Earth Wise Vitamins & Supplements UBIOSKA Vitamin D3 + K2 + Mg 4000IU 3-in-1 Formula Review

All three ingredients are at or near the doses used in studies. Vitamin D, here at 4000 units a day (above the usual daily limit, so members can take less), modestly lowered fasting blood sugar, the long-term blood sugar marker and insulin resistance in people with type 2 diabetes in two large pooled analyses, most in people low in vitamin D ^[1][2]. In prediabetes it cut the risk of developing diabetes by 15% ^[3]. However, a trial of 22,220 older adults found no significant drop in diabetes risk ^[4], and another pooled analysis found no change in fasting blood sugar in prediabetes ^[5]. Vitamin K2 ranked well for lowering long-term blood sugar in people with type 2 diabetes ^[6]. Ninety micrograms daily lowered the long-term blood sugar marker and insulin resistance over six months ^[7], though one review found lower insulin resistance but no change in blood sugar ^[8]. Magnesium lowered fasting blood sugar in people with diabetes and improved insulin sensitivity in people at high risk ^[9], and 250 milligrams of magnesium oxide helped women with polycystic ovary syndrome ^[10]. Some trials found no change ^[11][12]. Animal and cell studies are never counted.

Vitamin D3, magnesium and vitamin K2 are all treated as main ingredients here, and the panel is broadly positive on each. Most of the panel recommends or uses magnesium, mainly for sleep, with glycinate and threonate the preferred forms; doses given were 400 mg of threonate before bed by two of them, and around 300 to 400 mg a day from diet and supplements by one. For vitamin D3, three of them take 5,000 IU in the morning or list it as a staple, and several say to take it with dietary fat, aim for a healthy blood level, and pair it with magnesium, which one says helps the body activate it. Vitamin K2 came up from three of them, who describe it as steering calcium to bones and away from arteries, with one taking 90 mcg in the morning and another pairing it with D3 and morning fats. The cautions were that one said vitamin D is not worth taking for most things unless you are deficient, and one said magnesium does not fix waking in the night; no one said they stopped.
