How you can tell whether you're absorbing the nutrients in your foods

Is an ingredient added to your supplements preventing you from absorbing the magnesium from your foods or mineral supplements? What about other ingredients that you may have overlooked and how taking daily doses might affect your body such as possibly preventing you from absorbing the nutrients from your foods or other supplements?

What do you need to ask about your supplements? When you read the many reviews of various supplements or foods, how do you validate whether the positive reviews are backed up by scientific research, whether people are giving feedback based on real changes in absorption levels or health, whether the review might reflect a placebo effect, or whether actual scientific studies were done on the chemical, food, or supplement?

With all the health food stores, what should you look for in a vitamin or mineral supplement that might prevent you from even absorbing the vitamin in the first place or other minerals such as magnesium from your foods?

Do you follow what the reviewers said about a product and buy it immediately?  How do you separate marketing and promotion from scientific studies that are not flawed or reviews from the results of actual tests?

Do you look for validated evidence? And do you wonder whether your body will respond to the supplement in a similar way, since your genetic signature and expression is probably different from the person who posted a personal experience with any given product?

First find out how deficient you are in minerals. If you're being tested, is the test looking at the minerals in your cells, in your blood serum, or just in a simple blood test? You want to find out whether you're absorbing minerals and which ones at normal quantities.

Next, you want to find out whether the supermarket variety of supplements you may have bought have any type of deficiency in minerals. Questions you might ask a manufacturer of supplements are: Is the product bioavailable? What's in it to prevent it from being absorbed? To test your vitamins or other supplements, see whether they dissolve in a glass of water before 15 minutes have passed. Do this with a multivitamin tablet.

If the supplements do not dissolve in water within that 15 to 20 minute time frame, the supplement probably won't dissolve in your body and be eliminated without being absorbed where you want it to go. What makes tablets or even some types of capsules unable to dissolve is the fillers used to make the tablet or other shape hard. But the fillers, themselves, interfere with your body's ability to absorb not only the supplement, but also any magnesium you take from food or other supplements.

You could develop too low a level of magnesium. So you need to talk with a health professional to find out whether your body is absorbing magnesium from food or other supplements to prevent a magnesium deficiency over time. Some calcium fillers such as tricalcium phosphate added to vitamin tablets or other supplements to harden them could prevent magnesium from being absorbed by your body from other sources. So check with a professional, be tested for magnesium levels, and make sure your body can absorb magnesium from foods or other supplements.

Some people are taking various brands of lecithin daily. And some containers of lecithin granules say on the label that tricalcium phosphate is one of the ingredients. So check out your foods and supplements. Also, some people add lecithin and pureed prunes to baked goods to substitute for added oils or fats. Be aware of what you're eating daily.

The big problem with calcium is that sometimes it prevents magnesium absorption. That's why you'd take magnesium calcium supplements at different times of the day, rather than swallow a pill that has magnesium and calcium together in the same tablet. Check it out. Magnesium and calcium are both antagonistic to each other.

When you look at the writings of some naturopaths and others following natural treatments, one of the first tests they take is their urinary PH levels. Some nutritionists and naturopaths may see whether someone's urinary pH is not 6.5. Now, the question is whether your body can or cannot absorb nutrients, supplements, minerals, or any thing good that comes from food if your urinary PH is not normal. The question is first, whether pH 6.5 is the optimum pH to have in order for the body to absorb minerals from food or supplements.

You could test your urinary pH using baking soda (sodium bicarbonate) to increase alkalinity and using vitamin C in the form of ascorbic acid to increase acidity, according to some nutritionists and naturopaths and others interested in various types of folkloric and natural tests.

Or you can use  sodium ascorbate, which is another type of vitamin C to increase your pH alkalinity. But before you do all this testing, find out first from naturopaths or nutritionists if this health information about foods and supplements has any validity in actual scientific research.

Otherwise, it's evidence from people who have knowledge of supplements, but you have no way to check out their backgrounds as many of these types of posts online don't give the person's qualifications when they write about such testing and related health information. So for educational purposes, check out whether there have been scientific studies on these tests.

Many distributors of minerals and vitamins and their followers write about the use of humic acid/fulvic acid to maintain the health of the intestinal flora for making foods eaten more bioavailable. Do you take a fulvic acid supplement, and if so, is this practice healthy or not?

That's what you need to find out from research and health information that you can actually validate. Some nutritionists say fulvic acid will increase the absorption from your food of minerals. The idea is to achieve normal or optimum levels of absorption.

In the past, fulvic acid has been fed to plants. But are they safe for humans? Lots of people take the supplements for achieving mineral balance. The best way to look is to test your blood to see what changes are happening right away.

Some nutritionists look at chemicals such as sodium citrate which chelates calcium and magnesium. The goal you want is better mineral absorption. But before you take anything, find out what's pure, what scientific evidence validates the use of fulvic acid, and whether you can get fulvic acid just from foods such as chicken livers, blackstrap molasses, sea vegetables like a sheet of nori seaweed, or organic vegetables. You could do a search online with the question of "Which foods have the highest levels of absorbable fulvic acid?"
