It is easy to get overwhelmed by all the marketing but you should always start with the basics. A good multivitamin, some Omega-3, and maybe a protein supplement are the foundation. I personally use the Nutrilite range from Amway because they make it easy to understand what does what. You can see their full health catalog here https://www.amway.mn/buh-eruul-mendijn-buteegdehuun/c/bad-amway to get some ideas. I started with just the Daily vitamin and noticed my skin and hair looked much better too. You don’t need a massive stack of pills if you choose high-quality concentrates. Just be consistent and don’t expect results overnight.
