Initial symptoms of scurvy include fatigue and soreness and stiffness of the joints and lower extremities.

Vitamin C is important in the formation of collagen (an element of normal tissues), and any deficiency of the vitamin interferes with normal tissue synthesis, a problem that underlies the clinical manifestations of the disorder.

While all the treatments were universally unpleasant, none did a thing to prevent scurvy. As the months wore on, the men’s vulnerability increased.
What did scurvy do to the explorers?
Scurvy affected many of the explorers we learned about in grade school: Vasco da Gama lost his brother to it; Ferdinand Magellan watched it kill many of his men, who had nothing to eat, he wrote, but “old biscuit reduced to powder, and full of grubs, and stinking from the dirt which the rats had made on it when eating the good biscuit.” The most famous scurvy-related disaster, however—and the one that fully captures the enduring importance of the tart substance we call vitamin C—was the ill-fated voyage of George Anson, whose 1740–1744 circumnavigation of the globe was the scene of one of the worst medical disasters at sea.
Why did the Anson expedition abandon the Gloucester?
But the disease resurfaced during their Pacific crossing in the summer of 1742, killing up to five sailors a day; in mid-August they were forced to abandon the Gloucester because there weren’t enough men to repair it.

Why do people get scurvy?
Scurvy, including subclinical scurvy, is caused by a deficiency of dietary vitamin C since humans are unable to metabol ically synthesize vitamin C . Provided the diet contains sufficient vitamin C, the lack of working L-gulonolactone oxidase (GULO) enzyme has no significance, and in modern Western societies, scurvy is rarely present in adults, although infants and elderly people are affected. Virtually all commercially available baby formulas contain added vitamin C, preventing infantile scurvy. Human breast milk contains sufficient vitamin C, if the mother has an adequate intake. Commercial milk is pasteurized, a heating process that destroys the natural vitamin C content of the milk.
Why are West Indian limes used in scurvy?
It was the acid, not the (then-unknown) Vitamin C that was believed to cure scurvy. In fact, the West Indian limes were significantly lower in Vitamin C than the previous lemons and further were not served fresh but rather as lime juice, which had been exposed to light and air, and piped through copper tubing, all of which significantly reduced the Vitamin C. Indeed, a 1918 animal experiment using representative samples of the Navy and Merchant Marine's lime juice showed that it had virtually no antiscorbutic power at all.

Why was Lind's study important?
The importance of the study is that Lind was right to control the variables of the experiment so that all subjects were in similar conditions, so that like was compared with like. According to his own account, the Scotsman chose patients with similar symptoms, kept them in the same place and provided them with a common diet, apart from the supplements, but without a control group.
Why did people die on long sea voyages?
Until a couple of centuries ago, everyone who embarked on a long sea voyage knew that he would be exposed to a fatal ailment that would rot the gums, cause open sores to appear on the skin and leave him prostrate, before leading to death. And there was no way around it since, according to the thinking of the time, it was due to the conditions of the crossings, such as the poor diet, dirty water, hard work and unhealthy housing.
Did Lind cure scurvy?
But beyond the idea that Lind’s clinical trial might not have been the first, some even doubt that any such trial ever actually took place. In 2003, a study revealed that the logbooks of the HMS Salisbury hardly recorded any cases of scurvy until the ship docked in Plymouth in June. Its author, Graham Sutton, suggested that the culture of the Royal Navy tended to deny the diseases on board: “If the Navy’s own records were taken at face value, Lind never cured scurvy on the Salisbury because there was no sickness there for him to treat,” wrote Sutton. Magiorkinis stresses that the British Navy tended to minimize disease, “since they considered deaths from scurvy to be a disgrace attributed to bad organization.”
When did the British make citrus compulsory?
Regarding the latter, and probably due to the half-heartedness of Lind’s conclusions in later editions of his work, 42 years had to pass from the publication of the work before the British admiralty would finally, in 1795, make citrus compulsory in the diet of sailors. Lind had died the previous year.
