NOW Bone Strength offers a well-rounded and highly bioavailable formulation for comprehensive bone health, leveraging MCHA calcium, synergistic vitamins D3 and K2, and essential trace minerals. It represents a strong value for those prioritizing skeletal support, though some listed secondary goals are less directly addressed.
NOW Bone Strength is a comprehensive supplement designed primarily for bone health, featuring a robust blend of key minerals and vitamins. Its most significant strength lies in its use of Microcrystalline Hydroxyapatite (MCHA) as a primary calcium and phosphorus source, which is highly bioavailable and mirrors the natural bone matrix. The formula is further enhanced with synergistic nutrients crucial for bone metabolism, including Vitamin D3 for calcium absorption, Vitamin K2 (Menaquinone-4) for calcium utilization and preventing arterial calcification, and a blend of Magnesium forms for bone density and enzyme function. Essential trace minerals like Boron, Zinc, and Manganese are also included in well-absorbed chelated forms, contributing to bone formation and overall mineral balance. However, the listed quantity of Copper as 0mg is a notable omission or error, as copper is vital for collagen cross-linking in bones. While the product lists numerous broader goals like energy, brain health, and immunity, its formulation is distinctly tailored towards skeletal support, making these other benefits more ancillary and not as strongly supported by dedicated ingredient profiles.
- Contains highly bioavailable Microcrystalline Hydroxyapatite (MCHA) for comprehensive bone mineral support, including phosphorus.
- Includes crucial co-factors like Vitamin D3 and Vitamin K2 (MK-4) essential for proper calcium utilization and directing calcium to bones.
- Features well-absorbed chelated forms of key trace minerals such as Boron, Zinc, and Manganese, vital for bone matrix formation.
- Offered at a competitive price per serving for its comprehensive bone health profile.
- Backed by a reputable brand (NOW) and positive customer reviews.
- The listed 0mg quantity for copper is a significant concern, as copper is an essential trace mineral important for bone health and collagen formation.
- While listing numerous general health goals (e.g., Energy, Brain Health, Cognitive Support), the formulation is primarily optimized for bone health, meaning these other goals might not receive optimal or targeted support.
- Requires a serving size of 4 capsules, which might be inconvenient for some users.
- The Vitamin D3 dose (16mcg/640 IU) is supportive but lower than some alternative bone health supplements that provide 1000-5000 IU.
- Contains Vitamin K, which can interact with anticoagulant medications like Warfarin; individuals on such medication should consult a healthcare professional.
- The Microcrystalline Hydroxyapatite (MCHA) is derived from bovine bone, making this product unsuitable for strict vegetarians or vegans.

Categories
Calcium 90.0
The use of Microcrystalline Hydroxyapatite (MCHA) as a calcium source is excellent due to its high bioavailability and natural co-presence of phosphorus and other trace minerals, making it highly effective for bone mineralization. The dosage of 667mg is also substantial for bone health.
Vitamin K 85.0
The product contains Vitamin K2 (Menaquinone-4) at a good dose (67mcg), which is crucial for directing calcium to bones and away from arteries, directly supporting the primary bone health goal.
Phosphorus 85.0
Phosphorus is naturally present in the Microcrystalline Hydroxyapatite (MCHA) form of calcium (287mg), providing an essential mineral directly involved in bone structure and density in a highly integrated and bioavailable manner.
Goals
Bone Health 95.0
This product is exceptionally well-formulated for bone health, featuring highly bioavailable MCHA (Calcium and Phosphorus), optimal forms of Magnesium, and essential co-factors like Vitamin D3, Vitamin K2 (MK-4), Boron, and Manganese, all critical for bone density and mineralization.
Joint Health 75.0
With good amounts of Calcium, Magnesium, and Vitamin C, which contribute to collagen formation and overall connective tissue health, this product offers decent support for joint health as a secondary benefit. Horsetail, a source of silica, also plays a role in connective tissue integrity.
General Health 70.0
As a multi-mineral with essential vitamins D, K, C, and B1, it contributes to overall well-being and addresses common mineral deficiencies, supporting various bodily functions important for general health. However, it is not a complete multivitamin providing all daily micronutrient needs.
