Our lab results
Independent heavy metal and microbe tests for every lot we sell, with the full reports.
Our current lots have been tested twice. Our manufacturer tests every lot before it ships. Then Alkemist Labs, an independent lab in Garden Grove, California, tested a sample of each lot we sell now for heavy metals and microbes. Every result passed. The full reports are below, exactly as Alkemist issued them.

What these reports show, and what they do not
Each report covers the sample Alkemist tested from that lot. A lab result tells you what was in that sample. It is not a health claim, and we do not make one from it. Alkemist Labs tested our products at our request and does not endorse Holistico.
Our manufacturer's own certificates for each lot are available on request. Email hello@shopholistico.com.
Is Holistico third-party tested?
Yes. Alkemist Labs, an independent lab in Garden Grove, California, tested our current lots of Whole Food Vitamin D3 + K2 and Whole Food Calcium for heavy metals and microbes in September 2026. All four reports passed, and each one is on this page in full.
Who is Alkemist Labs?
An independent analytical lab in Garden Grove, California. They tested samples we sent them. They do not make or sell our products, and they do not endorse Holistico.
Which heavy metals were tested?
Arsenic, cadmium, mercury and lead, by ICP-MS under the USP <561> method. Every result on both products was under its limit. Mercury was below the lab's lowest reported level (under 0.010 µg/g) on both.
Which microbes were tested?
E. coli, Salmonella, aerobic bacteria, yeast and mold, and enterobacteria. E. coli and Salmonella were absent, and none of the other three were detected, on both products.
Does your manufacturer test as well?
Yes. Our supplements are made in an FDA-registered, cGMP-certified facility in Hauppauge, New York, where every batch is tested for potency, ingredient identity, microbial safety and heavy metals before it is released. Those certificates are available on request.
Where do I find the lot number on my bottle?
On the very bottom of the bottle, so you won't see it while the bottle is standing up. Match it to the lot numbers in the table above.
My bottle's lot number isn't listed. What now?
Email hello@shopholistico.com with the lot number from your bottle and we will send you the reports for it.
