Sisu Sisu - Kid's Vitamin D 1000IU, 90 tab
Sisu Kids Vitamin D3 - 1000 IU - Supports the absorption of enough calcium to build strong bones and muscles. Adequate Vitamin D in children’s diets may also protect against a range of diseases, including multiple sclerosis and type 1 diabetes. Vitamin D is essential for a range of bodily functions. In particular, it activates the absorption of calcium, which is crucial for building bones and muscles. This is especially important in the growing years, as peak bone mass is usually achieved by the age of 25. If optimal bone mass is not achieved in these crucial years, osteoporosis and other bone diseases are more likely later in life. Vitamin D is also necessary to enable absorption of Vitamin C, and is required for good nervous system function and blood clotting. Chewable strawberry-banana flavoured tablets.

Why people keep reordering it
Best suited to: canadian kids from october to april, a child who will not swallow capsules, kids with darker skin.
What the research supports
One chewable tablet gives 1000 IU of vitamin D3, the form the body makes from sunlight. Ages 3 to 18 take one a day.
Studies use 400 to 1000 IU a day in children.
- Bone development (evidence: strong, from randomized controlled trial, observational study)
- Vitamin D controls how much calcium the gut absorbs from food. Getting enough through the growing years tracks with stronger bone mineral accrual.
- Winter vitamin D (evidence: strong, from randomized controlled trial, observational study)
- Skin makes vitamin D from sunlight, and Canadian daylight is too weak to do that from October through April. Daily doses of 400 to 1000 IU keep it topped up through those months.
- Immunity (evidence: moderate, from randomized controlled trial, meta-analysis)
- Pooled trials of daily vitamin D find a modest drop in respiratory infections, but mainly in people who started out low. Someone already replete won't notice much difference.

Is it right for you
Worth it if
- Canadian kids from October to April
- skin makes effectively no vitamin D at Canadian latitudes over the winter half of the year, and 1000 IU covers that shortfall with margin.
- a child who will not swallow capsules
- a chewed tablet needs no water, no dropper and no splitting, which is usually the difference between a daily habit and a forgotten bottle.
- kids with darker skin
- more melanin means slower vitamin D synthesis from the same sun exposure, so the dietary route carries more of the load year-round.
Look elsewhere if
- infants and toddlers under three
- the directions start at three years and a hard tablet is a choking risk before then. Use a liquid D3 drop dosed at 400 IU.
- families avoiding all added sugar
- the tablet base is compressible sugar and fructose alongside xylitol. A plain D3 drop in oil has no sweetener at all and absorbs at least as well.
- a teen who prefers weekly dosing
- this is a daily 1000 IU tablet. If a once-weekly routine is more realistic, a higher-strength softgel taken weekly reaches a similar total intake.
What to expect
Nothing perceptible, ever. Vitamin D produces no sensation, and its job here is holding blood levels steady through a Canadian winter rather than changing anything day to day. Blood 25-hydroxyvitamin D takes roughly 8 to 12 weeks of daily dosing to settle at a new level, so a test before and after should be spaced at least that far apart.
How it compares
- Compared with a vitamin D3 drop in oil
- no measuring and no dropper, and a strawberry-banana chew is far harder for a child to refuse than oil off a spoon. The tradeoff: the tablet needs sugar, fructose and flavour to work as a chew, and the oil drop carries its own fat, which is exactly what D3 needs for absorption.
- Compared with the vitamin D already in a kids multivitamin
- 1000 IU of D3 against the 200 to 400 IU a chewable multi typically carries, and in the form that holds blood levels rather than the D2 many of them use. The tradeoff: it does one thing only. No vitamin C, no B complex, no zinc, so it is an addition rather than a swap.
