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. For fragile X syndrome, 10-250 milligrams of folic acid has been taken by mouth daily for 2-8 months with a lack of effect on symptoms.
Capsules of folinic acid and placebo will be administered in 1mg/kg/day in two divided doses (0.5mg/kg/dose; 25mg/day maximum) for two weeks followed by 2 mg/kg/day with a maximum dose of 50mg/day provided the lower dose is well tolerated for 10 weeks.
