Non-Acidic 24-Hour Support 1000 mg Non-Acidic Ester C 5000 IU Vitamin D3 Patented Ester-C Unique Gentle Form of Vitamin C Once Daily Dietary Supplement Non-GMO Suitable for Vegetarians Today Vitamin D is considered more important than ever. Vitamin D3, a more potent and bio-available form compared to Vitamin D2, plays an active role in the absorption of Calcium and Phosphorus, the building blocks of bone health. With concern about the damage of long term sun exposure, many of us are not getting the Vitamin D we need from natural sunlight. Non-Acidic Ester-C with D3 Bone & Immune Health Complex combines the 24-hour immune support of pH-neutral Ester-C Vitamin C with high-potency (5,000 IU) Vitamin D3 in a once daily formula. Ester-C with D3 delivers over 10X the recommended daily level of Vitamin D, in a form that closely mirrors the Vitamin D our body naturally produces. The body produces Vitamin D directly from sunlight, and uses it to better absorb Calcium. If you're not getting enough Vitamin D every day, you may not be able to adequately absorb Calcium from the foods you eat. Your body will then seek our other sources of Calcium including the bone itself, which can impact bone density. Ester-C with D3 Bone & Immune Health Complex provides a smart, healthy way to receive the benefits of a high-potency Vitamin D3 supplement along with the 24-hour immune support of Ester-C. The Ester-C with D3 Bone & Immune Health Complex Difference: The nutritional advantage of a dual-action formula in a once daily complex 24-hour immune support of pH-neutral, non-acidic Ester-C High-potency 5,000 IU delivery of Vitamin D3, a more potent and bio-available form compared to Vitamin D2 Adequate Vitamin D intake has been shown to help maintain healthy bone density measures.American Health
