Great product
It’s really working. I have used this product only five days . I fall asleep within an hour. I sleep much better and in the morning I feel rested.

It works!
This product helps me sleep, and it feels gentle. I do not think it has made my stomach flatten--the keys to that are probably in the kitchen and the exercise plan-- but I do feel healthy.

So glad I tried this!
Like so many others I have a hard time winding down at night after a day of running around with a million things in my mind. Opti core has honestly helped me relax for bed and get a great nights rest, I can tell a HUGE difference when I don't take it. I have a hard time sleeping in general and this has helped so so much, thank you 1st phorm!!

Essential for success!
I have used Opti Core in the past and it had a great impact on my quality of sleep and made a noticeable difference in helping to trim my waist line. As I work to reclaim my fitness I knew it would be imperative to incorporate Opti Core again. I love this product and 1st Phorm in general!!!!

5 stars on OPTI CORE
I love that it was easy , and I have tried a lot of products but none of them gave me these results , no lie or exaggeration. I take them 4 nights on 3 nights off , I never have a problem going to sleep or sleeping but this , made me feel restful not groggy
But rested.
I also stopped smoking , this August will be
1 year , so I was afraid of weight gain as well but I kept it in check , accept a little creeped on that's
Were I found OPTI CORE to help me and it did .
IT Took my stress away , and it was a big help to me , in a lot of ways . I also , did not use a vape or nicotine gum or any of that , I also saved all my
Money , that I would have spent on cigarettes
So , I was able to purchase the OPTI CORE ...
SO ...I got HEALTHY....WEALTHY .....and WISE.!!

I noticed a change in my core with in a week , and it gave me more confidence and more
Motivation. The fact of the matter is I work so many hours at my job , I didn't have time to work out , but I was so motivated that I started doing a few exercises on and off in the morning and walking at night , and making the time .
Out of the products , I have tried this was and is the best one for me , I just needed to get my stomach
Flatter than I had , I never ever want a roll ...lol
Not me !! Not healthy and does not look good or make you feel good .
I have also , recommended this to my friends ,
Who have all complimented me on my weight loss.
It's not like either I'm heavy , but , it was my confidence I had as well as weight loss.
I was also afraid , that I could not take them long term , but one of your mentors explain to me it's all natural , so I'm excited about that .
I hope you pick me to WIN !! Because , I would love
To buy another 6 bottles !!
Have an Awesome Day!!

Thank you

Sincerely ,

Kathryn Entwistle

Love. Love. Love.
If you’re having a hard time getting in some QUALITY sleep and feel run down during the day despite “sleeping” a “full 8 hours,” give this a try.
Also recommend if you’re having a hard time dropping some belly fat (which can be caused by elevated cortisol levels). Ease into sleep, rather than passing out with other supplements, and wake up refreshed, not like you need another 6 hours for the effects to wear off.
Great product!

The Best, By Far
This is, hands down, my favorite 1st Phorm product (and I am a huge fan, in general)! My quality of sleep is significantly better when using this. Even when I don't sleep as long as I'd like, I feel well-rested.

The only issue I have had is a slightly harder time falling asleep on the "off days", when not taking the supplement. This is minor, and the overall benefits far exceed that negative.

Works well without the drugged feeling
This has been the only product that has worked to shut off my mind at night and not make me groggy the next day. Crazy dreams and you can't take them 4 hours before you have to wake up, but given an 8 hour chance, they're amazing!

This product is honestly a life saver for me. First of all I suffer with insomnia. I can't fall asleep or stay asleep. As long as I give this product an hour or two ... I can lay down and be zonked out within 15min!! I also ONLY wake up to pee! The next morning I'm refreshed and not one bit groggy!! Quality of sleep aside ... this is a must have for me during high stress times and/or when I'm on prep for a show. I never believed that stress and/or lack of sleep could impact my body AESTHETICALLY until my coach ordered me (even if it meant skipping meals and skipping my workout) to GET SLEEP the second I arrived at the hotel the week that I earned Pro Status. I couldn't figure out why my body wasn't reacting the way it should. But he was right ... my cortisol levels were all over the place. I got 10 hours of sleep on night one .. woke up tighter. Got 9 hours of sleep night two and woke up dialed in and ready! I'll never skip taking this product again (except on the two days off that are suggested.)
