A vitamin is an organic compound and a vital nutrient that an organism requires in limited amounts.

An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet; thus, the term vitamin is conditional upon the circumstances and the particular organism.

For example, ascorbic acid (one form of vitamin C) is a vitamin for humans, but not for most other animal organisms.

Supplementation is important for the treatment of certain health problems, but there is little evidence of nutritional benefit when used by otherwise healthy people.

The human body is the entire structure of a human being.

It is composed of many different types of cells that together create tissues and subsequently organ systems.

They ensure homeostasis and the viability of the human body.

Skin is the soft outer tissue covering vertebrates.

Other animal coverings, such as the arthropod exoskeleton have different developmental origin, structure and chemical composition.

The adjective cutaneous means "of the skin" (from Latin cutis, skin).

In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue, and guards the underlying muscles, bones, ligaments and internal organs.

Skin of a different nature exists in amphibians, reptiles, and birds.

All mammals have some hair on their skin, even marine mammals like whales, dolphins, and porpoises which appear to be hairless.

Clinical trials are experiments or observations done in clinical research.

Such prospective biomedical or behavioral research studies on human participants are designed to answer specific questions about biomedical or behavioral interventions, including new treatments (such as novel vaccines, drugs, dietary choices, dietary supplements, and medical devices) and known interventions that warrant further study and comparison.

Clinical trials generate data on safety and efficacy.

They are conducted only after they have received health authority/ethics committee approval in the country where approval of the therapy is sought.

These authorities are responsible for vetting the risk/benefit ratio of the trial – their approval does not mean that the therapy is 'safe' or effective, only that the trial may be conducted.

Nature, in the broadest sense, is the natural, physical, or material world or universe.

"Nature" can refer to the phenomena of the physical world, and also to life in general.

The study of nature is a large part of science.

Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena.
