Force Factor PM in 😴
Verified purchase
I have been sleeping so much better! Menopause and so many other things that make sleeping impossible! I can't wait until I get to the next bottle to say 100% that it's true. But so far, I have slept through the night since the 1st dose! it feels like it's been years since I slept this well! I will take it as long as I can 😴

⭐ 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.

I’ve been using this supplement for a few weeks now and I’m impressed with the overall quality. The packaging was secure, and the product arrived fresh with a good expiration date. Capsules are easy to take, and I didn’t notice any unpleasant aftertaste. In terms of effectiveness, I feel more consistent energy throughout the day and some improvement in recovery after workouts. Of course, everyone’s body responds differently, but so far this has been a solid addition to my routine. What I appreciate most is that the ingredients are clearly listed, without unnecessary fillers. The price is also reasonable compared to other brands, especially considering iHerb’s reliable shipping and storage conditions. Overall, a trustworthy product that I’d recommend to anyone looking to improve their supplement stack

Great quality, no side effects only benefits
Verified purchase
I’ve been using this powder for a few weeks, and the results have been impressive. I’ve noticed a significant improvement in my sleep quality. I fall asleep faster and wake up less during the night. In the morning, I feel more rested and ready to tackle the day. The product also claims to support fat metabolism, and while it's hard to measure that directly, I do feel more energetic and less prone to late-night snacking.

sleep like a baby
Verified purchase
the quality ingredients and small size make this an easy dosage to experience all the benefits. I sleep easy and have lost some stubborn weight due to my metabolism slowing down with age. I do practice good nutrion and exercise, this aids in my hard work and gives me an extra edge

I recently finished a 30-day supply of this supplement. While I haven't seen significant weight loss, it has definitely reduced bloating and improved digestion. My stomach was so flat in the mornings, and I felt light and energized. It also enhanced my sleep quality. The capsules are easy to swallow and don't have an unpleasant taste. Overall, it's been a great addition to my routine, and the ingredients seem solid. I'll be reordering this right away.

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
