insights Analysis
The Solaray Vitamin D3 + K2 product is marketed for comprehensive bone, heart, and general health support. Crucially, the listed ingredients include Vitamin K2 in its Menaquinone-7 (MK-7) form at 50mcg, which is widely recognized by nutritionists for its superior bioavailability and efficacy in directing calcium to bones and away from arteries, thus supporting cardiovascular health. Phosphorus (85mg as Calcium Phosphate) is also included, playing a role in bone mineralization. A significant observation is the discrepancy between the product name ('Vitamin D3 + K2') and the provided ingredient list, which explicitly omits Vitamin D3. If Vitamin D3 is indeed absent, the product's effectiveness for calcium absorption and overall bone health would be severely compromised, as D3 is essential for maximizing calcium uptake. However, assuming the product name accurately reflects its content (a common marketing practice for D3+K2 products), the synergy between D3 and K2 is excellent for bone density and arterial flexibility. Online reviews consistently praise the product's benefits, particularly for bone density and overall well-being, suggesting that users likely experience the synergistic effects of D3 and K2. The inclusion of MK-7 is a strong point, as this form of K2 has a longer half-life, providing sustained action. The Phosphorus content, while beneficial, is relatively low compared to daily dietary needs and is unlikely to be the primary driver of benefits. Claims regarding 'Energy,' 'Muscle Gain,' and 'Fitness' are less directly supported by a D3+K2 supplement, though general health improvements can indirectly contribute.
- Contains Vitamin K2 as Menaquinone-7 (MK-7), the most bioavailable and effective form for bone and arterial health.
- High review count indicates widespread consumer satisfaction and perceived effectiveness.
- The combination of D3 (assumed present as per name) and K2 is highly recommended by nutritionists for synergistic benefits in calcium utilization.
- Reasonable price per serving for a quality D3+K2 supplement.
- The provided ingredient list for the product omits Vitamin D3, despite 'D3' being in the product name, which could be misleading or an oversight in the data.
- The quantity of Phosphorus is relatively low (85mg) and contributes minimally to overall daily phosphorus needs.
- Claims for 'Energy,' 'Muscle Gain,' and 'Fitness' are not primary direct benefits of a D3+K2 supplement.

bolt Effectiveness for goals
Vitamin K1 is highly effective and essential for the synthesis of several proteins required for blood coagulation. It acts as a cofactor for an enzyme that modifies these proteins, enabling them to bind calcium and participate in the clotting cascade. Adequate intake of Vitamin K1 is crucial to prevent excessive bleeding.
Phosphorus is highly effective and vital for the formation and maintenance of strong bones and teeth, constituting about 85% of the body's phosphorus. It combines with calcium to form hydroxyapatite crystals, which provide the rigidity to our skeletal system. Adequate phosphorus intake is essential for skeletal integrity throughout life.
Phosphorus is exceptionally effective and critical for energy production, as it is a fundamental component of adenosine triphosphate (ATP), the body's main energy currency. ATP stores and transports energy within cells, fueling almost all metabolic processes. Without sufficient phosphorus, the body's ability to generate and utilize energy would be severely compromised.
Vitamin K is a fat-soluble vitamin essential for the synthesis of proteins required for blood coagulation, primarily in the liver. It also plays a crucial role in bone metabolism and vascular health by activating certain proteins.
Phosphorus is an essential mineral vital for the formation of strong bones and teeth, where it's found as calcium phosphate. It also plays critical roles in energy metabolism, cell membrane structure, and genetic material (DNA and RNA) synthesis.
schedule Dosage, timing & forms
Vitamin K should be taken with food, specifically a meal that includes dietary fats. This is because Vitamin K is a fat-soluble vitamin, and fat helps facilitate its absorption in the digestive tract.
Vitamin K supplements commonly contain Vitamin K1 (phylloquinone) and Vitamin K2 (menaquinones, such as MK-4 and MK-7). Recommended dosages can vary; K2 forms, particularly MK-7, often have lower daily dose recommendations due to their longer half-life and bioavailability. Always refer to product labels for specific guidance.
Vitamin K1 (phylloquinone) is often found in higher microgram dosages in supplements compared to Vitamin K2 (menaquinones), especially MK-7. This is partly due to differences in their bioavailability and how they are utilized by the body, with MK-7 having a longer half-life.
The Adequate Intake (AI) for Vitamin K is 120 micrograms (mcg) per day for adult men and 90 mcg per day for adult women. These recommendations are for total Vitamin K from food and supplements.
A common daily dosage range for Vitamin K2 (MK-7) in adult supplements often falls between 45 mcg and 180 mcg. However, specific dosages can vary based on individual needs and product formulations. It's advisable to follow the dose recommended on the product label or by a healthcare professional.
health_and_safety Safety & interactions
Vitamin K is known to interact significantly with anticoagulant medications, particularly warfarin, by reducing their effectiveness. Individuals on blood thinners should avoid Vitamin K supplements unless specifically advised by a healthcare professional. It is crucial to monitor INR levels regularly if taking both.
Yes, Vitamin K can significantly interact with anticoagulant medications like warfarin (Coumadin), reducing their effectiveness. Individuals on these medications should maintain a consistent intake of Vitamin K and consult their healthcare provider before taking supplements.
Individuals taking warfarin or other anticoagulant medications should not take Vitamin K supplements without strict medical supervision. People with certain liver conditions or those with G6PD deficiency should also exercise caution. Always consult a healthcare provider before starting supplementation.
Individuals on anticoagulant therapy, those with conditions affecting fat absorption, or people with severe liver disease should exercise caution. Newborns routinely receive a Vitamin K injection to prevent bleeding disorders. Always consult a healthcare professional for personalized advice.
Vitamin K supplements are generally well-tolerated at recommended doses. Side effects are rare but can include stomach upset, diarrhea, or allergic reactions in sensitive individuals. High doses, especially of synthetic Vitamin K (K3), are not typically used in supplements due to potential toxicity.

Vitamin K 95.0
The product features Vitamin K2 in its superior Menaquinone-7 form, which is highly effective and preferred by nutritionists for its long half-life and specific health benefits.
Phosphorus 60.0
Phosphorus is present as calcium phosphate, which is beneficial for bone health. However, the 85mg quantity is relatively small compared to daily recommended intake, making it a supportive rather than a primary source.
Goals
Heart Health 95.0
Vitamin K2 (Menaquinone-7) is highly effective in preventing calcium accumulation in arteries, a key factor in cardiovascular health. This makes the product very strong for heart and cardiovascular support.
The Menaquinone-7 form of Vitamin K2 is crucial for maintaining arterial elasticity and preventing hardening, offering robust support for overall cardiovascular function.
Bone Health 90.0
Assuming Vitamin D3 is present as per the product name, the combination with K2 (MK-7) is excellent. D3 facilitates calcium absorption, while K2 directs it to bones, preventing soft tissue calcification. Phosphorus also contributes to bone structure.
