Short answer: Yes — absorption varies based on the form of omega-3 (triglyceride vs. ethyl ester), whether it's taken with food, individual digestion, and other factors. Taking a supplement doesn't guarantee it's being absorbed and used effectively; testing your ratio is the only way to confirm it.
Not all omega-3 supplements are absorbed the same way. Form matters — some formulations are generally better absorbed than others. Taking it with a meal containing some fat can improve absorption compared to taking it on an empty stomach. Individual digestive function also plays a role, and this varies naturally from person to person.
There's no obvious sign that absorption is underperforming. You take the supplement, you assume it's working, and without a number to check against, that assumption goes unchallenged indefinitely.
Take note of form and timing as a starting point — with food, in a well-absorbed form, consistently. Then test your omega-6 to omega-3 ratio to see the actual outcome, rather than assuming absorption is happening the way you hope.

Does taking omega-3 with food really matter?
Taking it alongside a meal containing some fat is generally associated with better absorption than taking it alone.
Are all omega-3 supplement forms absorbed the same way?
No — different forms (such as triglyceride vs. ethyl ester) can differ in how well they're absorbed.
How would I know if my absorption is an issue?
Testing your omega-6 to omega-3 ratio is the most direct way to check the actual outcome.
Can digestive issues affect absorption?
Individual digestive function can play a role in how well any supplement is absorbed.
