Excellent product Review by

This product works so well. I care for a long term disabled person who cannot move and has had ongoing problems in this area. I find one a day of these keeps them regular.

Wonderful Product Review by

About 15 years ago I had major Bowel Surgery that was not completely successful and although the specialists tried a variety of different products to help me none seemed to work well until it was suggested to me ( not by a Doctor or Specialist ) that I try MG LAX that works wonderfully. The specialists have since told me if it works use it so I am. I use a dosage of 4 tablets daily to keep things regular, if I use less it doesn't work. I purchase at least 4 bottles at a time. Very fast service as I cannot be without this product. An absolutely wonderful reliable product and will need to be on them for the rest of my life unless I wish to go to a bag, that no one would do unless it is the last resort

A product well worth it's value. Review by

I have had a poor bowel ever since having my daughter by caesarean 8 years ago, became reliant on laxatives. Since I came across this product I will not be looking back and having to use a laxative again!!!! It took a bit of juggling to work out the right dosage for me. I did the rapid dose in the beginning but only had to take 2 lots of 4 tablets and it certainly worked!!!! Then I took 3 tablets per day and they only seemed to work every second day. I think it has just taken my body a little to adjust to them. I am now on 2 per day and they work every day. Brilliant product. Fast postage, I order 2 bottles at a time so that I won't be without them.

Get them to send to UK as the only thing that helps! Review by

After leaving NZ, I scoured UK shops and web looking for a product. One sea magnesium product helped a bit, but not like these! So i shipped them in. Nothing helps like this. Highly recommend you give these a go.

Great Find! Review by

Like this product. I just take one every second day after initially taking two a day, which I found too much, but now the lower dose seems to do the trick.

These are awesome. Review by

These are great. I have only been taking two tablets daily and they work great. I am going regularly now and am feeling much better for it. Would highly recommend.

Works amazingly for me Review by

First time i have tried this product and i use it in conjunction with red seal alpine tea. Absolutely amazing and instant. I have only done the rapid in which i have taken 4 tablets with an alpine tea and within an hour i am in the toilet cleaning everything out. Only down fall is that i need to do this when not at work as spent a lot of time in and out of the toilet and the smell was not pretty! Luckily for me this product has been great and i will always make sure i have some in the cupboard as it definitely cleans me out and leaves me feeling lighter and comfortable. Please note tho i have only used this product in conjunction with the alpine tea so cant 100% guarantee that it is this product alone that provides outstanding results or if it is by using the two products together.

Highly Recommended Product Review by

Last year I had sepsis and had to be on antibiotics for 8 weeks, after I'd finished the antibiotics I became very blocked up and nothing was helping. Once I started taking Mg Lax my problems were solved, there is no sudden trips to the bathroom either which is great.

Try them they work! Review by

I'm 25 and I've had serious bowel problems for the last 10 years. Had multiple surgeries, tried laxatives, alpine tea, vit c, kiwifruit, prune juice, metamucil, probiotics, allsorts. Nothing really worked and if they did you got diarrhea when they did, not ideal at work. I've been taking two of these pills at night and in the morning for a few weeks now and they are great. First normal toileting I've had in years! And you're not running to the loo with diarrhea and no more constipation for weeks :) Give them a go, best thing I did and they are relatively cheap.

They Work! Review by

I have probably IBS - C caused by methane producing archae, eg, SIBO. Nothing makes me poop. No food regimin, no laxative, not even usual high dose vit c, mag. But these work. And for those of you who know the tension around not pooping.....then these might be a good bet for you too. Wasted my time with everything else. A great support for the system while i figure out how to heal it. And great value too! 4 at night makes my poop like a thick liquid tar in the morning, so now titrating down to 3 at night. :)
