Recent Advances in the Novel Formulation of Docosahexaenoic Acid for Effective Delivery, Associated Challenges and Its Clinical Importance

Prenatal Supplementation of Docosahexaenoic Acid for the Management of Preterm Births: Clinical Information for Practice

Unhealthy pregnancy and the resultant abnormalities in newborns exhibit a significant drawback. Each year, an estimated 15 million babies are born prematurely, accounting for the majority of deaths among children under the age of 5. India accounts for about a quarter of all preterm birth (PTB) incidences, with few therapeutic options available. However, research shows that consuming more marine foods (rich in omega-3 fatty acids (Ω-3), particularly Docosahexaenoic acid (DHA), helps to maintain a healthy pregnancy and can manage or prevent the onset of PTB and its accompanying difficulties. Present circumstances raise concerns about the use of DHA as a medication due to a lack of evidence on the dosage requirements, safety profile, molecular route, and commercially accessible strength for their therapeutic response. Several clinical experiments have been done over the last decade; however, the mixed outcomes have resulted in discrepancies. Most scientific organizations suggest a daily DHA consumption of 250-300 mg. However, this may differ from person to person. As a result, before prescribing a dosage, one should check the DHA concentrations in the individual's blood and then propose a dose that will benefit both the mother and the unborn. Thus, the review focuses on the favourable benefits of Ω-3, particularly DHA during pregnancy and postpartum, therapeutic dose recommendations, safety considerations, particularly during pregnancy, and the mechanistic pathway that might prevent or reduce the frequency of PTB accidents.

Olive oil and oleic acid-based self nano-emulsifying formulation of omega-3-fatty acids with improved strength, stability, and therapeutics

AIM

To develop, characterise, and optimise SNEDDS formulation to enhance organoleptics, bioavailability, physical & oxidative-stability, and extend shelf-life of pure Ω-3-fatty acids oil for use in the food fortification industry as nutraceuticals.

METHODS

SNEDDS formulations were prepared using a simple stirring technique and optimised based on in-vitro characterisation.

RESULTS

The optimised SNEDDS formulation (F3) had a mean diameter of 52.9 ± 0.4 nm, PDI of 0.229 ± 0.02, zeta potential of -17.3 ± 0.1 mV, cloud temperature of 92 ± 0.2 °C, self-emulsification time of 50 ± 0.2 sec, and stable under accelerated stability conditions. Intestinal permeability study on rat ileum depicted absorption of 88.5 ± 0.2% DHA at 5 h for F3 formulation in comparison to 61.5 ± 0.2% for commercial counterpart. F3 formulation exhibited better therapeutics for melamine-induced cognitive dysfunction.

CONCLUSIONS

The developed Ω-3-loaded SNEDDS heralds the future for an efficacious, safer, and higher strength formulation intended as a better substitute for currently available formulations.
