If you have joint pains then stick it out. It has given my mum a bit of a lifeline with her dodgy hips.
I take Centrum multi-vit just as a top-up as it was the only one I could find that didn't have bonkers NRV values (the worst is 143% for Vit B6) and I take Magnesium at night to help sleep.
Coffee, chocolate and monster much usually sorts me out.
None, if your diet is good then all the intake vitamins you need will be contained in the meals/fruits you eat anyway so don't need excess vitamins. Anything else will be down to as mentioned above ^
But since it's difficult for people to get enough vitamin D from food alone, everyone (including pregnant and breastfeeding women) should consider taking a daily supplement containing 10 micrograms of vitamin D during the autumn and winter.
This is not true, it is recommended that everyone take vitamin D in the winter because it isn't found in the typical diet.
