You will want to go for high DHA.  I wouldn't touch blackmore. Why?

Furthermore fish oil sold in malaysia are most likely in ethyl ester (EE) form (cheaper to produce with lower absorption). Also, how do we know that their claim that their fish oil is free from pollutants is true and freshf? Unless they can produce a certificate of analysis (have to email the company) or tested by IFOS, then it's ok.
For me,when I buy fish oil I look at 2 things
a) must be in triglyceride form (as how it occur in nature - more stable and better absorption)
b) must pass IFOS test.

A rancid + contaminated fish oil do more harm to the body than  good.

For me, personally, I only buy Carlson and Nordic Naturals.

if you want oil; consume coconut oil

get fish oil by eating fish, its readily available & better in absorption

One I only take fish oil which are certified by IFOS. Manufacturer can said they are the freshess, no contamination, blah blah. But do they have proof to prove their claim? A fish oil manufacture which cannot produce a certificate of analysis (email them for it) should start ringing some alarm bells as they have something to hide. IFOS is 3rd party.
Second, IFOS certified both ethyl ester and triglyceride fiah oil. I only take triglycerides fish oil as they are much more stable (won't go rancid so fast), better absorbed and exist in nature as triglycerides. Ethyl ester fish oil are cheaper to produce but more prone to oxidation (bad thing) and is less absorbed by the body.
Third, their DHA-EPA contents are pretty high when you compared to fish oil sold in malaysia pharmacies. (you need lesser softgels to meet the min amount per day)
In the US, Nordic is like the gold standard for fish oil. If you money is not an issue to you, take Nordic.  If you are on budget, take Carlson.

Hope this answer your questions.

Can you share what you read?  I'm interested.  Coz when I was pregnant, my OB-Gyne prescribed fish oil in my last 2 weeks of pregnancy.

the recent reserch shows that fish oil has no benefits
