Skin Repair

In a controlled human study daily consumption of 320 mg Sparassis crispa fruiting body by healthy volunteers over a period of 28 days dramatically reduced transepidermal water loss in the treatment group with no change in the control group, indicating enhanced skin integrity, and in vivo studies show increased collagen production and enhanced wound healing from S. crispa supplementation1-3.

Although 320mg/day was shown to enhance skin integrity, higher doses may be necessary with in vivo studies showing enhanced collagen synthesis at 70mg/kg b.w.
