Great product! I got this for my mom, she is going through chemo, she has been eating it since August 2020. It helps my mom recover from the chemo. Before taking this product, my mom had to stop taking chemo after two treatments because the recovery was not quick enough. We saw an article on the newspaper about fucoidan and its benefits and started looking for this kind of supplement. We looked through many similar fucoidan supplement and decided to try this one out even it was the most expensive one at the time we purchased. It worked, after taking it for one and half week, in the next blood test, the doctor told my mom to continue the chemo treatments because everything went back to standard. Since then, my mom never had to stop taking chemo treatment to wait for recovery. Like I said, this product is expensive but it does help people who is going though chemo, if you have the budget, you can add this to your daily supplement. PS: while taking this supplement, my mom also eats a lot of fruits and vegetables, she also does daily exercises.
