7 Signs You Need More Omega-3s for Your Health

Did you ever think you could have a fat deficiency? Current research shows you are most likely deficient in omega-3s, and these signs and symptoms could mean you need more omega-3 fats from nutrition therapy.

Omega-3 fats are a family of fats that are essential for health. Since our bodies can’t make these fats, they must source them from our diet. Despite eating a balanced diet, most people in Canada and US (along with other Western countries) have very low levels of omega-3s as measured by a simple blood test.

Because omega-3s are essential for countless body systems, there are seven common signs that you might need more omega-3s to achieve optimal health.

Skin health

Do you have dry, itching, or flaky skin? This could be a sign that your skin cells do not have enough omega-3s. This essential fat is a key component of the structure of our skin cells and every cell throughout the body.


Omega-3s work to resolve inflammation. In fact, these essential fats work on the same pathways as NSAID drugs (e.g., ibuprofen). While omega-3s do not provide the same acute response as these drugs, they are important for addressing systemic inflammation over the long term.

Nerve Pain

Omega-3s are essential for the development, maintenance, and regeneration of nerves. Individuals with nerve damage and nerve pain have lower omega-3s compared to those without nerve damage. Omega-3s can also be used as a therapy to support the recovery of damaged nerves.

Mood and Depression

The brain has the highest concentration of omega-3 fats in the body. Low omega-3 status is consistently associated with depression; omega-3 therapy has been included in clinical practice guidelines for addressing depression along with other mental health conditions including ADHD.


Did you sleep well last night? Ongoing fatigue could be a sign of low omega-3s. While omega-3s are essential for brain health, emerging research shows higher omega-3s levels can lead to improved sleep and restfulness.

Blood Flow

Cold hands and feet could be a sign of low omega-3 levels. Omega-3s are important for the flexibility of cells in our body, especially blood vessels. Without enough omega-3s, the structure of blood vessels can become rigid. Omega-3s can also support blood vessel dilation from the release of nitric oxide.

Dry Eyes

Omega-3s play a key role in eye health, including macular health and tear production. Consistent clinical research has shown that omega-3s can be used to reduce dry eye symptoms, which can become more common as we age.

Omega-3s are essential for good health. Without enough of these fats, our bodies don’t function optimally. If you have noticed any of these signs or symptoms, it may be time to review your omega-3 intake and consider omega-3 nutrition therapy with your healthcare provider.
