Rebuild 180 caps by Metabolic Maintenance

Maintaining bone health is a critical factor in maintaining mobility and independence as we age. Rebuild® is a full-spectrum nutritional product designed to support bone health in patients at risk of osteoporosis. In addition to calcium and magnesium, Rebuild® contains vitamin D, vitamin K, zinc, and trace minerals important to bone health. Deficiencies of these nutrients can slow bone production or accelerate bone loss.

  • Research-based formula to support bone mineral density*
  • Contains key nutrients important for bone synthesis*
  • Full-spectrum nutritional product*

  Vitamin D is derived from lanolin.

 What is Rebuild®?

As a full-spectrum bone health supplement, Rebuild®, of course, contains the heavy hitters calcium and magnesium, but it also contains the support of vitamin D, vitamin K, zinc, and trace minerals copper, manganese, and boron, which are also important to bone health. Deficiencies of these nutrients can slow bone production or accelerate bone loss. 


How does Rebuild® Work?

Bone is living tissue that is constantly being broken down and replaced. Osteoporosis occurs when the creation of new bone doesn't keep up with the removal of old bone, resulting in decreased bone mineral density (BMD). It is associated with back pain, stooped posture, and a higher risk of fracture. Osteoporosis can affect men and women of all races but is especially prevalent in postmenopausal women of asian or caucasian decent.

The Rebuild® formula is based on a 2-year, double-blind, placebo-controlled study that measured spinal bone loss in postmenopausal women. The results showed that calcium (as calcium citrate/malate) plus trace minerals (zinc, manganese, and copper) were far more effective in maintaining BMD than calcium alone [1].

Rebuild® also contains magnesium which is essential for the absorption of calcium, acts on crystal formation in bone cells, and impacts the activity of the parathyroid hormone, which is a regulator of calcium homeostasis [2]. 60% of the body’s magnesium is stored in bone. Magnesium deficiency results in lower BMD as magnesium is pulled out of bone for other biological functions.

Vitamin D-3, or cholecalciferol, is the same form of vitamin D as the skin makes naturally in response to sunlight. It stimulates the absorption of calcium from the gut. Vitamin D status is related to BMD, and supplementation decreases bone turnover [3]. There is a high prevalence of vitamin D deficiency in modern times due to a variety of factors. Spending a majority of time indoors (lack of sun exposure), sunscreen use, living at higher latitudes, and dark skin pigmentation, are all factors that can result in low serum vitamin D levels. Rebuild® Plus contains 2000 IU vitamin D3 per 1000 mg of calcium (6 capsules) for those who need to improve vitamin D status.

Vitamins K-1 and K-2 work synergistically with vitamin D to stimulate production and activation of osteocalcin, a protein involved in bone mineralization [4]. Osteocalcin is essential for pulling calcium out of the blood and into the bone. In a recent 3-year study, low-dose vitamin K2 MK-7 treatments decreased bone loss and increased bone strength in postmenopausal women [5].


What is the Suggested Use for Rebuild®?

Supports Bone Health: Adequate calcium, vitamin D, the trace minerals described above, a well-balanced diet, and regular physical activity, may help to reduce the risk of osteoporosis.


Source Materials: Ascorbyl palmitate: ascorbic acid from corn sorbitol and palmitic acid from palm oil. Vitamin D3: lanolin from sheep’s wool. Vitamin K-1: chemical synthesis.
