What is Advanced Bionutritionals Vitamin D3? 

Advanced Bionutritionals Vitamin D3 is a premium dietary supplement designed to help individuals maintain optimal levels of vitamin D, an essential nutrient that plays a crucial role in bone strength, immune function, and overall wellness.

Unlike many conventional vitamin D products, this supplement delivers a high-potency dose of 5,000 IU per tablet, aligning with modern research that supports higher daily intake for health benefits.

dvanced Bionutritionals Vitamin D3 is a reliable and convenient way to bridge the gap between your body’s needs and environmental limitations.

Whether you’re looking to support strong bones, boost your immune defenses, or enhance your overall vitality, this supplement provides a safe and effective option backed by science and trusted by health-conscious consumers.

How Does Advanced Bionutritionals Vitamin D3 Work? 

Advanced Bionutritionals Vitamin D3 works by helping your body maintain sufficient vitamin D levels, which are critical for a variety of physiological functions.

When taken regularly, this supplement supports the efficient absorption of calcium and phosphorus  two minerals essential for strong bones and teeth.

Beyond skeletal health, vitamin D3 plays a key role in modulating the immune system, reducing inflammation, and supporting muscle and nerve function.

Modern lifestyles often limit sun exposure, which is the body’s natural source of vitamin D, making supplementation necessary for many people.

This product delivers vitamin D3 in its most active and biologically effective form, which the body can easily recognize and utilize.

By maintaining proper vitamin D levels, this supplement helps enhance resilience, energy, and long-term wellness at a foundational level.

Advanced Bionutritionals Vitamin D3 Ingredients

Advanced Bionutritionals Vitamin D3 features high-absorption D3, MCT oil for better delivery, and antioxidant-rich astaxanthin for enhanced support.

Vitamin D3 (as cholecalciferol)

• Vitamin D3 is a fat-soluble vitamin that supports calcium absorption, strengthens bones, enhances immune function, and improves mood. It’s the natural form of vitamin D your body makes from sunlight and is more effective than synthetic D2.

Calcium (as calcium carbonate)

• Calcium carbonate is a common, bioavailable form of calcium that supports bone density, teeth strength, nerve function, muscle contractions, and heart rhythm. It works synergistically with vitamin D3 to prevent bone loss, osteoporosis.

Cellulose

• Cellulose is a plant-based fiber used in supplements as a binder and filler. It helps maintain the tablet’s shape and structure. While not digestible by humans, it is inert, safe, and commonly used in health products to ensure even consistency and proper dosage per tablet.

Stearic Acid

• Stearic acid is a saturated fatty acid used in supplements as a lubricant to prevent ingredients from sticking during production. It improves tablet formation and ensures even blending. Naturally found in many foods.

Croscarmellose Sodium

• Croscarmellose sodium is a super-disintegrant that helps the tablet break apart quickly after ingestion. This ensures faster dissolution and better nutrient absorption in the body. It’s widely used in pharmaceutical and dietary supplements.

Silica

• Silica (silicon dioxide) is an anti-caking agent that prevents ingredients from clumping together. It keeps the tablet mixture free-flowing during manufacturing and ensures uniform distribution of nutrients. 

Calcium Stearate

• Calcium stearate is a flow agent that prevents ingredients from sticking to equipment during tablet manufacturing. It also aids in the smooth pressing of tablets. It’s derived from calcium and stearic acid.

Rice Extract

• Rice extract is a natural additive used as a stabilizer, filler, or anti-caking agent in supplements. It helps improve the tablet’s texture and prevent moisture-related clumping. As a clean-label alternative to synthetic additives,

Cellulose Coating

• Cellulose coating is a plant-derived outer layer applied to tablets for easier swallowing, taste masking, and protection from moisture or oxidation. It helps preserve tablet integrity and ensures controlled release.
