Hi there
i agree with steven.
With our current lifestyles, food quality, and most importantly our dietary food choices , the need for a quality multi ingredient supplement is clear.
Most people eat terrible diets and are nutrient deficient (and don't know it because they have marginal deficiencies). But 40 - 60 years of nutritional self abuse will eventually catch up with them. Thats why the rates of all degenerative disease are sky-rocketing.
Even the ultra conservative american medical association who for the last 40 years denied the necessity of supplementation (in the face of substantial scientific evidence!) has now recommended in their journal (jama) that we take a daily supplement.
The nutrient levels in some food has certainly decreased - here's one example
'amounts of vitamin c in 100 g of spinach'
1950 = 150 mg
1963 = 100 mg
1982 = 063 mg
1994 = 013 mg
but too much is made of nutrient deficient soil. California, washington, oregon, texas, florida and many other states still have very rich, fertile soil. America provides some of the most nutrient-rich produce in the world.
Americans are not nutrient deficient because of depleted soil - it is because they do not eat a sufficient amount of fresh produce. Over 90 percent of the calories consumed by americans come from refined foods or animal products.
Good nutrition information is everywhere and easily accessible but people dont want to change. They prefer to eat nutrient deficient food because it tastes great - rather than eating for health.
So not only do we need a supplement containing vitamins and minerals (to top up what we're deficient in) but we also need other ingredients in our supplement to counter all the health problems created by our poor food choices.
Specifically lots of high potency phytonutrients, herbal extracts, as well as amino acids, enzymes and male and female support nutrients to tackle common health concerns of each sex (e.G. Prostate problems in men and menstrual problems in women etc etc).
The best vitamin supplements must have some of everything (but not in huge doses like you see in many vitamin/mineral formulations). By including some of everything that's as close to a customized supplement as nutritional science currently allows.
To set the record straight grains and animal feed crops grown in the southeastern states are the most deficient, but even in these states only a small percentage of crops are shown to be deficient in minerals.
