Plant Sourced Calcium Supplements And Organics For Osteoporosis Treatment

Calcium supplements made from plants and organics are more expensive than generic supplements. Does research support the higher prices?


Approximate Cost: $330-$360 year ($1/day)

Some research suggests that calcium supplements derived from plant products are more easily absorbed than calcium derived from limestone. Both generic supplements and plant based calcium supplements offer a blend of calcium, magnesium, vitamin D, vitamin K and boron in addition to other minerals that are important for osteoporosis prevention.

Even if our bone-building program centers around generic calcium supplements, it may be wise to have a Green Supplement available for those busy days when we know our diet has been inadequate. Costs typically range from $1.00-$1.50 a day compared to the 17 cent daily cost of a generic osteoporosis treatment program.

Two of the better known Green Supplement tablets are Genuine Health Bone Builder and AlgaeCal. Neither company has met the scientific research standards needed to support their claims of superiority... although both have conducted some research on their products.

Genuine Health Bone Builder

The manufacturer of Genuine Health Bone Builder claims the calcium in its product (calcium-bisglycinate, formate and citrate malate) can be absorbed at a rate of 78%, which would make it three times more effective than calcium carbonate and almost twice as effective as CCM. Three tablets are required to gain the values provided by one scoop of powder.

Annual Cost: $600 CDN (1 scoop daily) or $326 US (3 tablets daily)

  • Calcium: 500 mg.
  • Vitamin D3: 800 IUs
  • Magnesium: 300 mg
  • Boron: 3 mg
  • Vitamin K: unspecified

Greens+ Bone Builder combines a bone-building formula with its regular Greens+ powder drink. This is a high quality supplement that is especially valuable when our diet or nutrition has not been optimal. This well balanced supplement comes in blackberry and vanilla flavours and is best taken before bed to take advantage of the bone building that occurs overnight. One full scoop is required to attain the values listed above.

AlgaeCal Plus

Annual Cost: $360 US (3 tablets daily)

  • Calcium: 540 mg.
  • Vitamin D3: 1,200 IUs
  • Magnesium: 263 mg
  • Vitamin K2: 75 mcg
  • Boron: 2.25 mg.

Three tablets are required to get the above values. AlgaeCal claims a 75% absorption rate for its product based on a 2008 clinical trial involving 176 people over a six month period. The study was not randomized and was single blinded.

Note: Three Green Supplement tablets will supply most of the Vitamin D, Vitamin K and magnesium but only one third of the daily calcium that is recommended. Generic supplements can provide additional calcium at a competitive price.

Puritan's Pride Bone Care provides the recommended levels of calcium in two pills for less than $30 a year.
