Core Defense Vitamin D&K

Vitamin D deficiency is the most common micronutrient gap in the training population. Most athletes don't know they have it until performance starts to slip.

Vitamin D3 isn't just a bone vitamin. It's a signaling compound that touches immune function, muscle function, healthy testosterone production, and the mental performance that hard training and demanding environments require.* D3 without K2 is only half the protocol — Vitamin K2 MK-7 directs the calcium D3 mobilizes into bones and teeth where it belongs, rather than soft tissue where it doesn't.*

CORE DEFENSE VITAMIN D&K delivers 125mcg (625% DV) of Vitamin D3 — a full-dose protocol for the athlete who needs to restore and maintain performance-supportive levels.* Paired with 100mcg of Vitamin K2 MK-7 for synergistic calcium directionality and 210mg of Calcium as the structural building block.* 60 servings. NSF Certified. This is the D&K protocol done right.

Deficiency is a performance variable. Address it.

My vitamin D was critically low at my last blood test. Within eight weeks on Core Defense my levels increased to optimal range and I noticed the difference in my energy, mood, and immune function much sooner than that. This is a properly dosed product.

I work night shifts and my sun exposure is minimal. My immune health was consistently suffering. Core Defense Vitamin D and K addressed that directly and my sick days have dropped to nearly zero since I started. The K2 pairing makes the dosing correct.

My functional medicine doctor reviewed the Core Defense formula and specifically called out the K2 and D3 ratio as correctly balanced for absorption and bone health. My calcium utilization is better and my immune function has measurably improved.

At 58 years old my bone density and immune health are serious priorities. Core Defense gives me clinically relevant doses of D3 and K2 in a properly combined formula. My next DEXA scan showed stable bone density for the first time in four years.
