Omega-3’s and a Boy in a Coma
Omega-3s have been used in humans to treat traumatic brain injury. One such study in the American Journal of Emergency Medicine presents a case study about a teenager who suffered a severe TBI in 2010.
Like me, he was diagnosed with a diffuse axonal injury with an initial Glasgow Coma Score of 3, which is the lowest possible score (no response to any stimuli, but still alive).
Thought to be in a permanent vegetative state, he was given a gastric tube (PEG), and a procedure was performed, which left him breathing through a tube protruding from his neck (tracheotomy).
Then The Fish Oil Came…
Ten days after the injury, he was given a large dose (15 ml, which is about 13 g) twice a day (30 mL/day) of Nordic Natural UltimateOmega via his PEG (feeding tube).
On the 21st day, he was weaned off of the ventilator and soon progressed from a vegetative state to attending his high school graduation three months later!
What About the Risk of Blood Thinning?
Many Clinicians are afraid to use high-dose omega-3s because of their blood thinning effects. This paper addresses this concern and shows much evidence to support the use of high-dose fish oils as a treatment for brain injury:
Omega-3 Fatty Acids as a Putative Treatment for Traumatic Brain Injury
Hasadsri, L., Wang, B. H., Lee, J. V., Erdman, J. W., Llano, D. A., Barbey, A. K., . . . Wang, H. (. (2013). Omega-3 Fatty Acids as a Putative Treatment for Traumatic Brain Injury. Journal of Neurotrauma, 30(11), 897-906. doi:10.1089/neu.2012.2672
“…Potential harmful effects of n-3 PUFAs [omega-3s], however, have been described in the literature. Due to the established anti-thrombotic action of these compounds, for instance, they may increase the risk of hemorrhagic stroke, as suggested by a necropsy-based study of four cases in Greenland.138 The authors warn, however, that the power of their analysis is weak given the limited sample size, and that their study may have been subject to inadvertent selection bias.138 In addition, multiple clinical trials have shown that highdose fish oil consumption is safe, even in patients receiving other agents that may increase the risk of bleeding, such as aspirin and warfarin.139–141 The overall clinical data suggests that DHA at doses up to 6 g/day does not have deleterious effects on platelet aggregation or other clotting parameters in normal individuals, and fish oil does not augment aspirin-induced inhibition of blood clotting.137 Platelet function is, on the other hand, inhibited by DHA consumption in type 2 diabetics, but it is suggested that this may actually be of benefit to these individuals, especially when coupled with the other activities of DHA.142 Nevertheless, it may be prudent to discontinue high-dose supplementation in the setting of an acute bleeding illness or in patients at high risk for hemorrhagic stroke or, as is frequently recommended with aspirin, warfarin, and clopidogrel, prior to planned invasive procedures with the highest risk for bleeding complications.143–146″
TLDR: Summary of the above article
In other words, while Omega-3’s have been shown to thin the blood, this was mainly shown by a study that the authors admit is somewhat weak because of a small sample size and selection bias.
Several other studies have shown high-dose fish oil consumption to be safe, even in patients who are receiving other blood thinners like warfarin and aspirin.
And up to 6g/day of DHA does not cause harm on clotting parameters in normal individuals, nor does it change aspirin-induced inhibition of blood clotting.
From the Abstract of this paper: Lien EL. (2009). Toxicology and safety of DHA. Prostaglandins Leukot Essent Fatty Acids 81, 125–132.
“DHA supplementation studies in adults have employed doses ranging from less than 1 to 7.5g/d, and have not resulted in any consistent adverse responses in platelet function, lipid levels, in vivo oxidation parameters, glycemic control, or immune function.”137
Liquid Omega-3’s and Traumatic Brain Injury Treatment
This article is about how to use liquid omega-3’s as an adjunct therapy to help with brain injury, and other cases of severe brain inflammation. Moderating inflammation and oxidative stress in the brain after a traumatic brain injury or an ischemic injury like stroke is critical. Omega-3’s are a low-risk therapy that can help thousands of veterans and civilians alike.
A Case for Using Liquid Omega-3’s
High-dose N-Acetyl-Cysteine (NAC) is used in hospitals when someone may have overdosed on Tylenol because it has been found that NAC cleans out a liver that an overdose has burdened. Large quantities of research back this use of NAC in the treatment of Tylenol overdose.
Omega-3s have a similar record in regard to anti-inflammatory effects and reduction in oxidative stress in the body.
Liquid Omega-3’s helped JJ Virgin’s son recover from a traumatic brain injury. A little oxidative stress in the brain is a good thing, but prolonged oxidative stress can lead to cell death or apoptosis.

Omega-3’s Can Reduce Brain Injury Severity
After finding very favorable results in a study testing the use of DHA after a severe traumatic brain injury (diffuse axonal injury) in rats (CITE), the West Virginia University School of Medicine conducted a follow-up study to see the effect of DHA supplementation before a brain injury.
The study found that rats who were supplemented with DHA before a brain injury showed less damage done to the brain after, as well as better brain function, as assessed by maze testing. (CITE)
Using Liquid Omega-3’s in Gastric Feed
Supplementation and whole food sources may be the most effective way to deliver this vital nutrient to patients with a gastric feed.
When feeding through a gastric tube, blend fatty fish and liquid Nordic Natural UltimateOmega in a blender to create a nutrient-dense feed.
For vegans and vegetarians, we can blend Nordic Naturals – Algae Omega for a good source of EPA and DHA. (left)
Because cod liver oil is rich in many other fat-soluble vitamins, such as vitamin A, cod liver oil may not be appropriate at therapeutic (very high) doses.
Fat-soluble vitamin A is great, but at high doses, it can cause hypervitaminosis. As always, work with a qualified practitioner when supplementing, and share this information with your doctor to help us shift this paradigm in medicine.

Docosahexaenoic Acid (DHA) for Synaptogenesis
DHA is a kind of Omega-3 fatty acid that is largely found in fatty fish like mackerel, sardines, salmon, and tuna. As shown above, there are studies showing the use of Omega-3s in the waking of comatose patients.
Because it seems to have an extremely potent effect on neurological recovery and in protecting the brain, not only are sports leagues very interested in Omega- 3s and their effects in preventing and treating brain injury, but scientists in the military are also inspecting this nutrient for brain injury treatment and neuroprotection.
In 2011, an article in Military Medicine, the official journal of The Association of Military Surgeons of the United States (AMUS), wrote that “a comprehensive, coordinated research program to evaluate the multiple uses of n-3 FA [Omega-3 fatty acids] should be a high priority for the Department of Defense.“ (CITE)

Adding Omega-3s to Your Supplement Regimen:
While therapeutic (very high) doses of Omega-3s can be beneficial in the short term, I do not think that large doses of Omega-3s should be an ongoing practice.
In addition to eating plenty of cold water fatty fish, I still supplement with Omega-3s, but I prefer to do so in reasonable amounts (no more than 5g/day). Once you get over a deficiency, you can dial the dosage back a bit.
My Omega-3 supplement regimen is 2.5 to 5g or 1 to 2 capsules of my Protect & Restore High DHA Omega-3s.
For a vegetarian source, Nordic Naturals – Algae Omega can be supplemented. Check with your qualified healthcare practitioner for amounts specific to you or your loved one.
