How to Choose the Best Fish Oil Supplements for Safe Intake?
Cryoviva Singapore (a stem cell preservation bank trusted by many parents across Singapore) says, while fish oil is safe, you need to consider its quality.
Always look at these qualities before buying it:
- Third-party tested for contaminants such as mercury, PCBs, dioxins, and heavy metals.
- Look for a “Non-GMO Verified” label to rule out any genetic modification concerns.
- High DHA content (at least 200-500 mg per serving) for maximum cognitive and cardiovascular benefits.
- It should be its natural triglyceride (rTG) for superior absorption over ethyl esters.
- Low oxidation levels (total oxidation, TOTOX < 26) to avoid rancidity (the process where fats and oils in food get spoiled).
Recommended Intake (Dosage) of Fish Oil for Omega-3s During Pregnancy
Always consult your doctor nearby in Singapore to know the accurate dosage of Omega-3s during pregnancy.
The general recommendations for pregnant women, trimester-wise, are:
Trimester | Suggested DHA Intake |
1st | 200-300 mg daily |
2nd/3rd | 300-650 mg daily |
Lactation | 500-1000 mg (or higher) |
What Are Good Sources of Omega-3 Besides Fish?
Here are some other sources of Omega-3. However, ask your doctor if you can take them during pregnancy or not for safety reasons.
Seeds & Nuts

- Chia Seeds
- Hemp Seeds
- Walnuts

Note: Pregnant women, women planning pregnancy, and young children are most vulnerable to the negative effects of mercury. It can damage the developing brain and nervous system, so they should avoid high-mercury fish entirely.
