Why buy from us?
We get it, you have a lot of companies to choose from.
We think you'd like our products because:
1. We open up our Certificates of Analysis for your reference BEFORE you make a purchase.
2. We pay for our own Certificates of Analysis testing and don't rely on any manufacturer's claims or certificates.
2. We do not sell anything containing irriatable excipients/fillers (ie: silica, titanium dioxide)
3. We are transparent about our process
4. We use glass, ceramic, and stainless steel as much as possible for bottling and storing.
Who is lark supply?
Hi there! lark supply is a microscopic family run business. We use our products daily, so we need to treat each bottle as if we we're going to use it :)
We do our best to provide quality products with details (certificates of analyses) we would like to know before ordering on a website that we would enjoy shopping at (privacy centered).
We think you should get to know us before ordering: please take the time to learn more about our process and visit our FAQ.

We are currently working on:
Updated Mar 11, 2026:
1. Vitamin A, Retinyl Palmitate: In our freezers, waiting on Vitamin E and MCT oil (not our favorite, but due to unsaturated nature of retinyl palmitate, it is easily oxidzied and requires a stable carrier oil. Vitamin E is added to also decrease oxidation).
2. Melted and sun exposed K2 purity testing: Working on the blog post...I'm slow sorry.
3. Water Lab Tests: Not a product, but wanted to share our results for our water quality tests including PFAS/PFOS for RO vs Distiller vs Filter & Softener vs Well Water (on the back burner for now, sorry)
4. Researching COAs to add to our testing list (ongoing)
5. Finding different suppliers (ongoing)
6. Organic Eggshells: We purchased a sample of organic eggshells and signing for a jet mill test run (6-8 weeks out from mid Mar 2026).
