Fungal Species: Agaricus bisporus (white button, crimini, portabella)

Metabolomics Profiling of White Button, Crimini, Portabella, Lion’s Mane, Maitake, Oyster, and Shiitake Mushrooms Using Untargeted Metabolomics and Targeted Amino Acid Analysis

Researchers analyzed seven popular mushroom varieties to understand their chemical makeup. They found over 10,000 different compounds across all mushrooms, with each variety having its own unique set of chemicals. Lion’s mane and oyster mushrooms were particularly rich in L-ergothioneine, a special amino acid thought to have antioxidant and anti-aging properties. The common white button, crimini, and portabella mushrooms had similar nutrient profiles, while specialty mushrooms had distinct chemical signatures.

Association of mushroom consumption with all-cause and cause-specific mortality among American adults: prospective cohort study findings from NHANES III

mycolabadmin

This study followed over 15,000 American adults for nearly 20 years and found that people who ate mushrooms had a lower risk of dying from any cause compared to those who didn’t eat mushrooms. The more mushrooms people ate, the greater the benefit. Replacing red or processed meat with mushrooms was associated with even greater longevity benefits. Mushrooms’ beneficial effects likely come from their high antioxidant content, particularly compounds called ergothioneine and glutathione.

Correction: Vitamin D4 in Mushrooms

mycolabadmin

This correction updates a scientific study about vitamin D4 found in mushrooms. Researchers found that UV-exposed mushrooms, especially maitake and special portabella varieties, contain significantly more vitamin D4 than other types. The correction clarifies measurement errors in the original publication and provides accurate vitamin D4 levels across different mushroom species available in grocery stores.
