Hi there,
beware of the marketing spin concerning liquid vitamin products.
Manufacturers of many liquid vitamin supplements have been making some hefty claims in that their products have extremely high levels of bioavailability (absorption) – much higher than that of tablets.
In some cases they’re claiming bioavailability rates of almost 100% (e.G. Seasilver)!
Many of the companies selling liquid multi vitamins are multi level marketing companies – they rely more on hype and spin than good science to sell their products.
They take advantage of the fact that supplement consumers do not understand the principles behind the bioavailability of nutrients and so they structure their marketing presentations to make it appear that the bioavailability and efficacy of their product is much higher than it really is.
A major problem we need to think about is that a number of the most important key ingredients used in supplements (tablet or liquid) are susceptible to destruction by stomach acids.
Because of this there are many scientists that believe only about 10 - 15% of the active ingredients make it into the blood stream. (this is considered an approximate industry average by many scientists).
The only supplement delivery system that overcomes this problem is called enteric coating (applied to hard tablet supplements). This harmless aqueous coating protects the ingredients as they pass through the stomach until they reach the upper intestine where absorption takes place. Enteric coating has been used to protect key ingredients in pharmaceutical drugs for many years and is a main factor as to why drugs work so well.
Since liquid nutritional supplements have no delivery system how on earth do they claim near 100% absorption?
Their nutrients are susceptible to destruction by stomach acid just the same as non-enteric coated tablets. If however they do not contain any of these key ingredients then that's ok. (vitamins and minerals are not effected - but a highly efficacious and nutritionally complete multi ingredient supplement will contain far more than just vitamins and minerals).
'liquid life complete' which you asked about describes itself as a complete nutritional product - but the formula is very simple. Most of the key ingredients are missing . And it contains iron which it should not! Iron is an oxidant – too much iron oxidizes ldl cholesterol which makes it more toxic and more likely to end up in the arteries. Only people diagnosed with a deficiency should supplement with iron.
Liquid life costs only $20 because it is primarily made up of vitamins and minerals - the cheapest ingredients in supplements. 800 mg of vitamin c is too much (in doses of 400mg up, vitamin c acts as a proxidant - the opposite of antioxidant!) the dose amounts of the herbals and amino acids are really small - these are key ingredients and the health benefits from such small doses are questionable. Thats why it costs only $20.
Manufacturers of liquid nutritional supplements also usually make a big fuss that their products contain enzymes (liquid life doesn't). Don’t buy the hype with those that do!! The enzyme component is negligible because they are not added, but are naturally occurring within the food matrix used in liquid multi vitamins. There are only trace amounts – nowhere near enough to be of benefit.
Enzymes cannot be added into to liquid nutritional supplements due to their sensitivity. They can only survive in a liquid form for approximately a few hours.
To get maximum absorption (estimated at around 80%) you need a supplement in tablet form that is enteric coated.
I believe the leading liquid vitamin supplements are very pricey for what they offer- they don't give you good value for money (and check the labels for any artificial sweeteners to mask the bitter taste of vitamins - and for any preservatives). 'liquid life complete' is sweetened with crystalline fructose - this is ok (comes from cornstarch).
You may like to take a look at the enteric coated supplement I use- it costs about the same as the leading liquid supplements (and has 83 ingredients). You can see it evaluated and reviewed against the leading supplements in the industry (including lifepak which dave mentioned above in this thread)

and look for my page about bioavailabilty (absorption) of supplements - it gives the names of all the ingredients damaged by stomach acid.
Hope this helps
cheers
