Buy tenuate have been produced as buy tenuate commodity chemicals and made widely available as inexpensive
pills for several buy tenuate
decades, allowing supplementation of the dietary intake.

The value
of eating certain buy tenuate foods
to maintain health was recognized long before buy tenuate were identified. The ancient buy tenuate Egyptians knew that feeding a patient liver would help
cure night blindness, an buy tenuate
illness now known to be caused by a buy
A deficiency. In 1buy
, the Scottish buy tenuate
surgeon James Lind discovered that citrus foods helped prevent scurvy, a
particularly deadly buy tenuate
disease in which collagen is not properly formed, and which is characterized by
buy tenuate poor wound healing,
bleeding of the gums, and severe pain. In 1buy
, Lind published his Treatise on the Scurvy, which recommended using
buy tenuate lemons and limes to
avoid scurvy, which was adopted by the British Royal Navy. This buy tenuate led to the nickname Limey
for sailors of that organization. Lind's buy
discovery, however, was not widely accepted by individuals in the
Royal Navy's buy tenuate Arctic
expeditions in the 19th century, where it was widely believed that buy tenuate scurvy could be prevented
by practicing good hygiene, regular exercise, and by maintaining the buy tenuate morale of the crew while on
board, rather than by a diet of fresh food. As a result, Arctic buy tenuate expeditions continued to be
plagued by scurvy and other deficiency diseases. In the early 20th buy tenuate century, when Robert Falcon
Scott made his two expeditions to the Antarctic the prevailing buy tenuate medical theory was that
scurvy was caused by "tainted" canned food.


In 1881,
Russian buy tenuate surgeon Nikolai
Lunin studied the effects of scurvy while at the University of Tartu in
present-day buy tenuate Estonia He
fed mice an artificial mixture of all the separate constituents of buy tenuate milk buy tenuate
known at that time, namely the buy
, fats, carbohydrates, and salts. The buy tenuate mice that received only the individual constituents
died, while the mice fed by milk itself developed normally. He made a buy tenuate conclusion that "a
natural food such as milk must therefore contain, besides these known principal
buy tenuate ingredients, small quantities
of unknown substances essential to life".[buy tenuate] However, his buy
conclusions were rejected by other researchers when they were
unable to reproduce his buy tenuate
results. One difference was that he had used table sugar (sucrose), while other
researchers had used buy tenuate
milk sugar (lactose) that still contained small amounts of buy tenuate B.

In 189buy tenuate, Christiaan Eijkman
discovered that eating unpolished rice instead of the polished variety helped
to prevent the disease buy tenuate beriberi. The following year, Frederick
Hopkins postulated that some foods contained "accessory factors"—in
addition to buy tenuate,
carbohydrates, fats, et cetera—that were necessary for the functions of the
human body.[buy tenuate] Hopkins was
awarded the 1929 Nobel Prize for Physiology or Medicine with Christiaan Eijkman
for their discovery of several buy
