I need to let you know one thing I do not typically share publicly.

In 2013, I used to be in Calgary visiting a pal after I was rear-ended in a automobile accident. On the time, I did not assume a lot of it. I used to be shaken however felt okay sufficient to make my approach to the airport. I ended at just a little café contained in the terminal, had some water — after which boarded my flight.

It wasn’t till I used to be someplace over the Rockies that I spotted I had left each single piece of my baggage, and the whole lot in it, sitting in that café.

That second wasn’t a journey distraction. It was the primary signal of one thing extra critical. I used to be recognized with a concussion and with one thing I hadn’t recognized was even potential: short-term visible reminiscence loss.

I could not maintain onto snapshots of photos or textual content. Studying was almost unimaginable. My eye coordination was utterly off. And for the primary time in my life, I skilled a sudden-onset despair — which, I later realized, is a acknowledged consequence of head accidents, and probably the most alarming issues I’ve ever been via.

My mind was injured, infected, and agitated. And the intricate community of neurons, nerves, and the protecting barrier surrounding them was all caught in the identical storm.

What I found throughout that restoration modified how I take into consideration mind well being — for folks and for canines — completely.

DHA: The Basis Your Mind, Nerves, and Their Guardian Are Constructed On

Earlier than I let you know extra, I need to offer you a transparent image of what DHA really does within the physique — as a result of I believe most individuals solely have half the story.

DHA — docosahexaenoic acid — is an omega-3 fatty acid labeled as “important,” which means the physique can not produce significant quantities of it by itself. It should come from the food regimen. And it isn’t merely a nutrient that’s “good for” the mind. It’s, fairly actually, one of many main structural constructing blocks that the mind, the nervous system, and the blood-brain barrier are constructed from.

What DHA Does

Within the mind itself:

DHA makes up roughly 30–40% of all of the fatty acids within the mind’s gray matter. It’s woven into the cell membranes of each neuron — the speaking cells of the mind.

Membrane flexibility, the pace and high quality of sign transmission between neurons, the flexibility of synapses to kind and strengthen — all of those depend upon an enough, constant provide of DHA. With out it, neurons develop into inflexible, communication slows, and the structure of considering, reminiscence, and temper begins to degrade.

Within the blood-brain barrier:

That is the place the story of DHA and mind safety turns into much more exceptional — and the place the blood-brain barrier (BBB) suits as one important half of a bigger image.

The BBB is a extremely selective membrane lining the blood vessels that feed the mind. It decides what will get in and what stays out — vitamins and oxygen in, toxins, pathogens, and inflammatory molecules out. DHA is a core structural fats within the BBB itself.

When DHA is enough, the barrier holds tight and the mind is shielded. When it’s depleted, the barrier weakens — and the mind turns into permeable to issues it was by no means meant to come across.

Within the nerves:

DHA helps kind and keep myelin — the insulating sheath that wraps round nerve fibers and permits electrical alerts to journey shortly and precisely. Consider myelin just like the coating on {an electrical} wire. When it’s wholesome and intact, alerts journey cleanly. When it’s depleted or broken, alerts misfire, decelerate, or do not arrive in any respect.

For this reason DHA deficiency can present up not solely as cognitive fog, however as poor coordination, sensory sensitivity, sluggish reflexes, and emotional dysregulation.

Within the retina:

The best focus of DHA in all the physique is discovered within the photoreceptor cells of the retina.

What the BBB Protects Towards — and Why It Issues

Now that you just perceive DHA’s function all through the entire system, the BBB piece makes much more sense.

When the blood-brain barrier is wholesome and well-nourished with DHA, it:

Helps blocks heavy metals, pesticides, and environmental toxins from reaching mind tissue

Retains out pathogens — micro organism, viruses — that would set off neurological irritation

Filters inflammatory molecules generated elsewhere within the physique, slowing the cascade that results in cognitive getting old

Regulates the exact supply of vitamins and alerts the mind depends on

Protects the fragile neuronal setting that temper, reminiscence, character, and cognition depend upon

When it breaks down — via DHA deficiency, persistent irritation, toxin accumulation, or harm — dangerous substances attain neurons that had been by no means meant to come across them. Mixed with already-depleted neuronal membranes and fraying myelin, that is once you see the complete image of cognitive and neurological decline: reminiscence loss, anxiousness, coordination issues, behavioral adjustments, despair

In my case, the accident had triggered all of it directly — acutely. The despair, the visible reminiscence loss, the lack to learn or observe textual content — these weren’t separate signs. They had been one story: a mind starved of the structural fats it wanted to operate, talk, and shield itself.

What Modified All the things

I attempted many approaches throughout my restoration. But it surely wasn’t till we launched FeelGood Omega – a toxin free squid oil with one of many highest ranges of DHA — that my signs genuinely started to clear.

My visible reminiscence returned. The despair lifted. My skill to navigate textual content got here again. I began to really feel like myself once more.

DHA shouldn’t be a drug. It did not manipulate or suppress my signs in a pharmaceutical sense. What it did was give my neurons, my myelin, my retinal cells, and my blood-brain barrier the structural uncooked materials they wanted to rebuild and calmed the irritation. The physique knew precisely what to do with it. I simply had to offer sufficient of it, persistently, over time.

Why This Issues for Your Canine

Our and our canine’s mind face many ongoing challenges. 

Processed meals, environmental toxins, a food regimen dominated by omega-6 fat (the inflammatory variety) with minimal omega-3, persistent low-grade intestine irritation, and the pure technique of getting old all place regular, ongoing stress on each layer of the system I’ve described — neurons, myelin, the retina, and the BBB.

Sadly, canines consuming business kibble are chronically low in DHA, and even when omega-3s had been added through the kibble’s manufacturing course of, they oxidize and go rancid earlier than they even go in your canine’s bowl.

There is no sudden crash, no dramatic occasion. Only a deterioration of the mind, nerves, and their protecting barrier.

When DHA ranges are maintained, we and canines keep mentally sharp, emotionally balanced, well-coordinated, and cognitively current nicely into their senior years. After they’re not, you begin to see the early indicators: extra sleeping, much less engagement, confusion, anxiousness, poor coordination, boring eyes, behavioral adjustments. Too typically written off as previous age. Too typically, not less than partially, preventable.

And it begins lengthy earlier than the senior years. DHA is crucial throughout childhood and puppyhood — the primary months and years of life is when the mind is rising quickest, laying down its complete foundational structure. The neurons being constructed, the myelin being shaped, the BBB being established — all of it requires a beneficiant, constant provide of DHA. Beginning early and staying constant is at all times the simplest technique.

Why Calamari Oil — Not Fish Oil

Once we developed FeelGood Omega, I spent almost two years discovering the cleanest, most DHA-rich marine oil accessible. The reply was calamari — squid oil.

Calamari oil has roughly double the DHA focus of most fish oils. One teaspoon of FeelGood Omega delivers 920mg of DHA and 410mg of EPA — among the many most potent per-serving ranges accessible anyplace.

Squid sit low on the marine meals chain, which implies far much less bioaccumulation of heavy metals like mercury and lead. This issues enormously — as a result of heavy metals are themselves recognized to compromise the BBB and neurological operate. You can’t shield your canine’s mind with an oil that introduces neurotoxic compounds on the similar time. Each batch of FeelGood Omega is micro-filtered and third-party examined for heavy metals and toxins. That’s non-negotiable for us.

Calamari can be essentially the most sustainable marine omega-3 possibility accessible — squid populations are steady and sturdy. I be ok with giving it to Pax daily, including a double dose in his veggies as a result of he likes them higher that means.

The Intestine–Mind Connection

Another piece value understanding: your canine’s intestine well being immediately impacts the well being of their mind — together with the BBB.

A wholesome, various intestine microbiome produces anti-inflammatory alerts and short-chain fatty acids that assist keep the tight junctions of the BBB from the surface in. When the intestine is infected or “leaky,” inflammatory alerts journey via the bloodstream and weaken the mind’s barrier over time.

For this reason I typically suggest pairing FeelGood Omega with GutSense. These two dietary supplements tackle the identical underlying system from totally different angles — GutSense stabilizes the intestine lining and microbiome, FeelGood Omega supplies the structural DHA for neurons, myelin, and the BBB. Collectively, they create whole-system mind and nervous system safety.

Each day Mind-Safety Habits

Begin early and keep constant. DHA shouldn’t be saved in giant reserves within the physique. It have to be replenished every day. Sporadic supplementation doesn’t give the mind or the physique what it wants.

High quality is as essential as amount. Rancid or low-DHA oil gives little or no and should add oxidative stress. If it smells rancid, it isn’t doing what you hope.

Analysis additionally reveals that providing double and even triple the “every day dose” will increase the advantages. Pax will get double the label dose and I take 3000mg (3g) every day.

Give it time. Neurological adjustments — on the degree of membranes, myelin, and the BBB — take months, not days. Most individuals discover significant shifts in power and engagement inside 4–8 weeks, however the deeper structural work occurs over constant months of every day use.

That is particularly essential if you find yourself addressing an harm, irritation or cognitive signs reminiscent of dementia, Alzheimer’s or Parkinson’s illness.

Do not look ahead to signs. Depletion is gradual, doggy and human dementia are actual and prevention is at all times extra highly effective than intervention. That’s my mantra.

Actually, I did not anticipate a automobile accident in Calgary to develop into probably the most formative experiences of my work and my private well being journey. However typically the troublesome issues educate us essentially the most.

I take FeelGood Omega H+ each single day and I give FeelGood Omega to Pax every day. Not as a result of both of us is unwell — however as a result of there’s a physique of analysis exhibiting, how essential it’s for well being and longevity.

Often Requested Questions (FAQs)

What does omega-3 really do for my canine’s mind?

Omega-3 fatty acids — particularly DHA — are the first structural fats making up your canine’s mind tissue and the blood-brain barrier. Consider DHA because the constructing materials that retains mind cell membranes versatile, communication between neurons sharp, and the protecting barrier across the mind sturdy. With out sufficient DHA, the mind ages quicker, irritation rises, and cognitive operate declines.

What is the distinction between EPA and DHA — do each matter for the mind?

DHA is the first structural omega-3 within the mind — it is actually constructed into the cell membranes of neurons and the blood-brain barrier itself. EPA performs a complementary anti-inflammatory function, lowering the mind irritation that accelerates cognitive getting old. Each matter, however DHA is the one most critically linked to mind construction and the blood-brain barrier particularly. That is why we selected calamari oil, which has an unusually excessive DHA-to-EPA ratio.

Why is calamari/squid oil higher than common fish oil for mind well being?

Calamari oil comprises considerably larger concentrations of DHA in comparison with most fish oils, making it the superior selection for mind and blood-brain barrier assist particularly. It additionally comes from a smaller marine animal decrease on the meals chain, which implies far much less accumulation of heavy metals and toxins — defending the very barrier you are attempting to strengthen. FeelGood Omega is micro-filtered and examined toxin-free for that actual motive. 

How a lot FeelGood Omega ought to I give my canine?

The fundamental dosing is weight-based, take into account 2 – 3x the dose for the best impact of the next label dosage which I do for Pax:

¼ tsp for canines below 22 lbs½ tsp for 23–55 lbs1 tsp for 56–110 lbs1¼ tsp for canines over 110 lbs

When ought to I begin giving omega-3 for mind well being — is it too late for my senior canine?

It’s by no means too late, however beginning early in puppyhood or childhood is at all times higher. DHA is crucial at each life stage — from puppyhood for mind growth, via maturity for upkeep, to the senior years for safeguarding towards cognitive decline. Many guardians discover significant enhancements in senior canines’ alertness and engagement inside weeks of constant supplementation. Consider it as long-term upkeep for the mind, not an emergency repair.

Does omega-3 assist with canine dementia (Canine Cognitive Dysfunction)?

Sure, and there may be stable science behind it. A number of research present canines supplemented with DHA and EPA display improved studying skill, reminiscence, and psychomotor management in comparison with unsupplemented canines. DHA particularly has neuroprotective properties that assist neuron survival and the well being of the blood-brain barrier — the defend that retains dangerous substances out of the mind. Early and constant supplementation is the simplest technique.

What’s the blood-brain barrier, and why does it matter for my canine?

The blood-brain barrier is a extremely selective protecting defend between the bloodstream and the mind. It decides what will get in and what stays out — letting in vitamins like oxygen and DHA whereas blocking toxins, pathogens, and inflammatory molecules. When this barrier is compromised — by poor food regimen, environmental toxins, persistent irritation, or getting old — dangerous substances leak into the mind, accelerating cognitive decline and neurological issues. Holding the BBB sturdy is among the most essential, and below appreciated, acts of affection on your canine’s long-term mind well being.

Can I give the identical omega-3 product to myself and my canine?

Sure. 

How lengthy does it take to note a distinction in my canine’s mind operate?

Many guardians discover adjustments — just a little extra spark, higher sleep, improved engagement — inside 4 to eight weeks of every day supplementation. Significant structural adjustments on the degree of the blood-brain barrier and mind cell membranes take longer, sometimes 3 to six months of constant use. It is a lifetime funding in mind resilience.

Are there any unintended effects of giving omega-3 for mind well being?

FeelGood Omega is extraordinarily nicely tolerated. This complement is protected for long-term every day use.

What’s the MFSD2A transporter — how does DHA really get into the mind?

The blood-brain barrier doesn’t simply let vitamins in freely — it has “bouncers.” For DHA, the bouncer is a protein known as MFSD2A, a devoted transporter that bodily carries DHA molecules throughout the barrier and into the mind. Analysis reveals that with out this protein, mind DHA ranges drop by 80–90%, and animals develop neuronal loss and cognitive deficits.

How does intestine well being connect with the blood-brain barrier in canines?

This is among the most enjoyable frontiers in canine well being, and it connects two of the pillars in Dr. Dobias’s method — intestine assist and omega-3. A wholesome intestine microbiome produces short-chain fatty acids that sign the BBB to remain tight and intact. When the intestine is infected or “leaky,” that irritation can journey via the bloodstream and weaken the BBB from the surface in. For this reason combining GutSense and FeelGood Omega is such a strong technique — you’re defending the mind from each ends.

Can omega-3 assist with canine anxiousness and behavioral points, not simply reminiscence?

Generally. The blood-brain barrier and its integrity are immediately linked to emotional regulation — when the BBB is compromised and irritation reaches the mind, it impacts temper, stress response, and worry processing, not simply reminiscence. DHA and EPA each assist the anti-inflammatory pathways that assist hold emotional reactivity in test. Many guardians supplementing for bodily well being discover calmer, extra relaxed canines as a secondary profit.

Ought to I give omega-3 to a pet to assist mind growth?

Sure, and this is among the most essential home windows. The primary yr of life is when the mind is rising quickest and laying down its foundational structure — and DHA is the first constructing block. Omega-3 is related at each life stage, however the pet interval is arguably the highest-priority time to make sure constant, enough DHA consumption. Beginning FeelGood Omega from early puppyhood helps construct a mind that’s wired for resilience from the beginning.

Can omega-3 assist canines recovering from neurological harm, seizures, or stroke?

Normal analysis suggests DHA has neuroprotective and anti inflammatory properties that will assist restoration following neurological occasions, together with lowering injury-related irritation within the mind. Nevertheless, in any scenario involving seizures, stroke, or acute neurological circumstances, we strongly suggest working intently with a veterinarian earlier than adjusting supplementation.

Does heavy metallic or toxin publicity harm the blood-brain barrier in canines?

This is a vital, and considerably under-explored connection. Toxins and heavy metals within the setting and meals provide can compromise the integrity of the BBB, making it “leaky” and permitting dangerous substances into the mind. That is precisely why Dr. Dobias recommends each supporting detox pathways (LiverTune) and actively rebuilding the BBB via constant DHA consumption (FeelGood Omega). A clear liver reduces the poisonous load within the blood; DHA strengthens the barrier that protects the mind from what stays. 

Is algae-based DHA simply pretty much as good as calamari oil for my canine’s mind? 

Algae oil is the place fish and squid get their DHA within the first place — algae is the unique supply. Nevertheless, most commercially accessible algae oils for pets are considerably decrease in DHA focus than calamari oil, which means you would want to offer extra to attain the identical brain-supporting dose. FeelGood Omega is micro-filtered calamari oil with confirmed EPA (≥410mg) and DHA (≥920mg) per teaspoon, examined toxin-free — a troublesome benchmark to match within the algae oil market.

My senior canine sleeps all day — might low omega-3 be a part of the explanation?

It could possibly be a contributing issue. Lethargy, diminished engagement, and extreme sleeping are among the many early indicators of canine cognitive dysfunction — and DHA deficiency is a acknowledged think about cognitive decline. Quite than instantly attributing it to “previous age,” it’s value supporting the mind with constant, high-DHA omega-3 and monitoring for adjustments over 4–8 weeks. That mentioned, sudden adjustments in power or sleep ought to at all times be evaluated by a vet to rule out different causes.

Is omega-3 protected to offer alongside medicines like Apoquel or NSAIDs?

Normal steering is that omega-3 is taken into account very protected and should actually cut back the wanted dose of anti-inflammatory medicines over time. Some sources recommend that high-dose omega-3 can might have gentle blood-thinning properties. Nevertheless, we’ve not seen this in follow and take into account customary upkeep doses protected.

Can omega-3 cut back seizure frequency in canines?

Whereas we won’t make particular claims about seizure administration, omega-3 fatty acids are recognized to have neuro-protective and anti inflammatory results within the mind, and a few early human analysis suggests they could assist neurological stability. For canines with a seizure historical past, we strongly suggest utilizing larger doses omega-3 as part of a complete remedy plan.
