Choline Bitartrate (500mg)

Choline Bitartrate is converted to acetylcholine in the human body. Acetylcholine (Ach) has a variety of benefits that include slowing the progression of dementia, improving nervous system function, and moderating sleep cycles. Ach helps regulate your body’s circadian rhythm, and is strongly associated with REM sleep. The maximum recommended daily dose of Choline is 3,500mg.

L-Glutamic Acid (80mg)

Glutamic acid is the most commonly occurring neurotransmitter in the Central Nervous System, and is important in the treatment of schizophrenia, depression, anxiety and other mood disorders. In SENTRA PM, L-Glutamic Acid helps make GABA, a very important neurotransmitter that helps initiate and maintain deep sleep. Low levels of GABA are known to interfere with deep sleep, such that people with low levels may wake easily and often throughout the night, missing out on meaningful amounts of this crucial slow-wave deep sleep.

Acetyl L-Carnitine HCL (80mg)

Research suggests that L-carnitine reduces feelings of fatigue and tiredness upon waking especially in patients living with fibromyalgia and mild depression. In SENTRA PM, L-carnitine helps boost acetylcholoine production and ensures that your nervous system has the fuel it needs to initiate and maintain restful sleep.

Griffonia Extract - Seed (11mg)

Griffonia seed is a natural source of 5-HTP, an amino acid that helps the body make serotonin. Serotonin is an important neurotransmitter that plays a major role in sleep, pain, and appetite control. Serotonin initiates sleep and decreases the amount of time it takes to fall asleep. Serotonin is converted to the sleep hormone melatonin when it is dark, and is responsible for regulating circadian rhythms. The maximum recommended daily dose of 5-HTP is 400mg per day.

Cocoa Extract (fruit)

In SENTRA PM, the theobromine found in cocoa extract works as a temporary Adenosine Inhibitor, helping important neurotransmitters initiate sleep and promote nighttime nervous activity that helps repair damaged cells.

Ginkgo Biloba (leaf)

Ginkgo has been linked to an improvement in cognitive function in patients suffering from dementia. In clinical research studies ginkgo was shown to improve sleep efficiency by preventing nighttime awakenings. Ginkgo was also found to enhance Non-REM sleep, and improve the stage 1 sleep. In SENTRA PM Gingko doubles as a Neuron Uptake Stimulator, helping cells work better.

Hawthorn Berry

Hawthorn Berry is an antioxidant and anti-inflammatory used in SENTRA PM to improve sleep processes and maintain cellular health throughout the nervous system. In Sentra PM Hawthorn Berry acts as an Attenuation Inhibitor, helping prevent tolerance to the product so that you can take the same amount for a long time without needing to take more.
