Frequently Asked Questions – Vitamin Armor

Yes. Vitamin Armor supplements are manufactured in the United States in FDA-registered, GMP-certified facilities using globally sourced ingredients.

Vitamin100 Multivitamin is fully vegan-friendly. The capsules are made from vegetable cellulose, and there are no animal-derived ingredients anywhere in the formula. 

Vitamin Armor D3 is vegetarian-friendly but not vegan. The vitamin D3 in that product is derived from lanolin, a natural substance sourced from sheep’s wool. This makes it a non-fish-sourced, vegetarian option, but it is not suitable for strict vegan diets.

Vitamin Armor was originally formulated with athletes in mind, but the products serve anyone who wants clean, balanced daily nutrition. That includes active adults, busy professionals, parents, college students, veterans, and anyone who prefers a transparent, physician-formulated supplement over the megadose products that dominate the market. You can learn more about how the products fit different lifestyles on our Athletes and Active Lifestyles pages.

Yes. Both Vitamin100 and Vitamin D3 are formulated to be free from wheat, milk, casein, peanuts, tree nuts, fish, shellfish, dairy, lactose, soy, sugar, gluten, and eggs. You can always review the full Supplement Facts panel on each product page for complete ingredient details.

Proprietary blends group multiple ingredients under a single combined weight without telling you how much of each one is actually in the product. This makes it impossible to evaluate whether the amounts are meaningful or just there for label decoration. Vitamin Armor lists every ingredient with its specific form and exact amount so you always know what you are taking and can make an informed decision. For more on why this matters, read our blog post on what “no proprietary blends” actually means.

The amount of vitamin D commonly found in multivitamins is typically too low to meaningfully impact blood levels for people who are actually deficient. Many individuals require 1,000 to 5,000 IU daily based on blood testing, which is difficult to achieve within a standard multivitamin format.

Vitamin D is better dosed separately, allowing for individualized supplementation based on your actual needs and lab results. That is why we offer Vitamin Armor D3 as a standalone product at 5,000 IU per capsule. To learn more about how to tell if you need a vitamin D supplement, read our post on 5 signs of vitamin D deficiency.

Iron needs vary widely depending on age, gender, and pregnancy status. Iron supplementation often causes side effects such as nausea or constipation and may mask underlying anemia if taken without medical supervision.

Because iron also competes with other minerals for absorption and carries potential risks when taken unnecessarily, Vitamin100 does not include it. Iron supplementation is best guided by a healthcare provider based on blood work.

More is not always better. Each vitamin and mineral has a beneficial range as well as potential toxic levels. Excessive intake, especially of minerals like zinc, can lead to imbalances such as copper deficiency. Water-soluble vitamins taken in excess are simply excreted, which means you are paying for nutrients your body cannot use.

Vitamin100 is designed to provide 100% of essential daily values, supporting optimal intake when combined with a normal diet without the risks or waste associated with excessive dosing.

Yes. Vitamin100 is designed for daily, long-term use when taken as directed. Every nutrient is dosed at or near 100% of the Daily Value, which is the amount established as safe and effective for most healthy adults.

If you are pregnant, nursing, have a medical condition, or take medications, consult your healthcare provider before use.

Yes. Vitamin100 provides 400 mcg of folic acid, which is the amount commonly recommended during pregnancy to support fetal development. Iron needs during pregnancy vary, and Vitamin100 does not contain iron, which often improves tolerability.

Follow your obstetrician’s guidance on whether separate iron supplementation is necessary.

With a meal, ideally in the morning or at midday. Taking it with food supports absorption, especially for the fat-soluble vitamins (A and E) in the formula. The B vitamins support energy metabolism, so earlier in the day tends to work better for most people.

The most important thing is consistency: pick a time that fits your routine and stick with it.

Vitamin D3 is generally safe when taken as directed. Because it is fat-soluble, it is stored in the body rather than excreted, which means long-term use at very high doses should be guided by periodic blood testing. At 5,000 IU per day, Vitamin Armor D3 falls within the range commonly recommended by healthcare professionals for adults with insufficient levels.

If you are pregnant, nursing, or taking medications, consult your physician before starting any supplement.

Vitamin D needs vary by individual. As a general reference, 1,000 IU of vitamin D may raise blood levels by approximately 10 ng/mL. Dosing should be adjusted based on your baseline levels and follow-up testing under medical guidance. Most experts recommend maintaining serum levels above 30 ng/mL, with some suggesting 40 to 50 ng/mL as an optimal target.

Yes. Vitamin D levels are often lower during winter months and higher during summer due to changes in sun exposure. People in northern climates, those who work indoors, and anyone who consistently wears sunscreen may see more significant seasonal drops. Some individuals adjust supplementation seasonally to maintain consistent levels year-round.

Excess vitamin D may cause elevated calcium levels, which can lead to symptoms such as nausea, vomiting, constipation, weakness, confusion, kidney stones, or heart rhythm disturbances. This is uncommon at standard supplementation doses (1,000 to 5,000 IU daily) but is possible with prolonged use at much higher levels.

Any concerning symptoms should be evaluated by a healthcare professional.

Yes. Vitamin100 and Vitamin D3 were specifically formulated to work together without unnecessary nutrient overlap. Vitamin100 does not contain vitamin D, so adding D3 gives you targeted support without doubling up on anything. This allows for flexible, personalized supplementation based on your individual needs.
