7 Things Vegetarians and Vegans Should Know about their DHA and EPA Source The vegetarian diet largely depends upon ALA to be synthesized into EPA and DHA in the body, according to how omega-3s are metabolized, handled by the inherent systems in the body. Important findings now show that ALA conversion into EPA and DHA is rate limiting. The first metabolic step in EPA synthesis by the enzyme delta-6 desaturase is kinetically slow, so most ALA undergoes oxidative metabolism for energy and is not converted to EPA. That is, omega-3 oil supplementation from plant sources may produce only 7% of the EPA levels otherwise gained through fish oil supplementation. DHA accumulation from ALA only occurs at trace levels due to the additional steps required to convert EPA into DHA. In contrast, dietary DHA supplementation will result in steady state DHA concentrations and modest increases in EPA concentrations through DHA retro-conversion, producing EPA at 5-11% of accumulated DHA levels. With continuous supplementation, EPA/DHA levels plateau, suggesting the body first needs to incorporate omega-3s directly through the diet before limiting omega-3 fatty acid accumulations by oxidative metabolism.
Pure One™ is derived from microalgae, one of the most DHA-rich forms of Omega-3 oil available. Other plant-based sources of Omega-3s (flax seed, canola oil or walnuts) don't contain either DHA or EPA. Instead, they contain ALA, an Omega-3 precursor that requires the body to go through a three step process to convert to DHA and EPA. That conversion process makes ALA much less effective and efficient in gaining the needed fatty acids. It makes the body work harder and ends up providing much less DHA or EPA. Omega-3 microalgae oil provides DHA and EPA directly.
Also, our product is made with purely vegetarian AL-GTM (carrageenan) capsules - the latest in natural encapsulation technology.
Our Omega-3 oil is grown and refined in state-of-the-art (cGMP certified) quality controlled facilities in the United States. Since 1997, FDA experts have granted our Omega-3 oil and our grower with a Generally Regarded as Safe designation for foo d supplements.
Finally, we use only conventional growing techniques. While the Omega-3 for Pure One™ is grown in a safe, clean, controlled environment, it is also grown naturally without any genetic modification. See our diagram on the conversion process of ALA.
With few ALA rich plant sources for vegetarians, omega-3 supplements are an important consideration. Beyond flax, walnut and mustard seed oils, ALA supplementation is limited because stearidonic acid (STA) is poorly formed as the second product in the DHA synthesis pathway. Bypassing delta-6 desaturase at the first step with STA supplementation allows for some EPA accumulation but little DHA omega-3. Plant sources of STA Omega-3 are found most abundantly in the invasive plant species Echium and seldom used herb Borage, now available on the market for vegetarians and vegans seeking omega-3.
Indian mustard seeds contain 1-4% ALA omega-3 (~200 mg/tablespoon). Yet mustard oil supplementation does not produce significant effects compared to DHA omega-3s [31, 32]. Also, as a food it is not clear what effects pre-roasting or heating of mustard seeds have on ALA stability. As with all unsaturated fats, heating and cooking causes a percentage of the fat to undergo air oxidation. Polyunsaturated fats such as omega-3s and omega-6s are particularly sensitive to oxidation and must be consumed in relatively fresh foods. This suggests conversion of ALA to longer chain omega-3s may be further limited by oxidation of available omega-3 precursors in pre-cooked and/or processed foods.
Proper information is particularly important as awareness of the benefits of omega-3 fatty acids increases. Because DHA is not readily produced from ALA omega-3s, other truly alternative vegetarian sources of DHA are needed. At present, direct EPA/DHA delivery is believed dependent on certain marine fish species, but many fear this may not be a 100% pure or sustainable resource. Reputable data suggest wild marine fish populations are already becoming depleted.
Oils and seeds are not the only omega 3 foods from non-animal sources. One of the best omega 3 sources for everyone is from golden microalgae oil supplements. Not all vegetarian products offer vegetarian capsules, so vegetarians need to watch labels.
Different omega-3 sources vary significantly in the actual omega 3 benefits your body receives. One of the highest valued vegetarian sources of omega 3 is microalgae oil, which your body can use directly for getting DHA and EPA in the right amounts. Microalgae oil gives you the maximum benefit of omega 3s bacause the natural and proper balance of DHA and EPA make it a far superior source, even if you are not a vegetarian or vegan. That means you don't need animal products any more for omega-3s.
While foods and oils like flax oil, walnuts and mustard seeds are sources of vegetarian omega 3, microalgae oil supplements offer a higher standard of benefits, allowing everyone to enjoy omega 3 benefits for healthier lifestyles, regardless of culinary affiliations.
