Kavinace by Neuroscience is no longer available as a supplement.  April 10th, 2019, the FDA issued a letter to several nutraceutical companies to discontinue supplements containing 4-amino-3phenylbutyric acid.  The FDA has determined that 4-amino-3phenylbutyric acid, also commonly referred to as Phenibut is not a dietary supplement. We published a previous Kavinace article shortly after the FDA letters were sent out. 
As of the letter dated April 10th, the companies had 15 days to comply.  This left people that had taken Kavinace safely for years in a bit of a quandary.  Kavinace is, I mean, was a dietary supplement that many people took to help with staying asleep.  It contained 950mg of a combination of taurine and 4-amino-3-phenyl butyric acid HCL per capsule.  
Most people did well on one to two capsules taken at night before bed.  It wasn't a sleep medication, like Ambien or Unisom but did help to raise GABA to help with staying asleep at night.  I used this myself and with patients to stay asleep at night.  
Commonly in perimenopause and menopause, women have trouble staying asleep.  Often they fall asleep easily but will wake up in the middle of the night for hours.  And by the time they are able to fall back to sleep, it is time to wake up for the day.  Kavinace was very helpful because it contained 4-amino-3-phenyl butyric acid, which is a precursor to GABA.  Meaning it is easily digested and can cross the blood-brain barrier to help convert to GABA and stimulate GABA receptors to stay asleep. 
One of the reasons that sleep is so important is terrible sleep can make you gain weight.  People, especially women, will gain weight easily if they do not sleep well at night. Sleep is necessary for so many health reasons, it is also responsible in part for your metabolism.  It really goes back to our adrenal glands.  
The adrenals secrete cortisol in a diurnal fashion.  Meaning that cortisol is released highest in the morning and stays up through the day and drops at night so that you can sleep well.  Commonly, (especially in hormone imbalance, perimenopause, and menopause) you will see cortisol rise in the middle of the night. That causes us to wake up in the middle of the night for no reason. 
Other than it is aggravating to be awake for hours in the middle of the night and tired during the day, the elevation of cortisol at night can negatively affect metabolism. Often we tell patients, forget waking up early to go to the gym.  Just get that extra hour of sleep. One of the first things that we work on with patients is sleep. Sleeping properly is great for the waistline. 
Well you might be asking, Kavinace is no longer available, what do I do now?  There are many options available to replace Kavinace and sleep well. Back when I first found Kavinace years ago, all we had available to us was GABA.  GABA is a huge molecule that is not easily absorbed through digestion, so it was a waste to take. Now we have available, PharmaGABA, which can be absorbed through the digestive tract.  
PharmaGABA is a great alternative to Kavinace.  You can take it as capsules at night or chewable tablets.  If you are a tough sleeper, and still wake in the middle of the night, you can chew up 1-2 more t
