Key Benefits of a Complete Senior Multivitamin

As we age, dietary gaps become more common. A targeted multivitamin like Sentry Senior helps fill those gaps and supports vital areas:

• Heart Health: Vitamins B6, B12, and folic acid aid in normal homocysteine metabolism, which is important for cardiovascular function.*
• Eye Health: Lutein and lycopene are antioxidants that help maintain healthy vision as part of a nutritious diet.*
• Bone Health: Calcium and vitamin D3 contribute to maintaining strong bones and teeth.*
• Immune Function: Vitamins C, D, and zinc support a healthy immune system.*
• Energy Metabolism: B vitamins assist in converting food into cellular energy.*

*This product is a natural health product (NHP) that provides nutritional support. Always read the label and follow directions for use. Consult your healthcare practitioner if symptoms persist or worsen.

Top Ingredients to Look For

Choosing a senior multivitamin means paying attention to ingredient forms and levels. Sentry Senior includes:

• Vitamin D3 (Cholecalciferol): 1,000 IU per tablet enhances calcium absorption and immune function. D3 is the preferred form for better utilisation.*
• Vitamin B12 (Cyanocobalamin): 25 mcg (1,042% DV) helps maintain nerve function and red blood cell formation. Older adults often need higher B12 due to reduced absorption.*
• Calcium (Calcium Carbonate): 220 mg per tablet contributes to bone density.*
• Magnesium (Magnesium Oxide): Supports muscle function and bone health.*
• Zinc (Zinc Oxide): Plays a role in immune health and wound healing.*
• Lutein and Lycopene: Carotenoid antioxidants that help protect eye health.*

Sentry Senior is intentionally iron-free, as most adults over 50 do not require supplementary iron unless directed by a physician. This helps avoid potential iron overload.

Who Should Take This Multivitamin?

This multivitamin is designed for adults aged 50 and older who want complete nutritional support in a simple, once-daily tablet. It is particularly suitable for:

• Individuals looking to fill dietary gaps caused by aging or reduced food intake.
• Those prioritising heart, eye, and bone health as part of a proactive wellness routine.*
• People who prefer an iron-free supplement to avoid excess iron.
• Anyone seeking a gluten-free, non-GMO option without artificial flavors or yeast.

As with any supplement, consult your healthcare provider before starting a new regimen, especially if you have underlying health conditions or take medications.

How to Choose the Best Multivitamin for Adults 50+

With many options available, here are factors to consider when selecting a multivitamin for seniors:

• Formulation: Look for a formula that addresses age-specific needs like bone density (calcium, vitamin D), heart health (B vitamins, magnesium), and eye health (lutein). An iron-free option is often recommended for men and postmenopausal women.
• Dosage: A once-daily tablet encourages consistency. Check the % Daily Value to ensure adequate nutrient levels without exceeding tolerable upper limits.
• Third-Party Testing: While not all supplements undergo independent testing, brands with a long history of quality assurance offer added confidence. 21st Century has been in the supplement industry for over 34 years.
• Certifications: Non-GMO and gluten-free certifications are important for those with dietary restrictions or sensitivities.
• Comparability: Sentry Senior is designed to compare with leading brands like Centrum Silver Adults, offering similar active ingredients at a more affordable price point.

Is this multivitamin comparable to Centrum Silver?

Yes. The active ingredients in 21st Century Sentry Senior are similar to those in Centrum Silver Adults, providing comparable nutritional support. However, this product is not manufactured or distributed by Haleon Holdings, LLC, owner of the Centrum trademark.

Why is this formula iron-free?

Most adults over 50 do not need extra iron unless prescribed by a doctor. Excess iron can accumulate in the body and may contribute to oxidative stress. An iron-free formula helps prevent this while still delivering key nutrients.

Each bottle contains 265 tablets. With a recommended dose of one tablet per day, this supply lasts nearly nine months, making it a convenient and cost-effective choice.
