General Questions about Vitamin D

What is Vitamin D?

Vitamin D is a fat-soluble vitamin with many functions in the human body including supporting calcium absorption, bone, dental, immune, breast and prostate health.

What are some risk factors for a vitamin D deficiency?

Vitamin D is a common nutrient deficiency in the United States. Groups that are at high risk for developing vitamin D deficiency include: 

  • individuals who primarily work indoors with limited sun exposure;
  • individuals with dark skin because their skin has less ability to produce vitamin D from the sun;
  • obese individuals because their body fat binds to vitamin D, which prevents it from getting into the blood; and
  • older adults because their skin doesn't make vitamin D when exposed to sunlight as efficiently as it does in younger individuals. 

It may be important to note that those who live in northern climates, where the intensity of UVB radiation tends to be less, often make insufficient amounts of Vitamin D and people with gastrointestinal disorders or malabsorption syndromes may also be at an increased risk for deficiency.

Are there any food sources of Vitamin D?

One of the main sources of vitamin D comes from sunlight as it stimulates vitamin D synthesis in the skin. There are a few reliable food sources of vitamin D as well including salmon, tuna, sardines, and eggs.  Some foods are fortified with vitamin D such as milk, cereal and juices. However, these fortified foods may sometimes contain the less bioavailable Vitamin D2 (ergocalciferol) form.

What’s the difference between Vitamin D2 and Vitamin D3?

Vitamin D2 (ergocalciferol) is a form of vitamin D found in some plants, mushrooms, and yeast.  Vitamin D3 (cholecalciferol) is the form made by the body when the skin is exposed to UVB radiation from the sun. Vitamin D3 can also be found in dietary supplements produced from lanolin or lichen. Evidence suggests that vitamin D3 may be more effective than D2 in maintaining stable vitamin D levels in the human body.

Is it necessary to take vitamin K with vitamin D?

Vitamin D and vitamin K work synergistically to support proper calcium absorption in the body. While vitamin D promotes the absorption of dietary calcium and helps maintain blood calcium levels, vitamin K helps activate specific proteins that direct calcium to bones and teeth. Vitamin D and vitamin K work together to support both bone and cardiovascular health.

Some customers prefer the convenience of getting both vitamins in one product. If interested, we make a combination product called K2 + D3 Gold. 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 the recommended dietary allowance for vitamin D?

The 100% daily value (%DV) for vitamin D for individuals 18 years of age and older is 20 mcg (800 IU). This goes down to 15 mcg (600 IU) 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 Vitamin D?

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 established for Vitamin D in adults is 100 micrograms (4,000 IU) per day. However, it is common for a medical provider to determine that a larger amount of Vitamin D is necessary in cases of severe deficiency.

Can vitamin D supplements be taken with OTC or prescription medications?

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 Vitamin D3 Gold

What is the source of vitamin D in Vitamin D3 Gold?

All of our Vitamin D3 Gold products feature vitamin D from wild-crafted, sustainable lichen. Lichen is a complex life form that represents a symbiotic partnership of two separate organisms—fungi and algae. Lichen is an organic-compliant, vegan, kosher, allergen-free, non-GMO verified source of bioavailable vitamin D (as D3 cholecalciferol).

Is lichen-sourced vitamin D3 safe for human consumption?

Yes, lichen has been historically consumed in Europe, Asia and America as human food. The vitamin D3 in our product is sourced from Reindeer Lichen, a species of lichen traditionally used by Native Americans as food. Our wild-crafted lichen is not treated with any pesticides, collected using an environmentally-friendly and sustainable method, and gently extracted using food-grade ethanol only. In addition, lichen is an organic-compliant, vegan, kosher, allergen-free non-GMO verified source of bioavailable D3, which is consistent with our commitment to making the cleanest supplements using the purest and most sustainable ingredients available.

Which source of Vitamin D is more bioavailable - lichen or lanolin?

There should be no difference in bioavailability between vitamin D from lichen and vitamin D from lanolin. Both sources provide vitamin D as cholecalciferol, the form made in skin upon exposure to sunlight.

How do I know which Vitamin D3 Gold product is right for me?

NutriGold offers 4 different formulations of vitamin D3 with varying potencies—1000 IU, 2000 IU, 2500 IU, and 5000 IU. The decision on the vitamin D supplement that is right for your particular health needs should be made in consultation with and under the guidance of your healthcare provider. Contrary to popular belief, more is not always better, and there can be very real adverse consequences to taking a higher dose of vitamin D than what is needed to maintain optimal health. 

Is Vitamin D3 Gold certified organic?

Vitamin D3 Gold is made from wild-crafted lichen and wild-crafted products cannot be certified organic at this time. However, our lichen source is not exposed to any industrial pesticides or agricultural chemicals and is considered compliant with organic farming practices in terms of purity and sustainability.

How does NutriGold ensure the purity of the ingredients used in its Vitamin D3 Gold products?

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  vitamin D3  listed on the label 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 Vitamin D3 Gold? Should it be taken with food?

Most fat-soluble vitamins (e.g. A, E, K) are better absorbed when consumed with dietary fat (usually a component of most meals). Research demonstrates, however, that the amount of fat that is consumed with oral supplementation of vitamin D does not significantly modify the bioavailability of vitamin D3. Given this, Vitamin D3 Gold 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.

Why does Vitamin D3 Gold contain tapioca maltodextrin?

At NutriGold, we are philosophically opposed to the use of chemical additives and synthetic preservatives in our products. For this reason we avoid magnesium stearate and silicon dioxide as well as additives commonly sourced from GM ingredients like corn starch, corn maltodextrin, and soy lecithin. Although we make every effort to manufacture products without the use of any additives, there may be situations when an additive may be required to ensure production efficiency and finished product integrity. When that happens, we take care to use plant-based additives like the tapioca maltodextrin in our Vitamin D3 Gold. 

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 Vitamin D3 Gold suitable for children (under 18 years of age)?

Vitamin D3 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 Vitamin D3 Gold is suitable and safe for your child’s particular healthcare needs prior to supplementation.

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.
