Overview
Superior Source Vitamin D3 5000 IU comes as 100 sublingual dissolving tablets meant to dissolve under the tongue rather than be swallowed, aimed at calcium absorption, bone health and immune, brain and nervous system support, and marketed as bariatric friendly.
Sublingual tablets dissolve under the tongue instead of passing through the stomach, a delivery method Superior Source markets toward people whose digestion may limit absorption of swallowed pills, which is also why it is labeled bariatric friendly. At 5000 IU per tablet, this is a considerably higher potency than standard 1000 or 2000 IU vitamin D3 products, so it suits people targeting a higher daily dose rather than baseline maintenance. The tablet base lists lactose despite an unflavored profile.
