Iron Gold

General Questions about Iron

What is iron?

Iron is a mineral required by the human body for growth and development. Every cell in the body requires oxygen to function and iron is an essential component of hemoglobin and myoglobin, which provide and carry oxygen to all parts of the body.

What are some risk factors for an iron deficiency?

Iron deficiency is the most common nutritional deficiency worldwide. Children, women of childbearing age, frequent blood donors, and individuals with certain medical conditions (e.g. malabsorption syndromes) are often most at risk. In addition, diets that are overly reliant on refined and processed foods can also pose challenges to achieving optimal iron intake.

How do I know if I need to supplement with iron?

While individuals with a mild iron deficiency may not experience or exhibit any obvious symptoms, those with a severe deficiency may experience fatigue, shortness of breath, or chest pain. It is never a good idea to self-diagnose or self-treat a health condition, so we encourage you to consult your healthcare provider prior to supplementation to determine if an iron supplement is appropriate for your individual needs.

Are there any food sources of iron?

Meat, poultry and fish, spinach, swiss chard, and parsley are all excellent dietary sources of iron.  Iron can also be found in a variety of plant-based foods like bok choy, brussel sprouts, kale, cabbage, asparagus, leeks, and lettuce. It may be important to note that plant sources of iron are in the non-heme form, which has lower bioavailability than the heme form found in meat, poultry, and fish. However, the quantity of non-heme iron in plant sources is much higher, so even with the lower bioavailability, non-heme iron contributes more in terms of nutrition than heme iron. Legumes such as soybeans, black beans and lentils may also contain decent amounts of iron but the phytic acid they contain may reduce iron absorption.  Certain methods of food preparation, such as soaking, sprouting, fermenting, and cooking, can reduce phytic acid content which may help improve iron absorption from these foods.

What is the recommended daily allowance for iron?

The 100% daily value (%DV) for iron for individuals 18 years of age and older is 18 mg. This goes up to 27 mg per day during pregnancy/breastfeeding. The body’s demand for iron is lower in some population groups (e.g. men, post-menopausal women), so, as with any supplement, please talk to your healthcare provider prior to supplementation to ensure you are following the dosing schedule that is right for your particular health needs.

Is there an established upper toxicity limit for iron?

The Tolerable Upper Intake Level (UL) is considered to be the highest amount you can take of a nutrient without theoretical risk. The Food and Nutrition Board (FNB) of the Institute of Medicine has based the tolerable upper intake level (UL) for iron at 45 mg per day. This amount is largely based on preventing symptoms of gastrointestinal distress (e.g. constipation) that can occur from excess iron intake from supplements or fortified foods.

Can iron supplements be taken with OTC or prescription medications?

Taking iron supplements at the same time as some medications may result in decreased absorption and efficacy of the medication and/or the iron supplement. If you are taking or planning to take an OTC or prescription medication, please consult a licensed pharmacist or your healthcare provider before beginning supplementation to minimize risk of side effects associated with potential supplement-drug interactions.

Questions about Iron Gold

What form of Iron does Iron Gold provide?

Iron Gold provides a gentle and nourishing form of  plant-based iron from curry leaf and other ingredients in the organic food blend. The full list of organic foods can be found under the ‘Organic Food Blend’ in the supplement facts panel (on the label) and on the product page on our website. Iron Gold is not synthetic iron fermented, grown or cultured in yeast or a blend of organic foods fortified with synthetic iron and marketed as “whole-food” or “food-based” iron. 

Does Iron Gold cause constipation or any other gastric discomfort?

Most iron supplements are synthetically created and, in high doses, can cause gastrointestinal side effects such as nausea and constipation. Although individual experiences can vary, Iron Gold is gentle, well-tolerated, and does not cause any digestive discomfort.

What is the purpose of the organic food blend in Iron Gold?

At Nutrigold, we are mindful of the fact that every ingredient in a product, regardless of whether it is an active ingredient that provides a health benefit or an additive that ensures finished product integrity, can and will likely have some impact on consumers’ health. This is why we are philosophically opposed to the use of synthetic, semi-synthetic, or commodity additives like magnesium stearate and silicon dioxide commonly found in most commercially-available supplements. We choose instead to use organic, plant-based, pantry-friendly functional additives that not only have a history of safe use, but may help support the bioavailability and absorption of iron from the curry leaf in the food blend.

How does NutriGold ensure the purity of the ingredients used in its Iron Gold product?

At NutriGold, we go above and beyond what is recommended or required under current GMPs to independently verify that the raw materials used in our products as well as the finished products themselves meet industry-defining quality and purity standards. Depending on the complexity of the testing involved, including determining what needs to be tested, what methods are fit-for-purpose, and which lab is most qualified to perform the testing, we sometimes have results from as many as 4 or 5 different independent, ISO-certified labs for each product. We take these results from third-party labs and summarize them in lot-specific Certificates of Analysis that are  freely available in the spirit of authentic transparency on the product pages on our website so consumers can make informed purchasing decisions.

What assurance can you provide that the amount of  iron listed on the label (18 mg) is actually in the product?

All of our products are verified by independent third-party labs to meet identity, purity, and potency label claims. We take these results from third-party labs and summarize them in lot-specific Certificates of Analysis (C of A) that are  freely available in the spirit of authentic transparency on the product pages on our website so consumers can make informed purchasing decisions. The C of A provides assurance that the claims made on the label accurately reflect the contents of the product inside the bottle. If interested, more information on our our commitment to independent, third party quality testing can be found at this link - https://nutrigold.com/pages/accountability  

What is the best time of day to take Iron Gold?

Iron Gold is gentle and easy-to-digest and can be taken anytime, even on an empty stomach. However, as a matter of principle and in the interest of your health and safety, we encourage you to consult your healthcare provider prior to supplementation to determine what dosing schedule is best for your individual needs.

Can I take more than 1 capsule per day?

Iron Gold provides 18 mg of plant-based iron in each 1 capsule serving, meeting 100% of the FDA Daily Value for Iron. If you are interested in or considering taking a higher dosage, we ask that you do so only under the guidance and supervision of your healthcare provider. 

Is Iron Gold safe during pregnancy?

To the best of our knowledge, our product should be safe for consumption by pregnant women because it provides gentle, plant-based iron that supports women’s health. That said, we must clarify that we consider women trying to conceive, already pregnant, or breastfeeding to be a vulnerable population and we strongly encourage you to talk to a qualified healthcare professional regarding use, benefits, and possible risks prior to supplementation.

What is a pullulan capsule? What is it made of?

Pullulan is a vegetable-derived, water-soluble polysaccharide produced through a natural fermentation process. Pullulan capsules are considered more natural than HPMC (cellulose) capsules because they are naturally derived from fermented tapioca. Unlike cellulose capsules, which are considered semi-synthetic and not permitted in certified organic products, pullulan is included in the USDA’s National Organic Program list of accepted ingredients for organic products. 

Can I break apart the capsule and add the contents to liquid/food to consume?

All of our products are formulated to be taken as capsules and our purity and potency claims are based on the product being taken as recommended. We generally do not recommend breaking apart the capsules because it can introduce contaminants or otherwise compromise product potency and effectiveness.

Is Iron Gold suitable for children (under 18 years of age)?

Iron Gold is formulated for individuals over 18 years. Because children are considered a vulnerable population, we regret we cannot make any recommendations regarding the use of our products by or for children under the age of 18. We ask that you talk to your pediatrician or family practitioner about whether or not Iron Gold is suitable and safe for your child’s particular healthcare needs prior to supplementation.

Please be advised that, per 21 CFR 101.17(e)(1), “Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control center immediately.”

Questions about capsule shell

What is in the capsules used by NutriGold to encapsulate its products?

Depending on the formulation, NutriGold products are encapsulated using cellulose, pullulan, organic pullulan, or soft gel capsules. Information regarding the composition of the capsule shell is provided in the “Informed Purchasing Decision Checklist” and is accurate to the best of our knowledge based on information available in the public domain as well as supply-chain documentation provided by the capsule and soft gel manufacturers/vendors.

Are any processing aids used in the production of the empty vegetarian capsule?

Yes. Minor amounts (~ 3%) of processing aids are used in the production of the empty vegetarian (cellulose) capsule shell. The processing aids used in the manufacturing of the capsule shell have been identified as proprietary by the capsule manufacturer and protected by intellectual property and confidentiality agreements between the capsule manufacturer/vendor and NutriGold. As such, we are legally bound to maintain this information strictly confidential and regret that we cannot provide this information to consumers. We can, however, assure you that the processing aids are non-toxic, generally recognized as safe (GRAS), compliant with both the United States Pharmacopoeia and European Pharmacopoeia, and do not pose an allergen risk.  

Are the processing aids used in the production of the empty capsule shells present in the finished product?

Processing aids that are used in the production of the capsule shell may be present in the finished empty capsule shell. We regret we cannot provide precise information on the type of processing aid(s) or the approximate residual amount of the processing aid(s) in the finished capsule shell because it would require us to divulge information proprietary to the capsule manufacturer. We can, however, assure you that the processing aids used in the production of the empty capsule shell are non-toxic, generally recognized as safe (GRAS), compliant with both the United States Pharmacopoeia and European Pharmacopoeia, and do not pose an allergen risk.

I am concerned about a possible allergy to the processing aid(s) used in the production of the capsule shells. How can I find out what processing aids are used so I can determine whether the product is safe for me to take?

Although we make every effort to provide as much information as we can about the ingredients in our products to help consumers make educated purchasing decisions, there may be times when we cannot provide the requested information or clarification because it is proprietary to the manufacturer, as in the case of the processing aids. Disclosing protected information to unauthorized individuals, within and outside our organization, is not just unethical, but also unlawful. If you are concerned about a potential allergy to the processing aid(s) that may have been used in the production of the capsule shell, we encourage you to discuss your concerns with your healthcare provider prior to making a purchasing decision. 

Why does NutriGold® sometimes use soft gelatin capsules to encapsulate its products?

At NutriGold®, we are committed to offering sustainable products using non-GMO, organic, and/or vegan ingredients, and this includes the capsule shell we use to encapsulate those ingredients. In fact, many of our products are certified vegan by Vegan Action®, helping provide unbiased assurance that the product (and the ingredients it contains) comply with both dietary and ethical vegan standards. However, there are some ingredients (e.g. fish oil, ubiquinol, astaxanthin) that are more sensitive to oxygen and can, consequently, oxidize or degrade. For ingredients like these, bovine gelatin soft gelatin capsule shells offer better protection and help ensure finished product integrity until the end of the shelf-life of the product. That being said, we are hopeful that growing consumer awareness of and demand for vegan options will continue to drive innovation in dietary supplement delivery systems and we are committed to replacing the gelatin soft gels in our products with a clean-label, vegan capsule shell that offers the same protection from the elements as the gelatin capsule when such an option becomes available.

Questions about the ‘Best By’ date and ‘Consume by’ recommendation

What does the “Best by” date printed on the bottom of the bottle mean?

The “Best By” date printed on the bottle is the date until which a product will meet label claims as long as the product is sealed or, once opened, stored and handled as recommended on the product label.

Is the product safe to take after the “Best by” date printed on the bottle?

As long as the product is stored and handled under conditions that will not cause it to become contaminated, the product should be safe to take past the “Best By” date printed on the bottom of the bottle. However, we do not guarantee that the product will meet stated label claims past the “Best By” date printed on the bottle.

Why does the product I purchased have a recommendation on the label to consume the product within a certain number of days after opening the bottle?

The “consume by” recommendation is included on products that are formulated using ingredients that are sensitive to environmental factors (e.g. heat, light, humidity). Although exposure to these environmental factors does not adversely impact or compromise product safety, it can degrade the potency of these eco-sensitive ingredients and, consequently, make the product less effective. So, to ensure that you get the most out of products that are made using eco-sensitive ingredients, please consume the product within the timeframe recommended on the label.

What is the difference between the “Best by” date and the “Consume by” recommendation on your products?

The “Best By” date printed on the bottle is the date until which a product will meet label claims as long as the product is sealed or, once opened, stored and handled as recommended on the product label.

The “Consume by” recommendation is included only on products that are formulated using ingredients that are sensitive to environmental factors (e.g. heat, light, humidity). Although exposure to these environmental factors does not adversely impact or compromise product safety, it can degrade the potency of these eco-sensitive ingredients and, consequently, make the product less effective. So, to ensure that you get the most out of products that are made using eco-sensitive ingredients, it is important to consume the product within the timeframe recommended on the label.

If the product I purchased contains ingredients that can degrade once the bottle is opened, how can I be confident that I am still getting the declared amounts of the nutrients on the label?

To ensure that our products provide the nutrients in the amounts declared on the label, we intentionally include higher amounts of eco-sensitive ingredients than what is declared on the label to compensate for degradation that may occur once the bottle is opened. The amount of an ingredient that is added above what is declared on the label is referred to as an intentional “overage” and it is added for the precise purpose of compensating for possible potency degradation during routine product storage and handling. That being said, we would like to assure you that we take great care to ensure that the amount of the overage does not exceed established tolerable upper limits and there is no risk of toxicity when the product is taken as directed.

Because there are practical and regulatory considerations on how much of an overage we can include in our different formulations, the most effective option we have available to ensure that consumers get the most out of our products is to provide the “consume by” guidance on products that contain eco-sensitive ingredients. You can be confident that you are getting the declared amounts of the nutrients as long as you store and consume the product within the recommended time frame.

Why do you recommend consuming the product within a certain number of days after opening the bottle even though the “Best by” date is months (or years) away?

NutriGold products are made with natural ingredients and without chemical preservatives. While the vast majority of ingredients we use in our products are stable and remain potent even after the product is opened, there are some ingredients that are particularly sensitive to environmental factors and must be handled with care from source to shelf, and beyond.

If the product you purchased includes a recommendation to finish the product within a prescribed time, it is important that you follow this guidance (unless it conflicts with instructions from your healthcare provider), so you can enjoy the health benefits that can only be realized when the product is taken consistently as recommended.

Will the product still provide benefits past the “consume by” recommendation on the bottle?

If the product you purchased includes a recommendation to finish the product within a prescribed time, it is important that you follow this guidance so you can enjoy the health benefits that can only be realized when the product is taken consistently as recommended. Although not consuming the product within the recommended time frame once the bottle is opened will not cause the product to “spoil” or become “unsafe,” the potency of some of the more eco-sensitive ingredients may start to degrade and this can diminish the product’s potential to support your health goals.

What is the best way to store NutriGold products?

NutriGold products are made with natural ingredients and without the use of any chemical stabilizers or preservatives. So, the best way to store them is in their original container away from direct sunlight and humidity. It is not recommended to empty the capsules or soft gels from their original container and store them in pill boxes or plastic bags because it could not only cause some of the more eco-sensitive ingredients to lose potency, but may also increase the risk of cross-contamination with other products or environmental pathogens.
