Product Description

Transparent Labs Vitamin D3 + K2 delivers 5,000 IU of plant-based D3 plus 100mcg of K2 that work together to optimize how your body uses calcium.

Transparent Labs Vitamin D3 + K2 supports bone density, immune function, and muscle performance—three foundations of consistent training for endurance athletes.

Why Vitamin D3 + K2 Matters

The D3 + K2 combination addresses a critical gap: D3 alone can increase calcium absorption, but without K2 to direct that calcium properly, it may deposit in soft tissues rather than bones. K2 activates proteins that ensure calcium strengthens your skeleton instead of stiffening your arteries—critical for cardiovascular health during intense training.

The Performance Foundation – D3 enhances calcium absorption while K2 directs that calcium to your bones instead of your arteries. This partnership supports bone density under training stress, helps maintain immune function during high-volume periods, and contributes to muscle strength and recovery. Research shows athletes with optimal vitamin D levels demonstrate improved muscle function, faster recovery, and reduced injury risk.

Plant-Based, Athlete-Tested Each softgel provides vegan D3 sourced from lichen (not lanolin) and K2 from chickpeas—no animal derivatives. Informed Choice certified for competitive athletes. The formula includes extra virgin olive oil to maximize absorption of these fat-soluble vitamins.

Why It Matters for Athletes Many endurance athletes run low on vitamin D, especially during winter months or if training indoors. Low D status correlates with increased stress fracture risk, compromised immune function, and reduced muscle strength. Studies show athletes with deficient vitamin D levels experience more musculoskeletal injuries and slower recovery compared to those maintaining optimal levels above 40 ng/mL.

How to Use Vitamin D3 + K2

Take one softgel daily with a meal containing fats (breakfast or lunch works well). Take 1-2 servings depending on your baseline vitamin D status—consider testing your levels to determine optimal dosing. Most athletes benefit from year-round supplementation, with potential increases during winter training blocks.

This isn't just bone health supplementation—it's performance insurance that supports the structural integrity, immune resilience, and muscle function required for long-term training consistency.

Plant-Based, Performance-Tested

Each softgel delivers 5,000 IU of vegan D3 from lichen and 100mcg of K2 (MK-7) from chickpeas. This combination optimizes calcium metabolism—D3 enhances absorption while K2 directs calcium to bones instead of arteries. Includes olive oil for maximum absorption of these fat-soluble vitamins.

The Foundation for Consistency

You won't feel a rush—this works at the foundational level. Over 8-12 weeks of consistent use, athletes with low vitamin D typically report fewer illnesses during training, better recovery between hard sessions, and sustained energy. The real benefit shows in what doesn't happen: fewer stress fractures, less frequent colds, maintained performance through winter training.

Addresses a Common Gap

Research shows up to 77% of athletes have insufficient vitamin D levels, especially indoor athletes and those training through winter. This deficiency correlates directly with increased injury risk, compromised immune function, and reduced muscle strength. D3 + K2 addresses both sides of calcium metabolism—absorption and proper utilization—making it smarter than D3-only supplements.
