What Is Alpha GPC 50% Powder?

Alpha-GPC is a naturally occurring compound that is actually found in our brain and also in some food sources, including eggs, dairy, meat, and fish. Alpha-GPC, also known as alpha-glycerylphosphorylcholine and choline alfoscerate, can be produced synthetically or derived from natural sources, and comes in powder form but can be added to capsules as well.

Alpha-GPC is a choline-containing nootropic compound with much anecdotal evidence suggesting it may help with both athletic and cognitive performance, and one study shows Alpha-GPC powder to benefit brain health.

Nootropics Depot offers both Alpha-GPC 99% powder and Alpha-GPC 50% powder. Our Alpha-GPC 50% Powder is available in 30 or 60 grams.



Alpha GPC Benefits

  • Improved athletic and cognitive performance - Some scientific research on rodents and anecdotal evidence suggest that Alpha-GPC may support cognition in healthy adults.
  • Brain Health - A 1994 clinical trial in Italy of more than 2,000 people showed that Alpha-GPC benefits overall brain health. Varying doses over the course of 6 months resulted in statistically significant improvement in cognition in three of four measurement scales.


Alpha GPC Dosage

The typical dosage for Alpha-GPC 50% Powder is 600-1,200mg daily, taken in one or two doses of 600mg. It’s a good idea to start out with a smaller dose and work your way up if necessary.

Where to Buy Alpha GPC 50% Powder?

Nootropics Depot offers a naturally sourced Alpha-GPC product. Alpha-GPC is GRAS-affirmed by the FDA (Generally Recognized As Safe).

Alpha-GPC 50% Powder is a great option for anyone who lives in a humid climate. While Nootropics Depot takes care to prevent clumping of the powder, Alpha-GPC is a hydroscopic compound, meaning it absorbs moisture readily from the air and can turn into a gel if not properly stored. Alpha-GPC 99% Powder is more sensitive to hydroscopy, so the 50% powder is a good choice if this is a concern.

If your Alpha-GPC 50% Powder does arrive with clumps, simply break them up with your fingers. Storing this nootropic in an airtight container can help as well.

Product contains one 30g or 60g jar of Alpha GPC 50% Powder. 

Other Ingredients: Calcium Hydrogenphosphate, Silicon Dioxide

    critical for any higher cognitive function

    This is a high quality choline source. It’s necessary for Max racetam effects. But even when I’m not taking racetams it seems to allow my mind to have. It’s like fuel. Allowing my brain to operate without fog. With clarity and completion.

    My First Combo

    I had tried noopept before but this is my firts combo: Noopept+Aniracetam+Alfa GPC. Aniracetam is more slowly release, but mind is focused and also i notice a slighly lees anxiety. Noopept is more quickly in the effects, and you can experiment clarity in mind and also in the eyes.
    The team in the web is so kindly. I had lot of problems with the parcel but at least i could have it.

    Alpha GPC

    Great Stuff! Thank you!

  • Brandon - 22nd May 2018

    This is the one you want...

    If you are going to get Alpha GPC, get this one. It's 50%. Why get 50% when you can get 100%? Because it remains very stable when stored and never clumps up or changes.

    i love it

    Alpha-gpc is pretty good. I remember my dreams alot more now

  • Drew - 5th Mar 2018


    Alpha-GPC is now the most important supplement in my nootropics arsenal. Within seconds of taking I feel alert, wakeful and ready to go. After taking it you feel mentally motivated and ready to do a challenging task like a crossword puzzle, even if before you felt mentally tired or burned out. The ability to calmly focus for hours on end if needed is worth it alone. I take Alpha-GPC every morning. Stacks extremely well with everything else I take. The 50% version is perfect, still plenty strong for me and resists clumping or becoming a sludge from hygroscopy. Perfect quality as always from ND. If you're on the fence, buy it. It works.

  • Matt Eckert - 5th Mar 2018

    Alpha GPC - the choline for me

    I stack this with other nootropics. Works perfectly. I'm going to try the 99% powder next time around.

  • Aidan - 4th Mar 2018

    Great with piracetam

    I had heard that the combination of these 2 works well together. When I tried both and piracetam separate, I could tell that alpha gpc did the job of keeping headaches away and adding to my concentration. Its not really a supplement to take separate but with something else long term basis. Also keep in mind the % sold. I take around 600mg 50% alpha gpc daily because it is only 300mg of pure alpha.

  • Unknown - 26th Feb 2018

    perfect for my needs

    Use it whenever I take a racetam., which is daily. Gives my brain plenty of acetylcholine .

  • Alex - 17th Feb 2018

    Subtle effect

    Quality product for reasonable price, the effect is subtle. I take 300mg twice daily with food.

  • Edward C. - 11th Feb 2018

    Was not water soluble

    Was not water soluble compared to the products I purchased with other vendors which really surprised me. Also did not come with the measuring spoon. Not as good as Powder City but they are out of business.

    ND Admin: You bought 50% Alpha GPC, not 99%. The other 50% is a stabilizer to prevent it from absorbing too much moisture out of the air. It's entire purpose is to prevent water from adversely affecting it... If you want 100% water solubility, you need to get the 99%. It's why we offer both forms.

    Memory recall improved drastically and brain fog gone

    I love this product. I am a 53 year old woman. For several years I have suffered from brain fog and memory problems. It was frightening to me. My son gave me Alpha GPC 50% powder. I faithfully took it every morning in a drink. I started noticing that I was able to hold onto a thought and retrieving information as a normal person is supposed to. Sharper and have clarity. The brain fog is completely gone and my memory is great! I ordered Noopept and have noticed even more benefits since using that with Alpha GPC. Thankful for these products. ❤️

    Great active ingredient, poor mixability.

    I've been using alpha gpc from nootropicsdepot daily for upwards of 18 months. As far as the actual effects of the product go I've never had a single complaint. Unfortunately this batch has brought about a problem I've never faced before, incredible grittiness when mixed with water. Very disappointing.

    ND Admin: This is the Alpha-GPC 50% powder. It is mixed with compounds to help stabilize the hygroscopic (water absorption) properties. Pure alpha-GPC is very hygroscopic, and absorbs water from the air. That makes it hard to use in powder form. The 50% powder is a lot more stable in powder form. However, that also means it till not fully dissolve in water as easily as the 99% would. That's kind of the point of the 50%, though. If you want to mix in water, the 99% is much better suited to that.

    We've also recently improved the stability of the 50% from being affected by moisture. So the more recent batches are more stable from humidity than older batches, but that also can mean it is harder to dissolve fully in water.

    noticeable increase in energy and motivation

    The product is high quality, I am starting with a low dosage and the results are fascinating, can't imagine how it will be when I start to take the full dosage.

  • Geoff - 15th Aug 2017

    Works well

    The consistency is great and the product works well. I'll be reordering when I get low.

  • Geo - 5th Aug 2017

    I love the racetams

    Stacking Oxiracetam, Phenylpiracetam, Alpha-GPC 50% and L-Theanine in a fruit smoothy with a cup of coffee mixed-in, and all systems are a go for your day. Blend them all together, take half in the morning and the rest in the late afternoon and you will have a great day my friend. You may have to smoke something in the evening to sleep, but that brings with it another type of deep contemplative high. Six months of this, mixing up your daily routine with some Adrafinil or better yet Modifinil, and you will be a completely different person.

    Best A-GPC around

    Not going to talk about benefits, just google them.
    I have bought many brands and this one by far has the best consistency.
    Mixes readily with any juice or even plain water.

  • CD - 9th Jun 2017

    No Qualms

    Great company, great product, fast shipping. Extremely fine powder and does not clump. This has worked wonders for me.
