Vitamin D3 + K2 | 5000 IU of D3 (as cholecalciferol) for Optimal Calcium Absorption | 100 mcg of K2 (as menaquinone-7) for Circulatory Health | Supports Bone & Immune Health | 60 Vegetarian Capsules

I use this while nursing and pregnant to keep up my vitamins and support my bone health. Will continue after baby as well.

Vitamin Basics & Tips

Vitamin D plays a crucial role in maternal and fetal health during pregnancy. It enhances calcium absorption, directly supporting bone mineralization critical for both the developing baby's skeletal system and the mother's bone density preservation. Nursing mothers particularly benefit from maintaining adequate Vitamin D levels, as breastmilk composition depends on maternal nutrient reserves.

Daily sunlight exposure (10-30 minutes) helps natural Vitamin D synthesis, though geographical location and skin pigmentation affect production efficiency. Dietary sources like fatty fish, fortified dairy products, and egg yolks provide supplementary amounts. However, many prenatal guidelines recommend 600-800 IU daily Vitamin D supplementation due to modern lifestyle limitations and increased nutritional demands during gestation.

Emerging research suggests Vitamin D3 (cholecalciferol) demonstrates better bioavailability compared to D2 (ergocalciferol), making it the preferred form for supplements. Adequate levels may also support immune function and mood regulation in perinatal periods. Regular blood level monitoring helps personalize dosage requirements, especially for women with limited sun exposure or darker skin tones at higher deficiency risk.
