Feb 19, 2025: We flubbed. The bottles and caps that we advertised as made in USA are actually, glass bottle: India, dropper cap: USA. We've since updated this page. See our blog post for further details.

Aug 5, 2025: We have noticed a rubbery smell coming from the dropper bulb that can permeate into the EVOOO. If you noticed this, please reach out to us for a free replacement bottle. Products shipped as of Aug. 4, 2025, have changed back to using the, previously out of stock, glass bottles after with a synthetic rubber (a thermoplastic elastomer called monprene) that should eliminate this issue. See post here.

Feb 17, 2025: It's best practice to shake the bottle before dispensing drops to ensure an even distribution of vitamin content with each drop. Remember to squeeze the dropper bulb while shaking.

We are currently shipping 1,000 IU/drop bottles with the following info (updated Feb 19, 2026):

Notes (updated Oct 1, 2025):

  • Please keep bottle in a cool & dark place and keep the lid tightly closed (don't over-hulk it though).
  • Ice pack & insulation option: each time you select this option, we will add 1 ice pack. We can fit 3 bottles with 2 ice packs per insulated pouch. If you only need 1 ice pack, please don't select this option on your other products.

Specifications (updated Feb 6, 2025, changes underlined):

  • Ingredients: Organic extra virgin olive oil (EVOOO) and vitamin D3 powder.
    • USP grade (we are told this meets USP's specifications, however we are unable to verify this claim).
    • you may see small particles of olives in solution, this is considered normal as part of the unfiltered milling process.
  • Excipients: None.
  • Vitamin D3 Source Material: Lanolin.
  • County of Origin:
    • Vitamin D3: See table above.
    • EVOOO: See table above.
  • 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?)
    • Bottle components country of origin: See tables above.
    • Bottle dimensions w/ dropper: 1.2 x 4 in (31 x 102 mm) (diameter x height).
    • Dropper lid & bulb materials: see specification tables above.
    • Total weight: 2.42 oz (68.62 g).
    • Notes on contents per bottle:
    • each VD3 1,000 IU/drop bottle contains:
      • 880,000 IU of Vitamin D3
      • EVOOO
        • 24.755 g of Terra Delyssa
        • or 26.183 g of Kasandrinos
    • each VD3 10,000 IU/drop bottle contains:
      • 8,720,000 IU of Vitamin D3
      • EVOOO
        • 25.215 g of Terra Delyssa
        • or 27.010 g of Kasandrinos
    • How did you come up with these ratios?
      • There's an extra "buffer" in each bottle to make sure we aren't short changing you:
        • 2.3% buffer in the ~1,000 IU/drop bottle
        • 1.5% buffer in the ~10,000 IU/drop bottle
        • Why 2.3% in the ~1,000 IU/drop bottle? Our scale's resolution is in milligrams, and it's quite difficult to weigh anything under 1 mg.
    • By our drop calculations, there are ~860 drops of solution in each bottle.
    • However, drop weights and drop counts varies depending on several factors. Please see the section in our FAQ regarding average drop weights that we currently use. Please also see our post regarding drop counts (for VK2 MK-4) for more details.
    • 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.

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.
  2. We use amber colored glass or wrap clear glass to block UV rays from reaching contents.
  3. We store bulk powder sealed in the freezer.
  4. We store EVOO at room temperature (74 - 78°F or 23.3 - 25.6°C) away from sunlight.
  5. We steam sterilize 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.
  7. Bulk powder we receive is usually stored in an aluminum or plastic container. We immediately weigh and move it to a glass container.
  8. More information about our process here.
  9. Please also review our Terms and Conditions before placing an order.

    Best brand I have ever tried

    Posted by mc on May 16th 2025

    This is hands down the best vD I have ever tried. I have tried practically every brand recommended by the RP community and every one has given me a skin condition and digestive issues (and I believe even a subtle tinnitus). I actually stopped taking supplemental vD last year because of this. For some reason I am extremely sensitive to something in vD generally. I barely notice any of these symptoms with Lark Supply even at high doses. To put a rough percentage on it, it has maybe 1/10 the allergenicity of the best other brand I tried (Premier). This effect is so small that I simply would have never noticed an allergenic connection if I started on Lark from the beginning. Please don’t ever change the way you manufacture it. You just found a life-long customer.

    High quality, trustable company

    Posted by Javier on Apr 14th 2025

    Lark Supply is the standard for good quality products for me now. The vast amount of information Richard provides makes me want to buy from his company for any supplement they release now and future.

    Best Vit D supplement money can buy

    Posted by Zachary Pavilonis on Apr 7th 2025

    Seed oil-free and lanolin-derived?? Sign me UP!! Fantastic value, too! I recommend this to all of my clients (who need it… which is most of them).

    Vitamin D3

    Posted by Marcus on Apr 5th 2025

    I had a favorite product before trying this but this is an even greater value and a top quality product. I'll be switching to Lark Supply now.

    D3 EVO

    Posted by Cb on Mar 27th 2025

    Best D3 supp I’ve used. Gentle rise in energy/clarity. Both my father and I agree it’s the best D3 we’ve used. No bad after taste. 5 drops a day as a supplemental dose. Excited to reorder after summer to supplement winter. Clear and transparent testing and processes. Will be ordering other products from Richard
