What is happening. Sea buckthorn oil is itself a common omega-7 source, so combining with separate omega-7 can duplicate palmitoleic acid exposure.
Mechanism. Additive intake of palmitoleic-acid-rich oils.
Recommendation. Avoid duplicate omega-7 products unless intentionally targeting a higher total dose.
