Common Deficiency Symptoms

Omega-3 deficiency: dry skin, poor memory, joint stiffness; Vitamin A deficiency: night blindness, dry eyes, frequent infections; Vitamin D deficiency: bone pain, muscle weakness, fatigue; Vitamin E deficiency: nerve damage, muscle weakness, immune impairment

Target Population

Adults and children over 12 seeking to support their immune system, bone health, and heart function, particularly those with low dietary fish intake.

Scientific Evidence Level

Strong

Onset Timeline

Omega-3 blood levels improve within 4-8 weeks of consistent use; Vitamin D serum levels rise within 2-4 weeks; cardiovascular and anti-inflammatory benefits typically observed after 8-12 weeks of regular use

Servings Per Container

Best Time to Take

With meals

Recommended Daily Intake

Omega-3 (EPA+DHA): 250-500 mg/day for general health; Vitamin A: 700-900 µg RAE/day; Vitamin D: 15 µg (600 IU)/day for adults; Vitamin E: 15 mg/day

Upper Tolerable Limit

Vitamin A: 3000 µg/day (adults); Vitamin D: 100 µg (4000 IU)/day (adults); Vitamin E: 1000 mg/day; Omega-3: 3000 mg/day (EPA+DHA combined, per EFSA)

Absorption Enhancers

Take with a fat-containing meal to enhance absorption of all fat-soluble components (Vitamins A, D, E, and omega-3 fatty acids)

Absorption Inhibitors

Very low-fat meals reduce absorption of fat-soluble vitamins and omega-3s; high-dose iron supplements may interfere with Vitamin E absorption; mineral oil laxatives reduce absorption of fat-soluble vitamins

Side Effects

Possible Side Effects

Fishy aftertaste or burping; nausea or loose stools at higher doses; prolonged high-dose Vitamin A intake may cause headache, liver toxicity, or teratogenicity; high-dose Vitamin D may cause hypercalcemia (nausea, weakness, frequent urination)

Toxicity Risk

Medium

Upper Tolerable Limit

Vitamin A: 3000 µg/day (adults); Vitamin D: 100 µg (4000 IU)/day (adults); Vitamin E: 1000 mg/day; Omega-3: 3000 mg/day (EPA+DHA combined, per EFSA)

Safety & Warnings

Contraindications

Hypervitaminosis A or D; hypercalcemia; hypersensitivity to fish/fish products or any component (and avoid use with systemic retinoids due to additive vitamin A exposure)

Pregnancy Safety

Consult Doctor

Breastfeeding Safety

Generally safe at labeled dose (compatible with breastfeeding); avoid excessive vitamin A intake and do not exceed recommended dose

Children Suitability

This specific formulation (Once A Day) is intended for adults; Seven Seas offers separate formulations for children - consult a healthcare provider before use in children

Interactions

Medication Interactions

May enhance the effect of anticoagulant/antiplatelet drugs (e.g., warfarin, aspirin) and blood pressure medications. Do not take with oral retinoids (e.g., isotretinoin) due to increased risk of Vitamin A toxicity.

Supplement Interactions

High-dose Vitamin A from multiple sources (multivitamins, liver supplements) may increase toxicity risk - monitor total intake; concurrent high-dose Vitamin D supplements may cause additive hypercalcemia risk

Synergistic Nutrients

Vitamin D + Calcium + Vitamin K2 for bone health; Vitamin A + Zinc for immune function and vision; Omega-3 EPA/DHA + Vitamin E for cardiovascular protection and antioxidant support

Patient Counseling

Take 1 soft capsule once daily by mouth with a meal (preferably with some fat) to aid absorption of the fat‑soluble vitamins (A, D, E). Do not exceed the recommended dose; avoid taking additional vitamin A/D supplements unless advised, and seek medical advice if pregnant/planning pregnancy or if using anticoagulants/antiplatelets (e.g., warfarin) due to potential bleeding risk and vitamin A safety considerations. Store below 25°C; check the pack expiry (shelf life 36 months from manufacture).
