NOW Supplements Vitamin D-3 2,000 IU, 240 Softgels

What the label shows

We read the Supplement Facts panel on NOW Foods' own product page and the identical panel text on the Amazon listing for the 240-count bottle (ASIN B001UZPY1O) on September 30, 2026 [1]. The two agree to the word. Reference intakes and the upper limit below come from the NIH Office of Dietary Supplements vitamin D fact sheet [2]; the Daily Value is the FDA's [3].

Directions are one softgel daily with a meal. The caution reads "for adults only" and asks you to consult a physician if pregnant, nursing, taking medication or managing a medical condition. The bottle prints a Non-GMO statement, a Kosher symbol (Triangle K, with a "contains gelatin" note), a Halal mark and NOW's "GMP Quality Assured" roundel; NOW's site names the last as an "Intertek GMP Supplement Certification" for its manufacturing [1]. None of these is a strength-verification seal such as USP Verified or NSF Contents Certified, and no such seal appears on this label; we did not check a certifier directory because there is no certifier claim to check. The bottle's "Bone & Immune Health*", "Supports Healthy Teeth*" and "Promotes Muscle Health*" lines, and the "Structural Support*" wording in the Amazon listing title, are structure/function claims: under US law the manufacturer must hold its own substantiation and notify the FDA within 30 days of using the wording, but the FDA does not review or approve the claim in advance [4]. They are NOW's statements, not findings of this report.

What the evidence shows

D3 versus D2. This is the D3 form. The NIH summarizes most evidence as showing that D3 raises blood 25-hydroxyvitamin D levels to a greater extent, and keeps them up longer, than D2, although both are absorbed well [2]. A 2012 meta-analysis found the same overall, with one honest caveat: the advantage was significant for large, infrequent doses but was lost with daily dosing like this softgel's [5]. For a once-a-day routine, then, D3 is a reasonable but not dramatic preference.

What "enough" means. The National Academies consider a blood level of 50 nmol/L (20 ng/mL) or more sufficient for most people, and the NIH lists older adults among the groups more likely to fall short, partly because the skin makes less vitamin D with age and partly because of more time indoors [2]. A blood test, not a guess, tells you where you stand; on its own, 2,000 IU a day sits comfortably inside the upper limit.

What a large trial found. VITAL randomized 25,871 US adults (men 50 and older, women 55 and older) to exactly this dose, 2,000 IU of D3 daily, or placebo for a median of 5.3 years. Vitamin D did not lower the rate of either of the trial's two primary endpoints, and the investigators reported no excess of high blood calcium or other adverse events at this dose [6]. Read both halves: no broad protective effect was shown in a mostly well-nourished population, and 2,000 IU a day for five years was not harmful in that population either.

Bone evidence is mixed. The NIH describes one meta-analysis of vitamin D alone (400–800 IU a day) that found no protection from fractures in 34,243 older adults, and another of vitamin D with calcium that found a 6% lower risk of any fracture and 16% lower risk of hip fracture in 49,282 older adults over about six years [2]. Bone wording on a vitamin D label is closest to the second kind of study, which paired vitamin D with calcium; whether any of it applies to you depends on your calcium intake and your starting level.

Take it with food. Vitamin D is fat soluble; the NIH notes that fat in the gut improves absorption, though some is absorbed even without it [2]. The softgel's olive-oil carrier helps, and "with a meal" on the label is the right instruction.

Adding up the sources. This is the part most labels skip. A 50+ multivitamin such as the Alive! Ultra tablets in Report R-01 already carries 50 mcg (2,000 IU). One cup of fortified 2% milk adds about 2.9 mcg (120 IU), a serving of fortified cereal about 2 mcg (80 IU), three ounces of sockeye salmon about 14 mcg (570 IU) [2]. Multivitamin plus this softgel is 100 mcg, the upper limit, before any of that. The NIH is blunt that vitamin D toxicity is almost always the result of supplements, and that the harm runs through high blood calcium: nausea, weakness, excessive thirst, and kidney stones among its consequences [2].

Calcium and kidney stones. In the Women's Health Initiative, 36,282 women past menopause who took 1,000 mg of calcium with 400 IU of vitamin D daily had a 17% higher rate of kidney stones over seven years than placebo; the NIH attributes the finding to the combination of high total calcium (about 2,100 mg a day from food and supplements) with vitamin D, and notes that shorter trials found raised blood and urine calcium but not stones [2] [7]. The practical reading: vitamin D plus a calcium supplement plus a dairy-rich diet is a combination to put in front of a clinician, especially if you have ever passed a stone.

Medicines. The NIH lists four interactions worth knowing: orlistat reduces vitamin D absorption; statins may lower the body's own vitamin D production, and high vitamin D intakes may in turn reduce the effect of atorvastatin, lovastatin and simvastatin; corticosteroids such as prednisone impair calcium absorption and vitamin D metabolism; and thiazide diuretics reduce calcium loss in urine, so pairing them with vitamin D can raise blood calcium, particularly in older adults [2].

Who it may suit, and who should look elsewhere

It may suit adults past fifty who spend most days indoors or live where winter sun is weak, who take no multivitamin, and whose clinician has measured a level and suggested roughly 2,000 IU a day. It is inexpensive, a single nutrient, and a small softgel. Consider looking elsewhere, or asking first, if any of these apply:

• You already take a multivitamin with 25 mcg (1,000 IU) or more of vitamin D: you may not need a second source, or you may need a smaller one such as NOW's 1,000 IU softgel.
• You take a calcium supplement, have high blood calcium, or have had a kidney stone: the combination is the concern, so ask a clinician before adding vitamin D [7].
• You take a thiazide diuretic, a statin, a steroid or orlistat: a pharmacist can tell you whether the pairing matters for your dose [2].
• You follow a vegetarian routine: the shell is bovine gelatin.
• You are pregnant or nursing, or take any prescription medicine: the label says ask a physician, and so do we.

Price, size and where it is sold

On September 30, 2026 the 240-softgel bottle (ASIN B001UZPY1O) was $8.83 on Amazon.com, or about 3.7 cents per softgel, listed as in stock and shipped and sold by Amazon.com. At one softgel a day that is roughly eight months of supply. The 120-softgel bottle (ASIN B0019LVGPC) was $5.18, about 4.3 cents per softgel, also in stock from Amazon.com, so the larger bottle is the better buy per dose if you will use it before the expiry date. Both listings were marked non-returnable for food-safety reasons, so Amazon's general 30-day return window does not apply; our returns page explains what that means. NOW's own site lists the same softgel in 30, 120, 180 and 240 counts, which we cite as a label source only, not as a place to buy [1]. Prices change; the figures above are observations on the date given.
