Calcium with Vitamins D3 and K2 30c by Dr. Mercola – Bone Health Calcium Supplement
Calcium with Vitamins D3 and K2 capsules by Dr. Mercola combine eggshell-derived calcium carbonate with cholecalciferol and chickpea-derived vitamin K2. This 30-capsule formula pairs a mineral building block with two vitamins involved in normal calcium use, providing nutritional support for bone health in an adult supplement.
Each capsule supplies 180 mg calcium, 125 mcg (5,000 IU) vitamin D3, and 180 mcg vitamin K2. The calcium contributes to total daily intake rather than replacing calcium-rich foods. The concentrated vitamin D amount makes practitioner guidance important when deciding whether this combination fits alongside a multivitamin or separate vitamin D supplement.
Key Calcium with Vitamins D3 and K2 30c Benefits
- Supplies calcium for the mineral framework that gives bones and teeth their structure, complementing calcium obtained through everyday food choices.
- Supports normal calcium absorption through vitamin D3, helping the body use this essential mineral as part of balanced nutrition.
- Provides vitamin K2 for activation of proteins involved in normal bone metabolism, alongside calcium and vitamin D.
How Calcium with Vitamins D3 and K2 30c Works
Bone is living tissue that continually renews itself. Calcium becomes part of its mineral framework, while vitamin D helps regulate how calcium moves from the intestine into the body. Vitamin K supports the activation of specific proteins involved in this ongoing mineral-handling process. These nutrients have complementary roles, not interchangeable ones.
The calcium carbonate form is best taken with food, consistent with this formula's meal-time directions. Its contribution to bone mineralization depends on adequate overall nutrition; a capsule does not replace dietary protein, other minerals, or regular weight-bearing activity.
Key Functional Ingredients Include:
- Calcium: Supplies mineral material for bones and teeth. The body also uses calcium to transmit nerve signals and allow muscles to contract. This eggshell-derived source contributes calcium to the same regulated mineral pool supplied by foods.
- Vitamin D3: After activation in the body, vitamin D helps intestinal cells absorb calcium and supports normal calcium balance. Cholecalciferol provides this nutrient in the D3 form, complementing the calcium supplied by the capsule and meals.
- Vitamin K2: Helps activate vitamin K-dependent proteins, including osteocalcin in bone. This activation allows those proteins to bind calcium as part of normal bone metabolism. The formula provides menaquinone-7 from chickpea; vitamin K also participates in normal blood clotting.
Calcium with Vitamins D3 and K2 30c Is Formulated For
- Adults seeking a combined calcium, D3, and K2 capsule within a practitioner-guided nutrition plan.
- Adults comparing their dietary calcium intake with supplemental calcium while reviewing total vitamin D intake.

IF YOU ARE NURSING, PREGNANT, HAVE A BLOOD COAGULATION OR OTHER MEDICAL CONDITION, OR ARE TAKING MEDICATION SUCH AS ANTICOAGULANTS, CONSULT YOUR PHYSICIAN BEFORE TAKING THIS PRODUCT.
Additional precautions: Do not use with an egg allergy. Each capsule's 125 mcg (5,000 IU) vitamin D exceeds the usual adult daily upper limit of 100 mcg (4,000 IU); use only with healthcare supervision and review other vitamin D sources. Excess vitamin D can raise blood calcium and cause nausea, weakness, excessive thirst or urination, and kidney problems. Calcium carbonate can cause gas, bloating, or constipation. Vitamin K can interfere with warfarin and similar anticoagulants. Ask a pharmacist about calcium interactions with levothyroxine, dolutegravir, and certain antibiotics, and about vitamin D with thiazide diuretics or statins. Lithium with calcium can raise blood calcium. Orlistat, steroids, bile acid sequestrants, and prolonged antibiotic use can affect vitamin D or K status; review all medicines before use. Discuss kidney disease or stomach conditions with your physician before taking calcium carbonate.
Frequently Asked Questions About Calcium with Vitamins D3 and K2 30c
What are the benefits of Calcium with Vitamins D3 and K2 30c?
This Dr. Mercola formula brings together three nutrients with complementary roles in bone nutrition. Calcium supplies mineral material for bones and teeth, vitamin D3 supports intestinal calcium absorption, and vitamin K2 helps activate proteins involved in bone metabolism. Each capsule contains 180 mg calcium, 125 mcg (5,000 IU) vitamin D3, and 180 mcg vitamin K2. Its vitamin D strength warrants practitioner guidance rather than automatically adding it to another vitamin D product.
Who should take Calcium with Vitamins D3 and K2 30c?
The label directions are for adults considering combined calcium, vitamin D3, and vitamin K2 supplementation. A practitioner should review whether the 5,000 IU vitamin D amount suits your needs and existing supplements. This is not an egg-free choice: the calcium comes from eggshell and the label declares egg. Pregnant or nursing adults, people with a blood coagulation or other medical condition, and anyone taking medication should consult a physician before use, as the label instructs.
Are there any side effects of taking Calcium with Vitamins D3 and K2 30c?
Calcium carbonate can cause gas, bloating, or constipation. Vitamin K can interfere with warfarin; excessive vitamin D can raise blood calcium. This 5,000 IU dose exceeds the usual adult upper limit and needs healthcare supervision. Contains egg. KEEP OUT OF REACH OF CHILDREN. DO NOT USE IF SAFETY SEAL IS BROKEN. IF YOU ARE NURSING, PREGNANT, HAVE A BLOOD COAGULATION OR OTHER MEDICAL CONDITION, OR ARE TAKING MEDICATION SUCH AS ANTICOAGULANTS, CONSULT YOUR PHYSICIAN BEFORE TAKING THIS PRODUCT.
How does Calcium with Vitamins D3 and K2 30c support overall health?
Calcium supports more than the skeleton: it also participates in normal nerve signaling and muscle contraction. Vitamin D helps the body absorb and regulate calcium, while vitamin K contributes to normal blood clotting and activation of bone proteins. This combination supplies those nutrients in one capsule, but overall nutrition still matters. The 180 mg calcium contribution should be considered alongside calcium-rich foods, and the concentrated vitamin D amount should be reviewed with your healthcare practitioner.
