We don’t recommend a specific time of day, but we do recommend that you take your omega-3 with a meal rather than on an empty stomach.
Don’t Take Omega-3 on an Empty Stomach
There are two reasons for this.
- The first is that omega-3 supplements are more easily tolerated with food than on an empty stomach.
- The second is that when taken with a meal, omega-3 fatty acids are better absorbed. This is because the fat in a meal stimulates the pancreatic lipase enzymes. The more enzyme activity, the more completely the omega-3 triglycerides are broken down and then absorbed in the small intestine .
That’s why there’s no best time to take omega-3 fish oil. Though, you should take fish oil with a meal for maximal absorption.
Take Omega-3 with a Meal That Contains Fat
The key point for full absorption of fish oil is that it is the fat consumed in a meal that stimulates the release of these digestive enzymes. Any meal that you take your omega 3 with needs to contain some fat to maximise absorption.
For example, one study tested absorption rates of omega-3 (DHA and EPA) with either a high fat meal (44g of fat), or a low fat meal (8g of fat). The results showed that the high fat meal caused 300% more omega-3 absorption . Another study found an even greater effect and recorded a 400% increase in the absorption rates of omega-3 when taken with a high fat meal .
Fat and Cholesterol Are Necessary for Optimum Health
If you already enjoy fat as a regular part of your diet — great. However, if adding fat to your meals make you feel uncomfortable, I can understand why. Unfortunately, saturated fat and cholesterol have been largely demonised in the current medical guidelines, and many doctors recommend eating as little fat as possible.
This is actually grossly unfair and has never actually been based on any reliable scientific evidence, and has arguably significantly contributed to the obesity, heart disease and diabetes epidemic. Fat and cholesterol are necessary for optimum health and performance and should form part of everyone’s diet.
