Product Description

Stronger bones. Smarter calcium. Complete daily protection.

SVRx D3+K2 Boost is designed to optimize bone strength and cardiovascular wellness by pairing two essential nutrients that work best together: vitamin D3 and vitamin K2. Vitamin D3 helps your body absorb calcium, while vitamin K2 ensures it’s directed to the bones—where it’s needed most—rather than accumulating in the arteries or soft tissues. This synergy promotes not only skeletal strength but also long-term heart and vascular health.

Bone health is about more than just calcium. Without proper cofactors, calcium can be poorly absorbed or misdirected, potentially impacting both skeletal strength and vascular integrity. That’s why SVRx D3+K2 Boost delivers 3000 IU of vitamin D3 from lichen alongside a dual-spectrum blend of vitamin K2 (MK-4 and MK-7) for complete coverage. Together, these nutrients provide optimal calcium metabolism—strengthening bones while supporting arterial health.

Magnesium glycinate is included as a supportive cofactor for calcium utilization, while our clean, vegan capsule ensures purity and digestibility. Free from allergens and unnecessary additives, this targeted daily supplement is an ideal choice for survivors and anyone seeking to maintain strong bones, flexible joints, and a healthy cardiovascular system.

Directions

SVRx D3+K2 Boost will be added to your PM packet. Take your PM supplement in the evening with a full glass of water and with food.

As with any supplement, first consult your doctor if you have a medical condition or are taking medications. We also do not recommend taking our supplements if you are under the age of 18.

Vitamin K2

Vitamin K2 (as MK-4 & MK-7)

Known For
Bone Health Support, Cellular Health Support, Heart Health Support

Can Be Found In
SVRx Daily II, SVRx Multi Complex

Vitamin K2 is a fat-soluble vitamin essential for bone and cardiovascular health. Unlike Vitamin K1, which is involved primarily in blood clotting, K2 is more effective in activating proteins that regulate calcium deposition in the body. This form of Vitamin K is critical for directing calcium to the bones and teeth where it's needed and away from the arteries, thus helping to prevent arterial calcification and supporting heart health. It is naturally found in fermented foods like natto, cheeses, and some animal products.

Why We Chose It

We chose Vitamin K2 (Menaquinone) for its crucial role in bone and cardiovascular health. Preliminary studies suggest that Vitamin K2 may also positively impact cellular health. Vitamin K2's longer half-life allows it to remain in the bloodstream for an extended period, providing sustained health benefits. Among its subtypes, MK-4 (Menaquinone-4) is particularly effective in supporting bone and cardiovascular health. Despite its shorter half-life, MK-4 is potent at lower doses, which is why we selected it for our supplement formulation.

The Science

Vitamin K2 is best known for its role in bone health. It activates proteins that regulate where calcium ends up in the body, specifically directing it to bones and teeth where it is needed and away from arteries and soft tissues where it can be harmful. One of the primary proteins activated by Vitamin K2 is osteocalcin, which binds calcium to the bone matrix, ensuring proper bone mineralization and strength. Studies have shown that adequate intake of Vitamin K2 may help improve bone density. Additionally, Vitamin K2 has been linked to dental health. By directing calcium to the teeth it helps in the remineralization of enamel, contributing to stronger and healthier teeth.

Vitamin K2 is essential for cardiovascular health, playing a role in supporting arterial elasticity. It activates matrix Gla-protein (MGP), which helps regulate calcium deposition in the arteries. This process aids in maintaining smooth and flexible arteries. Research suggests that adequate intake of Vitamin K2 is associated with cardiovascular benefits.

Vegan Vitamin D3

Vitamin D (as Vitamin D3 cholecalciferol from lichen)

Known For
Bone Health Support, Immune Support, Mood and Stress Support

Can Be Found In
SVRx Daily II, SVRx Multi Complex, SVRx D3+K2 Boost

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that is naturally produced in the skin when exposed to sunlight. It is essential for maintaining healthy bones, supporting the immune system, regulating mood, and promoting heart health. It plays a critical role in calcium absorption and bone metabolism, making it a key nutrient for overall health.

Fun Fact: Vitamin D is one of the few vitamins that the body can produce on its own, but only after exposure to sufficient sunlight- hence why its often called the ‘Sunshine Vitamin’! Unfortunately, over 70% of Americans (yes that includes Floridians!) do not get enough vitamin D.

Why We Chose It

Ensuring adequate Vitamin D levels is essential for cancer survivors, as recent research indicates that insufficient Vitamin D may be associated with an increased risk of mortality from common cancers. In addition to its role in supporting bone health and immune function, Vitamin D may also help improve mood, muscle function, and chronic pain management. Its ability to maintain a healthy inflammatory response further contributes to overall well-being.

The Science

Vitamin D3 plays a crucial role in maintaining bone health. This is because it facilitates the absorption of calcium and phosphorus—the building blocks of our bones and teeth. It promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal bone mineralization. Adequate Vitamin D3 intake is especially important as we age, helping to prevent conditions like osteoporosis and keeping our skeletal system strong and resilient.

In addition to its role in bone health, vitamin D3 plays a vital role in strengthening the immune system. It enhances the pathogen-fighting effects of monocytes and macrophages, white blood cells that are critical to immune defense. It also supports a healthy inflammatory response, which can help protect the body from infections and illnesses.

Vitamin D3 is also known to influence mood and mental health. It is involved in the production of serotonin, a neurotransmitter that regulates mood and may help alleviate feelings of depression and anxiety. Adequate levels of vitamin D3 are associated with improved mood and emotional well-being.
