Arachidic acid, also known as eicosanoic, is a component of wild soybean. It is a saturated fatty acid, which is used for the production of detergents and lubricants, and was discovered to modulate expression of cyclooxygenase-2, an enzyme pivotal to skin inflammation and reparation.

Citrulline (name derived from citrullus, the Latin word for watermelon, from which it was first isolated) is an amino acid. It is made from ornithine and carbamoyl phosphate in one of the central reactions in the urea cycle. It is also produced from arginine as a by-product of the reaction catalyzed by nitric oxide synthase (NOS) family. Citrulline supplements have been claimed to promote energy levels, stimulate the immune system and help detoxify ammonia (a cell toxin). Citrulline is not involved in protein synthesis. Several pharmacokinetic studies have confirmed that citrulline is efficiently absorbed when administered orally. Oral citrulline could be used to deliver arginine to the systemic circulation or as a protein anabolic agent in specific clinical situations (for example in case of malnourishment), because recent data have suggested that citrulline, although not a component of proteins, stimulates protein synthesis in skeletal muscle through the mammalian target of rapamycin signaling pathway. Citrulline is converted to L-arginine by argininosuccinate synthase. L-arginine is in turn responsible for citrulline's therapeutic effects. Many of L-arginine's activities, including its possible anti-atherogenic actions, may be accounted for by its role as the precursor to nitric oxide (NO).

Methylenetetrahydrofolate reductase (MTHFR) is an enzyme required for the formation of 5-methyltetrahydrofolate (5-MTHF), a form of folate able to cross the blood-brain barrier and which is necessary as a substrate for the remethylation of homocysteine to methionine by methionine synthase. Patients with severe MTHFR deficiency cannot make 5-MTHF and have extremely low levels in the CSF. Only treatment with oral 5-MTHF given as calcium mefolinate resulted in an increase in CSF 5-MTHF.

D-ribose, a naturally occurring pentose carbohydrate, and a key component in the adenosine triphosphate (ATP) molecule. D-ribose was studied for congestive heart failure. In addition was discovered, that D-ribose significantly reduced clinical symptoms in patients suffering from fibromyalgia and chronic fatigue syndrome. Recently was published an article where were described, that d-Ribose reacted with the N-terminal valinyl residues of hemoglobin (Hb), thus producing glycated hemoglobin (HbA1c). It is known, that HbA1c is the most important marker of hyperglycemia in diabetes mellitus, which prompts future studies to explore whether D-ribose could also lead to diabetic complications.

D-mannose is a simple sugar found naturally in fruits such as cranberries and pineapples. Unlike many sugars, it is not metabolised or stored in the liver. Much of it is excreted in the urine, where it interferes with particle attachment and prevents certain kind of bacteria from sticking to the walls and causing infection. Mannose supplement is also indicated for treatment of carbohydrate-deficient glycoprotein syndrome, however clinical trials failed to prove its efficacy.

DB00144 (1-propionyl-2-butyl phosphatidylserine) is a phosphatidylserine derivative. It consists of a propionic and butyric acid residues attached in ester linkage to the first and second carbon of glycerol and serine attached through a phosphodiester linkage to the third carbon of the glycerol. DB00144 is not found in natural sources of phosphatidylserine, which contain fatty acids with a length of 20-22 carbon atoms. DB00144 was detected as one of the cellular metabolites in murine myocardium.
