Omega-3, especially DHA, plays a vital role in fetal brain and eye development during pregnancy, especially in the second and third trimesters. Since you are vegetarian and sensitive to dry fruits, a plant-based DHA supplement would be ideal for you. Thankfully, there are several good algae-based (vegan) DHA capsules available that are completely free from fish oil and allergens.
Next Steps
Consult Your Gynaecologist before starting any supplement, even if it's plant-based.
Health Tips
Always check that the supplement is marked “pregnancy safe” and is free from mercury and heavy metals.
Store in a cool place to prevent spoilage.
