In a world jam-packed with biohacking solutions, it comes as no surprise that we are constantly looking for ways to optimize our health and brain function. However, it’s not necessarily all about biohacks. Simply eating a balanced and healthy diet goes a long way. In fact, omega-3s play a major role in preventing cognitive decline. So, let’s dig a little deeper into how omega-3s and brain health are intricately linked.

If you want to age gracefully with a sharp mind, you’ll want to keep reading. We’ve got some facts you won’t want to miss. We’ll also explore the difference between omega-3, omega-6, and omega-9, the benefits of omega-3s, the risks associated with an omega deficiency, and more. 

What is the Difference Between Omega 3, Omega 6, and Omega 9?

Omega-3s are essential fatty acids that must be obtained through the food you eat. They include alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Omega-6 fatty acids, on the other hand, include arachidonic and linoleic acid. Both omega-3s and 6s are polyunsaturated fats.

Meanwhile, omega-9 is a monounsaturated fat. This fatty acid can be made within the body, which means it’s a non-essential fatty acid and doesn’t have to be obtained through your diet.

Usually, it’s recommended to have the optimal omega-3-6-9 ratio be 2:1:1. Some experts even go so far as to recommend an omega-3 to 6 ratio between 2:1 and 4:1. However, this may come down to individual needs and what makes you feel your best. Often, it’s wise to start with a lower amount and slowly build up your dosage, if needed.

The Benefits of Omega 3

Omega-3 fatty acids are polyunsaturated fats. Most commonly found in fish, nuts, and seeds, this nutrient has various benefits, including:

Undeniably, there is great importance when it comes to ensuring you get enough omega-3s in your diet. Yet, what happens when you don’t get enough?

Omega Deficiency Symptoms and Risks

An omega-3 deficiency can arise from not eating enough omega-3 foods, such as fish or shellfish. When it comes to Omega-6s, many people tend to get too much in their diet through the consumption of various cooking oils. Yet, as mentioned above, you’re actually supposed to get twice as many omega-3s.

So, how do you know if you have an omega-3 deficiency? Some of the most common symptoms include:

  • Dry skin
  • Depression
  • Dry eyes
  • Joint pain
  • Hair loss or hair thinning
  • Poor circulation
  • Heart issues
  • Fatigue

Additionally, an omega-3 deficiency can increase your risk of heart disease, joint issues such as arthritis, allergies, mental health problems, and even neurodegenerative disorders such as dementia and memory loss.

The Best Ways to Increase Omega 3 Levels

As with most nutrients, the best way to increase your omega-3 levels is by eating more food containing omega-3. Some examples include:

  • Salmon
  • Mackerel
  • Tuna
  • Flaxseeds
  • Chia seeds
  • Walnuts
  • Canola oil
  • Flaxseed oil

Usually, it’s recommended to eat about eight ounces of fish a week to obtain adequate omega 3s.

If these aren’t readily available to you, you might find it easier to supplement omega-3s. There are a variety of options available online or at your local pharmacy or grocery store. You can also purchase supplements with all three omega fatty acids including adequate ratios.

At the same time, you need to be careful regarding omega-3 consumption due to heavy metal toxicity in some supplement brands. Additionally, omega-3 supplementation is not suitable for individuals taking blood clotting medication due to potential interactions. Further, some experts warn against over-supplementing and encourage obtaining as many nutrients as you can from food.

Is Heavy Metal Toxicity an Issue When Taking Omega 3?

Heavy metal toxicity is an issue with some omega-3 supplement brands. This is why it always pays to do your due diligence and research any product before buying. Fish oils containing omega-3s might include mercury, lead, cadmium, and arsenic. Generally, this means you need to find a supplement that has been purified and tested to avoid these toxins. 

Some of the best sources of heavy metal-free omega 3 supplements include:

The above supplements have been tested and purified, claiming to be free from any heavy metals or toxins which make them an ideal choice compared to other options on the market.
