Why Smarter Exists

Built on formulas, not fame.

Smarter Vitamins wasn't built with celebrity endorsements, influencer hype, or trendy marketing. We built it the harder way: make thoughtful formulas, show you what's inside, and let the product earn the repeat order.

Clear labels. No proprietary blends. Ingredients chosen for a reason - not because they look good in an ad. 800,000+ orders later, we're still doing it the same way.

Why Smarter D3

Sunlight varies. Your serving doesn't.

How much vitamin D your skin makes from sunlight can change with the season, latitude, time of day, age, skin pigmentation, and how much skin is exposed. A supplement gives you a clearly labeled amount without guessing.

The Season Matters

UVB exposure changes throughout the year, which can change how much vitamin D your skin is able to produce.

Where You Live Matters

Geography affects the amount of UVB radiation available for vitamin D production, particularly during parts of the year.

Sunlight Isn't Constant

UVB intensity changes throughout the day, so the same amount of time outdoors does not always mean the same UV exposure.

Everyone Responds Differently

Melanin affects vitamin D production in the skin, so equal sun exposure does not produce the same response in everyone.

Age Makes a Difference

The skin's ability to produce vitamin D from sunlight decreases with age.

A Sunny Window Isn't the Same

The UVB wavelengths responsible for vitamin D production do not pass through ordinary window glass.

Exposure Varies

Clothing, shade, and the amount of skin exposed all affect how much UVB reaches the skin.

Know What You're Taking

Each mini softgel provides a clearly labeled 5,000 IU (125 mcg) of vitamin D3, with an every-other-day Suggested Use.

Good to know

FAQs

Each mini softgel contains 125 mcg (5,000 IU) of vitamin D3.

The Suggested Use is one softgel every two days with a meal. This product is not labeled for one softgel every day unless otherwise directed by a healthcare professional.

5,000 IU is a concentrated amount of vitamin D3, which is why the Suggested Use is one softgel every two days rather than daily.

Pay attention to vitamin D from all supplements you use, including multivitamins and combination products. If you are unsure how much vitamin D is appropriate for you, speak with a healthcare professional.

Vitamin D helps the body absorb calcium and supports normal bone health.*

It also plays roles in normal immune and muscle function.*

Vitamin D3 is cholecalciferol, while vitamin D2 is ergocalciferol.

Both forms can raise vitamin D levels, but research generally finds that D3 raises blood levels of 25-hydroxyvitamin D more effectively and can maintain those levels for longer.

Smarter Vitamin D3 uses cholecalciferol.

Vitamin D is fat-soluble, and the presence of dietary fat can enhance its absorption.

Smarter Vitamin D3 uses 100 mg of extra-virgin avocado oil as the oil carrier inside the softgel. We still recommend taking the softgel with a meal.

Your skin can produce vitamin D when exposed to UVB radiation from sunlight.

However, the amount produced can vary with season, latitude, time of day, age, skin pigmentation, clothing, and other factors. UV exposure also carries skin-damage risks, so deliberately increasing UV exposure simply to obtain vitamin D is not necessarily the best strategy.

A supplement provides a clearly labeled amount without requiring you to estimate what your skin produced.

Potentially, but check the labels of everything you take.

Multivitamins and other supplements may already contain vitamin D, so include those amounts when considering your total intake.

Vitamin K2 is a separate nutrient. You do not need to take K2 simply because you take vitamin D unless your healthcare professional recommends it for your individual needs.

The standard blood marker used to assess vitamin D status is 25-hydroxyvitamin D [25(OH)D].

Routine testing is not necessary for every healthy person, but a healthcare professional may recommend testing based on your health history, risk factors, supplement use, or other circumstances.

Consult a healthcare professional before use if you are pregnant or nursing, take prescription medication, have kidney disease, have a condition affecting calcium levels, or have been advised to limit or closely monitor vitamin D intake.

Certain medications can also interact with vitamin D or affect vitamin D metabolism.

No.

The vitamin D3 is derived from lanolin, and the softgel shell contains bovine gelatin. This product is therefore not vegetarian or vegan.

Each bottle contains 90 mini softgels.

When used as directed - one softgel every two days - one bottle lasts approximately six months.
