About Omega-3 Fatty Acids

Omega-3 fatty acids, also known as polyunsaturated fatty acids (PUFAs), are essential fatty acids that are implicated in several bodily functions. However, the body cannot make these fatty acids, making it necessary to get the required amounts from food (e.g. fatty fish) or supplementation. Omega-3 fatty acids can be found in fish, such as salmon, cod, tuna, and halibut, other seafood including algae and krill, some plants, and nut oils.

Although Omega-3 fatty acids play a crucial role in supporting cardiovascular and joint health, they are also extremely important for brain function as well as normal growth and development.

The importance of DHA Omega-3 Fatty Acids

The most significant Omega-3 fatty acids are EPA and DHA and they are both found in differing ratios in most commercially available fish oil supplements. Even those products marketed as high EPA or high DHA supplements contain small amounts of the other fatty acids for more comprehensive protection. DHA is short for Docosahexaenoic Acid and is an Omega-3 fatty acid that is primarily found in the human brain, cerebral cortex, skin, and retina. Although the body can synthesize small amounts of DHA from Alpha-Linolenic Acid (ALA), supplementation is usually recommended to meet the body's requirement of DHA.

Balancing the EPA to DHA Ratio

Conventional wisdom suggests that a high EPA product is better for heart health because EPA can help support the body's natural inflammation response at the cellular levels, but that it likely does not have significant benefits with respect to brain health because it gets rapidly oxidized in the brain. This is, however, not entirely accurate. EPA can help support the body's efforts to combat neurological inflammation by competing for access to the same enzymes that Arachidonic Acid (AA) needs to produce inflammation; in this way, it offers some neurological protection as well.

DHA, on the other hand, is much more beneficial for maintaining brain health because of its spatial characteristics and its ability to maintain membrane fluidity. In addition, the greater spatial attributes of DHA is thought to increase the size of low-density lipoproteins, which inhibits their entry into the muscle cells of the artery; this offers cardiovascular benefits.

However, neither of these traditional lines of thought about EPA and DHA benefits is useful when making a decision about an Omega-3 supplement that contains both EPA and DHA. A better way to think about EPA and DHA is that they each offer benefits that the other does not, but they also offer some synergistic benefits that can only be attained by taking a supplement that contains them both in therapeutic amounts.

Individuals primarily interested in an Omega-3 supplement to support the body's ability to manage cellular inflammation (whether in the heart, brain, or elsewhere), will most likely benefit from a high EPA product, possibly one that has a 3:1 ratio of EPA to DHA. Those interested in an Omega-3 supplement to support membrane fluidity (significant for brain and eye health) and protect the heart from low-density lipoproteins, which are implicated in the development of heart disease should consider a product that has a 3:1 (or higher) DHA to EPA ratio.

DHA Sources: Fish versus Algae

Most commercially available Omega-3 supplements feature DHA primarily from fish sources, but algal sources of DHA have started to gain favor among vegans / vegetarians and individuals with a sensitive GI tract who are prone to fishy reflux. The problem with an algal DHA source, however, is the use of Hexane, a toxic Class 2 solvent that can cause nausea, vertigo, bronchial irritation, intestinal irritation and other effects on the central nervous system, to extract the DHA from the algae. Safer and purer alternatives for a vegan / vegetarian source of DHA include plant-based Omega-3s (e.g. Perilla, Chia, Flax) that contain ALA, which the body uses to synthesize the required amounts of EPA and DHA.

Frequently Asked Questions about Omega-3 Fatty Acids and DHA Gold

What are Omega-3 Fatty Acids?
Omega-3 fatty acids are essential fatty acids because they perform a number of essential functions in the body. Also known as polyunsaturated fatty acids (PUFAs), Omega-3 fatty acids play an important role in supporting heart, joint, and cognitive health.

What is the recommended dosage of Omega-3 fatty acids?
The typical American diet is rich in Omega-6 fatty acids and low in Omega-3 fatty acids, making supplementation necessary. Depending on the reason for taking a fish oil supplement, recommended dosages can range from 500 mg to 3000 mg (3g). If you have or suspect a medical condition, please talk to your doctor before starting any kind of supplementation.

What is the recommended ratio of DHA to EPA in an Omega-3 supplement?
There is little consensus even among experts on what the ideal ratio of EPA to DHA is for optimal overall wellness. However, based on the structure and therapeutic action of EPA and DHA and their purported benefits, we recommend that individuals primarily interested in an Omega-3 supplement to support the body's ability to manage cellular inflammation (whether in the heart, brain, or elsewhere) take a high EPA product, possibly one that has a 3:1 ratio of EPA to DHA. Those interested in an Omega-3 supplement to support membrane fluidity (significant for brain and eye health) and protect the heart from low-density lipoproteins, which are implicated in the development of heart disease may, however, benefit from a product that has a 3:1 (or higher) DHA to EPA ratio.

Does the fish source matter when deciding which fish oil supplement to take?
The American Heart Association recommends dietary intake of oily fish because they are naturally rich in Omega-3 fatty acids and individuals have to consume smaller amounts to meet the recommended intake of EPA+DHA fatty acids. This should not, however, be interpreted to mean that Omega-3 fatty acids from other sources of fish cannot be just as effective in helping to maintain healthy cardiovascular function. All things considered, there are virtually no differences in the structure or function of EPA/DHA Omega-3 fatty acids in fish oil supplements, regardless of whether the Omega-3 fatty acids come from oily fish like sardines or cold water fish like Alaskan Pollock that are used in our DHA Gold product. Because Pollock may not be naturally high in Omega-3 fatty acids like sardines and mackerel, it is possible that ounce for ounce, individuals may have to eat more pollock/cod than sardines or mackerels to get the recommended amount of EPA/DHA, which is not always feasible.

In other words, when it comes to fish oil supplements, most of which are standardized to a certain amount of the same EPA/DHA fatty acids, the species of fish used to source the Omega-3 fatty acids is not nearly as significant as the purity and sustainability of the fish species. To put it in perspective, vegans/vegetarians or individuals who experience side effects from fish oil supplements take plant sources of Omega-3 (Flax, Chia) to meet the recommended daily intake, something the AHA strongly recommends to minimize the risk of nutritional deficiencies. So, in considering which fish oil supplement to buy, purity, potency, and sustainability are far more important and relevant concerns than the species of fish that the oil is sourced from.

Is DHA Gold safe for long-term use?
When taken as directed and in conjunction with a sensible diet and exercise program, DHA Gold is generally recognized as safe (GRAS). However, caution is always advised in individuals who have or suspect a medical condition.

What are the contraindications for DHA Gold?
Please consult a healthcare provider before taking Omega-3 supplements if you are pregnant, breastfeeding, or currently taking any OTC or prescription medications for a health condition. Individuals with a known or suspected allergy to fish and/or other ingredients in the fish oil supplement should find alternative ways to supplement their diets with DHA.

Does DHA Gold interact with any prescription medications?
Because fish oil may increase fasting blood glucose levels, diabetic individuals currently taking or planning to take diabetic medications should take fish oil only under the supervision of their healthcare provider. Fish oil may also interact with supplements and medications that lower blood pressure, block the absorption of fats, and birth control pills. As a general rule, please do not self-diagnose, self-treat, or self-medicate, if you know or suspect a medical condition.
