Schuessler Tissue Salts

Your body is made up of approximately 37 trillion cells and each of them are tiny energy conversion centres within which your body breaks down nutrients and oxygen to produce fuel for all your body functions. Your cells help you move, digest, speak, breathe and reproduce. But when nutrients in the body or blood are unbalanced your cells cannot perform optimally, which may cause dis-ease in the body. Schuessler Tissue Salts may support cellular function by providing essential minerals that contribute towards optimum health.

Schuessler Tissue Salts enter the bloodstream directly without having to go through the gut, which means faster and more efficient absorption of vital nutrients into our system. Although you may be eating a nutritious diet and taking health supplements, without these life-giving elements, your body may be missing some essential pieces of the health jigsaw puzzle.

Spray Tissue Salts Review by

After having all my teeth out and getting Dentures you can suffer with a lot of Ulcers and I find this product to be exceptional as you can carry it with you and use it at any time .

Excellant Product Review by

I have been using this for a while now and found it really good. On overseas trip got in a taxi my leg really seized up and sort of fell out of the taxi grabbed my spray and with a few minutes got rid of the cramp, as it was so sever had a couple more attacks during the night but it all disappeared after using the spray
Have recommended this to several people and ordered it for them as well.
I would highly recommend the spray

Muscle cramps Review by

My husband took this tramping with our super-fit sons. Each time he felt a twinge of cramp coming on he used the spray and never suffered cramp. After three days of strenuous walking he did not have the usual muscle pain and stiffness that follows. He won't be going without it again.

MAG PHOS tabs Review by

Great to have when I want to take something on a daily basis. I find them much better than a magnesium supplement and they seem much easier on the stomach. They also work extremely quickly. A wonderful product which I would recommend them to anyone.

3MAG PHOS 30ml spray Review by

I wouldn't be without this. Have it right by the bed, in case I need it during the night. Fantastic stuff. Son even uses it when playing hockey in case of muscle cramps and it works almost instantly.

Thoroughly Reccomend for a cramp free life. Review by

Both my partner and I have been taking this for several years after being recommended by a friend for cramp and restless legs, I fine it is much better than taking Magnesium supplement as this can cause an upset digestive system. Thoroughly recommend Schuesslers Tissue Salts

Just what I needed for Cramping. Review by

This product WORKS!!!!!!!

Amazing, can't live without! Review by

I take these daily for pelvic pain. It's also got rid of my eye twitch, reduced heart palpitations and helps me sleep during my second pregnancy. My toddler has a half when he needs. My husband also takes for muscle aches with good effect.

Schuessler Tissue Salts Mag Phos Review by

We always keep a container of these salts handy and my husband know to reach for them if his legs are fidgety or crampy. Great product have used them for years.

Mag Phos Tissue Salts Review by

I have suffered from leg cramps for years and finally have found something that seems to be working for me. I am taking one tablet morning and night and have been for about six weeks and am now cramp free. So far I am feeling very happy with the Mag Phos Tissue salts.
