The Problem With Most D3 Supplements
Most traditional D3 comes from lanolin, the grease found in sheep's wool. Before the lanolin is extracted, sheep may be treated through a chemical dipping process. LeafSource® uses pine-sourced D3 instead, so no animal source is needed. Our K2 is a highly stable, tested form that is guaranteed to expiry. Together, they deliver the vitamins your body needs in forms it can recognize and use.
The Science
Two Vitamins, One Critical Partnership.
Vitamin D3 helps your body absorb calcium — but without K2, that calcium can end up in your arteries instead of your bones. Together, D3 and K2 work synergistically: D3 pulls calcium in, K2 (as MK-7) directs it precisely where it belongs.
Real D3+K2 uses Pine D3 — sourced from sustainable pine tree sterols, 100% plant-based and free of pesticides — paired with Pharmaquinone® K2-MK7, the only single-peak, validated all-trans MK-7 on the market.
Two ingredients. One complete formula.
Every ingredient is chosen for a specific reason, at a specific dose. Nothing is filler.
2 drops contains:
- 1,000IU Vitamin D3 per serving (2 drops) — from sustainable pine tree sterols
- 120mcg All-Trans K2-MK7 per serving (2 drops) — high-potency, long-acting, single-peak
- 0 Pesticides, lanolin, or animal-derived ingredients — ever
Plant-Based D3
- Pine D3
- (Cholecalciferol)
- 1,000 IU · from pine
- Most D3 supplements are derived from lanolin — a wax extracted from sheep's wool that can carry pesticide residues. Pine D3 is 100% plant-based, sourced from sustainable pine tree sterols, and certified vegan by the UK Vegan Society.
- How it works: Supports calcium absorption → promotes immune function → maintains bone mineral density · Zero pesticides, zero lanolin
Single-Peak K2
- Pharmaquinone®
- K2-MK7
- 120 mcg · all-trans
- Pharmaquinone® is the purest vitamin K2 available — the only MK-7 with validated 100% isomeric purity according to US Pharmacopeia. Guaranteed to remain single-peak until its expiry date.
- How it works: Activates osteocalcin → directs calcium into bones · Activates Matrix GLA Protein → keeps calcium out of arteries · Long-acting MK-7 stays active for 72+ hours
Why They Work Together
- The D3+K2
- Synergy
- Daily combination
- D3 without K2 is incomplete. Vitamin D3 increases calcium absorption — but without K2, that calcium can accumulate in soft tissues and arterial walls. Real D3+K2 ensures both vitamins work together: D3 brings calcium in, K2 puts it in the right place.
- Combined effect: Enhanced bone density → reduced fracture risk · Cardiovascular protection · Immune system support · Strong teeth

2 drops contain: Vitamin K2 (Menaquinone 7) 120 mcg Vitamin D (Vitamin D3) (Cholecalciferol) 25 mcg (1000 IU). Non-Medicinal Ingredients: Medium chain triglycerides, Mixed Tocopherols concentrate, flavour (natural).

1. Two Drops, Once Daily Two drops deliver one full serving — 1,000 IU of vitamin D3 and 120 mcg of K2 (as MK-7). D3 and K2 are fat-soluble, so take your two drops with a meal that contains some dietary fat for the best absorption. 2. Be Consistent for 30 Days Fat-soluble vitamins build up over time. Most customers notice improvements in energy and immune resilience within 3–4 weeks. Bone density benefits accumulate with consistent daily use. 3. Track How You Feel The clearest early signals are improved mood, better energy on low-sun days, and fewer seasonal colds. Look for 25(OH)D levels moving toward the 40–60 ng/mL optimal range.
