Did you know that Vitamin D deficiency is common? It could be from not spending enough time in the sun, low hormone levels, being overweight, or certain medications. But do not fret! Vitamin D Ultra 10K provides your body with the Vitamin D it needs as well as a boost of Vitamin K. This formula was made to provide you with the Vitamin D you need as well as making it easy for your body to breakdown and use for functioning. If Vitamin D Ultra 10K is a higher dose than you need, Vitamin D Synergy (2,000 IU) or Vitamin D Supreme (5,000 IU) from Designs for Health are lower dosage options and also contain the important combination of Vitamin D3 and Vitamin K. Vitamin D Synergy, versus Vitamin D Ultra 10K, should be considered for maintenance of optimal blood levels of Vitamin D3 and Vitamin K for long-term supplementation in people without a critical Vitamin D deficiency. This bottle comes with 60 capsules.
