Omega 3 Supplements (Part 2)

We continue our series of questions reviewing the benefits of Omega-3 fish oils with Drs. Wilson and McGinty (part one available here).

4. Can I not just eat more fish and not use supplements?

"YES!!!!!!! is the short answer. You would need to eat approximately 3.5oz of fish every day to acquire the desired daily amount of Omega 3 oil. You also need to remember that this figure can vary due to things like the variety of fish you choose or how it's prepared." Dr. Wilson answers, "As with most things fish is much healthier baked or broiled. Deep­ frying may just undo all the good work you're trying to do."

He goes on to add, "With supplements you have the really big advantage of consistency - you can know that you are consistent with your doctor recommended dosing regime.  Another advantage of using a supplement for Omega 3 is all reputable manufacturers screen their product for unwanted elements, like mercury, thus reducing the health risks associated with these heavy metals.  The supplements also make it easier to add in to a busy lifestyle, whereas switching to a fish rich diet may mean a major change for some."

5. So if I'm going to start taking these supplements, is there an omega 3 fish oil that is better quality?

"That's a really interesting question," Dr. McGinty responds, "To answer this it really is best to look at the kinds of fish oil supplements available, there two different kinds:

a) Triglyceride or TG and

b) Ethyl Ester or EE

TG is naturally occurring and the EE is synthesized chemically. Putting it another way. EE omega 3 is like having fruit juice made from concentrate and I for one prefer my juice freshly squeezed. TG
for me then!"

"Great point!" Dr. Wilson adds to the explanation, "There has been various studies into the comparison between the two forms and the long and short is that the EE is not absorbed nearly as effectively as the TG. Some studies showing an absorption rate up to 50 times slower for the EE derivative. Strike 2 for EE!"

"Looking into it further, there's also some debate about the harm that could come from the metabolism of the EE type in the intestines. During it's synthesis the EE form has a single fatty acid molecule bonded to an ethanol “backbone” whereas the naturally occurring TG has 3 fatty acid molecules bonded to a glycerol “backbone”. The ethanol is released when broken down in the gut and this for many is a cause for concern. That said, tests have shown that the amounts of ethanol (an alcohol) should be safe for humans. Not quite strike 3 but that bonding to the ethanol “backbone” also means technically that the EE form isn't a true oil.

That's a home run for TG in my game!"

6. Can I not just take omega 3,6 and 9 combined?

Dr. Wilson is enthusiastic to answer this question, "Firstly Omega 3 and 6 are essential acids and need to be consumed in our basic human diet through food sources or supplements. Omega 9 is non-­essential and as such isn't actually required so why supplement it at all.

Omega 3 has a potent anti­-inflammatory response in the body. This helps reduce the pain and swelling from most inflammatory responses in the body whereas Omega 6 has the complete polar opposite being pro-­inflammatory. Maintaining a balance between these two important acids is critical. The kicker is that Omega 6 is abundant in the Western diet so you're much less likely to need a supplement.

So, yes, you could take an Omega 3, 6 and 9 supplement but in the words of my esteemed business partner, Dr. Euan McGinty, “You can but you'd be wrong!”

In conclusion, I believe supplementation of Omega 3 fish oil in the Western diet is essential, but, as with many things, the simple rule is everything in moderation. Obtaining it in it's most natural form is always preferred and regularity works best. Always check with your doctor before starting any new medication or supplements.

Many thanks to optometrists Dr. John Wilson and Dr. Euan McGinty for taking the time to answer these questions.

Omega 3 Supplements (Part 1)

Here at Ocean, Dr's Wilson and McGinty are strong advocates of the use of Omega-3 fish oil for the health of your eyes, especially when a patient has dry eyes.  We decided to interview our optometrists to find out more and answer some of the common questions that you may have about Omega-3 fish oils and the eyes.

1. Why Omega-3 fish oil? Won't flax seed or hemp oil do?

"There are 3 acids that make a complete omega 3 molecule. These are ALA, DHA and EPA.  ALA is found mainly in nuts and plants, e.g. walnuts and flax seed, but to a lesser degree in fish.  DHA and EPA are found to be more concentrated in fish derived Omega 3."  Dr. Wilson explains.

"Until recently, this wasn't considered an issue as all Omega-3 was really considered equally beneficial. More recently, however,  studies have found that the processing of ALA in the human body isn't nearly as efficient. It's conversion to the more usable DHA derivative is limited and slow."

"Now, I'm not saying there are no benefits to the ALA form."  Dr. Wilson adds, "It's still beneficial as a supplement for vegans and vegetarians who may wish not to take the fish oil, but you need to consume approximately 80% more than the equivalent fish oil supplement to achieve the same effect."

2. When should I take my fish oil?

Dr. McGinty responded, "Conventional reasoning states that Omega-3 supplementation should take place with meals, or just prior to meals. Probably to help combat the fishy aftertaste that is sometimes encountered by some and also to promote good uptake through digestion. It is also wise not to take fish oil prior to working­ out as this may cause gastrict distress."  

"Did you know that I used to have really trouble with taking them?" Dr. Wilson asks, "Then I was chatting about them with a retired pharmacist who said “Why don't you just freeze them and take them at night before bed?” I was amazed that this worked so quite often will recommend this to my patients and so far no-­one has complained of any gastric­ distress through the night"

"I had never heard of that" remarked a surprised Dr. McGinty, "every day's a school day!"

"Indeed!  I would value your feed­back if anyone tries it (good or bad I'm interested) so if you do try this tip, please e-mail me with how you get on: dr.john@oceanoptometry.ca."

3. How much fish oil should I take?

"Now, as optometrists we are dealing with the eyes primarily, but have to remember that the eyes are connected to the rest of the body and therefore have to consider any potential side ­effects." explains Dr. Wilson, "I never recommend more than the daily recommended amount of Omega-3 fish oil, which is between 900-­1200mg/day. This amount should contain a minimum of 600mg of DHA so check those labels carefully."

Dr. McGinty adds, "Sometimes you actually have to take 2-­3 times the amount of “oil” to get the appropriate concentrations depending on the quality and type of fish oil you choose. 

There are also times that amounts higher than this that may be recommended by your Physician for other health issues, especially increased blood triglycerides, but this is done in careful consideration of any other medications you're taking at the time. Omega-3 acids can both enhance and decrease the effectiveness of a number of medications."

"Absolutely" agrees Dr. Wilson, "There is even evidence that excessive amounts of Omega-3 can, in some people, increase their risk of stroke. I, for one, believe in everything in moderation so the daily recommended amount values sit well within my ethics and personal feelings."
