Sun Coast Sciences D3 Shield - Vitamin D3 5000 IU with K2 MK-7 and Calcium - 60 Vegetarian Capsules

What Makes D3 Shield Stand Out?

Sun Coast Sciences D3 Shield is more than just a vitamin D3 and K2 supplement. It includes BioPerine, a patented black pepper extract that enhances the bioavailability of nutrients, ensuring your body can absorb and utilise the D3, K2, and calcium more efficiently. The capsules are vegetarian-friendly, and the formula is crafted without unnecessary fillers. Each serving provides 5000 IU of D3 (a clinically recommended dose) and 180 mg of calcium carbonate, along with K2 MK-7. This triad ensures you get the most from your supplement routine.

Key Health Benefits

Bone Health: Vitamin D3 contributes to normal absorption and utilisation of calcium and phosphorus, helping maintain normal bones. Vitamin K2 contributes to the maintenance of normal bones, and the added calcium carbonate provides a readily absorbable source of calcium.

Immune Support: Vitamin D3 contributes to the normal function of the immune system, helping maintain a balanced immune response.

Mood and Sleep: Optimum vitamin D levels may help support serotonin production, which influences mood and sleep quality. Many users report brighter moods and more restful sleep.

Heart Health: By activating MGP, vitamin K2 helps direct calcium to bones rather than soft tissues, supporting normal blood clotting and cardiovascular function.

How Vitamin D3 and K2 Work Together

When you consume calcium, vitamin D3 stimulates the production of calcium-binding proteins in the intestines, aiding absorption. Vitamin K2 then activates two crucial proteins: osteocalcin and matrix GLA protein (MGP). Osteocalcin helps bind calcium to the bone matrix, while MGP helps prevent calcium deposition in blood vessels. This synergy is why the combination is often recommended for maintaining strong bones and a healthy heart. D3 Shield undertake the superior MK-7 form of K2, which stays active in the body longer than MK-4, providing sustained support.

Why Take Them Together?

Vitamin D3, or cholecalciferol, helps your body absorb calcium from the diet. However, without vitamin K2, that calcium may end up in soft tissues like arteries instead of bones. Vitamin K2, specifically the MK-7 form, activates proteins that direct calcium to the skeleton and teeth. Taking them together ensures calcium is properly utilised, supporting bone density and cardiovascular health. D3 Shield combines these nutrients in optimum amounts for maximum benefit.

Directions for Best Results

For best results, take one capsule daily with a meal that contains fat, as vitamins D and K are fat-soluble. Consistency is key—regular intake helps maintain steady blood levels. Store in a cool, dry place away from direct sunlight. As with any supplement, consult your health care provider before starting, especially if you are on blood thinners (due to K2) or have other health conditions.

Frequently Asked Questions

Can I take D3 Shield if I'm already taking calcium? Yes, but consider your total calcium intake from diet and supplements. The 180 mg here complements a balanced diet.

Is the K2 form MK-4 or MK-7? It is MK-7, the longer-acting form derived from natto or synthetic sources, preferred for sustained benefits.

Are there any side effects? Most people tolerate D3 and K2 well. Excess vitamin D can lead to high calcium levels, so stick to the recommended dosage. Consult a doctor if you have kidney problems or take warfarin.
