Marketing Claims Vs. Reality
Supports bone health.
Vitamin D is needed to absorb calcium, and MK-7 at 180 mcg a day slowed bone loss in postmenopausal women over three years (Knapen 2013). This product has 100 mcg.
Supports immune health.
Vitamin D is part of normal immune function; benefits are clearest when levels were low to begin with.
Plant-based D3.
The panel lists D3 from lichen, and the jar is Certified Vegan.
What Our Test Actually Found
Vegan D3 is real D3
Lichen D3 is cholecalciferol, the same molecule as lanolin D3. Vegans used to be limited to D2, which raises vitamin D levels less well (Tripkovic 2012).
A sensible daily dose
2,500 IU sits between the usual 600 to 800 IU recommendation and the 4,000 IU upper limit. Test your 25(OH)D level after about eight weeks if you want to know where you land.
K2 is helpful, not trial-strength
The bone trial behind MK-7 used 180 mcg a day for three years (Knapen 2013). 100 mcg is a reasonable amount alongside D3, but it is not the trial dose.
Full analysis: all pros & cons (8), buy if / skip if
- Vegan D3 from lichen
- K2 as MK-7 in the same softgel
- 2,500 IU, under the upper limit
- In coconut MCT oil for absorption
- K2 below the 180 mcg trial dose
- Contains coconut
- Testing lab not named

- You are vegan or vegetarian and want D3, not D2
- You want D3 and K2 in one softgel
- You want a daily dose under the 4,000 IU upper limit
- You take warfarin or another vitamin K antagonist: K2 interferes, talk to your doctor
- You are allergic to coconut
- You want the full 180 mcg K2 trial dose
D3 is the form that raises vitamin D levels best (Tripkovic 2012), and this one is plant-based. 2,500 IU a day suits maintenance; K2 adds the bone-directed partner, though at a lower dose than the main K2 trial.
Most vitamin D3 is made from lanolin, the grease in sheep's wool, so it is not vegan. This softgel uses D3 from lichen (Vegadelight), the same molecule from a plant source, and pairs it with 100 mcg of vitamin K2 as MK-7 from chickpea. One softgel gives 2,500 IU, a moderate daily dose that stays under the 4,000 IU upper limit, in coconut MCT oil so the fat-soluble vitamins absorb. The K2 dose is below the 180 mcg that slowed bone loss in a three-year trial in postmenopausal women (Knapen 2013).
The pick for women who want D3 + K2 without animal sources
Take one softgel a day with a meal. If you take a blood thinner such as warfarin, talk to your doctor before taking any K2. Pregnant women should agree the dose with their clinician.
If This Doesn’t Fit — Try These
01Thorne Vitamin D + K2 Liquid
If you want a verified label (NSF/ANSI 173 contents certification), prefer a titratable liquid, or need to dial precisely into the 1,000-2,000 IU pregnancy/maintenance window, Thorne is the premium pick.
04Sports Research D3 + K2
Our bone-density pick for the female audience, because bone density is the headline use-case and this is the cleanest single-bottle way to get D3 + the K2 MK-7 cofactor that actually routes calcium where you want it.
06Nordic Naturals Vitamin D3 1,000 IU
Promoted on a women's list because pregnancy and preconception are exactly where the obstetric-consensus 1,000-2,000 IU/day range matters — and 5,000 IU repletion bottles are the wrong tool for that phase.
Quick Answers
Is Sports Research Vegan D3 really vegan?
Yes. The D3 comes from lichen, the K2 from chickpea, and the jar is Certified Vegan. Most other D3 comes from sheep's wool lanolin.
Is 2,500 IU of vitamin D a day safe?
For most adults, yes: it is below the 4,000 IU upper limit. Pregnant women and people with kidney disease should agree the dose with their doctor.
Why take K2 with vitamin D?
Vitamin D raises calcium absorption; K2 activates proteins that bind calcium in bone. In postmenopausal women, 180 mcg of MK-7 a day slowed bone loss (Knapen 2013).
Can I take it with blood thinners?
Not without your doctor if you take warfarin or another vitamin K antagonist, because K2 can change how they work.
