Hype Score
0 = legit, 10 = all hype
"It's a throat spray containing five medicinal mushroom extracts (Reishi, Chaga, Turkey Tail, Agarikon, Birch Polypore) grown on brown rice, with no disclosed doses of active compounds."
Consumer advice
- • If you want immune support from mushrooms, consider:.
- • buying individual mushroom capsules (Turkey Tail, Reishi) at higher doses proven in studies (1-3g/day), which will cost less;.
- • asking Host Defense to disclose the mg of active compounds (beta-glucans, triterpenes) per spray;.
- • understanding that spray delivery is less studied than capsule form, so efficacy may be lower. If you like the convenience and brand, the price is fair, but don't expect dramatic immune benefits—this is a modest supplement, not a cure-all.".
