I am very pleased with this magnesium citrate product, as I have had trouble with other forms of magnesium, not being able to tolerate them. This easy-to-swallow capsule works great in combination with Swanson's Premium Calcium Citrate Complex with Vitamin D. Both are in capsule form, so there is no threat of a large chalky tablet getting stuck in your throat. I take one Nutricology Magnesium Citrate capsule to 3 capsules of Swanson's Calcium Citrate Complex -- not only do I get the superior citrate form, but this combination is perfectly balanced for me. I experience none of the problems sometimes associated with other forms of Calcium and/or Magnesium. Highly recommended. And a big "Thanks" to Swanson's for making this superior citrate form available in a capsule at such a great price.
