Description of intervention(s) / exposure
The aim of this study is to look at the effects of ingesting seaweed fucoidan (GFS) on the mobilisation/release of haematopoeitic progenitor stem cells from bone marrow to the peripheral blood and to study its effects on modulating the immune system. This will be important in treatment following autologous transplantation, AIDS and cancer patients.

Investigational Arms:
1. 3g of 10% GFS/Day for 12 days
2. 3g of 75% GFS/Day for 12 days
3. G-CSF treatment
