NUTRAHARMONY Calcium 1200mg + Vitamin D3 & K2 – 180 Slow‑Release Tablets for Bone & Muscle Support

NUTRAHARMONY Calcium 1200mg + Vitamin D3 + K2 is a slow-release, highly bioavailable calcium supplement that combines calcium citrate and carbonate with vitamin D3, K2, magnesium and black pepper for sustained bone and muscle support in a 180-tablet supply.

This formula merges calcium citrate—recognized for gentle digestion and absorption—with calcium carbonate to boost elemental calcium per dose. Vitamin D3 helps maintain normal calcium metabolism while vitamin K2 supports calcium delivery to bone tissue. Added magnesium and black pepper extract further promote uptake, and the slow-release tablet design is intended for steady availability throughout the day. Manufactured in the USA from globally sourced ingredients, these non-GMO, GMP-produced tablets are presented in an economical 180-count bottle for daily use.

How does this calcium blend differ from single-source supplements?

The product pairs calcium citrate and calcium carbonate to balance absorbability and elemental calcium content. Citrate is easier on an empty stomach, while carbonate provides higher calcium by weight, making the combination versatile for varied diets and digestive needs.

• Calcium citrate for superior absorption, especially with lower stomach acid.
• Calcium carbonate for higher calcium concentration per tablet.
• Vitamin D3 included to support calcium utilization.
• Slow-release formulation for steadier blood levels across the day.

What role do vitamin D3, K2, magnesium, and black pepper play?

Vitamin D3 assists the body’s normal use of calcium, while vitamin K2 helps direct calcium to bone rather than soft tissues. Magnesium contributes to bone structure and supports muscle function, and black pepper extract (piperine) is used to enhance absorption of co-nutrients.

• Vitamin D3 supports calcium uptake and normal bone metabolism.
• Vitamin K2 helps with calcium distribution to bone tissue.
• Magnesium complements bone mineral matrix and muscle support.
• Black pepper extract improves overall bioavailability of nutrients.

Is the slow-release tablet design important for everyday use?

Yes—slow-release tablets are formulated to dissolve gradually, which can reduce digestive upset and maintain more consistent nutrient delivery. For many people, this means fewer spikes in calcium levels and a gentler experience for daily supplementation.

• Gradual dissolution reduces potential stomach irritation.
• Sustained release supports more constant calcium availability.
• Convenient once- or twice-daily dosing depending on personal routine.
• Useful for users who prefer stable nutrient intake over the day.

How is product quality ensured and what certifications matter?

NUTRAHARMONY tablets are manufactured in the USA under GMP standards using globally sourced ingredients. The label notes non-GMO sourcing and routine quality checks during production to help ensure purity and potency across batches.

• Made in the USA with GMP oversight and quality control.
• Non-GMO ingredients and batch testing for consistency.
• Clear ingredient list including citrate, carbonate, D3, K2, magnesium.
• Large 180-tablet count for better value and multi-month supply.

Who is this for: NUTRAHARMONY Calcium 1200mg + Vitamin D3 + K2 is suitable for adults seeking a comprehensive calcium supplement that balances absorption and elemental calcium content. It fits people who want a stomach-friendly option (calcium citrate), prefer steady slow-release dosing, and who value added nutrients—D3, K2 and magnesium—that work alongside calcium. It’s practical for busy adults, older individuals wanting bone-supporting nutrients, or anyone looking to complement dietary calcium intake with a high-count, value-oriented bottle.
