Algal DHA and ARA: Essential Nutrients for Brain and Eye Development

Algal DHA and ARA: Essential Nutrients for Brain and Eye Development

Algal DHA and ARA are two important long-chain polyunsaturated fatty acids (LCPUFAs) that are naturally found in breast milk. DHA, or docosahexaenoic acid, is an omega-3 fatty acid while ARA, or arachidonic acid, is an omega-6 fatty acid. Both are essential for infant growth and development, particularly of the brain and eyes. They cannot be synthesized by the human body and must be obtained through dietary sources.

Role of DHA in Brain and Eye Development

DHA plays a crucial role in brain development during infancy and childhood. It is a major structural component of grey matter and accumulates rapidly in the brain during the first few years of life. DHA supports neuron and nerve cell growth as well as visual and cognitive functions. Clinical studies show infants and children with adequate DHA levels exhibit advanced problem-solving skills, higher IQ scores, and better hand-eye coordination compared to those with low DHA intake.

DHA is also essential for proper vision. It accumulates in high concentrations in the retina, where it supports cell membrane structure and fluidity. DHA deficiency has been linked to greater risks of nearsightedness, color blindness, and other vision problems. Breastfed infants, who naturally receive abundant DHA from their mothers’ milk, tend to have better visual acuity and development than formula-fed babies lacking adequate DHA supply.

Importance of ARA in Growth and Development

While DHA dominates omega-3 research, Algal DHA and ARA is another crucial fatty acid for infant development. ARA plays important roles in skin health, immune function, and other metabolic processes. It is a key component of cell membranes and precursor to signaling molecules called prostaglandins, which regulate numerous bodily functions.

Adequate ARA intake during infancy supports optimal growth rates. Clinical studies show breastfed babies receiving abundant ARA achieve appropriate weight and height gains more consistently than formula-fed infants with less ARA availability. ARA also aids neurological development and cognitive performance. Proper ARA levels promote cell communication in the brain and support synaptic plasticity important for learning, memory, and higher-order thinking skills.

Sources of Algal DHA and ARA

Traditionally, the primary dietary source of DHA and ARA is breast milk or fish, egg, and meat sources derived from marine life. However, vegetarian/vegan mothers and infants lacking access to seafood cannot obtain these nutrients from conventional foods. Here is where algal oils become beneficial:

- Algal DHA and ARA are sourced from microalgae through advanced fermentation and harvesting techniques. Unlike fish oils, algal versions are free of pollutants, ocean contaminants, and other impurities that could pose health risks.

- Multiple clinical studies confirm algal DHA and ARA are as well-tolerated and absorbed by the body as fish oil-derived versions. Algal forms provide a sustainable, vegan-friendly source of these critical fatty acids.

- Enriched infant formulas containing them in levels similar to breast milk have been shown to promote healthy growth, vision, cognition, and overall development comparable to solely breastfed babies.

Regulation in Infant Nutrition

Given the crucial roles of DHA and ARA in infant brain and eye development, major global health organizations endorse their inclusion in infant formulas:

- The Food and Drug Administration permits DHA and ARA enrichment of infant formulas to levels matching the average fatty acid composition of breast milk.

- The European Food Safety Authority and World Health Organization also recommend routine DHA and ARA supplementation for all formula-fed babies.

- Leading pediatric associations encourage mothers choosing formula to select versions enriched with them to better support growth and neurodevelopment comparable to breastfed infants.

Ongoing Research on Algal DHA and ARA Benefits

While established guidelines advise DHA and ARA inclusion in infant formulas, ongoing research continues expanding our understanding of these fatty acids’ impacts:

- Recent long-term cohort studies associate higher levels of formula DHA and ARA with improved cognitive test scores, language skills, and academic performance in later childhood compared to unenriched formula.

- Trials investigating DHA and ARA effects on preterm infant brain development indicate they may help reduce risks of neurodevelopmental disabilities like cerebral palsy.

- Emerging evidence suggests adequate DHA and ARA during pregnancy and lactation may safeguard against postpartum depression in mothers and eczema/allergies in children.

- As understanding of fatty acid roles in immunity and chronic disease prevention expands, scientists exploring links between early-life DHA/ARA intakes and later-life metabolic health outcomes like obesity and diabetes.

algal DHA and ARA provide essential fatty acids that cannot be synthesized by humans but serve critical developmental functions during infancy and beyond. By ensuring formula supplies DHA and ARA at breast milk-similar levels, algae-derived versions help support formula-fed babies’ optimal growth, brain and eye development on par with breastfed infants. Continued research will further illuminate DHA and ARA’s long-term health impacts.
