  • Amazing for Lupus!
Size: 2 Pound (Pack of 1)
I was diagnosed with lupus (SLE) 10 years ago and the joint and muscle pain I experience can be very debilitating. This product takes care of that 90%. It allows me to function like a normal person. I have been taking MSM for a year and this brand for a few months now and have not experienced that pain while taking it. I do mega dose though and take 3 TABLESPOONS (spread throughout the day) as advised by my herbalist. As awesome side effects I also experience relief of constipation, fast growing nails, my hair stopped falling out excessively and sparse areas have filled in, and more energy and relief from depression (probably because I don't feel so crappy). I recently ran out of this stuff and thought I'd wait a couple of weeks to reorder (my money was a little short) and that was a BIG mistake. The joint and muscle pain came back in full force and I was completely wiped out! I quickly ordered more and as soon as I received it I took my mega dose and I kid you not the worse joint pain that I was experiencing (right wrist) was gone the next day! A few days later while on the sulfur my energy levels were back up. I am so amazed by this stuff. I have taken a lot of supplements and they never work this fast, if they work at all. I will not mess around any more and be without this sulfur. I'm going to start ordering in bulk. It's not curing the problem but it is helping me manage and without all of the garbage side effects that most lupus/arthritis drugs come with (prednisone!). I've tried different brands and I'm sticking with H2O. The crystals are large and I can tell the quality is good and it's obviously very effective for me. One thing just make sure you drink LOTS of clean filtered water if you take higher doses. Also, I know it's supposed to be better with vitamin c and I have never taken them together. I am going to start though and see if I get even more benefits (allergies). Will update after I have tried the combo. Update: 7/11/17 I am now taking it with 4 grams of vitamin C, for about 2 weeks now, and I have recently noticed that my sugar cravings are WAY down and this is coming from a sugar junkie (if there was a sugar rehab I'd be in it). I'm not sure if it's the vitamin c or the sulfur finally correcting that or the combination but I'll take it. I have peanut butter cups that I bought a few days ago and have not touched one. They just don't seem appealing anymore and were purchased more out of habit or just in case I got a craving. Also, this has nothing to do with the vitamin c but my hair is so THICK! It has never been this thick in my life! The strands are thicker and softer and I'm getting loads of compliments now. Just be aware you have to be patient and take the product faithfully when it comes to changes of the hair but the excessive shedding was the first to improve and then the rest followed. This stuff is the real deal and no I do NOT work for the company. Just happy to have found something that finally works. ... show more

  • Quality MSM Crystal Flakes
Size: 2 Pound (Pack of 1)
This seems to be a quality product. When I mix with about 16 ounces of water in the morning, I use a shaker bottle and a little patience for the crystals to dissolve. It does mix well. No smell, but a little bitterness in taste which is fine. Both myself and my partner feel a little better after taking these. I struggle with IBS-C and while this isn't a miracle, it helps my general feelings of wellness when I take it. ... show more

  • OUTSTANDING!! Words cannot describe the relief!!!
Size: 2 Pound (Pack of 1)
I had to write to tell everyone how thankful I am for this product! I had suffered with psoriasis for over "52 years" (I got the rash behind my neck two days after a small pox vaccine when I was four years old...per my mother). It never went away and would get worse depending upon how much sugar/junk food I ate. I spent thousands of dollars over the years on doctors and ointments with NO RESULTS. After taking this product for only TWO DAYS (four doses), my psoriasis is COMPLETELY GONE! Best part is, I've been eating some junk food and it still hasn't come back. That was two months ago! I am a customer for LIFE! It also took care of a two mean bouts of eczema/dermatitis I developed (with no results/cures after going to FOUR MDs...they were clueless...no offense)! Plain water burned my skin and sunlight was a misery! The rash (or whatever it was) was also all over my chest and front of my neck. Another benefit was that my all the pain in my arthritic right hand is now gone! (This took about a month....BONUS!) I have full flexibility back with NO PAIN! My knees are also not cracking as much when I bend them and my lungs feel clearer than they have in ten years!! After only two weeks, it also eliminated some small ulcerous looking sores that my boyfriend had on his shins for over two years that would not heal. (He's a meat eater and did not change a thing in his diet either and it still worked! Needless to say, he's taking sulfur twice a day too now!) God Bless H2O Air Water Americas and I sincerely THANK THEM for CARING TO PROVIDE PEOPLE with the very best!! Further, I am attesting that I am not being paid to write this nor is it a fabrication. I am going to post this on psoriasis support websites to try to help others...PAY IT FORWARD, PEOPLE! Don't support Big Pharma with their nasty drugs and side effects! If anyone has any questions, I'm happy to assist...it's the least I can do because I consider to have been given a great gift that has put much happiness back into my life!! P.S. I'm also attaching some embarrassing before/after pictures of those two eczema/dermatitis bouts I had and how it looked like someone punched me in the face, but I don't care. If this testimonial helps other people who are going through half the misery I went through, I'm going to swallow my vanity for that sake alone. ... show more
