NatureWise supplements: vitamin D3, D3 with K2, probiotics

NatureWise is an American supplement brand best known for one small decision: it dissolves fat-soluble vitamins in a real food oil. The vitamin D3 softgels use organic extra virgin olive oil. The D3 with K2 softgels use organic cold-pressed coconut oil, which also means they contain a tree nut. Vitamin D needs fat to be absorbed, so the carrier is not decoration.

The catalogue is narrower than that of many brands in our range, and that helps you choose. You will mainly find vitamin D in several strengths, D3 paired with vitamin K2 as MK-7, a vegan D3 made from lichen, a multi-strain probiotic with prebiotic fibre, CLA from safflower oil and organic turmeric curcumin. Simple formulas, readable labels, everyday prices.

Strengths and what they mean in the UK

The vitamin D3 softgels run from 1,000 IU up to 5,000 IU per serving. UK guidance is 10 mcg (400 IU) a day for most people, with 100 mcg (4,000 IU) as the daily upper limit for adults. That makes the 1,000 IU and 2,000 IU versions the sensible everyday picks. The 5,000 IU softgel sits above that upper limit, so treat it as something to agree with your GP, not a default choice. Vitamin D contributes to the normal function of the immune system and to the maintenance of normal bones.

Two other choices matter. The vegan D3 uses lichen instead of lanolin from sheep's wool, which is the usual raw material for D3. The probiotic uses a delayed-release capsule, so more bacteria survive stomach acid, and adds organic inulin as prebiotic fibre. If you already take a probiotic with live cultures, compare strains and release type rather than headline bacteria counts.

Why we stock NatureWise

We judge a brand on three things: the form of the ingredient, the dosage, and whether the combinations make sense. NatureWise does well on the first two. D3 in olive oil is a form that absorbs, and the strengths are spread widely enough that you can pick a suitable dose instead of the loudest one. We stay honest about the rest: the 5,000 IU option is above UK self-care advice, and CLA supports a routine rather than replacing one. Every product passes our compliance team before it goes live, and we test batches ourselves next to independent labs. See how we choose our brands.

Who these supplements suit

Year-round vitamin D users: small softgels, several strengths, large counts that last months.
Vegans: the lichen-based D3 and the CLA from safflower oil, not the standard lanolin softgels.
People who dislike big capsules: the mini softgels are among the smaller ones we carry.

One honest expectation. Nutrients like vitamin D work by keeping your intake steady, not by giving a noticeable lift on day one. Give any new supplement two to three weeks of consistent use before you judge it, and keep going through autumn and winter, when UK daylight is too weak for your skin to make vitamin D. Store softgels somewhere cool: they can stick together in a warm cupboard.

NatureWise is an American brand with a fairly compact range. The core is vitamin D: plain vitamin D3 softgels in several strengths, a D3 with K2 combination using menaquinone-7, and a vegan D3 made from lichen. Around that sit a multi-strain probiotic with prebiotic fibre, CLA from safflower oil, organic turmeric curcumin and a small number of vitamins and minerals. Formulas are single-purpose rather than long ingredient lists, which makes them easy to combine with what you already take.

Yes, through retailers. NatureWise closed its own European and UK sales operation in 2018, so the brand no longer ships directly to UK addresses. That is why you mostly see it through shops rather than on its own site. We buy directly from the brand, without intermediaries, so what you receive is authentic stock with the same labelling and batch traceability. Every batch passes our compliance check before the product goes live in our shop.

Only some of them. The standard vitamin D3 softgels use cholecalciferol from lanolin, which comes from sheep's wool, so they are not vegan. The Vegan Vitamin D3 uses lichen instead and comes in a plant-based softgel, and the CLA is made from safflower oil. Always check the label of the specific bottle, since gelatine in the shell is the usual sticking point. You can also browse our wider vegan supplement selection if you want plant-based options across brands.

Vitamin D and vitamin K are fat-soluble, meaning your body absorbs them together with fat. A dry tablet taken on an empty stomach gives your gut less to work with. Dissolving the vitamin in oil inside the softgel supplies that fat with every dose. NatureWise uses organic extra virgin olive oil for its D3 and organic cold-pressed coconut oil for the D3 with K2. It is a small detail, but it removes the need to time your dose around a fatty meal.

Be realistic. Vitamin D builds up in your body slowly, so a bottle is about keeping your intake steady rather than producing a same-day effect. Most people should judge a new routine after two to three weeks of daily use, and vitamin D levels in blood typically shift over a couple of months. Probiotics work differently: gut effects, if they come, usually show within one to four weeks. CLA supports an existing training and eating routine and does not replace one.

NSF is an independent testing organisation. When a supplement carries its certification, the contents have been checked against the label for accuracy and screened for harmful levels of contaminants. NatureWise applies this to specific items, including several vitamin D3 strengths and the vegan version, not to the entire range. So check the individual product rather than assuming the whole brand is covered. We add our own layer on top: we test products ourselves and independent labs spot-check batches.
