Pregnenolone is an essential prohormone that’s found naturally in our bodies. It’s a natural precursor to many vital hormones and neurosteroids (like DHEA - dehydroepiandrosterone) in our bodies that we need to function properly, stay healthy and perform at our peaks.

Taking Pregnenolone regularly can help you:

  • Support healthy hormone levels
  • Promote healthy cognitive brain function
  • Improve wakefulness
  • Improve your mood
  • Provide quality sleep

As you get older, the levels of pregnenolone in your body may decline. Taking Pregnenolone supplements provides you with a potential solution to maintain healthy levels of this vital chemical and keep your brain in the best state possible - even when you age.

Supplement Facts:

  • Serving Size: 1 Tablet
  • Servings Per Container: 100 
  • Amount Per Serving: 100mg or 25mg or 10mg (depending on bottle purchased)
  • Microcrystalline Cellulose, Magnesium Stearate, Stearic Acid, Croscarmellose Sodium, Dicalcium Phosphate

Activate Your Dopamine Receptors

Scientific studies have suggested that Pregnenolone may activate your dopamine receptors.

Dopamine in a neurotransmitter that performs several vital functions for your health and wellbeing:

  • Known as your brain’s “happiness chemical”, it’s closely linked to improving your mood and increasing your happiness.
  • Studies involving increased levels of dopamine have observed an increase in feelings of
  • This can lead to more time spent in the crucial “slow wave” deep sleep stage - leading to more energy, a better mood and better cognition in healthy individuals.

Could Support Improved Cognition

Scientists have proposed that levels of neurosteroids such as pregnenolone could serve as biological “markers” of cognitive aging.

Some human studies have also shown a correlation between neurosteroid levels, especially DHEA (which Pregnenolone leads to), and cognitive function.

Moral of the story: as your brain ages, your natural pregnenolone levels go down. Pregnenolone is a naturally-occurring hormone that plays an important role in brain function. Supplementation can therefore help support your overall brain health, learning and memory.

An Overview of Pregnenolone

  • Improves mood and well-being
  • Supports neuron activity
  • Supports deep sleep
  • Enhances motivation
  • Promotes relaxation and calmness 

The endogenous steroid pregnenolone (pregn-5-en-3β-ol-20-one) acts as both a precursor and as an intermediate in steroid biosynthesis [1]. It is naturally synthesized in the body from cholesterol.

As a neuroactive steroid (neurosteroid)[2], pregnenolone is able to interact with ligand-gated ion channels and cell surface receptors to alter neuronal excitability.

Pregnenolone has been shown to be involved in the support of learning and memory [3], and to affect neuritic outgrowth and axon myelination in rats.

Pregnenolone has also been shown to enhance levels of the neurosteroid allopregnanolone, which is known to have neuroprotective effects, enhance response of GABAA receptors, and to support inflammatory responses [4, 5]. 

Support of Healthy Cognition

  • Role in neuroprotection

As a neuroprotective signaling molecule, the pregnenolone steroid is involved in mechanisms supporting stimulation of neuronal activity in the brain. This role in neuroprotection is mediated by the enzyme aromatase [6]. Pregnenolone is able to support the growth of neurons and plays a role in the creation of new synapses [7].

Numerous studies have demonstrated that pregnenolone and/or pregnenolone sulfate is able to act at ligand-gated ion channel receptors. It acts a negative regulator of GABAA, kainite, and AMPA receptors, and as positive regulator NMDA receptors [7].

In mice, studies using glycoprotein NR2 subunits demonstrated pregnenolone sulfate has different effects in different parts of the brain; these effects are dependent on the developmental stage [8]. Studies using rat brain revealed similar findings when investigating mRNAs that encode subunits of the NMDA receptor [9]. Thus pregnenolone may play an important role in supporting stabilization and destabilization of a receptor’s active state [10]. 

Pregnenolone may also support cognitive function via the regulation of microtubules [7]. This helps to maintain neuron plasticity during healthy aging processes.

  • Boosting Mood

An important aspect of pregnenolone in relation to boosting mood is its role as a precursor of dehydroepiandrosterone (DHEA) syntheses in the brain. This steroid is involved in the modulation of synaptic transmission, and in dopamine receptor activation and release [11]. 

In the brain, dopamine acts a neurotransmitter (acting as a signal between nerve cells). There are numerous dopamine pathways in the brain, and it is involved in motor control, hormonal release and in the support of reward-motivated behavior.

Dopamine is important in the maintenance of mood in healthy individuals, and also plays a major role in reward, motivation, and salience [12].

Both Pregnenolone and allopregnanolone (3α,5α-tetrahydroprogesterone) may help to support the stabilization of mood, while pregnenolone might also support healthier irritability levels [13, 14]. 

  • Learning and Memory

Both Pregnenolone and pregnenolone sulfate are able to modulate NMDA receptors in rodents. They have been shown to support memory enhancement in spatial discrimination tasks in mice that lack NMDA receptors in the forebrain [15].

This steroid has been reported to affect object recognition memory when injected into the lateral septum of rats [16]. The lateral septum is known to play a key role in the support of stress responses and emotional processes [17].

Support of Deeper Sleep

Steroid hormones are reported to play a key role in sleep regulation. Perhaps the most clear relationship between steroids and sleep occurs with the hormonal cycling of estrogen, where imbalances caused by the menopause, pregnancy, and menstruation may lead to sleep disorders [18]. Likewise, as pregnenolone is reported to be involved in slow wave (deep) sleep it is expected to be involved in the support of healthy sleep patterns [18]. The effects of pregnenolone on deeper sleep seems to act independently of nocturnal cortisol and growth hormone [19]. 

Higher levels of pregnenolone are associated with enhancing paradoxical sleep and slow wave sleep. Pregnenolone alone can support paradoxical sleep without impacting wakefulness or deep sleep in rats [20]. However, the same research reported that higher pregnenolone dosages might actually impair wakefulness [21]. 

Response to Anxiety 

Administration of pregnenolone supports relaxation and a general state of calmness. As pregnenolone is a modulator of the GABA(A) receptor it is associated with reduced activity levels in areas of the brain involved in generating negative emotions [22].
