The months when sunlight isn't enough
For most people, sun exposure alone isn't reliable enough to maintain optimal D3 levels year-round. A daily spray keeps levels consistent - whatever the season, wherever you are.
"Vitamin D3 and K2 are among the most researched nutrient partnerships in modern science - and among the most commonly taken separately, when their real power lies in being taken together"

LYL sunD3 Vitamin D3 + K2
Natural D3 & K2 Oral Spray
Third Party Verified
Sugar Free
Daily Oral Spray
You take your D3. Good. But if K2 isn't part of the equation, you're only telling half the story. LYLsunD3 VITAMIN D3 + K2 gives you both - in one effortless daily spray.
D3 WITHOUT K2 IS AN UNFINISHED SENTENCE
Most people supplement D3. Far fewer know that K2 is the partner that completes the job - guiding calcium to your bones, not your soft tissue. We put them both in the same bottle, so you don't have to think about it.
CLEAN BY DESIGN - NOT BY ACCIDENT
No sugar, no sweeteners, no fillers. Verified by The Good Pill Co™, every single batch.
WHY A SPRAY?
Because fat-soluble vitamins like D3 and K2 absorb better in an oil base - and an oral spray delivers them directly, without the delay of a capsule breaking down. Faster, cleaner, more efficient. And yes, easier to take too.

Key Ingredients
Our Clinical Studies
LYLsunD3 Vitamin D3 + K2 - The Science Behind the Duo
Two nutrients. Six proven benefits. One daily spray.
Stronger bones - the full picture¹
What it does: D3 increases calcium absorption. K2 (MK-7) activates the proteins that direct that calcium into bone tissue - completing a process D3 alone cannot finish.
Why it matters: Bones aren't built by one nutrient. They're built by nutrients working in sequence. This formula covers both steps - so your calcium actually ends up where you want it.
Immune resilience, year-round²
What it does: Vitamin D3 contributes to the normal function of the immune system.
Why it matters: D3 deficiency is one of the most common nutritional gaps in Northern Europe - especially in winter. A daily spray keeps your levels consistent, not just seasonal.
Healthy teeth and muscles³
What it does: Vitamin D contributes to the maintenance of normal teeth and normal muscle function.
Why it matters: Teeth and muscles depend on the same calcium metabolism D3 + K2 supports. One formula - broader impact than you might expect.
Balanced calcium levels⁴
What it does: Vitamin D helps maintain normal blood calcium concentration.
Why it matters: Calcium balance isn't just about bones - it affects muscle contraction, nerve signaling and heart rhythm. D3 helps keep the whole system in check.
Cellular health⁵
What it does: Vitamin D plays a role in the process of cell division.
Why it matters: Cell division is how the body repairs and renews itself. D3's role here is one of its least talked-about but most fundamental contributions to long-term health.
Normal blood clotting (K2)⁶
What it does: Vitamin K2 contributes to normal blood coagulation.
Why it matters: K2 is far more than a bone nutrient. Its role in coagulation makes it a key player in circulatory health - another reason the D3 + K2 combination is worth taking seriously.
Verified. Every batch.
What it does: The Good Pill Co™ independently tests every batch for potency, consistency and safety.
Why it matters: You don't have to take our word for it. Third-party testing means the dose on the label is the dose in the bottle - always.
¹ EFSA: Vitamin D contributes to normal absorption of calcium and to the maintenance of normal bones. Vitamin K contributes to the maintenance of normal bones.

³ EFSA: Vitamin D contributes to the maintenance of normal teeth and normal muscle function.
⁴ EFSA: Vitamin D contributes to normal blood calcium concentration.
