Overview
NOW Foods Ultra Omega-3D combines fish oil with vitamin D-3 in a 180-softgel bottle marketed for cardiovascular support. It is formulated corn-free, dairy free and egg free, and is certified halal, keto friendly and kosher.
Adding vitamin D-3 to a fish oil softgel is a common pairing, letting one softgel cover two nutrients often taken together for heart and bone-related support. The halal, keto and kosher certifications broaden who can use it compared with a plain fish oil, though as a fish-derived product it is not suitable for anyone with a fish allergy.
- 180 softgels per bottle
- Fish oil plus vitamin D-3
- Halal, keto, kosher certified
- Corn-free, dairy free, egg free
Who it's for
Fits buyers wanting fish oil and vitamin D-3 combined in one softgel, including those who need halal, kosher or keto-compliant supplements. Not appropriate for anyone with a fish allergy, since the product is fish derived.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines fish oil and vitamin D-3 in one softgel
- Halal, keto and kosher certified
- 180 softgels for extended use
- Not suitable for fish allergies, since it is fish derived
- No listed EPA/DHA or vitamin D-3 milligram amounts
Performance notes
Pairing vitamin D-3 with fish oil in one softgel lets buyers cover both nutrients without a second bottle. At 180 softgels, the bottle offers a longer supply than the smaller counts common in this category, though the daily serving size determines how long it actually lasts.
