Analysis

The formula supplies 1,500 mcg of preformed vitamin A, 125 mcg of vitamin D3, and 1,000 mcg of vitamin K. These nutrients overlap in skeletal and calcium biology, but the K form is not identified.

A capsule intended for fat-soluble vitamins is convenient, yet the missing K subtype prevents assessment of MK-7 exposure or duration. Both vitamin A and D amounts require careful accounting of other dietary and supplemental sources.

It may fit a clinician-guided plan for specific fat-soluble vitamin needs. Most general users can find a more transparent and less aggressive formula.

Who is it for
  • Adults with documented fat-soluble vitamin needs
  • Users following a clinician-guided A-D-K plan
  • People who can monitor total vitamin A and D intake
Best for
  • Targeted high-strength fat-soluble vitamin support
  • Combining vitamins A, D, and K
  • Short-term use within a monitored plan

Pros

  • Combines three related fat-soluble vitamins
  • Uses cholecalciferol for vitamin D3
  • Clearly states total amounts
  • Provides a compact serving

Cons

  • Vitamin K form is not disclosed
  • Vitamin D3 exceeds the usual adult daily upper intake level
  • Uses a substantial amount of preformed vitamin A
  • Weak value given the transparency gap

Warnings

  • Vitamin K can counteract warfarin and other vitamin K antagonist anticoagulants; use requires prescriber-guided consistency.
  • The 125 mcg vitamin D3 amount exceeds the usual adult daily upper intake level and can contribute to excessive calcium when unnecessary.
  • Preformed vitamin A at 1,500 mcg warrants particular caution during pregnancy because retinol excess can harm fetal development.
  • Do not infer that the 1,000 mcg vitamin K amount is MK-7 because no K subtype is supplied.

Nutrient quality

71 High impact

Substantial fat-soluble vitamins provide a purposeful high-potency formula. Aggressive vitamin D3 and missing vitamin K form detail reduce balance and quality.

.

Ingredient transparency

73 High impact

All active amounts are stated and no proprietary blend hides the formula. Missing vitamin K form, intake directions, and excipient details reduce clarity.

.

Customer satisfaction

70 High impact

Aggregate satisfaction is very strong and supported by a substantial evidence base. No firsthand experience details are supplied, so recurring complaints and purpose alignment cannot be checked.

.

Value for money

69 High impact

Useful forms provide fair value despite some trade-offs. Better-priced or clearer alternatives may compare more favorably.

Vitamins A, D, and K form a coherent combination for calcium handling, skeletal support, and foundational nutrient coverage. The liquid capsule format also suits these fat-soluble vitamins, but the vitamin K form is not identified.

The vitamin D amount exceeds the usual adult upper intake level, and the high vitamin K amount can interfere with warfarin and related anticoagulants. Preformed vitamin A also warrants care during pregnancy, so the formula is better matched to a documented need than routine unsupervised use.

Vitamin D supports calcium absorption, while vitamin K may support calcium placement in bone. The vitamin K subtype is not identified, which limits confidence compared with a clear MK-7 formula.

High vitamin D and preformed vitamin A make the serving better suited to identified needs than casual long-term use. Vitamin K can oppose warfarin, and sustained high vitamin D can raise calcium too far in susceptible users.

Vitamin D and vitamin K form a logical calcium-management combination with cardiovascular relevance. The liquid capsule may support absorption of these fat-soluble nutrients.

The vitamin K form is not identified, so the amount cannot be judged as heart-focused MK-7. Vitamin K can counteract warfarin and other vitamin K antagonists, while the high vitamin D amount may be unsuitable when total intake or blood levels are already high.

High vitamin D and preformed vitamin A make the formula more suitable for identified needs than routine unsupervised use. Vitamin K can oppose warfarin and other vitamin K antagonists, so people using those medicines should not add it without prescriber guidance.

Vitamin D and vitamin K may work together in calcium management, which is relevant to vascular health. The vitamin K form is not identified, so a specific MK-7 arterial benefit cannot be assumed.

Both vitamin D and vitamin K are supplied at high amounts, while vitamin A adds little direct cardiovascular value. Vitamin K can oppose warfarin and similar anticoagulants, and the vitamin D amount reaches the usual adult daily upper limit.

Vitamin K · 1000 mcg OverallScore6
F Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

A large 1,000 mcg Vitamin K amount is paired with vitamins A and D, but the form is not disclosed. That omission prevents assessment of bioavailability, MK-7 dose, and anticoagulant relevance. The relatively high cost does not compensate for missing form transparency.
