At first read, an Omega 3-6-9 supplement sounds more comprehensive than an Omega-3 supplement—especially since the labels often make similar claims. But more doesn’t always mean better. it’s fair to wonder: do you need the full trio, or is Omega-3 on its own the better choice when you are trying to conceive or already pregnant?

The answer comes down to what each fatty acid does, where you are likely already getting it, and what the research says about fertility and pregnancy specifically. Here is a clear breakdown of the difference between Omega-3 and 3-6-9 so you can make an informed choice.

All 3 are unsaturated fatty acids (healthy dietary fats), but they play very different roles in the body. Understanding those differences helps explain why more is not always better.

Omega-6 is an essential fatty acid, meaning your body can’t make it on its own. It supports cell growth, energy production, and immune function. The main forms include linoleic acid and arachidonic acid.

Here is the catch: Omega-6 is everywhere. Vegetable oils, processed foods, nuts, seeds, and many meats are rich in it. Most people following a Western diet get far more Omega-6 than they need. The ideal ratio of Omega-6 to Omega-3 is somewhere around 4:1, but modern diets often push it to 15:1 or higher. That imbalance may promote inflammation, which is the opposite of what you want when you are trying to conceive. 

Omega-6 (and its sources) aren’t “bad,” (contrary to popular opinions about seed oils—read more here) and you do need this ingredient—but the balance between Omega-3 and Omega-6 is important when it comes to fertility and overall health.

Unlike Omega-3 and Omega-6, your body can produce Omega-9 on its own. The most common form is oleic acid, found abundantly in olive oil and avocados. Omega-9 may support heart health and a healthy inflammatory response, but since your body synthesizes it and most diets supply plenty, supplementing with it is rarely necessary.

DHA is a type of Omega-3. It’s the form that matters most during pregnancy because it’s an important building block of the baby's brain and retina.

ALA from plant sources (like chia seeds and walnuts) areis also Omega-3s, but the body converts ALA to DHA and EPA inefficiently (often less than 5%). That’ is why many fertility specialists recommend getting DHA directly from fish or algae rather than relying on plant-based ALA alone.

Probably not. Omega-3-6-9 supplements were designed to provide all 3 fatty acids in 1 capsule. But since most people already consume more than enough Omega-6 through diet, adding more through a supplement can actually push the ratio further out of balance. And Omega-9, as a non-essential fatty acid your body already makes, rarely needs supplementation.

For fertility and pregnancy, the research consistently points to Omega-3 (specifically DHA and EPA) as the fatty acid worth prioritizing. It may help support egg and sperm quality, hormone regulation, and implantation. During pregnancy, adequate DHA is essential for fetal brain development.

The Male Fertility Power Pack also includes DHA alongside other nutrients that may support sperm health, because fertility involves both partners.

Both can deliver meaningful amounts of DHA and EPA. Fish oil has been the traditional source, but algae-based DHA has gained popularity for several reasons: it is vegan, it avoids concerns about heavy metals in fish, and it skips the fishy aftertaste that can trigger nausea during pregnancy.

Bird&Be uses algae-sourced DHA in all of its prenatals, making it accessible regardless of dietary preferences. If nausea is a factor, the Gentle Prenatal Pack includes the essentials, including Omega-3, with an extra dose of B6 (the main ingredient in morning sickness meds) to be even gentler.

For most people, no. The best Omega for pregnancy is a targeted Omega-3 supplement with adequate DHA, ideally 200 to 300 mg per day or more. Getting Omega-6 and Omega-9 through a balanced diet (olive oil, nuts, seeds, eggs) is usually sufficient.

In fact, some experts suggest that Omega-3-6-9 combo supplements may not be appropriate during pregnancy because the added Omega-6 can contribute to inflammation rather than reduce it. A focused Omega-3 approach, paired with a well-formulated prenatal, is a simpler and more evidence-aligned strategy.

When it comes to fertility and pregnancy, the most important fatty acid to supplement is DHA, and the most effective way to get it is through a quality Omega-3 source. Your prenatal may already include it.

Most health organizations recommend at least 200 to 300 mg of DHA per day during pregnancy. Some fertility specialists suggest higher amounts depending on your diet and health profile. Talk to your provider about the right dose for your situation.
