Thorne’s Vitamin D + K2 Liquid promotes bone health, healthy immune function, and cardiovascular health.* The combination of vitamin D3 and K2 provides greater benefits together than either does individually.

Vitamin D3 and K2 work together to benefit bone health, cardiovascular support, and healthy immune function.* Maintaining an optimal level of vitamin D throughout all stages of life helps maintain strong bones and healthy immune function.* Adding vitamin K2 helps move calcium to the bones to protect soft tissues, such as the arteries and kidneys, from calcification.* Combining vitamins D3 and K2 provides greater benefit together than each offers separately.

 Benefits of Thorne’s Vitamin D + K2: 

• Supports a healthy heart and blood circulation*
• Promotes bone health and calcium absorption*
• Benefits immune function*
• The combination provides advanced bone health support*

 Features of Vitamin D + K2: 

• The vitamin K2 in this formula is MK-4, the most clinically studied form of vitamin K
• Vitamin D, in its D3 form, is a more potent and better absorbed form than its D2 form
• The self-dispensing top provides an accurate, safe, and individualized dose by metering individual drops
• Thorne's Vitamin D + K2 Liquid is in medium chain triglyceride oil and preserved with mixed tocopherols

Supports antioxidant defenses, immune function and cellular health‡

Selenium is a natural antioxidant that delays the oxidation of polyunsaturated fatty acids and preserves the elasticity of tissue. Selenium is required for the production of certain prostaglandins, which promote healthy blood flow. Selenium may also help support healthy growth and fertility, as indicated in a research study using a combination of selenomethionine and vitamin E. Selenium also provides support for the immune system. Selenomethionine serves as a storage form of selenium. It is incorporated into proteins and released as the proteins are catabolized.‡

Support for Healthy Respiratory and Immune Function

Zinc Picolinate a highly absorbable essential mineral with a key role in numerous metabolic functions throughout the body as well supporting healthy organs, bones, and connective tissues. Its other critical role is in promoting respiratory and immune health.  By supporting healthy oxidative stress response, zinc also promotes healthy inflammatory markers throughout the body needed for optimal immune and respiratory health.

Clinical evidence and research shows that the ingredients in Zinc Picolinate may:

• Promote respiratory and immune health
• Support healthy oxidative stress response
• Promotes healthy inflammatory markers in the body
• Promote healthy testosterone metabolism
• Support prostrate health
• Support healthy connective tissues
• Support skin health

Supports respiratory function, glutathione production and detoxification*

N-Acetyl-L-Cysteine (NAC) is a derivative of the dietary amino acid L-cysteine. NAC has a high affinity for lung tissue, which it supports through mucolytic and antioxidant action. Due to its sulfur content, NAC is able to disrupt disulfide bonds within mucus, thinning and easing its expulsion. NAC is a free radical scavenger and thus supports epithelial cell health and healthy cilia activity in the respiratory tract. NAC is also a precursor to the antioxidant glutathione, and supplemental NAC increases tissue levels of glutathione. As fundamental components of the immune system, lymphocytes rely on glutathione to function properly. Tissues enhanced with glutathione support overall antioxidant protection and help to maintain a healthy immune response. A multicenter, randomized, double-blind trial with 262 participants indicated that NAC supplementation for six months supported upper respiratory tract and immune system health. A recent meta-analysis of eight double-blind, placebo-controlled trials provided additional support for NAC's ability to support respiratory tract health.*
