Prosteon

My father has been taking Prosteon, a nutitional supplement.  His urologist put him on this.  Besides enriching his urine, is there any clinical evidence that it does any good?  He has been getting Lupron.

Has he been diagnosed with prostate cancer? If so, what does his oncologist say?  In other words, get a second opinion and better yet move on by having an oncologist, preferably associated with a teaching university. Maybe check NCI comprehensive cancer center nearest you.

Prosteon is just a multivitamin with minerals.  There is no clinical evidence that it does anything for prostate cancer.

Prosteon is aimed at men on ADT & doesn't claim to do more than support bone health.  For all I know, it might be a generic formula against osteoporosis.

...

Daily dose of 4 tablets provides 6 nutritional components:

Calcium 1000 mg (as calcium citrate)

Vitamin D3 2,000 IU (cholecalciferol)

Vitamin K1 100 mcg (as phytonadione)

Magnesium 200 mg (as magnesium oxide)

Strontium 100 mg (as strontium citrate)

Boron 3 mg (as boron glycinate)

...

My comments:

- K1 has a short half-life.  K2 is far better:

& MK-7 actually has anti-PCa properties.

- Throwing calcium at bone loss doesn't address the problem.  If calcium intake is already adequate, adding another 1,000 mg might lead to unsafe levels, since a number of studies have associated calcium above 1,000 mg with an increased risk of aggressive disease.  The probable reason is that the kidneys will not convert vitamin D to the active hormonal form (1,25-D), when they are busy ditching excess calcium.  And, ironically, excess calcium suppresses the mechanism that would build bone.

- Strontium displaces calcium.  It is not an essential element, but I know that some swear by it.

- Boron is a good supplement against PCa, but 6 mg is the minimum I would take.

- 2,000 IU vitamin D3 is unlikely to lead to optimal calcidiol (25-D) levels.

- one reason for bone loss in men on ADT is estradiol [E2] falling below ~12 pg/mL.  E2 should be monitored.  A low-dose Vivelle-Dot E2 patch (probably not every day) can keep E2 in the 12-20 pg/mL range.

I like that Prosteon contains Calcium, Vit. D3, Vit. K, Magnesium and Boron, but i dont like that it also contains Strontium....I read some where that Stontium should not be taken at the same time with Calcium.... It prevents the absorption of calcium.

Check out invitehealth.com  they have a great bone food powder with all the above and no Strontium. They have a separate suppliment of only Strontium you can take at a different time...
