There is both natural (from algae) and synthetic astaxanthin. Supplements often use the natural algae form, because it comes directly from Haematococcus pluvialis. Doses of a few milligrams per softgel are common, for example 6 mg.

• Natural — from the microalga Haematococcus pluvialis.
• Synthetic — produced chemically; less common in premium supplements.
• Dose — often a few milligrams per softgel.

At Plenthera you will find astaxanthin under the name Astamax; see the details in our astaxanthin collection.

With astaxanthin, the source and the dose determine the quality. A natural source from Haematococcus pluvialis and a transparent manufacturer are preferable.

• Source — natural astaxanthin from microalgae.
• Dose — the amount per softgel.
• Softgel shell — check this if you want to remain vegan.
• Quality control — a transparent origin.
