What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.


Fosteum is a non-prescription medical food that your healthcare provider may have you take if you need to increase bone mineral density because of degenerative bone diseases like osteopenia and osteoporosis. Despite its status as a medical food, it still must be prescribed.

Fosteum is generally used in women that have experienced menopause. After menopause, the bones begin to lose their strength at an increasing rate. This can lead to the development of osteopenia or osteoporosis. Once these conditions develop, a person is at a much higher risk for a large bone fracture, including the hip and spine.

Normally, there are cells in the bone that constantly break down bone and other cells that rebuild it. Fosteum works by increasing the amount of bone-building and reducing the amount of bone breakdown. One of the active ingredients, Genistein, works by reversing the effects of estrogen loss after menopause.


The standard Fosteum dosage is to take one Fosteum tablet by mouth every 12 hours.

Fosteum can be taken with or without food.


The active ingredients in fosteum are Genistein, Citrated Zinc Bisglycinate, and Cholecalciferol (vitamin D3).

The inactive ingredients include

  • Dicalcium malate
  • Magnesium oxide
