So first, you look great!
Supplements. That's a tough question. And lots of opinions and equally amounts of false info out there, so do be careful.
I large part, I think I'd try to source as much of my nutrients and micros naturally -- given that so many of them work in concert with each other. Isolated into supplement form can impact both the bio-availability and efficiency of them. It takes a fair amount of reading, asking questions, and experimentation.
Easier said than done, eating a range of grains, nuts, colors of veg, fruits, and hoping to get the right portions is pretty easy for just general wellness. Trying to source the right balance of macros ontop of it to help with fitness/performance goals is like going to the next level.
My usual question, is what are you eating on a typical day? Foods and rough portions/frequency?
That will help!
I try to source my nutrients as directly as I can from foods. However, if you came over and looked in my pantry you'd find NOW Pea Protein Powder (great in smoothies, helps with protein macros when my daily intake is pretty light), hemp powder, ground flaxseeds, chia seeds, an awesome organic superfood smoothie mix (acai, goji, and other good stuff), great multi-vitamin (as I was 'low' on my Vit D and Bs), and a bio-available magnesium supplement. Full transparency, authenticity.
Currently training for 1/2 marathon while working out to maintain my strength/physique. So my food intake is kinda all over the place depending on whether I'm doing running training or weights. LOL. Some days feels like complete opposite objectives, but I digress...
