A well-dosed Vitamin D and A supplement that also contains a significant amount of Vitamin K, but the specific form of Vitamin K is not disclosed, limiting its assessment for targeted bone and cardiovascular benefits.
Terra Origin's A-D-K Essential Vitamins provides a potent dose of Vitamin D3 (5000 IU), which is highly beneficial for calcium absorption and immune function. The inclusion of Vitamin A (Retinyl Palmitate, 5000 IU) also supports bone growth and immune health. The product claims 1000 mcg of Vitamin K, but critically, it does not specify whether this is K1 (phylloquinone) or K2 (menaquinone) or a blend of both. For bone and cardiovascular health, Vitamin K2 (especially MK-7) is paramount. Without this clarity, the efficacy for the stated goals, particularly 'Bone Health' and 'Cardiovascular Support,' is questionable, as K1 has a much less direct role in directing calcium. Nutritionists often emphasize K2 for these specific benefits. While online reviews are generally positive, they don't clarify the K form, leaving a crucial gap in understanding its full potential.
- Contains a potent dose of Vitamin D3 (5000 IU), crucial for calcium absorption and immune support.
- Includes Vitamin A, which supports bone health and immune function.
- Offers a synergistic combination of fat-soluble vitamins.
- The specific form of Vitamin K (K1, MK-4, or MK-7) is not specified, which is a significant drawback for assessing its effectiveness for bone and cardiovascular health.
- The high dose of Vitamin A may be a concern for some if combined with other Vitamin A sources, although generally safe at this level.
- Higher price per serving compared to single-nutrient supplements.
- The high dose of Vitamin D3 (5000 IU) may not be suitable for all individuals and should be discussed with a healthcare professional, especially if existing D levels are not known.
- If the unspecified Vitamin K is largely K1, individuals on blood thinners should exercise caution and consult a doctor.

Categories
Vitamin K 65.0
While a substantial amount of Vitamin K is present, the lack of transparency regarding its specific form (K1, MK-4, or MK-7) significantly reduces its score within the Vitamin K collection, as K2 is more highly valued for the common goals.
Goals
Bone Health 75.0
The strong Vitamin D3 dose synergizes with Vitamin K and A for bone health, but the ambiguity of the Vitamin K form prevents a higher score, as K2 is more impactful for directing calcium to bones.
General Health 75.0
The combination of essential fat-soluble vitamins (A, D, K) provides a good foundation for various aspects of general health, including immune function and overall well-being.
Heart Health 70.0
The D3 and K combination provides some support, but without knowing if the Vitamin K is K2, its specific contribution to preventing arterial calcification for heart health is uncertain.
