Brown Rice Protein Isolate, 2.2lb

Description

Brown rice protein isolate from sprouted rice, 2.2 pounds in the bag, 33 servings at about 1.09 dollars each. A kilogram divided 33 ways is close to a 30 gram scoop. Brown rice protein isolate is the standard partner to pea protein, and the reason is the amino acid chart: rice runs low in lysine and reasonably high in methionine, pea does the reverse, and the pair covers both gaps.

The numbers on the bag

The arsenic question, which belongs on this page

Rice takes up arsenic from paddy soil and water more readily than other cereal crops. That is agricultural chemistry rather than a scare, and it means a rice derived protein concentrates whatever the grain held. Independent consumer testing has repeatedly found measurable heavy metals in rice protein powders, and a brown rice protein isolate without a published metals panel is a product asking you to assume.

Every lot here goes to an outside laboratory for inorganic arsenic, cadmium and lead before it is listed, and the figures are published rather than summarised as tested. Our reasoning on publishing the failures as well as the passes is in why we publish the batch that failed.

Pairing a brown rice protein isolate with pea

The usual ratio in commercial blends is roughly 70 parts pea to 30 parts rice, which lifts lysine without losing the methionine the rice supplies. Buying the two separately and mixing them is cheaper per gram of protein than a finished blend, and the amounts stay yours to set rather than arriving as one combined figure. The pea isolate and the ready made blends sit beside this brown rice protein isolate on the protein page.

Why a brown rice protein isolate scoop is large

Plant isolates arrive at a lower protein percentage than whey isolate, which runs above 90 percent, so a 30 gram scoop is what it takes to reach a useful figure. That is a composition fact rather than a failing. It is also why price per gram of protein is the only honest comparison between a brown rice protein isolate and a dairy powder, and both numbers are printed under the price.

Isolate, concentrate and what sprouting does

An isolate is filtered further than a concentrate and arrives at a higher protein percentage with less starch carried along. Sprouting the grain before processing is a separate step, used to improve the texture and reduce the chalkiness rice protein is known for. Neither step changes the amino acid profile in any meaningful way, and both are stated rather than implied.

Scoop weight against grams of protein is the figure to read, as the protein page sets out. A 30 gram scoop yielding 24 grams is 80 percent by mass, and the percentage is printed so a cheap bag cannot hide a thin scoop.

What the comparison trials measured

A controlled training study fed matched doses of rice protein isolate and whey, around 48 grams a day, for eight weeks, and measured body composition, strength and recovery markers, reporting similar outcomes between the two groups at that dose. Other work has measured amino acid appearance in blood after rice protein feeding.

Those are the doses administered and the endpoints recorded in the literature, and the dose in that trial was substantially more than one scoop. It is not a claim about this bag.

Taste, honestly

A brown rice protein isolate is chalkier than whey and slightly gritty however well it is processed, and unflavoured rice protein tastes of rice. Blending it with pea improves the texture as well as the amino profile, which is why most plant blends on the market are built that way.

Testing

Protein content by a method that is not nitrogen alone, a full amino acid breakdown, heavy metals and microbials, on every lot, by a laboratory outside this business.
