Overview
Someone who cannot absorb or swallow capsules well is the buyer this Superior Source tablet describes. It dissolves under the tongue and the listing ties it to immune, brain and nervous system support.
The sublingual format and bariatric friendly note are the reasons to consider it, with a stated strength. The limits are lactose in the formula and a missing serving size.
Who it's for
People who have had weight-loss surgery, or who struggle with swallowing pills, are the main match. Lactose-sensitive shoppers and those wanting a gentler dose should look elsewhere.
Pros and cons
- Sublingual, no swallowing
- Strength stated in the listing
- Bariatric friendly note
- Gluten free listing
- Serving size not listed
- High strength not suited to everyone
Performance notes
The tablet dissolves under the tongue so the vitamin is absorbed through the mouth lining rather than the stomach. That is why it is marketed to people with absorption concerns. Gum arabic and lactose are the other listed ingredients.
