Been taking for a week, and I do notice a small difference in appetite suppression. Does it burn fat? Too early to tell, but after a week, taking at night, I've noticed a difference. At this point, I would but again. The quality, ingredients, size and value for it's returned benefits are amazing.

Best fat burner
Verified purchase
I have ordered several Leanfire supplements, but this LeanFire PM is my favourite. It is good quality and a good size. The ingredients help with weight loss and the benefits are fantastic. There’s no taste to it and the dosage is great. I have ordered two more bottles already. I love this product. The others work great too, but I find it difficult to take something that I need to schedule - like 30 minutes before a meal etc. with my busy lifestyle I eat when I get the time and by then I’m usually starving and don’t want to wait 30 minutes.

Effective
Verified purchase
I find it effective since I feel smaller upin waking up. Good ingredients accdg to a clinical nutritionist since I am bit skeptical esp its for weight loss. four star coz theres slight palpitation but fade after an hour. During first week, I sleep earlier in my usual time after taking 30 mins before with 2 capsules. But I woke up early like 4 am and was not able to go back to sleep.

Super Effective!
Verified purchase
I added this on my weightloss program so i took 2 capsules before i go to bed. I weigh the next day or after 2 days i see my weight is going down steadily tho im going to gym as well but increasing and activating more my metabolism is a win win for me. Capsules a little big but just drink lots of water after. Doesnt cause stomach upset for me

⭐ Nighttime support for sleep, metabolism and weight management with multi-ingredient formula
Verified purchase
Really like this LeanFire PM because it supports better sleep, helps reduce late-night cravings and works on metabolism overnight using a blend of fat-burning plant extracts and calming ingredients, making it useful for weight management without stimulants.  The quality is solid with a combination of ingredients like citrus-based Sinetrol®, green coffee bean, green tea extract, L-carnitine and added sleep-support compounds like melatonin, valerian, hops and lemon balm, all working together in a stimulant-free formula with minimal unnecessary additives.  A good option if you want a dual-purpose supplement that supports sleep and metabolism as part of a structured weight-loss routine.
