Life Extension Vitamins D and K with Sea-Iodine 5000 IU - Triple-Action Bone, Brain & Thyroid Support

Life Extension has been a pioneer in science-backed nutritional supplementation since 1980, earning the trust of healthcare professionals worldwide. Their Vitamins D and K with Sea-Iodine™ delivers a clinically researched combination of 125 mcg (5,000 IU) vitamin D3, 2,100 mcg vitamin K (three bioactive forms), and 1,000 mcg iodine in a single, convenient capsule—now available across Bangladesh at ৳2,950 for 60 capsules. This triple-nutrient formula addresses three critical health gaps common in South Asian diets: limited sun exposure (vitamin D deficiency), insufficient leafy greens and fermented foods (vitamin K shortfall), and low seafood consumption (iodine insufficiency). For health-conscious Bangladeshis seeking comprehensive bone, cardiovascular, thyroid, and cognitive support, this formula represents pharmaceutical-grade quality at transparent pricing.

What Makes Life Extension's D3 + K + Iodine Formula Different from Single-Nutrient Supplements?

Most vitamin D supplements on the Bangladesh market provide D3 alone, missing a critical synergy: vitamin K directs calcium into bones while preventing arterial calcification—a concern when taking higher-dose vitamin D. Life Extension's formula solves this with 2,100 mcg of vitamin K activity from three scientifically validated forms: K1 (phytonadione), K2 as MK-4 (menaquinone-4), and K2 as MK-7 (trans menaquinone-7 from K2VITAL®). The MK-7 form remains active in the body for up to 72 hours, providing sustained calcium regulation, while MK-4 supports rapid tissue-specific benefits in bones and arteries. The inclusion of 1,000 mcg iodine from Sea-Iodine™ Complex (organic kelp and bladderwrack extracts plus potassium iodide) addresses thyroid health—a growing concern in Bangladesh where iodized salt consumption has declined among health-conscious consumers avoiding excess sodium. This triple-action approach is backed by Life Extension's commitment to clinical research, with every batch tested for purity and potency. Manufactured in GMP-certified facilities in the USA, this formula is Non-GMO verified and uses patent-protected K2VITAL® for superior bioavailability. Unlike generic vitamin D pills, this comprehensive formula supports multiple interconnected health systems in one evidence-based supplement.

Key Health Benefits & Why Bangladesh Needs Vitamin D, K & Iodine

Bangladesh faces a silent epidemic of vitamin D deficiency despite abundant sunlight—cultural dress codes, indoor work environments, and pollution-reduced UV exposure mean up to 70% of urban Bangladeshis have suboptimal vitamin D levels. This formula's 125 mcg (5,000 IU) of vitamin D3 helps support:

• Cognitive Function: Healthy vitamin D levels correspond with better memory, focus, and mental clarity—critical for students, professionals, and aging adults
• Bone Density: Works synergistically with vitamin K to facilitate calcium absorption into the bone matrix, helping maintain strong bones and teeth (especially important for postmenopausal women and older adults)
• Immune System Health: Supports the body's natural defense mechanisms and promotes a healthy inflammatory response
• Cardiovascular Health: Helps maintain healthy blood pressure already within normal range by supporting healthy renin levels and encouraging healthy endothelial function

The vitamin K complex (1,000 mcg K1 + 1,000 mcg MK-4 + 100 mcg MK-7) provides dual cardiovascular and skeletal benefits by:

• Inhibiting calcium buildup in arteries (helps prevent arterial stiffness)
• Activating osteocalcin, a protein that binds calcium to bone tissue
• Supporting healthy blood clotting function

The 1,000 mcg iodine from Sea-Iodine™ addresses a critical gap in many Bangladeshi diets—particularly among vegetarians, vegans, and those reducing table salt intake. Iodine is essential for:

• Production of thyroid hormones T3 and T4, which regulate metabolism, energy levels, and body temperature
• Supporting healthy cognitive development and neurological function
• Maintaining healthy breast and prostate tissue

Traditional Bangladeshi diets rich in rice, lentils, and vegetables often lack sufficient iodine, vitamin K2 (found mainly in fermented foods and animal products), and bioavailable vitamin D—making supplementation a practical solution for comprehensive health support.

How to Use Life Extension Vitamins D and K with Sea-Iodine - Dosage & Timing

Recommended dosage: Take one (1) capsule once daily with food, or as recommended by a healthcare practitioner.

Best time to take: With your largest meal of the day (breakfast or lunch) to maximize absorption of fat-soluble vitamins D and K. Taking with food that contains some dietary fat (such as eggs, nuts, or cooking oil) enhances bioavailability by up to 50%.

For those new to vitamin D supplementation: Consider getting a baseline 25-hydroxy vitamin D blood test before starting, then retest after 3 months to assess your optimal dosage. Target blood levels should be 50–80 ng/ml (125–200 nmol/L). If your current multivitamin already provides 25–75 mcg (1,000–3,000 IU) of vitamin D, this supplement can help you reach optimal levels.

Storage: Store in a cool, dry place away from direct sunlight. Keep bottle tightly closed. Refrigeration is not necessary.

Duration of supply: Each bottle contains 60 capsules, providing a 2-month supply at the recommended one-capsule-per-day dosage.

Important Precautions & Who Should Consult a Doctor First

Do not use without medical supervision if:

• You have hypercalcemia (high blood calcium levels)
• You have a thyroid condition (hyperthyroidism, hypothyroidism, thyroid nodules) or are taking antithyroid medications (such as methimazole or propylthiouracil)
• You are taking anticoagulant medications (warfarin, heparin) or antiplatelet drugs (aspirin, clopidogrel) due to vitamin K's role in blood clotting
• You have a bleeding disorder
• You are pregnant, nursing, or planning pregnancy
• You are under 18 years of age

Monitoring recommendation: Individuals consuming more than 50 mcg (2,000 IU) per day of vitamin D from all sources (diet + supplements) should periodically obtain a serum 25-hydroxy vitamin D measurement. Do not exceed 250 mcg (10,000 IU) per day unless recommended by your doctor.

Drug interactions: Vitamin K can interfere with blood-thinning medications. If you are on anticoagulant therapy, consult your healthcare provider before use, as dosage adjustments may be necessary.

Price, Value & Availability in Bangladesh

Transparent Pricing for Authentic Quality

Current price: ৳2,950 for 60 capsules (2-month supply)

Cost per serving: ৳49.17 per day (less than the cost of a cup of tea at a Dhaka cafe)

Value comparison: While single-nutrient vitamin D supplements may cost ৳1,500–2,200 in Bangladesh, they lack the synergistic benefits of vitamin K and iodine. Buying these three nutrients separately would cost ৳4,500–6,000 and require taking three different pills daily. This formula consolidates triple-action health support into one capsule at a cost-per-day that reflects genuine USA-manufactured quality—not locally repackaged imports of unknown origin. The inclusion of patent-protected K2VITAL® (which alone costs more to source than many generic vitamin D supplements) and organic sea-sourced iodine justifies the premium over basic supplements, offering pharmaceutical-grade purity for health-conscious Bangladeshis who prioritize authenticity over price alone.
