Jarrow Formulas Alpha GPC is a phospholipid metabolite and precursor found concentrated in neuronal membranes. It is able to cross the blood brain barrier where it supports the synthesis of acetylcholine and neuronal phospholipids that are critical for cognitive function.

properties Alpha GPC
• supports learning by increasing the amount of major neurotransmitter acetylcholine
• acetylcholine allows for better information processing due to better transfer of data
• improves the signal transmission between neurones in the brain and central nervous system as well as with muscles in both direction
• may improve muscle strength due to better conduction of signals in neural networks and muscles
• thanks to the increase in acetyl choline, more bonds will form between actin and myosine, two major proteins which result in better muscle contractions, resulting in more muscle strength
• choline alfoscerate or Alpha GPC is along with omega-3 fatty acid DHA responsible for male fertility because of improved motility in sperm cells
• only contains the superior choline alfoscerate which is free of undesirable residues.
• is not banned by WADA, which means it can safely be used by competing athletes

background reading

  L-Alpha glycerylphosphorylcholine (alpha GPC, choline alfoscerate) is a choline compound naturally found in the human body and in dietary sources such as milk and soy. It is concentrated in the brain, especially in neuronal membranes, where it acts as a precursor to phosphatidylcholine. Phosphatidylcholine, despite often being referred to in the singular, is actually a class of phospholipids that contain an invariable alpha GPC moiety and two variable fatty acids. In the nervous system, phosphatidylcholines play important roles in membrane fluidity and membrane-mediated cellular signaling processes.
Alpha GPC also provides choline for the synthesis of acetylcholine (ACh), an important neurotransmitter involved in many functions in both the central and peripheral nervous systems. In the central nervous system, ACh is critical to the overarching processes of attention, focus, and plasticity that undergird learning and memory.
Alpha GPC is readily absorbed in the digestive tract and effectively passes the blood-brain barrier. Clinical research utilizing alpha GPC has concentrated on functional cognitive effects and neuronal protection.

Cognitively Alpha
A good amount of alpha GPC research has involved simulating cognitive decline and memory impairment in humans through the administration of scopolamine, a renowned compound found in species of the nightshade family, and determining the protective effects of alpha GPC. This is a useful model because scopolamine depletes acetylcholine stores, inducing a transitory cognitive impairment similar to that observed in normal aging. In vitro and animal studies have suggested that alpha GPC enhances hippocampal cholinergic transmission (critical for memory) by increasing acetylcholine synthesis and release.

In one study, thirty-two healthy, young volunteers received either 1200mg/day of alpha GPC or placebo for 10 days and also received either scopolamine bromidrate or placebo on day 11. Those who received alpha GPC and scopolamine showed significant benefits to attention and recall performance compared to those who received placebo and scopolamine.
Interestingly, even those who received alpha GPC but not scopolamine showed significant enhancement of recall performance compared to those who received neither alpha GPC nor scopolamine.

In another double-blind, placebo-controlled trial, 48 young men and women were administered 1200mg/day alpha GPC, idebenone, aniracetam, or placebo for 7 days. Idebenone and aniracetam are known cognitive stimulants.
On day 8, subjects received scopolamine. Alpha GPC enhanced learning, working memory, and long-term verbal memory, and the effects were significantly better than those seen with idebenone, aniracetam, or placebo usage.

Generates protection cortically
When choline availability declines, cholinergic cells go through autocannibalism to withdraw choline from phosphatidylcholine.
However, when the choline or phosphatidylcholine supply is not replenished, cells lose their ability to efficiently communicate due to the loss of membrane phospholipids that are critical for signal transduction and normal cellular functions. Supplementation of alpha GPC can help replenish both choline and phosphatidylcholine, which help maintain healthy neuronal membranes and neurotransmitter production.
In one study, animals given alpha GPC were observed to display adaptive and reparative reactions such as an increased number of ribosomes and hypertrophy of endoplasmic reticulum and Golgi complex.
Furthermore, the structures of the nuclear membranes and cellular organelles were better preserved compared to animals given the common nootropic agent piracetam. In addition, in vitro work using human brain slices has found that alpha GPC inhibits lysophospholipase, thus modulating membrane phospholipid breakdown and protecting neuronal cells from self-degradation.

Brain bioavailability
The pharmacokinetic profile of oral alpha GPC has been investigated in male and female rats given alpha GPC radio-labeled with either 14C-glycerol or 14C-choline. Hours after ingestion, both species were found concentrated in the brain. Furthermore, the labeled choline was observed in brain phospholipids within 24 hours of dosing. Excretion of labeled alpha GPC was minimal and comparable for both forms. These results suggest that oral alpha GPC is well absorbed, efficiently crosses the blood brain barrier, and concentrates in the brain.

Alpha GPC (L-alpha glycerylphosphorylcholine, also known as choline alfoscerate) is a phospholipid metabolite found concentrated in neuronal membranes. Derived from lecithin, alpha GPC is extremely well absorbed and crosses the blood brain barrier.
In the brain, alpha GPC supports brain function and learning processes by directly increasing the synthesis and secretion of acetylcholine.
Alpha GPC protects neurons and improves signal transmission by serving as a precursor to membrane phospholipids.

How to beat andropause, the condition that ails all elderly males

Andropause is a medical condition, similar to the female menopause, that can affect men between the ages of 40 and 65. Men do not have a clear-cut signpost to mark the transition. In women estrogen drops dramatically at menopause, but testosterone levels in men drop very gradually over many years and decades. The bodily changes in andropause occur very gradually in men and may be accompanied by changes in attitudes and moods, fatigue, a loss of energy, sex drive, stamina, and physical agility.
Andropause may be triggered not only by declines in testosterone, but in the "female" hormone estrogen as well.

There is a growing interest, as well as a booming industry, in the use of testosterone therapy for middle-aged and older men. This interest has led to the definition of a new condition, termed 'andropause' implying that this condition is due to falling levels of testosterone. This trend risks replicating both the rejuvenation fads of a century ago and the recent experience in estrogen therapy for menopause that has been propelled for decades by advocacy substituting for reliable scientific evidence. Is testosterone therapy appropriate for men with symptoms of male menopause? There is no scientific agreement on this topic.
But it stands to reason that hormones should be used only as a last resort since they have serious risks if misused.

Six reasons why eggs are awesome superfoods

Eggs are so nutritious they can be nicknamed nature's oldest superfood.
Eggs are abundant in essential vitamins and minerals as well as unique antioxidants and brain nutrients many people are lacking in their nutrition when they don't eat eggs regularly.

Here is a breakdown of the six reasons why eggs are such an awesome food choice

Nootropics, what are they and how do they work?

Nootropics is the accepted term for substances that enhance learning and memory function.
Nootropics work in various ways depending on the characteristic of the substance.
Some work by enhancing oxygen transport to the brain, an improved energy turnover in the brain, better neurotransmitter availability, or enhancing the creation of other substances that influence brain activity.

Uridine for a healthy brain and liver

Uridine supports formation of brain synapses and neuronal membranes 

Uridine is a nucleotide that acts as a precursor of brain synapses and membrane phospholipids in conjunction with the omega-3 fatty acid docosahexaenoic acid (DHA) and choline sources. It may enhance some brain cholinergic functions.
Uridine also supports the health and function of liver mitochondria.

Why do you look so familiar?

A common characteristic of most succesful politicians is their ability to remember people's names and faces very well. They have to, as networking is very important to them.

Seize the day, crack an egg?

In the past week, a discussion started between a dietician-foodie and a paleo/fitness-foodie, who embraced eating eggs without really giving a lot of arguments. The dietician wrote a critical article (in Dutch) to show the flaws of that bold statement.
