What to know
Traditional source of omega-3 with naturally high vitamin A and D. The catch: stacking it with a multivitamin can push fat-soluble vitamin A toward its toxic ceiling.
Interactions & cautions
- Vitamin A can accumulate — don't combine with other high-A products.
- High vitamin A is a concern in pregnancy.
Do you actually need it?
Good omega-3 source, but mind the vitamin A overlap.
