General Questions about Zinc

What is zinc?

Zinc is an essential mineral that is found within every cell of the human body. Zinc is required for normal growth and development, immune health, vision, reproduction, insulin regulation and thyroid function.  Zinc also has antioxidant properties and is a primary structural component of the antioxidant enzyme, superoxide dismutase. 

What are some risk factors for a zinc deficiency?

Severe zinc deficiency is considered to be rare in the developed world. However, marginal zinc deficiency may be much more common. Individuals that are at risk for zinc deficiency include—

  • alcoholics and those with gastrointestinal disorders such as persistent diarrhea, malabsorption syndromes, celiac disease, Crohn’s disease and ulcerative colitis;
  • pregnant and lactating women who need higher amounts of zinc to support healthy fetal development and, for this reason, may be at greater risk of deficiency;
  • strict vegetarians primarily due to the zinc-blocking effects of phytate, a compound present in some grains and legumes; and
  • senior citizens due to a reduced capacity to absorb zinc. Some medications may also decrease zinc absorption and limit its utilization in the body.

Are there any food sources of zinc?

Zinc can be found in a wide variety of foods. Oysters are considered to be the richest food source of zinc. Meat, eggs, and seafood also provide good amounts of zinc and are generally free of compounds like phytic acid, which may lessen absorption of zinc.  Vegetarian sources of zinc include leafy greens (bok choy, spinach, beet greens, swiss chard), mushrooms, sesame seeds, pumpkin seeds, cashews, quinoa, green peas, brussel sprouts, broccoli, oats, and sea vegetables.

What is the recommended dietary allowance for zinc?

The 100% daily value (%DV) for zinc for individuals 18 years of age and older is 11 mg. This goes up to 13 mg per day during pregnancy/breastfeeding. 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 zinc?

The Upper Tolerable Limit (UL), established by the Food and Nutrition Bard (FNB) of the Institute of Medicine, is considered to be the highest amount you can take of a nutrient without theoretical risk. The UL for zinc is 40 milligrams per day for adults. This UL was largely based on the concern that long term consumption of high amounts of zinc could result in copper deficiency, given that zinc and copper compete with each other for absorption in the human body.

Can zinc supplements be taken with OTC or prescription medications?

Taking zinc supplements at the same time as some medications may result in decreased absorption and efficacy of the medication and/or the zinc 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 Zinc Gold

What is the source of zinc in Zinc Gold?

Zinc Gold provides a gentle and nourishing form of  plant-based zinc from guava 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. 

How does Zinc Gold compare to other zinc supplements?

Zinc Gold is a gentle and nourishing form of plant-based zinc that is derived entirely from natural food sources—it is not synthetic zinc fermented, grown or cultured in yeast or a blend of organic foods fortified with synthetic zinc and marketed as “whole-food” or “food-based” zinc.

How does NutriGold ensure the purity of the ingredients used in its Zinc 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 zinc listed on the label (15 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 Zinc Gold? Should it be taken with food?

Zinc Gold is gentle 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 use, if any, is best for your individual needs.

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

Zinc 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 Zinc Gold is suitable and safe for your child’s particular healthcare needs prior to supplementation.
