Centrophenoxine: Benefits, Dosing, Where To Buy, And More!

Last Updated:

Key Information

Centrophenoxine is a nootropic agent:

Centrophenoxine is a combination of DMAE and pCPA that can enhance brain function and prevent aging.

Centrophenoxine has antioxidant properties:

Centrophenoxine can clear out cellular waste, increase glutathione production, and protect neurons from oxidative stress.

Centrophenoxine can improve memory and cognition:

Centrophenoxine can increase acetylcholine, lower lipofuscin, and improve learning and consolidation of new information.

Centrophenoxine is generally safe and non-toxic:

Centrophenoxine has been used for about 50 years without major side-effects, but some users may experience stomach issues, anxiety, or drowsiness.

In the quest for optimal cognitive performance and longevity, nootropics have gained significant attention. One such compound, centrophenoxine, has been the subject of research for its potential memory-boosting and anti-aging effects. Originally developed in France in 1959 to treat age-related cognitive disorders,[1] centrophenoxine has been used as the prescription drug Lucidril in some countries.

At Holistic Nootropics, our mission is to provide comprehensive, evidence-based resources to support mental health and cognitive performance. We believe in a holistic approach that extends beyond supplementation, encompassing lifestyle practices that foster overall mind-body health. In this guide, we’ll dive deep into centrophenoxine, exploring its mechanisms, potential benefits, dosing, safety, and more.

How Centrophenoxine Works

Centrophenoxine is a combination of two compounds: DMAE (dimethylethanolamine) and pCPA (parachlorophenoxyacetic acid).[2] It works through several mechanisms:

  • Increases acetylcholine levels in the brain
  • Reduces lipofuscin (age pigment) buildup in brain cells
  • Improves glucose uptake and blood flow in the brain
  • Increases RNA production to support protein synthesis in neurons
  • Provides antioxidant and neuroprotective effects

Compared to other cholinergics like alpha GPC and citicoline, centrophenoxine may provide gentler effects due to its indirect action on acetylcholine via DMAE.

Centrophenoxine is a DMAE-like compound that enhances many crucial age-related functions of the brain such as memory, neuroprotection, and clearing oxidative stress.

Potential Benefits of Centrophenoxine

May Improve Memory and Cognition

Several clinical studies have explored centrophenoxine’s effects on memory in healthy elderly individuals and those with dementia. While some studies reported improved memory consolidation,[3] others showed mixed results. Animal studies have also demonstrated learning and memory benefits,[4] potentially due to increased acetylcholine, improved neural efficiency, and neuroprotective effects.

Anti-Aging and Longevity Effects

Centrophenoxine has shown promise in animal studies for extending lifespan.[5] It may reduce age-related lipofuscin accumulation in the brain,[6] a process associated with neurodegenerative diseases. Centrophenoxine also provides antioxidant defense against oxidative stress and cellular damage.[7] However, the relevance of these animal findings to human longevity remains unclear.

Neuroprotective and Detoxification Properties

Centrophenoxine has demonstrated neuroprotective effects, shielding brain cells from toxicity and oxidative damage.[8] It may also help clear heavy metals and cellular waste products,[9] with potential applications in neurodegenerative diseases.

Dosage of Centrophenoxine

Clinical studies have used centrophenoxine dosages ranging from 600 to 2000 mg per day.[3][12] Typical dosing schedules involve divided doses taken with meals. As with any nootropic, individual variation is significant, and it’s essential to start with a low dose and titrate up based on response and tolerability.

Centrophenoxine DosageUsage
250-1000 mg per dayTypical dosage range used by most individuals
600-2000 mg per dayDosage range used in clinical studies
Divided doses with mealsRecommended dosing schedule to minimize side effects
Start low and titrate upBest practice to determine optimal individual dosage

Safety and Side Effects

Centrophenoxine is generally well-tolerated, with mild side effects reported in some studies, including:

  • Nausea
  • Headache
  • Insomnia
  • Dizziness
  • Irritability

Due to its cholinergic effects, centrophenoxine may be unsafe for individuals with seizure disorders, depression, or Parkinson’s disease.[13] Caution is advised for those sensitive to choline or at risk of acetylcholine excess. Pregnant and breastfeeding women should avoid centrophenoxine due to a lack of safety data. Long-term safety in humans remains unknown, warranting further research.

Centrophenoxine Stacks and Interactions

Centrophenoxine may be combined with other nootropics for synergistic effects:

  • Racetams: Potentially enhances acetylcholine and memory effects
  • Choline sources (e.g., alpha GPC, citicoline): Provides additional choline for acetylcholine synthesis

However, centrophenoxine should not be combined with anticholinergic drugs due to the risk of counteracting effects. Interactions with many medications and supplements remain unknown, so caution and professional guidance are essential.

Where to Buy Centrophenoxine

When purchasing centrophenoxine, it’s crucial to choose reputable vendors that prioritize quality and purity. Some trusted sources include:

Power-Up Your Memory

Look for products that offer:

  • Third-party testing for purity and contaminants
  • DMAE-free and pCPA-free centrophenoxine options
  • Capsule and powder formats for dosing flexibility

Be cautious when purchasing centrophenoxine on Amazon, as supplement quality and purity may be a concern.[14]

Centrophenoxine Discussions on Reddit

Is Centrophenoxine Effective?

User experiences with centrophenoxine on Reddit vary from strongly positive to lackluster.

Personally I havent noticed negative side effects yet, but not necessarily positive ones either except maybe a slight feeling of thinking more clearly.

u/ianm481 in discussion “Anyone tried Centrophenoxine ?”

Hit or miss for me. Some days a pleasant boost in alertness and cognition, others a small boost then a steep decline in mood.

u/BadBiO in discussion “Any experience with Centrophenoxine?”

Optimal Centrophenoxine Dosage

Most Reddit users report taking centrophenoxine doses between 250-1000 mg per day. Higher doses may be more effective but also tend to increase the risk of side effects.

My optimal intake is about 3 times a week.

u/insidethegod in discussion “Does anyone have experience with centrophenoxine ?”

Centrophenoxine Side Effects and Warnings

Common side effects reported by Reddit users include depression, irritability, headache, and insomnia. Some individuals may be particularly sensitive to centrophenoxine’s cholinergic effects.

I get really bad frontal headaches when taking DMAE, i finally gave up on it… The headaches respond well to acetaminophen, but I’d rather skip both.

u/DopePedaller in discussion “DMAE giving me incredible focus and clarify of mind. This is insane”

Where to Buy Quality Centrophenoxine?

Finding reputable centrophenoxine sources is a frequent topic of discussion on Reddit. Users express concerns about product quality and purity from certain suppliers and Amazon.

I recommend buying Centrophenoxine from Nootropics Depot because their product is pure and they provide a Certificate of Analysis verifying that purity.
