D3 K2 Magnesium Glycinate - Extra Strength

D3 K2 Magnesium Glycinate - Extra Strength

Still taking Vitamin D by itself? Here's why that's a problem.

Vitamin D3 helps your body absorb calcium - but it doesn't tell that calcium where to go. Without Vitamin K2, calcium can end up depositing in your arteries instead of strengthening your bones. And without Magnesium, your body can't even convert Vitamin D into its active form. It just sits there, doing nothing.

This 3-in-1 formula brings together what nature intended to work together: high-potency D3 to boost calcium absorption, K2 (as MK-7) to direct calcium to your bones, and Magnesium Glycinate to activate your D3 and support restful sleep.*

One bottle. Three essential nutrients. The complete system.

Benefits

Benefits

  Complete Synergy Formula: 10,000 IU Vitamin D3, 200 mcg Vitamin K2 (MK-7), and 200 mg Magnesium Glycinate in every serving—the three nutrients that work together to support calcium metabolism, bone health, and cardiovascular function.* 

  Magnesium That Activates Your D3: All 8 enzymes that metabolize Vitamin D require magnesium as a cofactor. Without adequate magnesium, your D3 supplementation may be less effective. We include 200 mg of highly absorbable Magnesium Glycinate.* 

  K2 Directs Calcium Where It Belongs: Vitamin K2 activates Matrix Gla Protein (MGP) and osteocalcin—the proteins responsible for keeping calcium in your bones and out of your soft tissues. Think of K2 as your body's "calcium traffic cop."* 

  The Sleep-Friendly Magnesium: Unlike oxide or citrate, Magnesium Glycinate is gentle on digestion and known for its calming properties. Many customers notice improved sleep quality within the first week.* 

  Premium Absorption: Oil-based softgels enhance absorption of fat-soluble vitamins D3 and K2. No tablets that sit in your stomach—just smooth, easy-to-swallow softgels that your body can actually use. 

  5-Month Supply: 300 softgels at 2 per serving = 150 days of complete D3+K2+Magnesium support. Real value, not a 30-day bottle that runs out before you notice results.

Every Batch. Tested. Published.

We send every Therexa product to independent, accredited laboratories in the United States for third-party testing. Then we publish the results — not summaries, not badges, the actual reports.

Heavy Metals (Every Batch)

Every batch is screened for arsenic, cadmium, lead, and mercury to ensure safety.

Microbial Contamination (Every Batch)

Every batch is tested for bacteria, yeast, mold, E. coli, Salmonella, and other pathogens.

Identity Verification (Annual)

Each product undergoes annual identity testing to confirm the ingredients match exactly what's on the label.

Why This Matters?

  • The supplement industry is largely self-regulated. Many brands never test their products - or only test once and reuse that report for years.
  • We test every batch for safety. We verify every product annually for identity. And we will show you the results.
  • If a brand won't publish their lab reports, ask yourself what they're hiding.
