Pea Protein Isolate, Unflavored, 2.2lb

Description

Pea protein isolate from yellow peas at 80 percent protein by weight, unflavoured, 2.2 pounds in the bag and 33 servings at about a dollar each. Eighty percent is the figure to hold onto: a 30 gram scoop of this pea protein isolate delivers around 24 grams of protein, and the remaining 6 grams is the starch, fibre and minerals that survive the isolation process.

The numbers on the bag

Why pea protein isolate is nearly always paired with rice

Pea protein runs low in methionine and cysteine, the sulphur amino acids, and comparatively high in lysine. Rice protein has the opposite shortfall. Blending the two covers both gaps, which is why almost every plant protein on the market is a pea and rice mixture rather than either one alone.

Buying the isolates separately lets you set the ratio yourself and costs less per gram than a flavoured blend. Both are stocked, and the methionine and lysine figures for each are published on the protein page rather than summarised as a complete profile.

Isolate against concentrate, in plain numbers

A pea protein concentrate runs nearer 70 percent protein and costs less per bag. A pea protein isolate is filtered further, reaching 80 percent or more, with less of the starch and fibre that give concentrates their flavour and their texture. Both are honest products. The percentage is what decides value, and it is printed on every listing beside the scoop weight.

Heavy metals, the real question with plant proteins

Plants concentrate what is in their soil, and protein isolation concentrates it again. That is why every lot of this pea protein isolate is screened for lead, cadmium, arsenic and mercury by an outside laboratory and the panel is published with the listing. Peas are generally lower risk than rice in this respect, which is a reason to read both certificates when buying a blend.

What the research measured

Comparison trials have fed matched protein doses, usually 20 to 48 grams, and measured muscle thickness, strength and body composition over eight to twelve weeks of resistance training, with some protocols sampling blood amino acid concentrations. Differences between pea and whey at matched doses were generally small. That describes the published findings and the amounts administered, and it is not a claim about this bag.

What a pea protein isolate costs per gram of protein

A dollar a serving for about 24 grams of protein is near 4.3 cents per gram, and that figure is the only honest way to set a pea protein isolate beside whey, casein or a flavoured blend. Bag price hides scoop weight. Scoop weight hides the protein percentage. Price per gram of protein hides nothing at all, which is why it sits under the price on every listing here and why the method is set out in why price per milligram beats the price on the bottle. An unflavoured pea protein isolate wins that comparison more often than buyers expect.

Taste and mixing, said plainly

Unflavoured pea protein tastes of peas and is slightly chalky in water. It disappears in a smoothie with fruit or cocoa and it does not disappear in plain water, whatever a product page tells you. Buying unflavoured means the whole scoop weight is protein and filler rather than sweetener, and it means you decide the flavour.

Testing

Every lot goes to a laboratory outside this business for protein content measured by a method that is not nitrogen alone, a full amino acid breakdown, heavy metals and microbials. Lots assaying under their stated grams are withdrawn and the certificate stays published.
