So, will SST Support Lean Sleep really give you a better night’s rest and a nice surprise when you look in the mirror the next day? Read on to find out!

SST Support Lean Sleep Ingredients

SST Support Lean Sleep’s formula contains a mix of different herbs and minerals, all included in capsule form. And here’s what’s in each serving (two capsules): 

sst support lean sleep supplement facts


Magnesium is an essential mineral needed for hundreds of bodily processes. Related to sleep, magnesium helps to reduce cortisol and increase GABA levels, both of which result in greater relaxation and possibly better sleep. It’s often been called “the original chill pill” for these reasons. 

Research has shown that lower magnesium levels are associated with worsened sleep and that magnesium supplementation can typically improve sleep quality and overall sleep time. 

Also, of interest is that magnesium can benefit certain aspects of metabolism, such as insulin sensitivity, which makes it potentially useful for weight management. 

Plus, the AquaMin form used here is highly bioavailable.


SST Support Lean Sleep also included zinc, in the form of zinc citrate. Zinc is a trace mineral that has now been found to be involved in sleep regulation. And having adequate levels of zinc is essential for overall sleep quality and to reduce the risk of insomnia.


The last mineral included is chromium, in the form of chromate. Chromium is involved in protein, fat, and carbohydrate metabolism. And it also helps to improve insulin sensitivity. The overall evidence shows that chromium supplementation can help people lose weight and reduce body fat, while also maintaining lean muscle. 


Another ingredient in SST Support Lean Sleep is GABA, which is an amino acid that functions as a neurotransmitter in the brain. In fact, it’s the main inhibitory neurotransmitter in the brain and is necessary for sleep onset. Research shows that GABA is the most beneficial for reducing stress and anxiety and for decreasing the time it takes to fall asleep. This ingredient is commonly found in sleep quality supplements (such as GABA Brain Food).

Green Tea Extract

Next is green tea extract, which is standardized to contain 45% EGCG. The catechins and gallates found in green tea extract have been shown to slightly boost fat oxidation, metabolism, and thermogenesis, with modest weight loss benefits. 

Thankfully, this extract is decaffeinated, so it shouldn’t cause any sleep issues like normal green tea extract might. 


The amino acid l-theanine increases levels of GABA, serotonin, and alpha waves in the brain, which increases feelings of relaxation and calmness while reducing anxiety. And some research shows that theanine can improve the quality of sleep, largely by reducing stress and anxiety. In other words, it helps you get your zen on so you can shut off that damn mind and go to bed. 


One herb in SST Support Lean Sleep is chamomile, which is known to have an effect on benzodiazepine receptors in the brain, ultimately leading to increased GABA and feelings of relaxation. These sedative effects are likely why some studies show improvements in sleep quality from chamomile. 

Lemon Balm

Lemon balm is another herb that has somewhat similar actions to chamomile. Various compounds in lemon balm are able to stimulate GABA and offer anti-anxiety and anti-stress effects. And some research shows that lemon balm supplementation can improve sleep quality. 

Does SST Support Lean Sleep Work?

It is likely that SST Support Lean Sleep will work pretty well as a sleep promoter and possibly as a fat-loss supplement. 

All of the ingredients are well-researched and proven to offer benefits for stress reduction, sleep quality, and fat loss.

Additionally, most of the ingredients are high-quality forms, such as the chelated minerals and the standardized extract of green tea. But ideally, magnesium would be just in the form of Aquamin since there’s no need for magnesium oxide. 

Also, the dosages are in the effective ranges for the most part, except for chamomile and lemon balm which are dosed way too low. 

This limits the overall anti-stress effects of SST Support Lean Sleep, but given that there are optimal amounts of magnesium, zinc, theanine, and GABA, you still should see a decrease in anxiety and stress and increased sleep quality. 

The dosage for green tea extract is solid, but the chromium dosage is way too low, so this limits the potential fat-burning effects of this product. 

Claims vs. Reality

SST Support Lean Sleep should be able to reduce stress and anxiety, improve sleep quality, and help a little with fat loss. But these effects will probably be mild to moderate. 

In practice, you can probably expect to fall asleep a little bit earlier and wake up feeling a bit more refreshed. And you’ll also notice decreased anxiety and stress unless you’re really high-strung and wired up. 

You may also see some weight loss, but don’t expect anything other than maybe a few extra pounds lost over the course of several weeks. It’s a supplement, after all, not a magic drug.
