May is Women’s Health Month, a reminder that women have distinctive and specific health needs to consider. This is especially true as women get older and begin experiencing hormonal changes, the effects of skeletal aging or the increasing risk of cardiovascular problems.
Dee Cee Laboratories’ Vitamins D3 + K2 supplement provides doctors of chiropractic a clinically supported way to enhance female patient care. The synergy of these essential nutrients combined offers women a two-vitamins-in-one boost to heart and bone health.
Women, aging and decreasing estrogen
After women enter menopause, they typically face a decline in estrogen levels, which leads to increased bone resorption and decreased bone mineral density (BMD), heightening women’s risk of osteoporosis. The lower estrogen levels also impact the genitourinary tract, causing vaginal dryness and a change in vaginal pH, which negatively affect sexual functioning and leave women more prone to developing urinary tract infections (UTIs).
Vitamin D3, especially when combined with K2, helps restore balance.
Calcium absorption
First, vitamin D3 facilitates calcium absorption in the intestines and promotes calcium’s incorporation into the bone matrix, helping counteract bone loss and maintain BMD.
A research review in 2023, published in the journal Diseases, analyzed the outcome of 26 relevant clinical trials and concluded vitamin D3 supplementation, paired with supplemental calcium, significantly improved BMD in postmenopausal women.
Vitamin K2 supplementation has also been shown to improve bone mineral density in this age group, particularly in the waist and hips. A review in Bone and Joint Research further revealed K2 appears to work not by increasing the amount of osteocalcin, a calcium-binding protein hormone, but by helping facilitate its carboxylation, a chemical reaction critical to bone strength and health.
Vitamin K2 activates osteocalcin and matrix Gla protein (MGP), which are vital for directing calcium to bones and preventing arterial calcification. A 2025 study in Nutrients found one-year supplementation with menaquinone-7 improved vascular stiffness and lowered blood pressure in postmenopausal women.
Other effects of menopause
As for genitourinary symptoms, a 2023 study in Nutrients showed supplementing with D3 positively affected vaginal pH, tissue moisture levels, sexual functioning and UTI frequency. The urogenital tract contains vitamin D receptors, and adequate vitamin D levels are associated with improved epithelial integrity.
Vitamin D3 can help bolster mood, too. D deficiency has been linked to depressive symptoms. A meta-analysis of randomized trials found vitamin D supplementation may lead to significant improvement in depressive symptoms, particularly with doses around 8,000 IU per day.
Put D3 + K2 together for even greater health benefits
Choosing a supplement that combines vitamins D3 and K2 ensures efficient calcium utilization, enhancing your female patients’ bone health while preventing blood vessel calcification. A review of clinical studies, published in Nutrients in 2024, indicates this combination positively affects cardiovascular and bone health in postmenopausal women.
Final thoughts: Dee Cee Laboratories’ Vitamins D3 + K2 supplement is your clinical ally
Maintaining optimal levels of both vitamins will have a positive impact on overall health and quality of life, so encourage your female patients to try a combination formula that conveniently delivers D3 and K2 together.
Dee Cee’s supplement offers 5,000 IU of vitamin D3 and 90 mcg of K2 as MK-7 per serving, amounts which align with clinical research dosages. This formulation supports bone density maintenance and cardiovascular health, making it a valuable addition to the care plan for female patients, especially those in postmenopausal stages of life.
For doctors of chiropractic committed to improving women’s health outcomes, Dee Cee Laboratories’ Vitamins D3 + K2 supplement provides a research-backed solution.
