Superior Source Vitamin K2 MK-7 (Menaquinone-7) 100 mcg Sublingual Tablets - Bone and Heart Support - 60 Tablets

The Advantage of Sublingual Delivery

Many vitamin supplements require digestion before they can be absorbed, but sublingual tablets offer a more direct route. By placing a tablet under your tongue, the active ingredients pass straight into the bloodstream through the mucous membranes, bypassing the digestive system. This is particularly beneficial for individuals with digestive issues or those who have undergone bariatric surgery. Superior Source have developed their Vitamin K2 MK-7 100 mcg sublingual tablets to provide rapid and efficient delivery of this essential nutrient.

What Makes This Vitamin K2 MK-7 Supplement Unique?

Vitamin K2 is an essential nutrient that helps direct calcium to bones and teeth while keeping it away from soft tissues like arteries. Superior Source Vitamin K2 MK-7 delivers 100 mcg of menaquinone-7 per sublingual tablet, a form known for its prolonged activity in the body. The sublingual delivery system ensures fast absorption directly into the bloodstream, making it ideal for those with digestive concerns or bariatric patients who may have reduced nutrient absorption. Manufactured in a family-owned facility since 1998, each tablet is designed for convenience and efficacy.

Understanding Vitamin K2: MK-7 vs. MK-4

Vitamin K2 exists in several forms, the most common being MK-4 and MK-7. MK-4 has a short half-life and is typically found in animal-based foods, while MK-7, sourced from natto (fermented soya beans), remains active in the body much longer—up to 72 hours after a single dose. This allows for once-daily supplementation with consistent levels. Superior Source use MK-7 (menaquinone-7) to provide sustained support for your body's calcium management system. The 100 mcg dose aligns with amounts studied in clinical research for bone and cardiovascular health.

Who May Benefit from Vitamin K2 Supplementation?

Individuals who may particularly benefit include those with limited intake of fermented foods like natto, older adults (as K2 production declines with age), people on blood-thinning medications (consult a health care professional first), and anyone taking high-dose Vitamin D or calcium supplements without K2. Bariatric patients often have nutrient malabsorption, making the sublingual form an ideal choice. If you follow a plant-based diet, note that MK-7 from natto is vegan-friendly.

Key Benefits of Vitamin K2 MK-7

• Supports bone health: Vitamin K2 activates osteocalcin, a protein that binds calcium to the bone matrix, contributing to bone density and strength.
• Aids healthy heart function: By helping to prevent calcium deposition in arteries, K2 supports arterial flexibility and cardiovascular health.
• Works synergistically with Vitamin D and Calcium: While Vitamin D enhances calcium absorption, K2 ensures that calcium is directed to the bones where it belongs, not to soft tissues.
• Promotes dental health: Adequate K2 may support tooth remineralisation and gum health.

How to Incorporate Vitamin K2 into Your Routine

Take one sublingual tablet daily, preferably with a meal containing fat to enhance absorption (Vitamin K2 is fat-soluble). Place the tablet under your tongue and allow it to dissolve completely. Avoid swallowing whole. For best results, combine with a balanced diet rich in leafy greens and a Vitamin D supplement. Always consult your health care provider before beginning any new supplement regimen, especially if you are on medications like warfarin or have kidney issues.

Safety and Quality Considerations

Superior Source has been formulating sublingual vitamins since 1998 in their own manufacturing facility. Each batch undergoes quality control testing to ensure potency and purity. The product is free from common allergens and is non-GM. Vitamin K2 is generally well-tolerated, but excessive intake may interact with anticoagulant medications. Symptoms of too much vitamin K are rare but can include flushing or gastrointestinal upset. Stick to the recommended dosage unless directed by your doctor.

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
