Pharmaceutical grade is very expensive. For 90-120 tablets, supplements will cost in the range of RM200-RM400 per bottle. I only know of one brand in Malaysia which is USANA.

For the lower grade ones, the price is much cheaper and these supplements are the ones you find at pharmacies like 21st Century, Kordel, Blackmores, etc.

I'm recovering from a bad immune system so I have to take more supplements. I went for the cheaper option because the quantities I'm taking is a lot more. ATM, it's 4000 mg of Omega 3 (Blackmore fish oil and Kordel's Wild Salmon oil) but in the evening, I take 2000 mg of Omega 3, 6, 9 (Udo's Oil in capsule form).

Note : I'm doing this under supervision so I wouldn't advise you take the same dosage of me without someone monitoring you.

3x a day . Each time 2 tablets of 1000 mg each.

Every 3 months, I rotate the brands so that my immune system doesn't build up an immunity towards it.

Because of the high amount I take, I usually buy from the pharmacy and rotate brands. Cheapest one in KL is probably AA pharmacy. They sell in bulk and you can ask for 10% discount (can negotiate more if you can persuade them by buying in bulk).
