>Virtually no vitamins or supplements have actually been shown to have any benefit in proper randomised trials in normal people without severe deficiencies. Does this mean vitamin/mineral/iron supplements work for covering vitamin deficiencies ? So say I want to start a basic diet where I just eat whey + oat + seed/nuts to easily control my macros and have an easy to prepare diet - is there evidence that I will not have deficiencies if I take a "daily formula" supplement ? I've done this on my previous job for 6 months - it worked great for losing weight/gaining strength - I never felt weak, exercise recovery was as fast if not faster than when I was previously working out with a normal protein heavy diet (only downside was digestion adjusting for the firs two weeks - after that had 0 problems). When I changed jobs I lost my routine and stopped working out - been a hectic year. I'm thinking of start this again and staying on it - I'm wondering if there's any research if vitamin supplements work for people with deficiencies.
