What's Rhonda Patrick's guidance on omega-3 supplementation?

Rhonda Patrick advises that to achieve an omega-3 index of around 8%, which is associated with a five-year increase in life expectancy, one should supplement with at least 2 grams per day. It may be slightly less for triglyceride form supplements. Most Americans not consuming fish regularly or supplementing would likely have an omega-3 index of around 4-5%. It's important to note that the omega-3 index reflects the percentage of omega-3s in one's blood and is measured using red blood cells, which have a turnover rate of 120 days, so testing for an accurate index should consider this time frame 1.

For choosing fish oil supplements, high-quality ones in triglyceride form are more bioavailable, and it's advised to take supplements with food for better absorption, especially if they are ethyl ester forms. Prescription omega-3 supplements like Vascepa (purified EPA) are prescribed in 4 gram per day dosages 2 3.

Moreover, omega-3 supplements can benefit mental health, potentially reducing the need for or dosage of antidepressant medication, and providing mood benefits 4 5. It's crucial for consumers to look for third-party testing for the concentration of omega-3 fatty acids in supplements, as well as for contaminants and oxidation levels. Dr. Rhonda Patrick personally takes 4 grams daily, split between EPA in the morning and DHA in the evening 2 6.

Lastly, plant-based sources such as certain algae can also provide omega-3s, and it's assumed that if someone's budget is limited, and they cannot afford a more general foundational supplement, a high-quality fish oil supplement can be a cost-effective alternative 4.

Rhonda Patrick does not provide specific recommended values for EPA and DHA, but she discusses the importance and benefits of EPA and DHA from omega-3 fatty acids, and how they can be obtained from various supplements and dietary sources. She also mentions that prescription omega-3 supplements like Lavaza, which is a mixture of DHA and EPA, are prescribed in 4 gram per day dosages 1. Additionally, she acknowledges the benefits of 2 to 4 grams per day of EPA from supplementation for mental health and mood improvement 2.

It is advised that when choosing fish oil supplements, one should consider their form (triglyceride vs. ethyl ester), as well as look for third-party testing for accurate omega-3 fatty acid concentrations, contaminants, and oxidation levels 3. For someone not eating fish regularly, omega-3 fatty acids can be obtained from microalgae oil supplements, which is also a viable option for vegetarians and vegans 4.

Dr. Rhonda also shares that she personally takes 4 grams of fish oil per day—2 grams of EPA in the morning and 2 grams of DHA in the evening 5. However, she does not specify that this is a recommendation for others, as individual needs may vary.

Please consult with a healthcare provider before starting any new supplement regimen to determine the appropriate dosage for your individual health needs and goals.

Rhonda Patrick does not seem to provide a specific reason for taking EPA in the morning and DHA in the evening in the provided data. In the Huberman Lab Podcast #70, she notes that she takes 4 grams of fish oil per day—2 grams of EPA in the morning and 2 grams of DHA in the evening. Rhonda states that she happens to get a certain fish oil supplement that separates them, this seems to be a matter of personal preference or convenience rather than a specific rationale based on timing or physiology 1.

For more specific information on the mechanisms of omega-3 fatty acids and their impact on the body and brain, further research into her statements or scientific literature might be required. However, based on the retrieved data, there isn't a citation providing a detailed explanation as to why she takes these fatty acids at different times of day.

Rhonda Patrick advocates for marine sources of omega-3 fatty acids, particularly EPA and DHA, which are found in cold-water fatty fish. Some examples include salmon and fish eggs (roe or caviar), which are rich sources of phospholipid DHA, especially beneficial during fetal brain development 1 2 3. She also discusses differences between fish oil and krill oil supplements, with krill mostly providing phospholipid form of DHA and EPA, which is bioavailable but potentially allergenic for those with shellfish allergies 4.

For vegetarian or vegan individuals, or those seeking plant-based sources, she recommends microalgae oil supplementation as it provides DHA directly, avoiding the inefficient conversion from plant-based alpha-linolenic acid (ALA) to EPA and DHA 5. Additionally, Dr. Patrick notes that while grass-fed meat might have higher levels of ALA, which can convert to EPA and DHA, this process is not very efficient and highly dependent on genetics 5.

Regarding over-the-counter fish oil and concerns about mercury or other contaminants in fish sources, she suggests looking for third-party analyzed brands to ensure quality, emphasizing the importance of choosing the right form of fish oil supplement for proper absorption, such as the triglyceride form 6.
