so far I've read that Barleans with lignans is the best in terms of quality in the US, and it's organic/cold pressed, unfiltered.
I am not sure if you can find it in your country, but you may want to call them and ask if they would ship overseas: www.barleans.com

If you call Barleans directly and tell them that your son has cancer, they will give a special price for cancer patients. It's almost half price you pay in the store.

Hope this helps and I hope the best for your son.

If you can't find it in a health food store near you then search for it online. There are many websites that sell it.

There is one manufacturer of Flaxseed Oil in India who should be able to ship to you in Muscat. Mulkusha Natural Oiltek is the name. Email: mulkusha@ec21.com
Good luck

Hi,
I am in Oman and have read your requirement for Flax seed oil for your son. I am also in search of Flax seed oil for my daughter. Pls let me know if you found a company that sells flax seed oil in Oman.
Thanks,
