I know this has been discussed before, but couldnt really put one and one together.

I am looking into buyin my biotin from Freeda, but when I went to check out the pricing, it said d-biotin, and I recall someone saying that the d meant it was synthetic, and not all natural.

Someone please enlighten me?

Biotin is found in its simplest chemical form, D-biotin, in virtually all dietary supplements. This form of the vitamin is the only known metabolically active form.

Chemically, natural and synthetic vitamins are identical. The same ingredients are contained within the molecules but they are arranged in a different fashion. When a beam of polarized light passes through a natural vitamin it will always bend to the right, due to the molecular rotation of the natural substance. The letter "d" seen on some supplement labels represents dextro or "right." This indicates that the vitamin is the natural form.

As a beam of polarized light passes through a synthetic vitamin it splits into two parts, one part bending to the right and the other to the left. The synthetic supplements may be represented by the letters "dl" preceding the vitamin name. The "d" for dextro and the "l" for levo or left. This demonstrates that the molecular rotation of the synthetic is not identical to the natural form. The biological activity of synthetic vitamins can be 50% to 70% less than nutrients in natural, whole food supplements.

B vitamins are not generally referred to in conjunction with these letters but the difference in molecular structure between synthetic and a truly natural substance applies to them as well as any other nutrient.

Whole food supplements and some "natural" supplements will give foods as sources for the nutrients they contain. If a supplement is synthetic it will usually show the following as sources:

B complex – no source listed

B1 – thiamine mononitrate or thiamine hydrochloride

B2 – riboflavin

B5 – calcium D-pantothenate

B6 – pyridoxine hydrochloride

B12 – cobalamin

Folic Acid – pteroylglutamic acid

Biotin – d-Biotin
