Specifications (updated Feb 15, 2025, changes underlined):

  • Ingredients: Extra Virgin Organic Olive Oil (EVOOO), Vitamin K2 MK-4 powder.
    • you may see small particles of olives in solution, this is considered normal as part of the unfiltered milling process.
  • Excipients: none.
  • Vitamin K2 MK-4 Source Material: Derived from geraniol, however because of the chemical reactions and transformations involved, this is considered a synthetic product (as opposed to an extract).
  • County of Origin:
    • Vitamin K2 MK-4: China (why China?)
    • EVOOO: Tunisia
  • Certificate of Analysis (COA) available online with every order (why the COA? | view COAs)
  • Bottled in an amber glass jar for protection from UV light (why amber?)
    • All bottle components are made in the USA
    • Bottle dimensions: 1.2 x 3.1 in (31 x 79 mm) (diameter x height)
    • Dropper lid & bulb materials: plastic, monprene rubber and glass
    • Total weight: 2.4 oz (68.2 g)
  • Notes on contents per bottle:
    • 1,756 mg of Vitamin K2 MK-4
    • 23.156 g of EVOOO
    • @ 1.756 g, there's an extra ~0.03 mg/drop or 1.5% buffer that we add to make sure we aren't short changing you.
    • By our calculations, there are ~860 drops of solution in each bottle @ ~2.03 mg of VK2 MK-4 per drop.
    • However, drop weights and drop counts varies depending on several factors. We use our standard average drop weight of 0.0288 grams. Please see our post regarding drop counts.
    • You may only be able to dispense ~850 drops using the dropper, with the remaining left as a film on the glass bottle and dropper (~10 drops). Use a mini scoop to scrape out the rest, or add a bit more EVOO and shake.
    • Technically, the weight/weight ratio of VK2 to solution is 1 to 14.187 (1.756 to 24.912). Meaning, if you want X mg of VK2, you would need 14.187 times X in weight of solution.

Disclosures (updated Dec 20, 2024, updates underlined):

  1. We use glass containers for storage and packaging, although caps and seals are usually made from silicone, plastic, rubber, or LDPE.

  5. We steam sterlize all glass bottles, containers, caps, liners, and utensils before using them for storage or bottling using distilled water.
  6. We prioritize the material of packing utensils all containers and utensils that come into contact with product in this order: glass, ceramic, stainless steel, plastic, aluminum.

    The Best

    Posted by Andrew J on Mar 10th 2025

    Richard’s commitment to quality and transparency is second to none. While most supplement companies include excipients, give you minimal information about what’s in the package, and are not concerned with the quality of their product, Lark Supply clearly takes all of these concerns to heart. The result is a truly astounding product that I have personally recommended to my friends and family.

    Products are Great. Richard is Great.

    Posted by Danny Roddy on Feb 16th 2025

    I can't say enough good things about Richard (owner of Lark), and I'm ecstatic that he started making two of the products that I use the most (vitamin K and D). Thanks for the lengthy R&D, Richard. Cheers.

    Most Affordable High Purity Vitamin K2

    Posted by Josh S on Jan 28th 2025

    I have used numerous other vitamin k2 products, and this one delivers. I noticed the same effects as other high purity K2s and was able to use in conjunction with calcium carbonate for increasing bone density. I also calculated out the price and Lark Supply outperforms other brands on price per milligram as well. Looking forward to continued development of their product.
