In coastal marine ecosystems, neurotoxins produced by harmful algal blooms (HABs) often result in large-scale mortality events of many marine species. Historical and frequent exposure to HABs therefore may provide a strong selective pressure for adaptations that result in toxin

Betaine supplementation in humans has been shown to lower plasma homocysteine concentrations in modestly hyperhomocysteinemic patients. Betaine treatment is associated with increased plasma low-density-lipoprotein (LDL) cholesterol, suggesting that although betaine supplementation lowers homocysteine, a risk factor for cardiovascular disease, changes
