Omega-3 world map: 2024 update

June 2024 https://doi.org/10.1016/j.plipres.2024.101286
Jan Philipp Schuchardt a,b,*, Philine Beinhorn b, Xue Feng Hu c, Hing Man Chan c, Kaitlin Roke d,
Aldo Bernasconi d, Andreas Hahn b, Aleix Sala-Vila a,e, Ken D. Stark f, William S. Harris a,gIn 2016, the first worldwide n3 PUFA status map was published using the Omega-3 Index (O3I) as standard biomarker. The O3I is defined as the percentage of EPA + DHA in red blood cell (RBC) membrane FAs. The purpose of the present study was to update the 2016 map with new data. In order to be included, studies had to report O3I and/or blood EPA + DHA levels in metrics convertible into an estimated O3I, in samples drawn after 1999. To convert the non-RBC-based EPA + DHA metrics into RBC we used newly developed equations. Baseline data from clinical trials and observational studies were acceptable. A literature search identified 328 studies meeting inclusion criteria encompassing 342,864 subjects from 48 countries/regions. Weighted mean country O3I levels were categorized into very low ≤4%, low >4–6%, moderate >6–8%, and desirable >8%. We found that the O3I in most countries was low to very low.
Notable differences between the current and 2016 map were

• 1) USA, Canada, Italy, Turkey, UK, Ireland and Greece (moving from the very low to low category);
• 2) France, Spain and New Zealand (low to moderate); and
• 3) Finland and Iceland (moderate to desirable).
• Countries such as Iran, Egypt, and India exhibited particularly poor O3I levels.

VitaminDWiki - BARD: Omega-3 and fats

Does a person need to take Omega-3 with a fatty meal when the Omega-3 is in oil?

Yes, taking Omega-3 oil with a fatty meal is generally recommended for optimal absorption. This is because omega-3 fatty acids are fat-soluble, meaning they require the presence of fat in the digestive system to be properly absorbed into the bloodstream.

Here's why:

• Bile acids: A high-fat meal stimulates the production of bile acids by the liver. These bile acids help to emulsify and break down fats, making them easier for the body to absorb. This includes omega-3 fatty acids present in the oil.
• Micelles: Bile acids form micelles around the omega-3 fatty acids, creating a water-soluble complex that can be transported through the digestive system and absorbed into the bloodstream.
• Absorption rate: Studies have shown that taking omega-3 supplements with a fatty meal can significantly increase their absorption rate compared to taking them on an empty stomach.

Therefore, while you can still absorb some omega-3 oil without a fatty meal, taking it with a meal containing healthy fats like avocado, nuts, seeds, or fatty fish will significantly improve its absorption and maximize its potential health benefits.

Here are some additional tips for taking Omega-3 oil with a fatty meal:
Take the oil at the beginning of the meal, as this allows for better absorption.
Choose a meal that is naturally high in healthy fats.
Avoid taking omega-3 oil with alcohol or caffeine, as these can interfere with absorption.
Of course, it's always best to consult with your healthcare provider for personalized advice regarding the most effective way to take omega-3 supplements for your specific needs.
