We answer some of the most commonly asked questions that came up when researching our lean pm Review.
Vitamin B6 - B6 is really more of an ingredient that you'd expect to see in an energy booster, or focus supplement. It's not really something that has much place in a night time fat burner, it's great if you're looking for more energy to help with a hard work out, but we don't really see any need for it's inclusion in Lean PM.
Magnesium is essential to help aid sleep, [2] but it's relatively rare as deficiencies go and in most trials it seems that magnesium deficiency can cause restless sleep, but taking it as a supplement is not going to make any difference if you're already getting enough. Although the possibility of being deficient is increased if you're on a calorie restricted diet of course.
Green Tea Leaf Extract is relatively par for the course in fat burners, but it's generally considered an ok ingredient.
L-Theanine does a good job at promoting sleep [3] it occasionally does make it into fat burners, but is as you'd expect more common place in nootropics. That said for what Lean PM is trying to achieve in this supplement it makes complete sense to include in Lean PM Night Time supplements. And 200mg is an effective dosage, so all in all this is a good inclusion for this sleep aid.
5-HTP plays a part in regulating serotonin, it's been demonstrated to reduce cravings [2]. and has a tertiary benefit on sleep as a whole. It's one of the best ingredients in weight loss supplements in general, 150mg is the ideal dosage so they also got this one right.
Melatonin supplements can help you get to sleep, in theory [4], but it's really only effective for a limited range of issues. It's not known to be effective at being a functional sleep aid supplement for people in a caloric deficit, and depending on the reason for sleep issues it's efficacy is shown to be mixed in trials. There's a reasonable amount anecdotal evidence to suggest that it is effective for a lot of people, so lean pm night time has made a reasonable choice here, but we'd need to see some more evidence to give it a complete thumbs up.
Black Pepper Fruit Extract - this is also known is bioperine, it's in a lot of supplements as it assists in the absorption of the other ingredients.
