Frequently Asked Questions
What does GMP A-rated certification actually mean for this supplement?
GMP (Good Manufacturing Practice) is the standard the FDA uses for dietary supplement production, and an A-rating is the highest level awarded. It means NOW's facility has passed an independent audit for ingredient handling, equipment, personnel training, and quality control procedures.
How do I know the potency on the label matches what's actually in the capsule?
Every batch is tested in-house at an ISO/IEC accredited lab for stability, potency, and formulation accuracy. This third-party verifiable testing confirms that the 1,000 IU of D3 and 45 mcg of K2 listed on the label are present through the expiration date.
Is this formula safe to take long term without cycling off?
For most healthy adults, the 1,000 IU D3 and 45 mcg K2 (MK-7) dose is well studied for daily long term use. As with any supplement, we recommend discussing ongoing use with your healthcare provider, especially if you take blood thinners or have a medical condition.
Does the vegetable capsule contain any animal derived ingredients?
No. The capsules are made from plant-based materials and are completely free of gelatin, which is normally derived from bovine or porcine sources. This makes them suitable for vegetarians, vegans, and anyone avoiding animal-derived ingredients.
Are there any major allergens I should worry about?
The formula is Non-GMO, Kosher certified, and Soy Free, which addresses three of the most common dietary concerns. The label clearly states all certifications so shoppers with restrictions can verify at a glance.
How should I take this D3 K2 supplement for best results?
Take one vegetable capsule daily with a meal that contains some fat, since Vitamin D3 is fat soluble and absorbs more efficiently with dietary fat. Consistency matters more than timing, so choose a meal you eat every day and stick with it.
Can I take this alongside my other supplements like calcium or magnesium?
Yes, this formula is designed to stack well with calcium and magnesium. D3 helps your body absorb the calcium, and K2 directs it to your bones. Magnesium supports the activation of Vitamin D, so the combination is complementary.
Do I need to refrigerate the bottle after opening?
No refrigeration is required. Store the bottle in a cool, dry place away from direct sunlight and moisture, and keep the lid tightly closed between uses to preserve potency through the expiration date.
Is this supplement compatible with a vegetarian or vegan diet?
Yes. The capsules are made from plant-based materials, and the formula is Non-GMO, Kosher, and Soy Free. While the Vitamin D3 source is derived from lanolin (sheep's wool), many vegetarians who are not strict vegans accept this form, and the vegetable capsule itself contains no animal-derived gelatin.
Will this interfere with any medications I am taking?
Vitamin K2 can interact with blood-thinning medications such as warfarin. If you take anticoagulants or any prescription medication, consult your healthcare provider before starting this or any D3 K2 supplement.
What comes in the box when I order this product?
You will receive one sealed bottle of NOW Supplements Vitamin D3 and K2 containing your selected capsule count (120, 180, 240, or a multi-pack configuration). A safety-sealed inner liner protects freshness. Nothing else is required for use, and the bottle is ready to place in your supplement station immediately.
Are there any side effects I should watch for?
Most users tolerate this formula well at the recommended dose. In rare cases, high-dose Vitamin D can cause mild digestive upset, and Vitamin K2 may interact with blood thinners. Start with one capsule daily and speak with your doctor if you have a medical condition or take prescription medication.
Is NOW Supplements a trustworthy brand compared to private label competitors?
NOW has been family owned and operated since 1968, giving them over 50 years of formulation and manufacturing experience. They hold an A-rated GMP certification, run ISO/IEC accredited in-house labs, and produce in their own facility rather than outsourcing, which gives them tighter quality control than most private label brands.
What is the difference between Vitamin K2 MK-7 and other forms like MK-4?
MK-7 (menaquinone-7) has a longer half-life in the body than MK-4, meaning it stays active longer and requires a smaller daily dose. MK-4 typically needs multiple doses per day and higher milligram amounts, while MK-7 delivers steady coverage with just 45 mcg once daily, which is why it is the preferred form in this formula.
