Spirulina Micro-Algae 760 mg

The 2,000 mg organic spirulina serving is substantially larger than the original and still lists 1 g protein. Vitamin A and iron are also disclosed, making it the closest higher-dose algae alternative in the supplied list.

A 20 g whey protein isolate serving provides far more protein than the original algae capsules. It does not contain spirulina, so it is a better fit only when protein intake matters more than blue-green algae.

The whey formula supplies 24 g protein with modest carbohydrate and fat amounts clearly listed. It greatly improves protein coverage over the original, but provides none of spirulina's algae-specific ingredients.

The much lower cost per serving keeps spirulina central and adds identified vitamin A and vitamin K contributions. Its listed spirulina amount is lower than the original, so the value gain comes with a smaller serving.

A lower cost per serving provides 950 mg certified organic spirulina plus astaxanthin. It supplies slightly more spirulina than the original, although no protein amount is listed in the supplied data.

Klamath Lake blue-green algae is a close category match at nearly the same cost per serving. The 500 mg serving is smaller than the original spirulina amount, and the input does not list protein or vitamin content.

The unflavored casein supplies 19 g protein with a relatively low serving cost for a protein product. It offers much stronger protein value than the original, though it is not an algae substitute.

Pea protein provides 13 g protein from 18 g concentrate at a moderate cost per serving. It is a practical plant-protein value option, but lacks spirulina and the original product's beta-carotene contribution.

Rice protein supplies 12 g protein at a moderate cost per serving and keeps the formula simple. It improves protein value substantially, while giving up the original spirulina and vitamin A content.
