Xtra-Cal Advanced: The Science Behind Superior Calcium Absorption

Not all calcium supplements are created equal. Herbalife's Xtra-Cal Advanced goes beyond basic calcium tablets by delivering a scientifically optimized formula designed for maximum absorption and bone health support. Let's explore the science behind what makes this supplement stand out.

What Is Xtra-Cal Advanced?

Xtra-Cal Advanced is a 90-count tablet supplement that provides essential calcium along with the critical co-nutrients your body needs to actually absorb and utilize it. Because here's the thing most people don't realize: taking calcium alone isn't enough. Without the right supporting nutrients, much of that calcium may pass right through your system unused.

Key Ingredients and the Science

Calcium (from Calcium Carbonate and Calcium Citrate): Xtra-Cal Advanced uses a dual-source calcium approach for enhanced absorption. Calcium carbonate provides a high concentration of elemental calcium, while calcium citrate is more easily absorbed — especially on an empty stomach. This combination ensures your body has access to calcium regardless of when you take it.

Vitamin D3: Often called the "sunshine vitamin," D3 is absolutely essential for calcium absorption. Without adequate vitamin D, your intestines can only absorb about 10-15% of dietary calcium. With sufficient D3, that number jumps to 30-40%. Research in the Journal of Clinical Endocrinology consistently confirms that vitamin D supplementation significantly improves calcium utilization and bone mineral density.

Magnesium: This often-overlooked mineral plays a crucial supporting role in bone health. Magnesium helps convert vitamin D into its active form, assists in calcium transport across cell membranes, and contributes to the structural development of bone tissue. Approximately 60% of your body's magnesium is stored in your bones.

Trace Minerals: Xtra-Cal Advanced includes additional trace minerals that support bone metabolism and overall skeletal health, creating a comprehensive foundation for your bones.

Why the "Advanced" Formula Matters

Here's how Xtra-Cal Advanced compares to basic calcium supplements:

• Basic calcium tablet: Provides calcium alone — absorption rate can be as low as 10-15%
• Calcium + Vitamin D: Improved absorption, but missing magnesium and trace minerals
• Xtra-Cal Advanced: Complete system — calcium from dual sources, vitamin D3, magnesium, and trace minerals working together for optimal absorption and utilization

Key Benefits

• Supports strong bones and teeth with optimized calcium delivery
• Enhanced absorption through vitamin D3 and magnesium
• Fills common nutritional gaps in calcium, vitamin D, and magnesium
• Dual-source calcium for superior bioavailability
• Easy daily supplement as part of your Herbalife nutrition program

How to Use

Take Xtra-Cal Advanced as directed on the product label, typically with a meal and a full glass of water. Taking calcium with food enhances absorption, particularly for the calcium carbonate component. For best results, use daily as part of your complete Herbalife nutrition program alongside Formula 1 shake and other core products.
