Short answer: NUSAVA’s D3 K2 drops put 5,000 IU of vitamin D3 plus vitamin K2 (MK-4 and MK-7) into an organic, MCT-oil-based dropper — no pills to swallow. The listing holds a 4.5-star average across roughly 14,109 buyer ratings and sits in the top 10 of Amazon’s Vitamin D3 & K2 Combinations category. Buyers pick the liquid format for convenience and dose control; the flavored versions get mixed taste reviews, which is why this spotlight covers the unflavored 2-pack.

Why D3 and K2 Get Sold Together
This is the first question buyers ask, so here’s the plain version of what the labels say:
Vitamin D is the nutrient a lot of adults run low on — it comes from sun exposure and a short list of foods, and plenty of people who work indoors or drive for a living don’t get much of either. Vitamin K2 is paired with D3 in formulas like this one because the two are commonly formulated together in bone- and calcium-focused supplements; the label positions this product around bone, heart, muscle, and immune support.
That’s the manufacturer’s framing, and it’s why “D3 + K2” has become its own category instead of two separate bottles. Whether any supplement is right for you is a conversation for your doctor — what we can do here is tell you how this specific product is built and what buyers report.
What’s in the Bottle, Per the Label
- 5,000 IU vitamin D3 per serving, with vitamin K2 as MK-4 + MK-7.
- MCT oil and omega-3 (chia seed oil) base — D3 is fat-soluble, so liquid formulas are typically delivered in an oil; that’s a formulation fact, not a promise.
- USDA Organic, non-GMO, no fillers per the label; made in the USA.
- Pack of 2 bottles, 2 fl oz total — the listing describes roughly a month of servings per bottle at the labeled dose.
- Unflavored in this listing. The same product family sells flavored versions (pineapple, strawberry, chocolate) under different listings.
The Liquid Question: Drops vs. Pills
Buyers land on this product for format reasons more than anything:
- No swallowing pills. A real and common dealbreaker, especially for people already taking several capsules a day.
- Dose control. A dropper lets a buyer follow their doctor’s dosing guidance more precisely than splitting a fixed-dose softgel.
- Routine fit. Drops go in coffee, water, or straight — buyers describe it as the supplement they actually remember to take.
The counterweight, also from buyer reports: taste. On the unflavored version, reviews are mostly neutral — “goes down easy” is the pattern. On flavored versions, expectations vary; more than one buyer says the flavor tastes more like the vitamins than the fruit on the label. If taste is your deciding factor, unflavored is the safer first bottle.
What Buyers Report: The Pattern Across 14,000+ Ratings
- Category standing. Top-10 placement in Vitamin D3 & K2 Combinations, with a best-sellers rank around the top 1,600 in Health & Household — this is a high-volume listing, not a fly-by-night label.
- Value math buyers do: two bottles per order, roughly 60 days of servings at the labeled dose, is the comparison shoppers run against single-bottle brands.
- Repeat buying. Subscribe & Save shows up throughout the reviews — buyers treating it as a standing winter-through-summer routine item.
And the standard cautions that apply to this whole category: D3 dose needs vary a lot person to person, K2 is a standard flag for people on blood thinners, and a 4.5-star supplement is still a supplement. The label is a starting point, not a diagnosis.
Who This Is For
- Adults whose doctor has already raised vitamin D and who’d rather take drops than another pill.
- People comparing D3-only products who want the D3+K2 combination in one bottle.
- Buyers who want an organic, no-filler label and a US-made product.
Who should skip it: anybody looking for a product to treat a condition — that’s not what supplements are for, and it’s not what this article is selling.
Bottom Line
NUSAVA’s D3 K2 drops are a mainstream, heavily reviewed option in a crowded category: clear label, organic certification, both K2 forms, and a liquid format that removes the pill problem. Start with the unflavored 2-pack, confirm the dose with your own clinician, and judge it the way buyers do — by whether it fits your routine well enough that you keep taking it.
