The flour meets FDA regulations, TerraVia adds. It has been used in "more than 20 million servings" without proof of adverse effects.

Soylent isn't exactly ruffled by the move. It tells us that the cutoff will have "no impact," since Powder is already algal flour-free and will eventually be joined by a reformulated Bar.

The company didn't address TerraVia's specific allegations in its statement (available below), but it might not have to -- as far as it's concerned, business continues as usual.
