THORNE Vitamin K (formerly 3-K Complete) - Vitamins K1 and K2 (as MK-4 and MK-7) - Supports Strong Bones - 60 Capsules

Q: Why is there so much silicone dioxide in each capsule? I would not expect this from Thorne.

The amount of silicon dioxide in Thorne’s 3-K Complete is less than 2 percent of the total formula and does not affect the quality, efficacy, or safety of the finished product. Silicon dioxide is used to minimize moisture content and to help powders flow into capsules. Although silicon is sometimes confused with silicone (which is a synthetic compound), there is no chemical similarity between these two substances. Silicon dioxide is a naturally-occurring compound that contains silicon, a mineral that is ubiquitous in nature and found in many foods, especially those high in fiber, and, because it is necessary for bone growth and maturation, it is also often added to nutritional supplements designed for bone support.

Q: How much Vitamin E is in this?

Thorne’s 3-K Complete contains 350 mcg of vitamin E, as mixed tocopherols, per capsule.

Q: what is the source of the K-2?

The vitamin K (K1 and K2) in Thorne's 3-K Complete is from natural source geraniol, a monoterpenoid and an alcohol derived from rose oil, palmarosa oil, and citronella oil.

Q: What is the vitamin a from? is it a natural source or synthetic? i see it is not soy. sunflower oil?

Thorne’s Vitamin K (formerly 3-K Complete) contains vitamin K1 and K2 (MK-4 and MK-7). The vitamin K1 and K2 (MK-7) are synthetic, vitamin K2 (MK-4) is derived from geraniol.
