It's a common industry practice that brands will flood their customer review sections with fake positive reviews and although we can never be sure, it's simply far too accessible, worthwhile and difficult to detect that you can never write it off entirely as a possibility.
On their host webpage, Envy Nutrition Night Time has a 5 out of 5 star rating, and this struck us as a bit peculiar as of the 5 reviews displayed, three were two stars and complained there was no detectable weight loss effects. There was a four star review that carried the same complaint but clarified they had just began using and then one 5 star review that complemented Envy Nutrition for helping them to fall asleep more easily.
On Amazon there is a staggering 22,037 reviews, through which this night time fat burner has earned a respectable 3.6 out of five. Looking deeper there's some extremely complimentary 5 out of 5 reviews, but these are suspiciously interspersed with more honest looking reviews all complaining there has been no detectable weight loss since taking this weight loss supplement.
Vitamin D 30mcg
Vitamin D (or more precisely Vitamin D3) is one of the more common fat burner ingredients, and there's very good reason for this.
Firstly, Vitamin D plays a role in regulating our hormone levels which can have positive effects on mood regulation, reducing comfort eating tendencies.
Secondly, over 24% of Americans are considered to be deficient due to our propensity to spend less time in the sun than we really should. We found a trial that shows there is a link between this deficiency and an increased difficulty to lose weight. The trial observed the weight loss of 44 obese patients that were also vitamin D deficient, and found those who supplemented reported significantly higher weight loss than those on placebo .
The dosage here is solid, the recommended minimum is 15mcg so 30mcg will get the job done and then some. If you're concerned this may be too much you can rest assured, as vitamin D supplementation goes as high as 1,250mcg and is still considered safe.
Proprietary Night Time Fat Burn Blend 500mg
Now this is where this night time fat burner loses faith with us, as the use of a proprietary blend is a massive red flag for any weight loss supplement. It's a common way to sneak in really high quality ingredients without actually paying to dose them properly, dumping all of that revenue into the marketing budget instead.
500mg doesn't leave us a lot of room to play with, so although we can't know for sure exactly where the corners have been cut the hardest, there are some ingredients here that simply would not be effective even at the full 500mg capacity, yet there are 8 ingredients total here.
Let's get into it
The Fat Burner Side
Here we'll go through what ingredients there are that are included for their effects on weight loss and otherwise fat burning effects.
White Kidney Bean Extract
White kidney bean extract is an excellent inclusion in any modern fat burner, though right out of the gate it's inclusion here is kind of baffling simply due to the fact this is a night time fat burner that has ingredients that serve as a sleep aid.
What makes this ingredient so great is how it affects our bodies carbohydrate digestion. It might sound too good to be true, but white kidney bean extract has been observed under scientific testing to work as a genuine carb blocker .
The problem is that it was dosed at 50mg/kg, meaning the average human would require a dosage of 4 grams, or 8 times to entire contents of this proprietary blend.
Green Coffee Bean Extract
The active ingredient here is what coffee is best known for: caffeine.
Caffeines use as a weight loss supplement is well documented, as it has been found to reduce caloric intake if ingested anywhere between 0.5/4 hours before a meal . It has also been found to increase the rate at which our bodies burn fat via a process known as thermogenesis .
The dosage here is difficult to say. The reason we say this is because of how commonly the envy night time fat burner is praised for its effectiveness as a sleep aid. We all know caffeine negatively affects our ability to sleep so it's our guess that there is an ineffective amount of this ingredient.
Body fat is a concept we're all familiar with, and it's common knowledge that we store this body fat as a way to "bank" the energy we get from food when we over-eat. Scientifically we understand this as white adipose tissue being the banked energy, and brown adipose tissue being the body preparing this energy to be synthesised .
L-theanine has been found to affect the browning of white adipose tissue , but at a dosage of 50mg/kg, which simply wouldn't fit in when compared to the average American with an approximate average weight of 80kg.
The Sleep Aid Side
So that's all for the weight loss, though there is certainly an argument that maintaining a healthy sleep schedule will aid in weight loss as well.
An essential amino acid that is used commonly as a treatment for many sleep disorders due to its relationship with serotonin. We found a trial that observed significantly reduced sleep latency when dosed at 1 gram, but went on to state that doses as low as 250mg produced a trend in the same direction .
It's unlikely there's as much as 250mg held within this blend as it would leave very little room for the rest of the ingredients, but as an essential part of anyones diet we're certainly not complaining that it's here.
Valerian Root Extract
The roots of Valerian have been used widely for their ability to induce sleep and improve sleep quality, being the most commonly used herbal product to induce sleep in both the United States and Europe. You'll see it in many of the highest quality sleep aids for this very reason.
We found a study of 16 trials that included over 1,000 patients that concluded a statistically significant benefit to supplementing with valerian root, with 80% of patients reporting improved sleep .
The doses presented here were everything between 225mg and 1215mg so we again would presume that this is under-dosed.
Lemon Balm Extract
A herb from the mint family, Lemon balm has seen used as far back as the middle ages to reduce stress and anxiety, promote sleep and ease pain and discomfort from indigestion.
We couldn't find any clinical trials that advocated for it's use as a sleep aid or fat burner, except for one which concluded when combined with an extract from the plant Nepeta Mentoides Boiss it may improve insomnia and its co-morbid depression and anxiety .
The herbal supplement Passiflora Incarnata that has seen use historically as a treatment for anxiety, insomnia, seizures and hysteria.
We were able to found a study that used Passionflower tea before bed against a placebo, and observed that a low dose of Passiflora Incarnata, when in the form of tea, yields short term subjective sleep benefits for healthy adults with mild fluctuations in sleep quality .
We did find another positive clinical study from 2020 but this study failed to report dosage, method on supplementation (It's not automatically dietary) so we won't be included this.
Overall there's very little clinical evidence for the use of passionflower extract as a helpful sleep supplement, though this is because of a lack of high quality testing rather than contradictory results. What we can gather then is that more testing is needed, there's still hope for this one.
The absolute grand daddy of sleep aids, melatonin. Within the brain lays a very small gland that secretes this hormone in response to darkness, with the express purpose of making you feel sleepy. With this in mind, you can see how it is one of the most common and effective sleeping tools available today.
We found a systematic review that included 35 randomised control trials. The study found positive results in the initiation of sleep through melatonin supplementation as well as the more restful sleep reported .
In terms on dosage there was a large amount of variance in these trials but typically speaking 10mg is the most you'll need, so we imagine this has been dosed correctly within the Envy night time fat burner.
Is Envy Nutrition night time safe?
Thanks to its formula being entirely made up of natural and clinically tested ingredients, envy nutrition night time should safe for consumption for the vast majority of us. We will always recommend you speak with your doctor if you have any concerns.
Any Envy Night Time Side Effects?
Thanks to the use of a proprietary blend we can't 100% guarantee this, but there is likely so little of each ingredient that we doubt there will be much of an effect at all, at least when considering the fat burner ingredients.
Some people have described waking up in the middle of the night and feeling disoriented when taking melatonin as a sleep supplement, so this effect may take place as the usual dosage is around 10mg, which would easily fit into the proprietary blend of 500mg total.
