Key Ideas

Multivitamins

Several scientific reviews have shown daily multivitamins to have a weak effect on preventing heart attacks and improving cognition. Instead of taking one pill that can't possibly fit every person's daily requirements, it’s recommended to supplement specific deficiencies or needs.

If you're worried about a particular health problem, pay no attention to your diet, or are always dieting, then search for the common vitamin weakness, and look at your diet.

Vitamin D

Essential for bone and mineral metabolism, it has been found to affect other systems, including the cardiovascular, muscular, endocrine and nervous. But only for those with genuine deficiency, vitamin D supplementation have significant benefits.

A blood test will show your vitamin D levels, and from there you can make an informed decision. 

Glucosamine

Joint pain and osteoarthritis are commonly treated with glucosamine, and it helps with pain relief and slowing down arthritis.

Be sure you are using glucosamine sulfate, as glucosamine hydrochloride has been shown to be less effective. 

Protein Powder

Whey protein has been shown to help aging men increase or preserve muscle mass, which is very important for mobility and overall health. To find out if you should use it, work out whether or not you are not eating enough regular protein.

There is no "best diet"

The “best” diet is a theme: an emphasis on vegetables, fruits, whole grains, beans, lentils, nuts, seeds, and plain water for thirst. 

That can be with or without seafood; with or without dairy; with or without eggs; with or without some meat; high or low in total fat.

The "Age" of vegetables
The best vegetables are likely to be fresh and locally sourced, but flash frozen is nearly as good (as freezing delays aging). Those “fresh” vegetables that spend a long time in storage or transit are probably the least nutritious.

Research Findings On Supplements
  • Pharmaceuticals undergo extensive testing to prove they're effective and safe before they can be sold, but dietary supplements can be sold without proof of claims, effectiveness or safety.
Supplements And Doctor Prescriptions

Because of the potential risks and unclear benefits of supplements, most doctors advise against them. However, doctors often recommend specific vitamin and mineral supplements to their patients, such as calcium and vitamin D to prevent osteoporosis and iron for people with iron deficiency.

When Buying Supplements
  • Consider only single-ingredient supplements. Multi-ingredient supplements make it hard to identify which substance is having an effect and they are more likely to be adulterated with banned drugs.
  • Tell your doctor about any supplement you take, so they can check it will interact with any of the medicines you're on.
