What does 40:1 mean on this beet powder?

It means the powder is a concentrated extract: roughly 40 parts of raw beet went into 1 part of powder. A serving is therefore much smaller than with plain ground beet root.

How do I use it before a workout?

Mix a small scoop into water, juice or a smoothie about 30 to 60 minutes before training. Start with a small amount to judge taste and tolerance.

Does it taste like beets?

Yes. It is unflavored beet root, so it has an earthy, slightly sweet beet taste. Mixing it into juice or a smoothie masks it better than water alone.

Is it vegan and non-GMO?

Yes. The product is described as organic, vegan and non-GMO.

How does it compare with plain beet powder?

The 40:1 extract is more concentrated, so you use less per serving. Plain beet powder is bulkier and milder in concentration but usually cheaper per ounce.
