DHA

Docosahexaenoic acid (DHA) is an omega-3 fatty acid that plays a crucial role in maintaining overall health, particularly for the brain, eyes, and heart. It is a key component of cell membranes in the nervous system and retina, and it supports cognitive and visual development in infants. DHA is found in high concentrations in fish oils and certain algae sources, and it can also be obtained through dietary supplements.

Indications

Supporting brain and eye development, particularly in infants and children. Improving cognitive function and memory in adults. Promoting cardiovascular health by reducing triglyceride levels and supporting healthy cholesterol levels. Supporting overall eye health and vision, particularly for those with age-related macular degeneration. Contributing to anti-inflammatory effects, which may benefit conditions such as arthritis.

Dosage

For adults: 250–500 mg per day. For pregnant or breastfeeding women: Up to 300 mg per day. For infants and children: The appropriate dosage varies with age and should be discussed with a pediatrician.

Contra-Indications

Allergy to fish or seafood may contraindicate fish-based DHA supplements. Some individuals may experience gastrointestinal discomfort or other allergic reactions.

Special Precautions

Pregnant and breastfeeding women should consult with a healthcare provider before taking DHA supplements to determine appropriate dosage and ensure safety. Individuals on anticoagulant medications should use DHA supplements with caution, as omega-3 fatty acids may increase bleeding risk. Always seek medical advice before taking DHA supplements if you have underlying health conditions or are taking other medications.

Side Effects

DHA supplements are generally safe, but potential side effects may include: Mild gastrointestinal discomfort such as burping, indigestion, or fishy aftertaste. Allergic reactions in individuals sensitive to fish or other ingredients. High doses may increase bleeding risk, especially in combination with blood thinners.

Drug Interactions

Anticoagulant medications such as warfarin and heparin, as DHA can increase bleeding risk. Certain cholesterol-lowering medications. Other supplements containing omega-3 fatty acids, which could lead to excessive intake.
