Minerals for nutritional supplements

Publish date: 2015-09-28

The human body normally gets adequate amounts of minerals and vitamins with food; however an additional intake of minerals through food supplements may become necessary for various reasons. Particularly an unbalanced diet which is poor in nutrients, various diseases or an increased demand in certain phases of life like pregnancy can lead to deficiency symptoms. Living in a deficiency area can provoke similar effects. A deficiency of iron, iodine or selenium is often caused by this. A regular intake of appropriate food supplements can prevent or compensate a mineral deficiency.

The use of vitamins and minerals in food supplements is regulated by directive (EC) No. 2002/46. For the fortification of food the Regulation (EC) No 1925/2006 has to be considered1, 2.


Calcium is found in the body mainly in form of calcium hydroxyapatite in teeth and bones. In addition to this calcium has an important function in the stimulation of nerves and muscles. A calcium deficiency can thus lead to muscle cramps. Numerous secretion processes are also only possible in the presence of calcium, e.g. insulin release from the β-cells in the pancreas7.

Natural sources of calcium are in particular milk products, but also various vegetables and drinking water contain adequate amounts of calcium. However, the calcium taken in with food has relatively low bioavailability of about 30 - 50 %.

A regular consumption of nutritional supplements containing calcium can thus facilitate achieving the current nutrient reference value (NRV) of 800 mg / day according to Regulation (EU) No 1169/20113. A daily dose at this level requires a realistic form of dosage. Dr. Paul Lohmann® has suitable compounds in the product range for application areas from tablets to liquid products. For the latter for example the product Calcium Lactate PLUS is very suitable. Especially the good bioavailable mineral L-pidolates including for example Calcium L-Pidolat and the Calcium Glycerophosphate are ideally suited for this application.


Magnesium occurs in plant tissues as a central atom of chlorophyll, therefor that all green vegetables are important sources of magnesium.

As an essential co-factor, magnesium is involved in multiplicity enzymatic reactions. According to the Regulation (EC) No 1924/2006 on nutrition and health claims made on foods magnesium contributes to a reduction of tiredness and fatigue and a normal energy-yielding metabolism. Furthermore it contributes to normal functioning of the nervous system and the muscle function and supports the maintenance of normal bones and teeth4.


Dr. Paul Lohmann® offers for food supplements magnesium salts like e.g. all Citrates, Carbonates, Gluconates, Lactates, Bisglycinates (metal chelates) and Aspartates.


More than 300 enzymatic reactions in the human body depend on the presence of zinc. Zinc has gained particular significance in recent years through its positive effects on the immune system. Due to the contribution to the normal function of the immune system10, OTC zinc compounds and zinc containing food supplements are frequently used in colds. Placebo-controlled studies have in fact shown that the intake of zinc significantly shortens the duration of illness5. Furthermore zinc is known as the beauty mineral because it contributes to the maintenance of normal hair, nails, and skin4.

The body’s storage capacity for zinc is relatively small so that a continuous intake through food or nutritional supplements is recommended. Dr. Paul Lohmann® offers a broad spectrum of zinc salts as e.g. Zinc Acetate, Zinc Bisglycinate, Zinc Citrate, Zinc Gluconate, Zinc Lactate, Zinc Oxide or Zinc Sulfate.


Iron is quantitatively the most significant trace element in the body. The amount of iron finally absorbed from a respective foodstuff is determined by its bioavailability. Iron from meat sources is readily available with its absorption rate of 10 - 20 %6. Iron in vegetable foodstuffs exists mainly in the Fe3+ form that cannot be absorbed. The availability of iron from vegetable food is thus with 1 - 5 % very low altogether.

The intake of nutritional supplements containing iron is recommended for vegetarians and vegans. But there is also an increased iron requirement during growth periods, in increased sports activities and during pregnancy. Dr. Paul Lohmann® offers a broad range of highly bioavailable iron salts e.g. Ferrous Sulfate, Ferrous Lactate, Ferrous Gluconate, Ferrous Fumarate or Ferrous Bisglycinate.

Dr. Paul Lohmann® – partner for innovative mineral supplements

Dr. Paul Lohmann`s portfolio of mineral salts for food supplements is available in various pharmaceutical qualities (e.g. USP or Ph.Eur) and food grades. In addition to the major elements Dr. Paul Lohmann® offers also all important trace elements such as e.g. selenium, copper, manganese and more. Furthermore the microencapsulation of mineral salts offers formulators considerable advantages: Ingredients not considered for the food fortification or for processing dietary products (e.g. highly bio-available ferrous sulfate that is highly reactive) can now be used without adverse sensory implications, such as, a strong metallic taste or changes in product color.


Directly compressible granules

The directly compressible granules (DC) of Dr. Paul Lohmann® allow direct processing of the basic material to tablet form without prior wet granulation with reduced need for additional binding. In the range are e.g.: Calcium Carbonate, Tri-Calcium Citrate, Tri-Magnesium Citrate or Ferrous Fumarate.

Bisglycinates, Mineral Chelates

Mineral chelates are molecules with a highly stable structure. The chelate structure is composed of two molecules of the amino acid glycine and one central metal atom. The chelate structure is a protective shield against outside influences like oxidation or absorption inhibitors and increases the bioavailability of the enclosed mineral. The bisglycinate portfolio of Dr. Paul Lohmann® contains Iron, Zinc-, Calcium-, Magnesium-, Copper-, and Manganese-Bisglycinate which are permitted for food supplements according to Directive (EC) No. 2002/461.

ALL THANKS TO UPSTART LOAN AM NOW FINANCIALLY STABLE . I am Michelle Huxford from Casper, Wyoming. I was in a very chronic financial issue and terminal health situation some few weeks back. After all my search for assistance from friends and neighbors proved abortive, I feel there was no one who truly cares. I became so emaciated due to lack of good food and my 2 kids age 5 and 8 were not also good looking due to lack of proper care as a result of finance. One faithful morning I saw an old time friend of my late husband and I told him all I have been going through and he said the only way he could help was to direct me to a good loan agency that also helped him, He explained to me on how he was financially down and how he got boosted by this loan agency UPSTART LOAN INC ( ) who grant him 245,000 USD loan at an affordable rate. He further assured me that they were the only legit loan firm he found in the quest of seeking for loan after been scammed by various fake loan lenders online. He gave me their email: or text/call (574) 301-1639, That was how i applied and was also granted a loan and my life changed for the good. CONTACT THE ONLY GENUINE LENDERS( UPSTART LOAN INC) VIA email: or call +1 (574) 301-1639 to resolve your financial mess.

How To Get Your Ex Husband Back Today ??? My husband and I have been married for 7 years and together for 11. We have 3 children, ages 16 months, 4 and 6. He recently left me and moved in with the woman he has been seeing for only 2 months. We have been living with my parents for a few years because I have been going through school and he has been just working security. He went through the police academy and has been having a hard time getting a police job. He is also in the Army National Guard. He was deployed in Afgahnistan Jan. 2014 – May 2015. I really think he has ptsd and depression. For the last few months he has been very distant from me and the kids. He hasn’t been hanging out with friends or doing activities he would normally do on a regular basis. He would kept saying we need to fix things. He would say I do this wrong and that. It was like he was trying not to love me. One day he’d kiss me and showed affection, we were still having sex, then the next day nothing. I’ve been trying to get him to see a counciler but he won’t. He has admitted he has PTSD and other issues but then other days he says he doesn’t. He thinks this women he is with now is his soul mate. He met her online and lied saying he has been divorced for two years. She has found out he’s married and still wants to be with him. I don’t see it working out. I love my husband so much, I hate what he has done. I just wish he would get some help if it is because of PTSD and depression. Do you think it might be? I still want him back. I was totally devastated and confused until a old friend of mine told me about a spell caster on the internet Chief Nwaluta Mallam Zack who help people with the relationship and marriage problem by the powers of love spells, at first I doubted if such thing ever exists but decided to give it a try, when I contact him, he helped me cast a spell and within 48hours my husband came back to me and started apologizing, now he has stopped going out with that lady and he his with me for good and for real. i want You my friends who are passing through All this kind of love problem of getting Back their husband, wife , or ex boyfriend and girlfriend to contact him on this Email: { } you can also contact him on his website .

I prefer the directly compressible granules. Maybe Creative Biolabs should also have a try.
