My son has this too. I’ve read omega’s may help. Here’s snippet:
Other medications that have shown promise in postinfectious OD include intranasal sodium citrate, which is thought to modulate olfactory receptor transduction cascades, intranasal vitamin A, which may act to promote olfactory neurogenesis, and systemic omega-3, which may act through neuroregenerative or anti-inflammatory means.9,10 The latter 2 medications may serve as adjuvant therapies in olfactory training. However, to date, there is no evidence that these therapies are effective in patients with OD related to COVID-19.
