I agree that there is a great deal you can do through supplementation - I can help you with that. DO NOT take individual supplements (vitamin this, mineral that) as they do not work in isolation. Don't take anything in pill form - waste of money, very poor absorption rate. (That's why there is so much medication and vitamins in the water supply - it's been in articles and news reports a lot over the past few years.)
Healthy diets are helpful but not sufficient. All reputable food scientists agree that there's just no way, since the nutrients just aren't in the food anymore. Even if you eat local/organic, you just can't take in enough nutrients because the soils are so depleted and even organic food that is shipped from across the country or halfway across the world was picked early, before it drew up a full supply of nutrients from the soil (which still can be depleted and the food considered organic).
Hormone replacement therapy may be suggested to you but it has side effects long term that may make you question that decision.
I've sailed through menopause with excellent supplementation because I got a lot of help from a company's trained advisors (free) and it's helped tremendously. I make it my mission to help other women.
You won't miss having periods, most likely - but you're right, it's the other stuff that is difficult.
More importantly, what's caused this premature failure? Something's not right with your body and you can help restore it to its fullest efficiency and highest condition.
