Dosage & timing

Recommended Dosage:

250-500mg combined EPA+DHA daily for general health; up to 1000mg+ DHA for higher omega-3 status or triglyceride goals

Warnings

Strong evidence is for raising omega-3 status; effects on hard cardiovascular endpoints carry the same uncertainty as fish oil
High doses can have a mild antiplatelet effect

Best Time:

With meals

Take with food

Best Form:

Algal DHA oil (or EPA+DHA oil)

Recommended Dosage:

Prescription-only, clinician-titrated, subcutaneous once daily. Diabetes (Victoza): escalate 0.6 → 1.2 → 1.8 mg/day. Weight management (Saxenda): escalate weekly to 3.0 mg/day. DO NOT self-dose.

Warnings

This is a PRESCRIPTION DRUG, not a dietary supplement — use only under a clinician's care for an approved medical indication.
US FDA labeling includes a boxed warning about thyroid C-cell tumors: liraglutide caused these tumors in rodents; relevance to humans is uncertain. Under the US label it is contraindicated with a personal or family history of medullary thyroid carcinoma (MTC) or MEN2. For treatment in Germany or Austria, consult the current EU product information for the exact medicine’s locally approved indications, contraindications and warnings; discuss any thyroid history with the prescriber.
Risk of acute pancreatitis — discontinue and seek care for severe persistent abdominal pain.
Risk of gallbladder disease (gallstones, cholecystitis), particularly with rapid weight loss.
Gastrointestinal adverse effects (nausea, vomiting, diarrhea) are very common, especially during dose escalation.
Weight loss includes loss of lean muscle mass — pair with resistance training and adequate protein.
FDA has warned about COMPOUNDED / grey-market GLP-1 products: risk of dosing errors, impurities, and unapproved salt forms. Use only pharmacy-dispensed product.
Not for cosmetic weight loss without a genuine medical indication.
May increase hypoglycemia risk when combined with insulin or sulfonylureas (dose adjustment needed).

Lipids (2007) · Rct

28-day randomized, placebo-controlled, parallel-group study: two algal DHA oils (DHASCO-T and DHASCO-S) in capsules at 200, 600 and 1,000 mg DHA per day, and an algal-DHA-fortified snack bar, 12 per group. The abstract does not give the placebo group size or the total

Randomized, double-blind crossover of four single high-fat meals in 16 men aged 35-70 with above-optimal fasting triacylglycerol: control oil, plus fish oil (5 g EPA and DHA), plus algal oil (5 g DHA), or high-linoleic oil
