Modified starch of Vitamin D 1000 UI

In Vitamin D 1000 UI, where does the modified starch?

R/ Modified starch means cellulose from a plant which has been heated to form a stable fibrous material which is used as a tablet binding material.  The plant we use is corn for all supplements containing modified starch including vitamin D.  Customers commonly misunderstand the word “modified” and wrongly assume it means “genetically modified” but this is certainly not the case!  Also, bear in mind this is simply inert cellulose starch, so has no know allergenic properties and is widely found in the diet.

Difference between Ester C and our Vitamin C time release

Can you explain me the difference between Ester C and our Vitamin C time release?

R/ Lamberts Ester-C 650mg is also described as calcium ascorbate. This product is fast absorbed and, according to the US patent holder, is well retained in the body. They furthermore state that the manufacturing process involved creates other compounds called ‘metabolites’ of vitamin C, which are believed to impart certain properties to Ester-C. They claim that this product is an improved form of the C vitamin because it is considered to be more bio-available that ordinary vitamin C, leading to higher vitamin C levels inside cells which stay in the body longer and less is excreted in urine. Lamberts were the first company to launch Ester-C in the UK, hence why it is still on our range, however feedback from practitioners state that they prefer the time release formula. Others state they find little significant change between the two when testing and so prefer the time release form due to the higher dose compared to price equation. What we do know is that Ester-C is non acidic (it has a neutral PH in solution), which means that it is certainly a very gentle form of vitamin C, which may be useful for those who experience intestinal difficulties when taking acidic forms of vitamin C. This is the same as for the forms of gentle vitamin C and calcium ascorbate.

The Lamberts Vitamin C time release formulas do not contain any calcium but are a high strength product designed for convenience that retains its nutrient levels in micropellets allowing them to be released slowly after the tablet has been swallowed. The absorption of vitamin C is a continuous process over 6 – 8 hours which allows the gradually absorption of vitamin C into the blood stream. It is recommended that Vitamin C is best taken in small amounts throughout the day because it is rapidly lost from the body. The time release formulas also contain bioflavonoid’s and rosehips that have been found to aid vitamin C absorption.


2) In Vitamin D 1000 UI, where does the modified starch?


R/ Modified starch means cellulose from a plant which has been heated to form a stable fibrous material which is used as a tablet binding material.  The plant we use is corn for all supplements containing modified starch including vitamin D.  Customers commonly misunderstand the word “modified” and wrongly assume it means “genetically modified” but this is certainly not the case!  Also, bear in mind this is simply inert cellulose starch, so has no know allergenic properties and is widely found in the diet.

Origin of fishes of the Pure Fish Oil

About Pure Fish Oil 1100mg, the fish from which part of the world are they from?. Do you have detail of all 5 Stages Purification Process and Extraction Fish Method.

R/ The Lamberts Fish Oils are sourced from a range of different oily fish dependent on the season and availability and are not from farmed fish. We also sourced from seas all over the world, from where we can obtain the best quality. Sadly, due to human activity, no ocean is completely free from pollutants, but it is the highly sophisticated processing of fish oil which is important.

Lamberts insist on using premium grade fish oil which has undergone a sophisticated screening process to ensure that the oil is of the highest quality. Once the oil has been purchased, Lamberts use the least chemically-aggressive, solvent-free processes available to process fish oils that meet with strict quality control at all production stages.  The main features of the process include: (i) partial odour/bitter component reduction (ii) colour standardisation (iii) saturate reduction (cooling) (iv) secondary odour reduction (to reduce ‘reflux’ effects) and (v) filtration/molecular distillation to discard natural solid residues.

These tests include screening for a variety of contaminants such as aflatoxins, heavy metals, antibiotics, PCBs, dioxins, PAHs, irradiated ingredients and pesticides. We also add vitamin E to our fish oil concentrate to stabilize the oil and prevent them from oxidation. Furthermore, we hold minimal stock so that our products are freshly made. For added freshness, all our Fish Oil capsules are processed and packed in the UK.

Enzymatic Activity of Pepsine

Which is the enzymatic activity of pepsine?

R/ Pepsin is one of three principal protein-degrading (a.k.a. proteolytic) enzymes in the digestive system so it helps with the breakdown and digestion of dietary proteins. I have attached a research paper with more information. Pepsin is porcine (pork) and Betaine is synthetic. Both are highest grade possible.

Enteric cover in capsules of peppermint oil

Can you explain me that why is not advisable the enteric cover in capsules of peppermint oil?

R/ The Peppermint oil capsule does not have the enteric coating of medicinal products and so dissolves in the stomach – not just in the lower intestine. It is designed to be anti-spasmodic and smoothing for the stomach and its effect is also active lower down in the small intestine.

Is pharmaceutical grade?.Yes.

Extraction of the Sea Buckthorn

How is the extraction of the Sea Buckthorn?

R/ The Sea Buckthorn is a fatty oil extraction via Co2 extraction technique from the fruit. Co2 is one of the purest forms of extraction available and there is no pressing and no heat involved. The olive Oil in Omega 3,6,9 is cold pressed.

Premtesse & Magnesium forms

I have doubts. How is possible that the Premtesse tablets are so small compared with MagAsorb tablets if Premtesse have more Magnesium?.

R/ The clue would be in the form of magnesium.

So in Magasorb we use citrate whereas in Premtesse we use oxide. We always state the elemental magnesium in our formulas, so in this way Magasorb contains 150mg of pure magnesium and Premtesse contains 400mg of pure magnesium. This is the main difference as many competitors will cite the magnesium salt as the quantity and only few will cite the elemental quantity – for example one company cites.

Magnesium Succinate (providing 72mg elemental magnesium) 425mg

Oral magnesium supplements combine magnesium with another substance such as a salt. Examples of magnesium supplements include magnesium oxide, magnesium sulfate, magnesium carbonate and magnesium citrate.

Elemental magnesium refers to the amount of magnesium in each compound. Figure 1 compares the amount of elemental magnesium in different types of magnesium supplements:

Percent of magnesium in oral suppelements

Figure 1:Percent magnesium content y oral supplements


How to calculate the table: Mineral supplements are mostly salts – consisting of the cation (usually what you’re interested in) and an anion partner. Cations are positively charged; anions are negatively charged. You only care about the cation, and not the anion, so the anion essentially becomes a filler. Consider Magnesium Citrate. It has a molecular weight of 214.41 g mol. Magnesium has a molecular weight of 24.31. So Mg is 24/214ths or 11% Mg by weight. So every 100 mg of magnesium citrate has just 11 mg of useful Mg! Therefore you need a lot of Magnesium Citrate to make up 150mg of elemental magnesium found in Magasorb – hence the large tablets! Consider Magnesium oxide now. Molecular weight of 40.30, so 60% Mg by mass. 100 mg of magnesium oxide has 60 mg magnesium.

If you took Mg oxide with a meal (as we recommend for the Lamberts multi vitamins), you’d get a higher absorption. Citrate helps you absorb nearly all the Mg present, but it’s takes a lot of bulk to do so. Many people believe that 400mg of magnesium oxide – the whole salt – is a lot, but in reality only 8mg is actually absorbed. which is very little. As stated above our formulations only give the elemental value hence why we add the salt form as brackets alongside the word ‘magnesium’ in our technical catalogues.

Further to our own clinical testing conducted by Dr Sam Christie in a paper called ‘Mg citrate found more bio available than other Mg preparations in a randomised, double-blind study’ we added a Magnesium Citrate to our range alongside a Calcium Citrate product. The tablet size of these products are larger due to the citrate salt being a larger molecule and so for formulations where we need to feature magnesium or calcium alongside other nutrients we use the oxide or carbonate compounds.

The main use of magnesium oxide in our range is in Osteoguard and in our multi vitamins where we need to fit in many ingredients. Data to support these uses includes a 2006 study which specifically demonstrates the effectiveness of magnesium oxide on bone mineral content: ”A randomised controlled study of effects of dietary magnesium oxide supplementation on bone mineral content in healthy girls” (Clin Endocrinol Metab. 2006). Magnesium Oxide is a safe and tolerated source of dietary magnesium. One of the earliest uses in medical intervention spans from 1810 when magnesium oxide was used to treat patients with uric acid stones. A 2007 article published in the Archives of Biomedical Biophysics cites numerous studies to suggest magnesium oxide intake as a treatment for hypertension. More recently, the University of Maryland Medical Centre has stated that magnesium oxide may be used to restore magnesium levels, may allay migraines, high blood pressure and also assist in the treatment of arrhythmia.

However if the practitioner needs to address a magnesium deficiency quickly, then we would recommend magnesium citrate over magnesium oxide.

Omega 3´s way

The Omega 3 in what way is it?

R/ The Lamberts Omega 3 is derived from ethyl esters; the huge body of research on fish oil has been conducted using the ethyl ester form. As the Lamberts range is formulated on clinical evidence we have therefore taken the choice to maintain the ethyl ester form until further research is produced on triglyceride based fish oil.

What is the source of lactase?

What is the source of lactase?

 R/The Lamberts lactase is formed from Aspergillus Oryzae. Lactase produced commercially can be extracted both from yeasts such as Kluyveromyces fragilis and Kluyveromyces lactis and from fungi, such as Aspergillus niger and Aspergillus oryzae.

Lamberts use Aspergillus oryzae as a source which is a probiotic filamentous fungi commonly used in the fermentation process of soybeans, rice, grain and potatoes. It is used to make certain fermented Asian foods like tempeh, soy sauce, miso, sake, and rice vinegars. This fermentation process produces enzymes which are known to be beneficial to both humans and animals. In particular, aspergillus oryzae produces the enzyme amylase, an important enzyme for a healthy gut and good digestion. The Lamberts Lactase has an activity of 65,000 lactase units per gram.

Vitamin K: Production

What is the method of production of vitamin K?.

R/ Vitamin K- Lamberts Vitamin K is created through fermentation, specifically natto fermentation, is soy-free. Our supplier uses a brand new state of the art GMP plant to produce Vitamin K2.  The company we chose has over 100 years combined experience in deep tank fermentation and took 4 years to develop a completely unique and proprietary method of extracting vitamin K2-7 to achieve the highest concentrations, to avoid adulteration of the product and to keep by-product levels to a minimum.

Difference between folate and folic acid

What is the difference between folate and folic acid?.

R/ Folate occurs naturally in food, and folic acid is the synthetic form of this vitamin. We use folic acid in our supplements as this synthetic form, achieved through fermentation, is more bio available than the natural form. For example, folic acid is highly absorbed (85-95%) compared to the dietary form (50%). The folate (natural form) is easily damaged by cooking and processing, hence why folic acid is considered to be more beneficial for health.
