"Proprietary blend with no disclosed per-ingredient doses"
Impossible to verify if mushroom, enzyme, or vitamin doses are clinically effective. Proprietary blends typically underdose expensive actives.
Internal: proprietary blend analysis -
"Mushroom blend supports immune function"
Mushroom studies are small (n<100) and short-term. No clinical evidence this blend prevents seasonal illness.
PubMed: Mushroom Blend (KNOWN - in knowledge base) -
"Digestive enzyme blend supports digestion"
One small RCT (n=120) showed benefit for functional dyspepsia. Healthy adults with normal digestion see minimal benefit.
PubMed: Digestive Enzyme Blend (KNOWN - in knowledge base) -
"Food-based ingredients for enhanced bioavailability"
No clinical evidence fruit/vegetable extracts improve absorption of other ingredients in this formula.
Consumer advice
Before buying, request the full ingredient label with per-ingredient doses from the manufacturer. If they refuse or cite 'proprietary formula,' that's a red flag—it usually means underdosing. For immune support, you'd get better value buying a standalone vitamin D3 (5,000 IU, ~$8-12), a quality probiotic (~$15-20), and a basic multivitamin (~$10-15) separately, which would cost less and let you verify actual doses. If you do buy this, don't expect dramatic immune benefits—the hedged language ('support,' 'help') is appropriate because clinical evidence for this specific blend is absent."
