Capsules vs. Powders: Which gives you better absorption and results?

Great topic, Steve! I'm a huge fan of capsules for certain things. I've been using enteric-coated capsules for probiotics and some nootropics to ensure they survive stomach acid and get to where they need to be. For me, capsules have given more consistent results with things like ashwagandha—I feel less variation day-to-day compared to when I was mixing powders. But for pre-workout, I still stick with powders for that quick hit. Anyone else notice this split?

Thanks, Dan! That's interesting about the enteric coating—I hadn't considered that for absorption. I did a little experiment last month: I switched my magnesium from powder to capsules (glycinate form) and tracked my sleep with my Oura ring. Honestly, the capsules seemed to work just as well, maybe even a bit better for reducing nighttime wake-ups. But I'm skeptical if it's just placebo. Has anyone done any blind tests or have hard data on this? Also, what about fillers in capsules—are they something to worry about?

Good point on fillers, Steve. I always check the label for things like magnesium stearate or silica—some people claim they can cause issues, but in my experience, as long as it's a reputable brand, it's fine. For data, I haven't done formal tests, but I've noticed with capsules of curcumin (with piperine), my inflammation markers on blood tests improved more than with the powder version. Could be the formulation, though. What about cost? Capsules can be pricier—do you think the convenience and potential absorption boost are worth it?

Cost is a big factor for me too. I've found that buying in bulk and capping my own supplements saves a ton, but it's time-consuming. For things I use daily, like vitamin D or zinc, I go with capsules for the ease. But for experimental stuff, I stick to powders to adjust doses easily. Anyone have tips on DIY capsuling or favorite brands that balance quality and price? Also, has anyone tried those new liquid-filled capsules—are they any better?
