Safrel Vitamin K2 (MK7) 120 mcg + D3 5000 IU Supplement, Supports Bone, Immune & Heart Health, Non-GMO, 120 Capsules

Key Health Benefits

• Bone Support: Vitamin D3 helps your body absorb calcium, while K2 directs that calcium into bone tissue, contributing to strong, healthy bones.*
• Immune Function: Vitamin D3 plays a role in normal immune cell function, helping to support your body's natural defenses.*
• Heart Health: By guiding calcium away from soft tissues and into bones, K2 supports arterial flexibility and overall cardiovascular health.*
• Dental Health: Calcium directed to teeth supports strong enamel and dental integrity.*

Understanding the Synergy: How D3 and K2 Work Together

Vitamin D3 enhances the production of calcium-binding proteins in the intestine, improving calcium absorption. Vitamin K2 activates two key proteins: osteocalcin, which helps bind calcium to the bone matrix, and matrix GLA protein (MGP), which helps prevent calcium deposition in blood vessels. Together, they maintain a healthy calcium balance.

This complementary action is why many health-conscious individuals choose a combined D3+K2 supplement. The ratio in Safrel—5000 IU D3 to 120 mcg K2 MK-7—is a well-studied combination for general wellness support. The MK-7 form has a longer half-life, providing steady support throughout the day.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and vitamin K2 work as a team to optimize your body's calcium metabolism. Vitamin D3 helps your body absorb calcium from the digestive tract, while vitamin K2 (specifically as MK-7) helps direct that calcium to the bones and teeth where it belongs—away from soft tissues like arteries. This synergy makes them a popular combination for bone health, immune function, and cardiovascular wellness.

Safrel combines 5000 IU of vitamin D3 (as cholecalciferol) and 120 mcg of vitamin K2 as menaquinone-7 (MK-7) in a single easy-to-swallow capsule. Each bottle contains 120 capsules, providing a four-month supply when taken as directed.

What to Look For in a D3 + K2 Supplement

When choosing a vitamin D3 and K2 supplement, consider the form and dosage of each nutrient. Safrel uses vitamin K2 as MK-7 (menaquinone-7), which remains active in the body longer than MK-4, allowing for once-daily dosing. The 120 mcg dose is within the range commonly used in research for bone and heart support.

The vitamin D3 is sourced as cholecalciferol, the same form produced by your skin in response to sunlight. The formula is non-GMO and manufactured in the USA in quality-focused facilities. This product is produced in a facility that follows Good Manufacturing Practises.

Recommended Dosage

The suggested serving is one capsule per day, preferably with a meal containing some fat, as both D3 and K2 are fat-soluble vitamins for optimal absorption. Each capsule delivers 5000 IU of vitamin D3 and 120 mcg of vitamin K2 (MK-7). This dosage is suitable for adults looking to maintain healthy Vitamin D levels and support calcium utilization. As with any supplement, consult your health-care professional before starting, especially if you are pregnant, nursing, or have a medical condition.

Frequently Asked Questions

If you are taking medications such as blood thinners (e.g., warfarin), consult your health care provider before use, as vitamin K2 can interact with these drugs.

Can I take this with other supplements?

Yes, this combination pairs well with a calcium or magnesium supplement, but always follow your health care provider's recommendations for your individual needs.
