In addition to natural magnesium oxide from the Dead Sea, our magnesium capsules also contain 38% sea lettuce extract (Ulva lactuca).
The algae “Ulva lactuca” is generally very rich in various macro- and micronutrients and also contains the trace element selenium. However, the content may fluctuate as it is a natural product. We do not have our magnesium capsules analyzed for standardized selenium content, but Ulva lactuca typically contains around 0.1 to 1.0 mg selenium per kilogram (dry weight).
We recommend a dosage of 1 capsule per day, which contains approx. 330 mg Ulva lactuca. Accordingly, the amount of selenium is in the very low microgram range.
