Spirulin Plus Review: Good Greens, Bad Acid-Alkaline Science

Spirulin Plus is a greens blend, spirulina, chlorella, alfalfa, nettle and green tea, that is nutritious enough in principle. The problem is its central premise: deacidifying the body and restoring pH balance. That is not how human physiology works; your body tightly controls its own pH. With no doses disclosed and a debunked core claim, it is an ordinary greens supplement dressed up as something it is not.

Value & full review

What Spirulin Plus is

Spirulin Plus is a two capsule a day greens supplement, led by spirulina and chlorella, marketed to deacidify the body and restore its pH balance.

The premise does not hold

We have to correct the core idea. Your body keeps its blood pH within a very tight range automatically, using your lungs and kidneys. Foods and supplements do not meaningfully acidify or deacidify the body, and the notion that acidification causes broad ill health is not supported by science. So the central selling point here is not valid.

What is actually fine

Strip away the pH story and you have an ordinary greens and algae blend. Spirulina and chlorella are genuinely nutritious, so as a greens supplement it is harmless enough. The catch is that no doses are disclosed, and plain spirulina or a greens powder usually costs less and tells you exactly what is inside.

How to use it

Two capsules a day. Choose a reputable brand, since algae can be contaminated if poorly sourced.

Our verdict

A decent greens blend sold on a debunked pH premise with hidden doses. If you want spirulina, buy it directly. There is no reason to pay a premium for the acid alkaline story.
