The effect of cold water loading to promote the recovery of peripheral body temperature

When 9 healthy male subjects ingested 2000 FU of Nattokinase, the skin temperatures of the right middle finger, palm, and back of the hand recovered more rapidly with Nattokinase ingestion than the placebo group. In humans, a single oral dose of Nattokinase was proven to promote recovery from a cold-induced decrease in peripheral skin temperature.
