When patients present with significantly low 25-OH vitamin D levels, we reach for this higher-potency option. It allows us to efficiently replete deficiency under clinical guidance without requiring patients to take multiple capsules of a lower-dose product.
"When I see lab work showing significantly low vitamin D, I don't want patients taking multiple capsules of a low-dose product to catch up. This higher-potency option lets us replete deficiency efficiently and get levels where they need to be, faster." – Staff Pharmacist

Microcrystalline cellulose, capsule (hypromellose and water), vegetable stearic acid, vegetable magnesium stearate, and silica.
Swallow one capsule daily with water, preferably at mealtime, or as directed by your healthcare professional. Taking this supplement with a meal that contains dietary fat supports absorption of both fat-soluble vitamins.
10,000 IU is a therapeutic dose typically used under provider supervision to correct a documented vitamin D deficiency, not as a general daily maintenance supplement. If you’re using this formula, it’s worth having your serum 25-hydroxyvitamin D levels monitored periodically so your provider can adjust the dose as your levels normalize. Our pharmacists are available to answer questions about testing and dose management at (480) 887-0244.
Consult your healthcare professional before use. This product contains vitamin K2, which can interact with blood thinners, including warfarin. If you’re taking any anticoagulant medication, this conversation with your provider is essential before starting. Individuals taking other medications should also discuss potential interactions with their healthcare professional. Do not use if the tamper seal is damaged.
Superior D3 10,000 IU with K2 addresses two interconnected nutritional needs with a single, well-formulated capsule.
Vitamin D3 supports calcium absorption from the gut, which is the foundational step in maintaining bone density. Vitamin K2 as MK-7 activates osteocalcin, the protein responsible for binding calcium into the bone mineral matrix. Research has shown that MK-7 at doses of 45–90 mcg per day increases osteocalcin carboxylation and improves the ratio of carboxylated to uncarboxylated osteocalcin, a marker associated with bone health. A three-year study of postmenopausal women found that low-dose MK-7 supplementation helped decrease bone loss compared to placebo. Adequate vitamin D throughout life, as part of a well-balanced diet, may also reduce the risk of osteoporosis.*
The cardiovascular benefit of vitamin K2 comes from its role in activating matrix GLA protein (MGP), which inhibits calcium from depositing in arterial walls and soft tissue. Research has demonstrated that higher long-term intake of long-chain menaquinones, including MK-7, is inversely associated with coronary calcification. Pairing K2 with high-dose D3 is clinically relevant because supplemental vitamin D increases calcium absorption, and K2 helps ensure that calcium is directed toward bone rather than arterial tissue.*
Not all vitamin K2 supplements are equivalent. MK-7 has a longer molecular side chain than MK-4, which makes it more hydrophobic and better transported through the body via plasma lipoproteins. Compared to K1, MK-7 has a six times longer half-life and a seven to eight times higher dose-response level. This superior bioavailability means MK-7 reaches extrahepatic tissues, including bones and arterial walls, where its activity is most needed. The K2 in this formula is Vitamk7â„¢, a naturally derived, solvent-free MK-7 obtained through a biofermentation process.*
10,000 IU of D3 is a therapeutic dose intended for supervised correction of vitamin D deficiency. Vitamin D3 (cholecalciferol) is the form your skin produces naturally and has been shown to be approximately 87% more potent than D2 at raising and maintaining serum vitamin D levels. At this dose, regular monitoring of serum 25-hydroxyvitamin D is appropriate to ensure levels reach the target range without exceeding it.*
When you buy a supplement from Val Vista Pharmacy, you’re buying from a licensed, practicing pharmacy, not a marketplace, not a fulfillment warehouse. That distinction matters for a few reasons.
Every supplement we carry has been evaluated by our pharmacists for ingredient quality, formulation rationale, and manufacturer standards.

Most supplement retailers can’t answer a clinical question about their products. We can. A 10,000 IU D3 formula is one where a conversation with a pharmacist is genuinely valuable, whether you have questions about dosing, monitoring, or interactions with other medications.
