The Solaray Vitamin D3 + K2 product is designed to support bone, heart, and general health. Its core strength lies in its inclusion of Vitamin K2 as Menaquinone-7 (MK-7) at 50mcg, a form widely recognized by nutritionists for superior absorption and its crucial role in directing calcium to bones while preventing its accumulation in arteries. Phosphorus (85mg as Calcium Phosphate) is also included, providing foundational support for bone matrix formation. Similar to its smaller variant, a notable point is the divergence between the product's name ('Vitamin D3 + K2') and the provided ingredient list, which does not explicitly mention Vitamin D3. If D3 were genuinely absent, the product's efficacy in facilitating calcium absorption and maximizing bone health benefits would be significantly limited. However, assuming D3 is indeed present (as implied by its name and typical market formulations), the synergistic action of D3 and K2 is paramount for robust bone density and arterial health. The larger 120-serving size of this particular variant offers a better price per serving (24 cents vs. 26 cents for the 60-serving bottle), enhancing its value proposition. Positive online reviews frequently highlight the product's benefits for overall vitality and bone strength, confirming its positive reception among users. While Phosphorus contributes to bone health, its relatively small quantity means its impact is supplementary rather than primary. The product's contribution to 'Energy,' 'Muscle Gain,' or 'Fitness' is indirect and less pronounced than its primary bone and cardiovascular benefits.
