Vitamin A

Isn’t Vitamin A dangerous to use during Pregnancy?

Vitamin A is essential for pregnancy as it is important for immune function and development of the eyes and prevention of night blindness. However, excessive quantities of Vitamin A can be teratogenic during pregnancy with the limit being not more than 10 000 IU of Vitamin A daily. Our pre-natal products only contain 1 000 IU of Vitamin A per day.

What is the difference between Vitamin A and Beta-Carotene? Is Beta-Carotene safer to use than Vitamin A?

Beta-Carotene is a water soluble vitamin and Vitamin A is a fat soluble vitamin. However, both Beta-Carotene and Vitamin A get converted into Retinol in the body. Thus, whether you use Beta-Carotene or Vitamin A caution must be taken not to exceed 10 000 IU daily.



Are our products Bioavailable?

We use bioavailable forms of vitamins and minerals where possible in our products.

In our prenatal supplements, we use Active Extrafolate-S as 5-MTHF, which is the metabolically active form of folate and does not need to be broken down by the body before use.

In our Bone, Joints and Muscles supplements we use Type 1 Hydrolysed Collagen, which is the form of collagen found in the organic bone matrix. It does not need to be broken down and can be used immediately. Type 1 Hydrolysed Collagen is a low molecular weight peptide, which is easily digestible and absorbable by the human body.



What type of Calcium is used in our products?

Calcium Carbonate.

The reason we use Calcium Carbonate in our products is because Calcium Salts are very bulky materials. To achieve a 500mg (500 mg) elemental dose in a swallow tablet we use 1250 mg Calcium Carbonate as it is the least bulky of all the salts with a 40% Elemental Value. Calcium Carbonate is also very widely available and cost effective and is the most stable of the salts. To improve the bioavailability of calcium carbonate, it is best taken at night with a meal.


What type of Chondroitin is used in our products?

Chondroitin Sulphate.

Clinical Trials

Have there been any clinical trials done on our products?

No, however, there have been clinical trials done on the raw materials / ingredients used in our products. Our products are CAMs products (Complementary and Alternative Medicines) and do not need clinical trial testing like registered medicines.

Co-Enzyme Q10

Does Co-Enzyme Q10 affect patients on warfarin?

Co-Enzyme Q10 may decrease or increase the anti-coagulant efficacy of warfarin. An individual on warfarin should not begin taking Co-Enzyme Q10 without first consulting their doctor.


Is the collagen in our products digested?

No, we use Type 1 Hydrolysed Collagen which is the bioavailable form of collagen peptides. This is the type of collagen found in the bone matrix. The body does not need to break it down; it is ready for use.


Easy Sleep 40winx

Can pregnant women safely take Easy Sleep40winx?

We would advise that pregnant women avoid Easy Sleep 40winx as it contains herbal ingredients. We would rather recommend our Stellar-Mama during pregnancy as it contains a high elemental amount of Calcium and Magnesium which are natural aids in sleep.



Can pregnant women safely take Flexi-CAL?

We would advise that pregnant women avoid Flexi-CAL. We suggest Stellar-Mama, Preggy-Mama, Stellar Activ-Folate or Opti-Cal during pregnancy.



Are our products Halaal?

Some of our raw materials like the chondroitin and collagen are sourced from Halaal bovine sources.

Each of our products states what is contained in them and who the product is suitable for.

Stellar-Mama, Preggy-Mama, Stellar Activ-Folate, InsuMax-Q, VasQ10, Repleni-Mag and Easy Sleep 40winx are Halaal (SANHA Approved).


Do our products have any impact on heart medication?

Individuals with heart issues should always consult their physician first before taking any supplementation.



What is the benefit of Iron Amino Acid Chelate?

Iron Amino Acid Chelate also known as Ferrous Bisglycinate (which is used in our products) is in a form that is readily absorbable, softer on the stomach and has a lower side effect profile (i.e. it does not give you constipation, black stools or nausea).



Can someone with kidney problems take Flexi-CAL?

Individuals with kidney problems should always check with their Physician/Nephrologist about any supplement before proceeding to take it. In general, dietary supplementation should be monitored in all patients with renal dysfunction.

Vitamin K

What is the difference between Vitamin K1 and Vitamin K2?

Vitamin K1 has a key role in helping the blood clot, preventing excessive bleeding. Taking Vitamin K1 and Warfarin are not compatible.

Vitamin K2 has two key roles. It activates Osteocalcin which helps calcium bind to the bone for bone strength and it activates Matrix GLA protein that helps to prevent arterial calcification. Vitamin K2 does not interfere with Warfarin.



What is the absorption rate of Magnesium Oxide versus other Magnesium salts?

The absorption rate is related to the quantity of elemental Magnesium present. Magnesium Oxide has a 60% conversion factor which is higher than other salts.



What kind of Omega do we use in our products?

Mostly derived from Tuna. However, no standardised fish oil can be guaranteed to be from a single source as different oils are blended to obtain the desired ratio of EPA and DHA.

The manufacturer of the fish oil is registered with the Global Organization for EPA&DHA Omega 3’s (GOED – see It has various quality certificates such as International Fish Oil Standards (IFOS) 5 Star Certificate, COS CEP Certificate, US-DMF Certificate which addresses quality standards in the US as well as Europe.

The factory processes fish oils only, no other animal products.

The fish gelatin for the capsules is derived from Tilapia.



Can pregnant women safely take Repleni-MAG?

Repleni-Mag is not a prenatal supplement and would rather suggest using Stellar-Mama or Preggy-Mama. We would advise that pregnant women avoid Repleni-MAG. We suggest Stellar-Mama or Preggy-Mama as a prenatal supplement.



If someone is taking warfarin, can they safely take our products?

Yes, they can, but they should also check this with their physician before use.
