What do you personally look for to trust a supplement long term?

There’s no shortage of supplements promising focus, energy, or longevity — but trust seems to be the real bottleneck.

Some people care most about:

• Ingredient transparency
• Clinical research
• How their body feels over time
• Brand philosophy
• Third-party testing

Others rely more on personal experience than data.

I’m curious how people here think about it.

What factors actually make you trust a supplement enough to take it consistently over months or years?
