    FAQs
    How is Prosteon different from other bone health supplements?
    Many bone health supplements only offer a combination of vitamin D and calcium, but it takes a team of nutrients for comprehensive bone support. Prosteon is formulated with the highest quality ingredients for optimal bioavailability, and each nutrient has a specific purpose to support bone health.
    • Calcium provides strength and structure within your bones. The particular form of calcium in Prosteon, calcium citrate, offers superior bioavailability and is well-absorbed, even in those taking an acid-reducing medication.
    • Vitamin D3 promotes calcium absorption and supports healthy vitamin D levels.
    • Magnesium helps activate vitamin D and plays an important role in bone formation.
    • Vitamin K2 helps vitamin D deposit calcium in the bone, and not in the arteries. These two nutrients work together to support optimal bone and heart health.
    • Boron is a key trace mineral necessary for calcium and vitamin D metabolism.
    Prosteon is also independently tested by NSF® International for content accuracy and purity, so you know exactly what you’re getting.
    Who can benefit from Prosteon?
    The Canadian Urological Association (CUA) recommends all men receiving ADT take a calcium and vitamin D supplement. While Prosteon was designed to promote bone health in men who are undergoing ADT, it can be taken by anyone seeking a supplement to support their bone health.
    What if I have a hard time swallowing Prosteon?
    Prosteon tablets are scored to make it easy for you to cut the tablet in half. You may also crush the tablet and mix it with applesauce, yogurt, or another preferred food. Cutting or crushing the tablet will not decrease the effectiveness of the nutrients.
    I'm taking a medication for bone health. Do I also need to take Prosteon?
    Yes, Prosteon is designed to be taken along with these medications. The most recommended medications for bone health are bisphosphonates (Actonel®, Boniva®, and Reclast®) and denosumab injections (Prolia® and Xgeva®). These treatments are effective for building bone but can lower your blood calcium levels. That’s why taking a calcium and vitamin D supplement (such as Prosteon) along with these medications is essential.
    How long should I take Prosteon?
    Prosteon is meant for daily, long-term use. Talk to your doctor about how long you should take Prosteon.
    Can women take Prosteon?
    Yes. Women trying to maintain bone health can benefit from Prosteon.
    Are there any side effects from Prosteon?
    Although there are no expected side effects from Prosteon, taking high doses of calcium may increase the chances of constipation in some people. Prosteon also contains magnesium, which should help decrease the risk of constipation.
    Can I take other nutritional supplements with Prosteon?
    Yes. You can continue to take most other nutritional supplements along with Prosteon.
    Does Prosteon interact with any prescription medications?
    The list below includes some of the more common potential interactions. This is not meant to be a comprehensive list or take the place of advice from your healthcare provider. As with any dietary supplement, discuss with your pharmacist and/or healthcare team to determine whether Prosteon can be taken along with your medications.
