I. Source Material: Prioritize Algae Oil DHA

• Safety: Plant-based DHA avoids food chain contamination → no heavy metals. Safe for infants/children.

• Quality Standards: Select strains (Schizochytrium, Ulkenia) cultivated in fully enclosed systems for purity.

II. Purity & Dosage: Ensure Efficacy

• DHA Content: Minimum daily intake ≥100 mg. Choose products with ~100 mg per serving.

• Purity Requirements:

  • National standard (China): ≥35%

  • Recommended: ≥53% for optimal benefits

III. Formula & Additives: Enhance Absorption

• Synergistic Nutrients:

  • DHA ratio ≥1:1

  • Additives like lutein or vitamins for brain–eye synergy

• Avoid Harmful Additives: No artificial flavors, colors, preservatives, or trans fats.

• Preferred Form: Gel capsules (oxygen-proof) to preserve stability.

IV. Safety Certification & Palatability

• Certifications:

  • China “Blue Hat” (health food registration)

  • SGS testing or EU standards (GOED, ISO)

• Child-Friendly Taste: Natural fruit flavors (e.g., strawberry) or odorless, sugar-free capsules/liquids

V. Cost-Effectiveness & Suitability

• Age Appropriateness:

  • 0–6 months: Breast milk/formula only (no supplements)

  • 6+ months: DHA-rich food or supplements as needed

• Budget Consideration: Compare cost per unit (¥1–5/capsule). Avoid overpriced products; focus on high-purity brands.

✅ Summary Recommendations

• Choose algae oil DHA ≥53% purity, additive-free.

• Trust certified brands with third-party lab reports.

• Adjust supplement format (liquid, capsule, chewable) based on age.
