YesNutri Calcium plus K2 Tablets｜Bone-Targeted Calcium Absorption

Bones function as the body's calcium reservoir and fulfill critical roles in bodily support, limb mobility, and organ protection. Urban populations generally exhibit insufficient calcium intake, and regular dietary intake alone may not meet the body's calcium requirements. YesNutri® Calcium + K2 Tablets incorporates natural eggshell calcium, vitamin K₂, vitamin D₃, magnesium, and zinc. This formulation not only facilitates calcium supplementation but also activates osteocalcin, enabling precise calcium deposition in bones while inhibiting calcium accumulation in blood vessels.

The unique formula further includes patented FruiteX‑B®, turmeric extract, ginger extract, and horsetail extract, which significantly enhance the bioavailability of calcium and vitamin D₃, promote bone mineralization, alleviate muscle discomfort, and improve joint flexibility. Daily supplementation of 1–2 capsules supports targeted calcium incorporation into bone tissue, strengthens bone density, enhances muscle function, and provides comprehensive protection for bone and joint health.

Detailed Information

Attributes of the Bone and Tissue Formation Ingredients

Eggshell Calcium (Natural Calcium Carbonate)
Calcium carbonate extracted from eggshells is a natural source of calcium. Due to its composition being similar to that of our bones and teeth, it enhances absorption and utilization effectively.

• Maintain bone density and protect skeletal and dental health [1, 2]
• Supports blood clotting and helps maintain nerve function and muscle health [19]

Vitamin D3 (Cholecalciferol)
Most individuals spend long periods indoors with limited sun exposure, making vitamin D3 deficiency common. Supplementing with vitamin D3 can help increase intake and improve calcium levels in the body.

• Enhances calcium absorption and optimizes muscle coordination [3, 4]

FruiteX‑B® (Calcium Fructoborate)
A patented vegan mineral complex derived from natural fruits, nuts, and vegetables, providing highly absorbable "boron."

• Enhances bone strength and promotes bone growth [6, 20]
• Facilitates the activation of vitamin D3 [7]
• Improving joint mobility [18]

Vitamin K2 (MK-7)
High absorption rate and highly active K2 type. Activates osteocalcin, precisely directing calcium from the bloodstream into bones and teeth while preventing calcium buildup in blood vessel walls, to promote calcium sequestration into bone. [5]

Magnesium (Magnesium Oxide, Magnesium Citrate, Magnesium Chelate)
Activates vitamin D to promote calcium absorption [7]
Relaxes muscles and prevents cramps [8]

Zinc Monomethionine
High activity and utilization efficiency. Slows down bone resorption and promotes osteoblast formation [9]. Supports collagen synthesis and enhances tissue repair [10].

Copper Gluconate
Promotes collagen synthesis, strengthening joint and bone structure [15]. Maintains bone density [16].

Attributes of the Relieving Joint and Muscle Discomfort Ingredients

Turmeric Extract (contains curcuminoids), Ginger Root Extract (contains gingerols)
Strong anti-inflammatory and antioxidant effects, help to relieves pain and reduces swelling, alleviating joint and muscle discomfort [11, 12, 17].

Horsetail Herb Extract
Rich in silicon, which promotes cartilage and bone health and supports growth and development [13]. High in flavonoids, helping to reduce damage and swelling in joint and bone tissues [14].

Benefits

• Effectively locks calcium into bones [3, 5]
• Maintains bone density [1, 5, 9, 13, 16]
• Slows down bone loss [1, 5, 6, 9, 16]
• Enhance activity capacity [1, 5, 13]
• Supports dental health [2]
• Relieves joint discomfort [6, 11, 14]
• Reduces muscle soreness [8, 12]
• Enhances muscle coordination [4]
• Maintain cardiovascular health [21, 22]
• Maintain immune system [22]

Suitable for

Elderly individuals, Sedentary lifestyle, Office workers, Bone loss/osteoporosis, Joint strain/degeneration, Joint pain/stiffness, Mature women, Unbalanced diet/frequent coffee or tea consumption, Limited sun exposure, Fitness enthusiasts.
