Adequate calcium with vitamin D as part of a healthful diet throughout life, along with physical activity, may reduce the risk of osteoporosis in later life.
For younger adults building strong bones for life.*
AdvaCAL™ 1000 delivers 1,000 mg of ionic AAACa™ Calcium and 1,000 IU of Vitamin D₃ daily—formulated to help lay a solid foundation for bone strength during peak bone-building years. Extra-small capsules make daily support easy and comfortable to take.*
Your 20s and 30s are the most important years for building strong, healthy bones. AdvaCAL™ 1000 is designed to help young adults maximize their bone-building potential, delivering 1,000 mg of highly absorbable AAACa™ Calcium and 1,000 IU of Vitamin D₃. With its extra-small capsules and the addition of HAI™ for enhanced absorption, it’s the ideal foundational calcium for those seeking lifelong skeletal strength.*
Not all calcium is created equal—and not all of it is absorbed well. Most supplements use calcium carbonate or citrate, which rely on stomach acid for digestion. AdvaCAL™ is different.
It begins with oyster shell calcium, which undergoes a superheating process at over 800°C to transform it into a more bioavailable form—calcium oxide and calcium hydroxide. This transformation creates AAACa, or Active Absorbable Algal Calcium, a unique form of ionic calcium designed for better absorption and usability by the body.*
To further enhance bioavailability, AdvaCAL™ also includes HAI™, a specialized amino acid extract from Japanese sea algae. HAI works by helping transport calcium through the intestinal lining, promoting better absorption directly into the bloodstream.*
The result: a highly absorbable calcium supplement your body can actually use—especially important for building strong bones during your most active years.*
Take 3 capsules in the morning and 3 capsules at bedtime, preferably with food.
Each full daily serving provides:
→ 1,000 mg AAACa Calcium
→ 1,000 IU Vitamin D₃
→ < 1 mg HAI
Each daily serving of AdvaCAL™ 1000 contains 1,000 mg of calcium (as calcium hydroxide and calcium oxide), 1,000 IU of Vitamin D₃, and <1 mg of HAI™, an amino acid extract derived from Japanese sea algae. These ingredients work together to deliver highly bioavailable calcium and support healthy bone metabolism.*
Vitamin D₃ is essential for helping your body absorb calcium effectively. Without it, calcium may not be transported efficiently into the bones. AdvaCAL™ 1000 includes 1,000 IU of D₃ to ensure calcium is guided to where it’s needed most—your bones.*
Yes. While bone health concerns are often associated with women, men also experience gradual bone loss with age—especially after 50. Getting enough calcium and vitamin D is essential for both men and women to maintain strong bones and reduce the risk of fractures later in life.*
It’s best to take 3 capsules in the morning and 3 at bedtime with meals. This divided dosage helps optimize calcium absorption throughout the day and night, especially during nighttime bone turnover.*
AdvaCAL™ 1000 is ideal for young adults or anyone seeking to maintain strong bones preventatively. If you’re over 40 or want more comprehensive support, AdvaCAL™ Ultra includes magnesium, vitamin K2, and trace minerals. If you’re postmenopausal or at higher risk of bone loss, AdvaCAL™ Intensive offers higher daily amounts of calcium and vitamin D₃ for intensive support.*
