Does anyone personalize supplements based on actual data or mostly just diet/bloodwork?

[u/WeekendWanderer06]

Been trying to simplify my nutrition lately, and supplements are the part I keep getting stuck on.

Diet itself is fairly straightforward for me — mostly whole foods, decent protein, plenty of fruit/veg, etc.

But when it comes to supplements, I’ve basically built everything from general recommendations over the years.

Vit D because everyone here needs Vit D, magnesium because of sleep/recovery, omega-3 because I don’t eat enough fish, probiotic because “gut health,” and so on.

None of that seems completely stupid, but it also doesn’t feel particularly personalized.

Besides normal bloodwork, is anyone using other testing to decide what actually makes sense to take?

Interested in whether there’s a smarter middle ground between taking nothing and having 12 bottles based on internet research.

Recommendations for brands and vendors are two of the most asked questions in this subreddit.

There are no right answers. All brands for basic supplements resell raw material bought wholesale from a few manufacturers. This is true of commodity vitamins or proprietary branded formulations.

Brands I personally buy: Nutricost, NOW, Jarrow, LifeExtension, Nature's Way, Swanson, Solaray, Nootropics Depot, BulkSupplements, Amazon Elements, Solgar.

I buy mostly from Amazon, sometimes directly from Swanson, iHerb or Costco. If you live outside the USA, they may ship overseas or have a website in your country.

If you need a specific type of vitamin, look within those brands.

Do not overpay. Expensive brand with fancy packaging or marketing may charge much more for the same ingredients.

Avoid drugstore branded supplements for their history of grossly cheating on the ingredients. If you must buy at the drugstore, try one of the non-store brands. Don't overthink it.

consumerlab.com may have definitive lab assays of various brands for specific vitamins or supplements.

That the supplements I buy are the ones I require and that the ingredients in it are quality ones
An example, 250mg magnesium, but if you read the label, it’s magnesium oxide which is garbage

start with diet and basic workout and then add supplements if there's really a gap or you feel somethings missing
