Explanation of the term "L-ascorbic acid" should begin with discussing what vitamin C is. Under the common name of vitamin C, there are two compounds - L-ascorbic acid and L-dehydroascorbic acid. Ascorbic acid C5H8O6 is a y-lactone of 2,3-endiol-L-gulonic acid with strong reducing properties, and dehydroascorbic acid is its oxidized form. Most animals are capable of synthesizing vitamin C in their liver, but humans, monkeys, guinea pigs, and some fish are among those that cannot.
Recently, a trend has emerged for so-called "L-ascorbic acid," which is supposed to be a natural alternative to the synthetic vitamin offered in pharmacies - a versatile supplement that guarantees almost miraculous health benefits.
The molecule of vitamin C has an L configuration, which does not mean that it is left-handed. Optical rotation is another property of the molecule, based on the way it rotates polarized light - to the right or to the left. It is indicated not by letters, but by symbols "+ " and "-", respectively for right and left-handedness. L-ascorbic acid has a "+ " sign and is right-handed. In other words, the vitamin C molecule rotates the plane of polarization of light to the right, so it is right-handed.
The molecule of D-ascorbic acid is left-handed, but it is not vitamin C or any other compound because it has no biological activity.
To summarize: there is no such thing as left-handed or right-handed vitamin C, and the confusion around vitamin C relates to the confusion between optical rotation, indicated by the symbols "+ " and "-", and spatial isomerism (symbol L- or D-).
From a chemical point of view, everything is clear, and the myth of left-handed vitamin C was invented due to ignorance and marketing needs. The concept of left-handed vitamin C is internally inconsistent.
When deciding to supplement, it is important to choose a product based on scientific research, not marketing experiments!
By choosing Cheers, you choose uncompromising quality.
A perfect alternative to synthetic vitamin C is natural vitamin C, which, like its synthetic counterpart, takes the form of L-ascorbic acid, also known as left-handed vitamin C. However, it is much better absorbed by the body. There are two reasons why natural vitamin C has an advantage over synthetic vitamin C - natural vitamin C is identical to that found in the diet, and is therefore well tolerated by the body.
Secondly, natural vitamin C supplements are sourced from fruit extracts, especially acerola and wild rose, which provide large amounts of bioflavonoids. These significantly increase the bioavailability of ascorbic acid. Therefore, if you want to supplement this vitamin, choose natural vitamin C 1000 mg.
The price of vitamin C - what does it depend on?
When going to a pharmacy or making a purchase in an online store, many of us are guided primarily by the price of the product, often choosing the cheapest option. Is this the right approach? It turns out it is not. Just as it is incorrect to say that vitamin C is simply one compound that is present in identical form in every supplement, the truth is slightly different. Synthetic vitamin C, obtained in the laboratory through chemical reactions, does not differ in any way regardless of the type of supplement. However, the same cannot be said for natural vitamin C - firstly, it is a compound of incomparably higher quality than synthetic vitamin C. Secondly, depending on the source of extraction, natural vitamin C may be accompanied by many valuable active substances that increase the effectiveness of the supplement.
