Supplément nutritionnel TheraCal®

Many bone health supplements only offer a combination of vitamin D and calcium, but it takes a team of nutrients for comprehensive bone support. TheraCal 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 TheraCal, 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.*

TheraCal is also independently tested by NSF® International for content accuracy and purity, so you know exactly what you’re getting.

TheraCal 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.

Yes, TheraCal is designed to be taken along with these medications. The most commonly recommended medications for bone health are bisphosphonates (Fosamax®, Actonel®, Boniva®, Reclast®, Zometa®) and denosumab injections (Prolia® and Xgeva®). These treatments are effective for building bone but can lower your blood calcium level. That’s why taking a calcium and vitamin D supplement (such as TheraCal) along with these medications is essential.

Although there are no expected side effects from TheraCal, taking high doses of calcium may increase the chances of constipation in some people. TheraCal also contains magnesium, which should help decrease the risk of constipation.
