Science of 5-ALA

No. However, heme which is produced from 5-ALA is the “active center” of various enzymes. Please see “about 5-ALA” for further details.

Proteins in the human body are composed of 20 alpha-type amino acids, but 5-ALA is classified as a delta-type amino acid that is not used to build proteins.
Ornithine, a well-known supplement, is also a delta-type amino acid, but it has a completely different function.

Human cells cannot produce vitamin B12, and intestinal bacteria are known to produce it from 5-ALA.

We have not examined whether orally administered 5-ALA is converted into vitamin B12.


The SBI Group’s main business is finance, but is affiliated with the bio sector. SBI Pharmaceuticals is one of its companies.

Results are disclosed in the IR information of SBI Holdings, Inc. (listed on the Tokyo Stock Exchange First Section: 8473).
