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.
The safe upper limit for vitamin D is 1,000 to 1,500 international units (IU) per day for infants. For children aged one to eight years, the safe upper limit is 2,500 to 3,000 IU/day, and 4,000 IU/day for children nine years and older, adults and pregnant and lactating teens and women.
