Chlorella Broken Cell Wall

Description

Chlorella with the cell wall mechanically cracked rather than left intact. This single processing step is the whole specification. Chlorella is a freshwater green alga whose cell wall is largely cellulose, which human digestion does not break down, so whole cell chlorella passes through substantially unopened. Cracking the wall by bead milling or pressure is what makes the contents available, and it is the reason this costs more than the undisrupted powder.

What is in the tub

Why broken cell wall chlorella is worth the difference

A nutrient inside an indigestible cellulose box is not a nutrient you can use, and that is the plain version of the argument. The disruption step is mechanical here rather than chemical, which means no solvent residue to screen for and no enzyme preparation in the ingredient list. Labels that say chlorella without saying broken, cracked or disrupted are usually selling the cheaper material.

What the step does not do is change the composition. The protein, chlorophyll, vitamin and mineral figures on the certificate are the same before and after cracking. Only availability changes, and nobody can put a number on that from a label, which is why we describe the process instead of claiming a percentage.

Heavy metals, the real question in this aisle

Algae take up what is dissolved in the water they grow in, and they concentrate it. That is a straightforward biological fact and it is the reason every lot of chlorella here goes to an independent laboratory for lead, cadmium, arsenic and mercury before it is listed, with the results published rather than summarised as tested.

Growth conditions matter more than species. Open pond cultivation in an industrial catchment is a different proposition from a closed system, and the certificate is the only place that difference becomes visible to a buyer. Our reasoning on publishing every result, including the bad ones, is in why we publish the batch that failed.

Spirulina, which is a different organism

The two get shelved together and they are not close relatives. Spirulina is a cyanobacterium with no cellulose cell wall, so there is nothing to crack and no broken wall version of it. The green alga here is a eukaryote with a tough wall, which is the entire reason a processing step appears on this label and none appears on that one.

Composition differs too. One runs higher in protein by weight, the other higher in chlorophyll and nucleic acids, and both are sold by the gram. Anyone buying on protein content should read the assay rather than the colour of the tub, and both sit side by side on the greens and wholefood page with their figures printed.

Tablets or powder

Chlorella tablets are easier to take and cost more per gram, since pressing adds a step and a binder. Powder is cheaper and tastes of what it is. Published studies have used both formats without distinguishing between them, so the choice is about whether you will keep taking it rather than about the material.

What the published work covers

Human studies on this alga are mostly small, use varying preparations and doses between 3 and 10 grams a day, and measure blood lipid panels, immune markers and nutrient status indicators. There is no established intake and no single standardised preparation across the literature, which makes cross study comparison difficult. That is a description of the evidence rather than a claim about this tub.

Using it

It tastes green in the strongest sense of the word and it stains. Most people take it in a smoothie or in tablets rather than stirred into water. The rest of the algae and leaf powders sit on the greens and wholefood page, where per ingredient amounts are listed individually, and intake references for the individual nutrients are on the NIH fact sheet library. The lot report sits above, next to the price.
