This is an average, affordable, and straight forward supplement. If that sounds like what you’re looking for, well then, Swanson Full Spectrum Lion’s Mane Mushroom might be the right product for you. If you like gelatin capsules and have most of your lion’s mane mushroom to be a blend of rice and grain concentrates (according to many customer reviews), Swanson Full Spectrum Lion’s Mane Mushroom is for you. If, however, you would rather spend a little bit more on a higher quality product that has a more potent formula, you should take a look at some of the top rated brands we reviewed. The bottom line is that this supplement is pretty cheap, both in price and potency, but the brand is well known and there is a large subset of people that will really like this product simply because the brand is one of their favorites.


  • Contains 500mg of Lion’s Mane Mushroom (Hericium erinaceus) (Mycelium biomass) per serving
  • Other ingredients: Gelatin, rice extract blend, rice flour, rice concentrate, microcrystalline cellulose (plant fiber).


  • Dosage is on par with other leading brands in the category, however the potency isn’t quite where we would like to see it.
  • Doesn’t have the high beta-glucans content we like to see in high quality lion’s mane supplements
  • Rice extract blend, rice flour, and rice concentrate is not ingredients you want to see in your mushroom supplement, usually a sign of lower overall potency


  • Gelatin, rice extract blend, rice flour, and rice concentrate are several of the ingredients we rate very critically when we see these in a supplement or product.
