In some areas, like the west of Ireland and Scotland, kelps and other brown algae are gathered as a fertiliser for land. There are about 1800 species of brown algae, and most are marine. In general, brown algae are larger and more species are found in colder waters.Virtually all the biomass worldwide comes from a relatively small number of species in the orders Laminariales and Fucales.haracteristics. The brown colour of these algae results from the dominance of the xanthophyll pigment fucoxanthin, which masks the other pigments, Chlorophyll a and c (there is no Chlorophyll b), beta-carotene and other xanthophylls.
In addition, for severe folate deficiency, 1-5 milligrams has been taken by mouth daily until blood levels are corrected and documented by a qualified healthcare professional.

Oral dosage (magnesium chloride, magnesium gluconate, magnesium lactate, magnesium oxide, or magnesium sulfate): Children: 10â20 mg elemental magnesium/kg/dose PO four times per day. Parenteral dosage (magnesium sulfate): Adults: 1â2 g IV/IM (or 15â30 mg/kg lean body weight) every 6 hours for 24 hours. Use the higher end of the dosage range for serum Mg concentrations < 1.2 mg/dl. For extreme hypomagnesemia, 8â12 g/day IV in divided doses have been used.
