Ingredients
Frequently Asked Questions
What are the main benefits of taking Calcium Bisglycinate + Vitamin D3 daily?
This synergistic formula is designed to maximize bone, tooth, and muscle health. While calcium is the fundamental building block for strong bones and teeth, Vitamin D3 acts as a critical absorption driver, enhancing your body's ability to absorb and utilize calcium effectively. It also provides vital daily support for immune system health.
Why does BULKvitamins use Calcium Bisglycinate instead of regular calcium carbonate?
Calcium Bisglycinate is a premium, chelated form of calcium where the mineral is bound to glycine amino acids. This form is significantly more bioavailable and easier to absorb than standard forms (like calcium carbonate or oxide). It is also exceptionally gentle on the stomach and does not cause the digestive discomfort or bloating often associated with cheaper calcium supplements.
How long will one pouch of Calcium + Vitamin D3 last?
Each pouch contains 360 capsules. Based on the recommended daily serving of two capsules (delivering 300 mg of elemental Calcium and 2000 IU of Vitamin D3), a single pouch provides a full 180-day (6-month) supply of premium bone support.
Is this Calcium + Vitamin D3 supplement lab-tested?
Yes. Purity, quality, and complete transparency are fundamental to BULKvitamins. Like all our products, this Calcium + D3 supplement undergoes rigorous independent laboratory testing to verify exact potency and ensure it is entirely free from heavy metals, contaminants, or unnecessary binders and fillers.
When is the best time to take Calcium + D3 capsules?
Because Vitamin D3 is a fat-soluble nutrient, it is best absorbed when taken with a meal containing healthy fats. We recommend taking your daily serving (2 capsules) in the morning or evening with food. This optimizes absorption rates and ensures consistent, daily bone and immune support.
