The Best Calcium For Osteoporosis: What Price Should You Pay?

The best calcium for osteoporosis prevention doesn't have to be expensive. But it must include enough vitamin D, K2 and magnesium to prevent calcium from migrating to our heart.

The best calcium for osteoporosis will include all of the following ingredients within two tablets:

  • 1,200-1,500 mg Calcium
  • 800-2,000 IU of Vitamin D
  • 420 mg. of Magnesium, and
  • 120 mcg. Vitamin K

The above calcium and vitamin D targets are recommended by national osteoporosis societies for women over the age of fifty.

The vitamin K and magnesium targets are the upper levels recommended within the Recommended Daily Intake (RDI) followed in the United States and Canada.

The best calcium for osteoporosis doesn't have to be expensive. The table of product comparisons below show that there is no relationship between product quality and price of bone building supplements.

Vitamin D3 400 IU Available Not available Not available Available Available
Magnesium 150 mg Available Available Not available Not available Not available

The recommended Jamieson Calcium Magnesium provides 333 mg of chelated calcium rather than 500 mg of calcium as specified in minimum ingredients. Additional information on chelated supplements and calcium absorption may be found at Calcium Types.

For countries such as Canada that do not yet allow the import of Puritan's Pride Bone Care, the best calcium for osteoporosis treatment (at an attractive price) is a Calcium/Magnesium product with a second tablet that will provide a minimum of 800 IUs of vitamin D although in northern regions many experts now recommend that we take 5,000 IU of vitamin D throughout the Fall and winter months.

National customs currently prevent Puritan's Pride from shipping Bone Care to Canada, the UK, France and Germany. If there has been a change in this practice, please contact us or share your news on the Vitamins Forum.

Strontium Citrate should also be considered as a part of your bone-building program. Research has found that strontium can improve bone quantity and quality by as much as 15% within three years if combined with recommended levels of the best calcium for osteoporosis and sufficient vitamin D.

Strontium must be taken on an empty stomach preferably before going to bed. And 1,500 mg. of calcium and 800 IUs of vitamin D are essential for strontium to be effective.

It is best to introduce supplements gradually to avoid upsetting the stomach and digestive process. Research has shown that side effects disappear within a few weeks for most people.

People with severe renal impairment and other serious health conditions should consult with their doctor before using strontium.

Vitamin K

If you are taking blood thinning medication or an anticoagulant (such as Warfarin, Coumadin or Heparin) be sure to consult your doctor before increasing vitamin K in your diet or supplements.
