How to Smartly Choose Omega-3 Supplements
Hello. This is Gangnam Smile Eye Clinic, helping you rediscover the happy smile that comes from the joy of seeing!
In our previous post, we explored the benefits of Omega-3 for dry eyes.
Omega-3 is beneficial not only for dry eyes but also for various retinal diseases (macular degeneration, diabetic retinopathy).

Omega-3 is also included in the AREDS2 formula, which determines the types and amounts of nutrients essential for patients with macular degeneration.
Unlike dry eyes, retinal diseases often have no early symptoms, making prevention the best approach.
Which Omega-3 supplement is best to take?
Let's find out how to choose a good Omega-3 supplement with Gangnam Smile Eye Clinic.

Omega-3 should be checked by its DHA and EPA content, not its total intake.
The recommended daily dose of Omega-3 is 1,000mg or more, and for eye health benefits,
the sum of DHA and EPA should be at least 600mg.
When choosing an Omega-3 supplement, the higher the content of DHA and EPA, the essential components of Omega-3, the better, right?

Omega-3 must undergo a refining process to remove toxins from the raw material, and this process is divided into three generations.
1st generation Omega-3 has a DHA + EPA content of about 30%.
2nd generation Omega-3 increased the DHA + EPA content to 60%, but the actual absorption rate may be lower than 60%.
3rd generation Omega-3 is called rTG (Re-Esterified Triglyceride),
and it has the highest DHA + EPA content and actual absorption rate.
As confirmed above, it is best to take 3rd generation Omega-3, which has the highest content and actual absorption rate, isn't it?

The Omega Index Test (fatty acid analysis test) can comprehensively check the ratio of 24 types of fatty acids with just 3-4 drops of blood.
Through the Omega Index Test, you can find out which essential fatty acids your body is lacking,
and what percentage of unhealthy saturated & trans fatty acids are in your body.
Let's Prevent Retinal Diseases with Omega-3!
Many eye supplements sold on the market do not contain Omega-3. Therefore, if you have retinal diseases such as dry eyes, macular degeneration, or diabetic retinopathy, we recommend taking Omega-3 together.
At Smile Eye Clinic, you can confirm the deficiency of essential fatty acids and improvement with supplement intake through a simple Omega Index Test (fatty acid analysis test), and receive professional consultation on various retinal diseases and eye supplements.
