Dorothee R.

I am Not experiencing better sleep Unfortunately …. Although have been taking this nightly for obver two weeks - maybe i am doing something wrong?

Eamonn M.

I have been taking Magnesium Biglycinate and the Sleep formula a few weeks now as I had been having diffuculty sleeping for the past 12 months or so. I noticed an improvement within a few days in that I was finding it easier to get to sleep and staying asleep past 3 am. However, after a week or so, I noticed that I was having difficulty waking up in the morning and I always have a headache when I wake, although this does disappear after 30 mins or so. I'm not really sure I'll continue, it has helped but with side effects.

Bernadette S.

Still deciding if they help but the capsules are a little hard to swallow !

Arlene N.

Would % recommend been having the most blissful nights sleep these recent weeks definitelyre-ordering ... Pouch smelled like sweeties when i opened it Have a friend now taking it also Delighted I discovered your site ✌️&❤️

Margaret O.

I really appreciate the customer.service here. Every query no matter how small is treated as important. I also really like the supplement.

Kieran N.

I get a much deeper and more relaxed sleep now but still takes me soo long to get to sleep!

Great product to take alongside the sleep supplement, the magnesium combination in this formula is great for quality sleep, Definitely recommend!

Liam

Repeat customer they are that good

Pauline M.

I'm very glad it's pure as in no fillers etc I do feel it helps me sleep and with my muscle spasms at night it's a little expensive or it would be 5 stars ...I do intend to try the rest of the products too.

Mrs Pauline A.

I suffer from chronic insomnia and have been taking zopiclone for a few years and I thought I would give these two ago I could open a shop with everything I have bought so I thought try one more thing and WOW I have been taking them together for two weeks before I go to bed and for the last 5 nights I have fallen straight asleep which I haven’t done for years and stayed asleep I’m so so happy

Toni L.

Not tried this yet as I am currently working through a different brand... I am looking forward to using this to see if I experience a better result.

John H.

I think it does have a positive effect on my sleep, maybe not on a mega stressful night but under normal conditions the magnesium plus the sleep complex i think is improving my sleep, so will keep that combination going..... Hugh

Justin H.

This product has definitely improved my sleep so far.

Janet W.

I have been an insomniac for many years and have tried a number of sleep related products. I tried your Company’s Sleep product which was ok but not that successful. However I switched to Magnesium Bisglycinate and have had some good results. I am continuing with this product and am recommending it to a friend.

Janet W.

Although it is more effective than the Sleep package I can still only get five hours of sleep at night. I take three tablets one hour before bed but I still struggle to get to sleep. I shall keep persevering.
