FAQ

Two products, both vegan and sugar-free. On Call D3 delivers 2,000 IU (50 mcg) of plant-based Vitamin D3 from algae. On Call B-12 delivers 500 mcg of Vitamin B-12 (cyanocobalamin). Both use allulose and monk fruit instead of sugar, with a pectin (not gelatin) base.

We set each dose to match what your body actually uses, then confirm it sits safely within established limits. For D3, the NIH Office of Dietary Supplements points to around 2,000 IU a day as a meaningful amount for adults, comfortably below the 4,000 IU upper limit. For B-12, the body absorbs only a small fraction of an oral dose, so 500 mcg reliably covers what you need. Every dose is chosen by our physicians to be both safe and genuinely effective.

Yes, both products. The D3 is sourced from algae rather than lanolin, the gummy base uses pectin instead of gelatin, and there are no animal-derived colors or flavors.

Yes. We sweeten with allulose and monk fruit. Total carbs are 2 g per gummy, with no added sugar.

No. On Call Gummies are sweetened with allulose and monk fruit, with 5 calories per gummy. D3 is pineapple. B-12 is strawberry. The point is a simple one-gummy serving, not a candy-style sugar load.

On Call Gummies are sugar-free, nut-free, gluten-free, plant-based, and cruelty-free, manufactured in a cGMP-certified facility.

Manufactured in the United States in a cGMP-certified facility and third-party tested for purity and potency.

D3 is natural pineapple and B-12 is natural strawberry. Neither tastes like a vitamin.

D3 and B-12 are familiar nutrients with well-described jobs, which makes them a useful place to start. Vitamin D3 plays a role in calcium absorption, normal bone health, and normal immune function. Vitamin B-12 supports normal red blood cell formation, neurological function, and DNA synthesis. On Call Gummies started with these two because the category did not need a louder label. It needed a simpler one.

On Call B-12 uses cyanocobalamin, a common, stable form of vitamin B12. NIH ODS notes that B12 supplements commonly use cyanocobalamin and that research has not shown one supplemental form is better than another.

The point is not a louder form name. It is a clear 500 mcg amount, a label that says what it means, and a gummy people can keep using.

Not automatically. A supplement dose has to sit inside useful and safe ranges, not just look impressive on the front of a bottle.

On Call D3 provides 50 mcg, 2,000 IU, of vitamin D3. On Call B-12 provides 500 mcg of cyanocobalamin. The point is not the biggest possible number. The point is the selected daily amount, then a gummy built around that amount.

The one-gummy serving is not a convenience claim. It is the dosing philosophy.

On Call D3 provides 50 mcg, 2,000 IU, of vitamin D3. On Call B-12 provides 500 mcg of cyanocobalamin. Each formula starts with the evidence-based daily dose first, then the gummy is built around that amount. The format follows the dose, not the other way around.

One gummy a day. Each bottle is 30 gummies, a 30 day supply.

Yes. Plenty of people take one of each every morning. As a launch offer, add both to your cart and $10 comes off automatically, bringing the pair to $75.

Whenever you will remember. D3 absorbs better alongside a meal that contains fat, so a normal breakfast or lunch is ideal.

Yes. Supplements can interact with prescription medicines, over-the-counter medicines, other supplements, and surgery plans. NIH Office of Dietary Supplements gives examples including vitamin K with warfarin and St. John's wort with many medicines. FDA advises talking with a doctor, pharmacist, or other health care professional before using a dietary supplement, especially when medications or other supplements are involved.

General education only. Individual supplement decisions belong with a clinician who knows the full history.

Talk to your healthcare provider before starting. We can't replace your physician's judgment.

Vitamin D is often listed two ways: micrograms and International Units. They are two labels for the same amount. On Call D3 is 50 mcg, which equals 2,000 IU.

The conversion is there so the bottle is easy to compare with official vitamin D references and with older labels that still use IU. The dose itself does not change because the unit changes.

Vitamin B-12 is measured in micrograms because the amounts involved are small. That does not make the label simple. The NIH Office of Dietary Supplements notes that B-12 absorption depends on dose, and absorption decreases when the capacity of intrinsic factor is exceeded.

On Call B-12 is 500 mcg cyanocobalamin. Cyanocobalamin is a common supplemental form of B-12, and the NIH notes that no evidence indicates absorption rates vary by supplemental form.

The useful question is not whether the number is the biggest number on the shelf. The useful question is whether the amount, form, and label are clear enough to understand.

If you have a diagnosed deficiency, symptoms, pregnancy, medication questions, or a clinician-directed plan, ask your own clinician. They know your history.

Store On Call Gummies in a cool, dry place with the lid closed. A kitchen cabinet or desk drawer is usually a better choice than a hot car, a sunny windowsill, or a steamy bathroom.

The gummies are made to be simple to keep around, but heat and moisture are still not friendly to supplements. If the bottle has been exposed to unusual heat for a long time, use your judgment and contact On Call Gummies before using it.
