supplement that contains the specific mushroom species you're interested in is important. For example, if you're looking for shiitake mushroom benefits, make sure the supplement contains shiitake extract or powder.
  3. Extract vs. Whole Mushroom: Some mushroom supplements use extracts, which concentrate on the bioactive compounds of the mushrooms, while others use whole mushrooms. Both options can be effective, but knowing which form you prefer and what scientific evidence supports its efficacy is important.
  4. Bioavailability: Consider the bioavailability of the supplement, which refers to how easily the body can absorb and utilize the active compounds in the mushrooms. Some supplements may contain additional ingredients or extraction methods that enhance bioavailability.
  5. Dosage and Recommended Use: Check the dosage and recommended use provided by the manufacturer. Ensure the supplement provides a dosage that aligns with your specific needs and follows the instructions for optimal benefits. Not every supplement brand is the same. 

As always, it's a good idea to consult with a healthcare professional before starting any new supplement, especially if you have any underlying health conditions or are taking other medications.
