@woodlittle I look for ones with methyl-forms of B vitamins (folate, B12, etc), because they are most available for your body.
I take Rue, the women’s multi is capsules but they’re minty, so you don’t have nasty vitamin burps lol
As far as fish oil, I just eat but loads of salmon, sardines, mackerel, just lots of good, fatty, small fish (small fish are lower in mercury).
I forget which brand it is, but part of their marketing was that the vitamin was specific to fill in common gaps in nutrition based on normal diets, such as not including vitamin C because it’s so easy to eat high Vitamin C foods, so you don’t get “nutrient overflow”. Which seems smart.
Iron is also good, I would suggest desiccated liver tablets because it’s going to be better absorption and avoiding constipation like iron supplements.
Basically, focus on the high content foods of whatever nutrients your blood work shows you need, because that’s way more effective than any pill!!
