RE: Reasonable price for electric water heater installation? I am having an old 40-gallon electric water heater replaced with a new 40-gallon one. I was given a quote of about $1,200 for everything (price of new heater, cost to take away the old one, and cost to install the new one).
Even without B-vitamin deficiencies, taking high doses of methionine â 7 grams daily or more â can increase your homocysteine levels. Taking up to 2 grams per day of methionine doesnât appear to cause any serious adverse effects, however. Creatine supplements pose their own risks as well, particularly the risk of kidney damage, when taking high doses, and heart arrhythmias.
But too much be dangerous. Very high doses of vitamin D can raise your blood calcium level, causing damage to blood vessels, heart, and kidneys. The Institute of Medicine sets the upper tolerable limit at 4,000 IU of vitamin D per day. You canât get too much vitamin D from the sun.
