Product Overview


  • Completely Natural
  • Sodium Free
  • Prevent Leg Cramps
  • 288 Servings
  • A Freeze Dried Instant Calcium Magnesium Drink

A to B Calm is the original and only freeze dried instant calcium magnesium drink. Try it with tea or juice or by itself.

Calcium and magnesium have been used for years as a natural remedy for pain, tension, stress and strain. However, conventional cal-mag supplements are sometimes difficult to assimilate. Calm's freeze dried formula makes the calcium and magnesium into a tasteless drink that is easily and rapidly assimilated.

  • Take before bedtime to prevent night leg cramps and twitching. Calm is beneficial for restless leg syndrome and other muscle cramping.
  • Calm helps you relax and sleep without prescription drugs.

Suggested Use

Put one level teaspoon of Calm in one half cup of boiling water and stir until completely dissolved. Fill cup with cold water or juice, and drink.

For use as calcium supplement, use one heaping teaspoon, 362 mg Calcium, 70 mg Magnesium, two or three times per day, as needed.


Some settling may occur

Calcium gluconate, magnesium carbonate and vinegar.

1 tsp. contains 181 mg Calcium 35 mg Magnesium.

iHerb Customer Reviews

I don't think I can do without this for restless legs.

Posted by Reviewer1582777 on May 25, 2014

I take this in the evenings, which is when the twisting in my legs is worst. This is a great product. Don't ever discontinue!

It works, but, to be honest, isn't the flavour of the month. I really wish that iHerb would stock CalMag-C. It's far and above the best of its type.

This stuff is amazing!

I first tried A to B Calm on the suggestion of a masseuse. He mentioned that with the combination of tight muscles and fibromyalgia I would possibly benefit from this combination of calcium and magnesium for allowing the muscles to relax, and heal, while sleeping. There are others out there, but this is so quickly assimilated, and there are no fillers, so I have found that I am sleeping much better, and waking much looser, as well as not waking in pain! I have been taking it every night, and haven't found any reason not to!

I did not like it much

Posted by Reviewer2206151 on Feb 25, 2010

It tastes sour and I like in other products they have plenty of other supplements the body may need.
