Confusing Omega 3's. Ignore capsule size!
How much Omega 3 should I take for dry eye?
Simple question but the answer is a bit complex. Omega 3 supplements vary widely in their potency.
The following information is what I recommend in clinic. It is not applicable to everyone and talk to your eye care provider for more individualized information.
STEP 1 - Look at the label of your Omega 3 supplement and find these numbers:
Serving Size: e.g. 1,2,4 capsules
Capsule Size: e.g. 500mg to 1200mg
EPA content and DHA content in mg.
Ignore the serving size initially and find the EPA + DHA total
For dry eye, this total (EPA+DHA) needs to be 1000mg per day. Then figure out how many servings that you need to get ~1000mg/day of EPA + DHA
I often recommended up to 2000mg/day (EPA+DHA). The take away here is that the capsule size is irrelevant.
The form of the Omega 3 is important for bio-availability and triglyceride form is preferred.
See example below
On the above Krill Omega 3 label... one capsule (serving) has 75mg (EPA) + 45mg (DHA) = 120mg. For dry eye therapy I recommend >1000mg/day so... you would need 1000/120 = 8.33 ~ 8 capsules a day. (That's a lot!)
On this PRN De Omega 3 label ...
...one serving is 4 capsules which delivers 920 mg (EPA) + 920 mg (DHA) = 1840mg.
I would recommend 2-3 capsules of the PRN high potency product.
Liquid Omega 3's generally have high potency and usually 1/2 a teaspoon will achieve the ~1000mg guideline but check the label.
Most important TIP... Take with food! Without food, even the best Omega 3 will not absorb properly and not deliver the desired result!

Glaucoma and dry eye disease are conditions that have correlation but no causation. Glaucoma does not cause dry eye but these conditions often appear together... The medications used to treat glaucoma are commonly implemented as a toxic cause mild-to-moderate even severe dry eyes.
If you are currently using standard glaucoma medications then there is a very good chance that you also have dry eye issues. What can you do?
Fake or counterfeit eye-related products such as eye drops and vitamins are a relatively new phenomenon. This is dangerous not only because the content is now unknown but patients that are not receiving a proper supplement will have increased risk of vision loss.
