Why Most Nutrients Never Reach Your Dog's Brain

Why Most Nutrients Never Reach Your Dog's Brain

Your dog's brain is protected by the blood brain barrier, which blocks most nutrients, including common antioxidants and glutathione itself. Alpha lipoic acid is one of the few antioxidants that crosses it, and once inside it helps recycle vitamins C and E so they last longer.

Key Takeaways

  • The blood brain barrier decides what reaches the brain and turns most of it away.
  • Glutathione is the brain's main antioxidant defense, and it cannot cross the barrier.
  • Alpha lipoic acid has a structure that lets it cross.
  • Once inside, ALA recycles antioxidants already there instead of being used up.
  • A short walk after a supplement increases blood flow and nutrient delivery.

We all want to do right by our dogs. We research the best foods, we look for the cleanest ingredients, and we would do just about anything to help them stay healthy and sharp.

So it hit hard to learn that most of the good nutrition we give our dogs never actually reaches the one organ that needs it most. Their brain.

The security system in your dog's brain

Your dog's brain has a built in security system called the blood brain barrier. It lines every blood vessel in the brain and decides what gets in and what gets turned away.

It does a great job keeping dangerous things out, like toxins and bacteria. It also blocks many of the beneficial nutrients we feed our dogs, including most common antioxidants.

You could be giving your dog the best nutrition available and their brain might barely get any of it.

The defense that runs out

Every day, your dog's brain is attacked by free radicals and, left unchecked, they wear down brain cells over time.

The brain's main line of defense is an antioxidant called glutathione. When glutathione levels are healthy, the brain can maintain itself. When they drop, brain cells become more vulnerable to that daily wear and tear.

The obvious answer would be to give more glutathione. Like most nutrients, glutathione itself gets blocked by the barrier.

The antioxidant that gets through

That is where alpha lipoic acid comes in. ALA has a unique molecular structure that allows it to cross the blood brain barrier. It is one of the very few antioxidants that can.

Once inside, it helps recycle other antioxidants already in the brain, like vitamins C and E, so they last longer instead of being used up and lost.

We included ALA in NeuroChew because it can actually reach the brain and support its natural defenses from the inside better than almost any other antioxidant.

What most supplements miss

Most dog supplements do not think about this. They load up on antioxidants that never make it past the barrier. The label looks great but the brain never sees the benefit.

If you are giving your dog any kind of supplement, pairing it with a short walk or active play afterward can help. Physical activity increases blood flow, which helps deliver nutrients more efficiently throughout the body.

Our dogs deserve better than a label that looks good. A healthy, happy dog is one delicious chew away.

Frequently asked questions

What is the blood brain barrier?

A lining in the blood vessels of the brain that controls what passes into brain tissue. It keeps toxins and bacteria out, and it also blocks many beneficial nutrients.

Why can't dogs just take glutathione?

Glutathione is the brain's main antioxidant defense, but supplemental glutathione is blocked by the barrier, so it does not reach the brain in a useful way.

What is alpha lipoic acid?

An antioxidant with a molecular structure that allows it to cross the blood brain barrier, where it helps recycle vitamins C and E so they last longer.

Is alpha lipoic acid safe for dogs?

It is used in canine supplements at controlled amounts. Dosing matters, so follow the label and ask your veterinarian if your dog takes medication.

Does exercise help nutrient delivery?

A short walk or active play after a supplement increases blood flow, which supports delivery of nutrients through the body.

At Furever Active, our journey began with a deep, unwavering love for our four-legged companions.

For over a decade, we've been touched (inspired) by the countless ways dogs have brought joy, comfort, and love into our lives. Whether it's a wag of the tail, a gentle nuzzle, or the simple act of being there when we needed it most, dogs have an extraordinary way of saving us, just as much as we save them.

We're a small, family and friend owned company founded on the belief that every dog deserves to age gracefully, with the same vitality and mental clarity we want for all of our family members. Our premium, fresh-made supplements are crafted with love, using only the highest quality natural ingredients, free of chemicals, fillers and anything artificial. These supplements are more than just a product of our love; formulated with the help of leading veterinary experts, they're our way of giving back to the dogs who have given us so much.

At Furever Active, we believe it's unfair how little time we have with our dogs, but by keeping their brain healthy, we aim to give you more happy years together.
