Improving supplement absorption

1 day ago (edited)

What do you pay attention to when it comes to improving the absorption of supplements?

Any hacks or habits you’ve found helpful?


For example, combining fat-soluble supplements with the right foods?

I’m specifically interested in vitamin D.

I’ve seen the combo with K2 mentioned often, but what else matters?

  • Best time to take it?

  • Empty stomach or with food?

  • Fat source needed?

  • Any other factors that improve uptake?

Hi,

my approach would be to measure my levels and supplement based on that. If the specific metrics are not in the ideal range I'd change my strategy.

Everything else, in my opinion, is guess-work since actual absorption is very hard to measure. As long as the relevant markers are where I want them to be I am happy :)

There are, however, certain combinations that are well established like iron + vitamin C or D3 + K2, or not combining a certain nutrient with others, esp. Zinc or Coffee (polyphenoles) with Calcium or Iron. Since zinc and iron is something to keep in check as a vegan/pescetarian, I adhere to that.

For convenience I take (the few) supplements on my list right before breakfast on an empty stomach - except zinc (which I rarely supplement, though). Most of my meals contain a relevant amount of fat (~30-35%), so fat-solubility is taken care of.

Other than that: Building a resilient and well-functioning digestive tract I'd consider the most important aspect. That would mean fibre, pre- and probiotics, high plant diversity, low inflammatory foods.

Jep. Fat soluble supplements with meals, water soluble supplements with water between meels. I also try to avoid absorption competition (e.g. no Selenium with Vitamin C). And I take "uppers" (like B-Vitamins and L-Tyrosin for dopamin etc.) as early as possible and "downers" (for regeneration and relaxation) as late as possible.

It's a deep rabbit hole an I ended in having eight (in numbers: 8!) daily intake times ... For sure a bit too complicated in the long run (and I will hopefully get back to 5 soon) but the other solution would have been to increase the doses to get rid if my deficits ...
