Sn-2 DHA Algal Oil
SN-2 DHA Algal Oil is a regiospecifically structured triglyceride in which docosahexaenoic acid is preferentially esterified to the central (sn-2) position of the glycerol backbone, rather than the random distribution seen in conventional algal DHA oils.
The sn-2 positioning mimics the natural distribution of DHA in human breast milk and is the premium DHA format for second-generation infant and follow-on formula systems.
We source bulk Sn-2 DHA Algal Oil from top China manufacturers for our partners. The manufacturer is in Hubei. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
SN-2 DHA Algal Oil is differentiated from conventional algal DHA by its regiospecific fatty acid distribution rather than by total DHA assay.
The signature specification is the proportion of DHA at the sn-2 position, typically reported at 55 to 80 percent of total DHA, compared with roughly 33 percent for randomized triglycerides.
Standard infant-format grade delivers 35 to 45 percent total DHA with a defined sn-2 enrichment factor and parallel low-EPA specification.
High-purity grade reaches 45 to 55 percent total DHA with comparable sn-2 enrichment, used in premium toddler and growing-up milk systems.
Both conventional and organic-certified variants exist, and the oil routinely carries non-GMO Project, halal, kosher, and vegan certifications.

How We Help Source Sn-2 DHA Algal Oil
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Sn-2 DHA Algal Oil out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Sn-2 DHA Algal Oil together with other ingredients such as DHA, DHA Algal Oil and Mct into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
SN-2 DHA Algal Oil is governed by the same regulatory frameworks as conventional algal DHA, with additional novel food considerations in some jurisdictions for the structured triglyceride form.
In the European Union the underlying algal DHA holds authorised novel food status under Regulation (EU) 2015/2283, and structured triglyceride variants are typically supported by additional safety dossiers under the same regulation.
The U.S. Food and Drug Administration has accepted GRAS notifications for structured DHA triglycerides intended for infant formula and general food use.
EFSA authorised health claims for DHA covering brain function, vision, and infant development apply to the structured oil on the same terms.
Codex Alimentarius infant formula standards permit structured DHA oils as optional ingredients subject to the same compositional and contaminant limits as conventional DHA.
Manufacturing Process
Production begins with conventional algal DHA oil from Schizochytrium, Aurantiochytrium, or Crypthecodinium cohnii fermentation, refined to standard infant-grade purity.
The oil is then enzymatically restructured using an sn-1,3 regiospecific lipase, most commonly an immobilized lipase from Rhizomucor miehei or Thermomyces lanuginosus, which selectively hydrolyses the outer positions of the triglyceride.
Free fatty acids are liberated from the sn-1 and sn-3 positions, separated from the diglyceride intermediate by short-path distillation, and the diglyceride is then re-esterified with a tailored mixture of medium-chain or oleic-rich fatty acids to give a structured triglyceride with DHA concentrated at the sn-2 position.
The restructured oil moves through final molecular distillation to remove residual free fatty acids and lipase-derived byproducts, followed by bleaching, deodorisation, and antioxidant stabilisation.
Quality control routinely includes pancreatic lipase positional analysis or chiral-phase HPLC to confirm the sn-2 DHA enrichment specification.
