- 01ZincStrong92% match
Zinc is essential for the taste-bud enzyme gustin and for olfactory cell turnover, so correcting a deficiency can restore blunted or distorted taste and smell.
SuggestedZinc picolinate or zinc gluconate, 15 to 30 mg daily with food - 02Vitamin B12Moderate74% match
B12 deficiency can cause glossitis and altered taste through its effects on tongue mucosa and peripheral nerves, which can reverse with repletion.
SuggestedMethylcobalamin sublingual or oral - 03Vitamin ALimited66% match
Vitamin A supports epithelial and olfactory mucosa integrity, and deficiency has been linked to reduced smell perception.
SuggestedVitamin A (retinyl palmitate) at conservative doses, or beta-carotene - 04Alpha-Lipoic AcidLimited58% match
As an antioxidant with nerve-supportive effects, alpha-lipoic acid has been trialed for post-viral and idiopathic smell loss to aid sensory nerve recovery.
SuggestedAlpha-lipoic acid, 600 mg daily - 05Fish OilLimited50% match
Omega-3 fatty acids support olfactory neuron membranes and have shown signal for protecting or aiding recovery of smell after surgery or viral insult.
SuggestedHigh-EPA and DHA fish oil
