Cognitive Health

Here are some quirky facts about our brain!

It weighs about 3 pounds, and if you place your two fists palms together you can approximate the size.

About 75% water, 12% fat, 8% protein, 1% salt.

A specialized cell in the brain that transmits information (to other neurons). They form at an astounding rate of about 250,000 per minute before you are born.

About 86 - 100 billion. Most of your neurons you will ever have are with you at birth. Unlike a skin cell, when a neuron cell dies it is not replaced with a new neuron cell. (Science is exploring regeneration of the neuron cell.)

Neurons come in various shapes and sizes. They communicate with each other mostly via connections called synapses. There are hundreds (thousands?) of synapses for every neuron, so the brain has over 100 trillion synapses!

We do have memories of the first steps, first words, etc. Problem is we don’t hang on to them and the reason is not entirely known. (Science is exploring the concept of neurogenesis or the formation of new neurons which occurs at a greater rate during infancy and tapers off as we age.)

Moderate consumption of alcohol does not directly kill brain cells. Chronic long-term drinking can severely affect our physical and mental health.

Dr. James Kellaris coined the term ‘earworm’ to describe this phenomenon which happens more to women and musicians. “Who let the dogs out?” The reason why is not clear. “Who let the dogs out?"

ACHOO! - autosomal-dominant compelling helio-opthalmic outburst! Only about 30% of us have this reflex and it runs in families.

A. Nerves are cross-talking (optic and trigeminal) or

B. Pupil constriction causes mucus secretions in the nose or

C. A sensitive visual cortex.

A yawn is a stretching of the facial muscles. Why we yawn may be boredom or a sense of relaxation - including athletes prior to competing. Could be a way to cool the brain. We are susceptible to ‘catching’ a yawn from another when we can see things from their perspective; a social que of sorts.

Medical folks call this sphenopalatine ganglioneuralgia and trying to pronounce it can also cause the brain to freeze! It is simply the way the blood vessels and nerves on the roof of the mouth respond to cold.

A. Cold causes blood vessels to constrict and warm causes them to expand. The nerves send ‘pain’ signals to the brain which in turn causes the head to ache; or

B. The cold causes the anterior cerebral artery size to increase, which increases blood flow to the brain which in turns increases pressure and causes the head to ache.

First protect the brain as you drive your car (seat belts) or ride your bike (helmets). Adequate sleep (7 hours) is important. Food selection is important (serine rich diet!).

Exercise is important - mental (crosswords) and physical (walking every day).

We lose about 5% of our brain volume every 10 years after we turn 40 years old. This loss is mostly in the prefrontal cortex and hippocampus areas of the brain where our memory and attention lives.

The neurons ability to transmit information (neurotransmitters) declines as we age, they have a harder time communicating with each other. One reason we want to protect the neurons we have!

Eat well, drink in moderation and exercise. The science of brain chemistry continues to advance our understanding about cognitive support to minimize brain cell death.

About SERINE10

Click on any of the commonly asked questions below...

Serine is a non-essential amino acid derived from the amino acid glycine. It is important to overall good health, both physical and mental. Serine is especially important to proper functioning of the brain and central nervous system.

Serine helps form the phospholipids needed to make every cell in your body. It is also involved in the function of RNA and DNA, fat and fatty acid metabolism, muscle formation, and the maintenance of a healthy immune system. The proteins used to form the brain, as well as the protective myelin sheaths that cover the nerves, contain Serine. Without Serine, the myelin sheaths could fray and become less efficient at delivering messages between the brain and nerve endings in the body, essentially short circuiting mental function.

Serine10 is pure l-serine amino acid that is manufactured in North Carolina, USA by Ajinomoto.

Ajinomoto is the recognized world leader in amino acid research and production for over 100 years. The Ajinomoto Group serves over 700 million consumers in over 135 markets around the globe with their AjiPure logo recognized around the globe for purity, safety and efficacy.

Serine is used in the body in several ways.

First, Serine plays a central role in the production of the “myelin sheath.” Myelin acts as insulation for nerve cells and speeds the conduction of nerve impulses.

The parts of the brain and spinal cord that contain large amounts of myelin appear white and are called the “white matter” of the brain.

Breakdown or absence of myelin interferes with nerve impulses.

Second, Serine is important in the growth and development of cells by acting as the starting material for the building blocks of our genetic material (DNA and RNA).

Serine also acts as the starting material for the body’s production of nerve messengers (neurotransmitters) and lipid messenger molecules which play an important role in the normal development of the nervous system.

The US FDA has classified L-serine as generally regarded as safe (GRAS) for use as a food additive as long as it does not exceed 8.4% of total protein in the diet (CFR Title 21 Section 17.320.18).

The 10 refers to the amount of Serine (in grams) that is in one stick-pack.

Our understanding of how Serine impacts neuronal chemistry has advanced significantly in the past several years. Please see the Amino Acid section of this website.

Serine10 is intended to support cognitive health. Cognitive and neurological health refers to the health of the brain and its overall function. Specifically, cognition is the combination of several critical brain functions, including our memory, judgment, language, intuition and our ability to learn.

How we process information (think);

How attentive we are to our surroundings to make judgments (reason); and

How well we remember information that we see or read or hear (learn).

From the science and FDA trials it is documented that Serine is important for central nervous system development, the mechanisms of neuroprotection, neuronal signaling and synaptic plasticity. How this impacts our health is still being investigated.

The benefits of L-Serine are known to act on the neuron's chemistry and you may or may not feel any different after months of daily supplementation. However, the science supports the findings that daily supplementation of Serine over time may help protect your neurons from insult or decline in the cell’s ability to function.

There is no specific taste to L-Serine. Serine is clear and completely dissolvable in water.

We recommend 10 grams daily. It is always wise to let your physician or health provider know about your dietary supplements, including Serine10.

The research has shown that populations of people who consume close to 10 grams of Serine daily in their diet have exceptional cognitive skills well into old age. This is why Serine10 has 10 grams of Serine in each stick-pack - one packet per day will help you sustain a strong level of Serine in your diet.

Serine is a non-essential amino acid and we consume Serine through our diet. This website - Eat This Much - provides a list of foods and recipes rich in Serine. Aim for about 10 grams of Serine daily in your diet.

ECL is the company responsible for producing the Serine10 product. The idea for a convenient single dose packet of Serine came from the experience of taking Serine from a large bulk supplement package - it was messy, the dosage inconsistent, and not portable for an active lifestyle. Eastman Cognition Labs strives to advance the innovative legacy of the Eastman name in American commerce, translating innovative science to consumer products that improve our lives.
