Silicon from Bamboo Extract, 300mg

Description

Silicon from bamboo extract 300mg, standardised to 70 percent silica, 90 servings at about 23 cents each. The plant is Bambusa vulgaris and the part used is the stem, which is the densest plant source of silica anyone has found. A bamboo extract 300mg capsule therefore carries about 210 mg of silica, and that figure is the start of the arithmetic rather than the end of it.

Label figures

Silica is not silicon, and a bamboo extract 300mg label should say both

Silica is silicon dioxide. Silicon makes up 46.7 percent of it by mass and oxygen accounts for the rest, so 210 mg of silica contains roughly 98 mg of elemental silicon. Most bottles print the silica figure, a few print the extract weight only, and almost none print the element.

All three numbers are on this listing because they differ by a factor of three and a buyer comparing two products across two different conventions will reach the wrong answer. The same elemental against compound arithmetic runs through every item on the minerals page.

What the research measured, and which form it used

Here is the part that does not flatter this category. Most human silicon research used orthosilicic acid, usually choline stabilised, at 5 to 20 mg of silicon a day, measuring bone turnover markers, bone mineral density and hair and nail assessments. Silica from a plant is a polymerised solid and has to depolymerise to be absorbed at all.

So the studied form and the shelf form are not the same material, and the comparative absorption data on bamboo extract 300mg capsules specifically is thin. That is a description of the literature rather than a claim about this bottle, and we would rather print it than let the milligram figure imply more than it supports.

Why a bamboo extract 300mg capsule counts as a vegan product

The silica alternatives are worth laying out. Horsetail is a plant. Mineral silicon dioxide preparations are not plants at all, and some are sold as anti-caking agents rather than as nutrients. Collagen and gelatin carry silicon as a minor component and are animal derived, so they are out for anyone avoiding animal material. A bamboo extract 300mg capsule uses a plant stem inside a plant based shell, and the certificate names the capsule material instead of leaving a buyer to assume it.

Bamboo against horsetail

Horsetail, Equisetum arvense, is the traditional silica herb and it carries thiaminase, an enzyme that degrades thiamine, which is why long term use of the raw herb has a caution attached. Bamboo stem has a higher silica content and no thiaminase, and it is the reason this bottle exists.

Dietary silicon, for scale

Silicon has no recommended intake in the United States, and estimates of ordinary dietary intake run between 20 and 50 mg a day, mostly from grains, beer and drinking water. A capsule here sits well above that. The absence of an official reference figure is itself worth knowing before paying for a supplement of it.

Testing

Every lot is identity tested, assayed for silica content and screened for lead, cadmium, arsenic, mercury, pesticides and microbials by a laboratory with no ownership tie to this company. Under strength lots are pulled and the failing report stays published. Botanical identity matters here too, since milled stem powder gives no visual clue which grass it came from.

Where it sits

This bamboo extract 300mg listing sits with the collagen, glucosamine and strontium items on the joint and bone page. For free reference material on minerals and the state of their evidence, the NIH Office of Dietary Supplements fact sheet library is the place to start, and your lot certificate is linked on this page.
