Is this strength right for you?
Each capsule contains 5,000 IU of vitamin D3. This exceeds the general adult upper intake level of 4,000 IU per day. Ask your healthcare professional whether this dose is appropriate, considering your health, medications, and total supplement intake.
THREE NUTRIENTS. DISTINCT ROLES.
Vitamin D3
Supports calcium absorption and normal bone mineralization.*
Vitamin K2 as MK-7
Supports the activation of vitamin K-dependent proteins involved in normal bone metabolism.*
Vitamin A
Supports normal immune function and cell differentiation.*
One capsule brings these nutrients together without adding three separate products to your routine.
THE BIGGER PICTURE
There’s more to bone health
than calcium alone.
Calcium is an important building material for bones. Your body also relies on nutrients that support how calcium is absorbed and how bone-related proteins function.
Vitamin D helps your body absorb calcium. Vitamin K contributes to the activation of proteins involved in normal bone metabolism.*
That’s the reason to understand the formula—not simply count the number of ingredients on the label.
ADK 5 combines D3 and K2 with vitamin A in one capsule. It fits into a broader approach that includes adequate nutrition, appropriate physical activity, and individualized healthcare guidance.

01 / VITAMIN D3
Supporting calcium absorption.*
Vitamin D helps the intestine absorb calcium and supports the conditions needed for normal bone mineralization.*
ADK 5 provides vitamin D as cholecalciferol, also called D3.
Why the amount matters
A higher amount is not automatically a better choice for every person. This formula contains 5,000 IU per capsule, so its suitability should be reviewed with your healthcare professional.
Remember to count vitamin D from other supplements, including multivitamins and combination formulas.

02 / VITAMIN K2
Supporting bone-related proteins.*
Vitamin K acts as a cofactor for an enzyme that activates certain proteins. These include osteocalcin, a protein involved in normal bone metabolism.*
ADK 5 uses the MK-7 form of vitamin K2.
What that does—and doesn’t—tell us
An established biological role helps explain why a nutrient matters. It does not establish that this bottle prevents fractures or produces a particular change in bone density.
Medication consideration: Vitamin K can interact seriously with warfarin and similar anticoagulants. Consult your prescribing clinician before starting this product or changing your vitamin K intake.

03 / VITAMIN A
An essential nutrient with its own role.*
Vitamin A supports normal immune function, vision, and cell differentiation.*
ADK 5 contains preformed vitamin A as retinyl palmitate.
Consider your complete routine
Check for vitamin A in your multivitamin and other supplements. If you are pregnant, planning pregnancy, or breastfeeding, consult your healthcare professional before use.

EVIDENCE, IN CONTEXT
Research worth
understanding.
What has been studied?
Researchers have examined vitamin D and vitamin K in different populations, at different doses, and over different periods. Results need to be interpreted in that context.
The studies below investigated individual nutrients. They did not test the finished ADK 5 formula.
MK-7 / 2013 / 3 YEARS
Vitamin K2 and bone measurements
A 2013 randomized, placebo-controlled study followed 244 healthy postmenopausal women for three years. Participants received 180 mcg of MK-7 daily or placebo.
Researchers reported less decline in bone mineral density at the lumbar spine and femoral neck, but not the total hip.
Keep in perspective: The participants were postmenopausal women, and the dose differed from ADK 5. These findings do not establish the same effects in men, other populations, or users of this formula.
Three-year low-dose menaquinone-7 supplementation helps decrease bone loss in healthy postmenopausal women.
https://pubmed.ncbi.nlm.nih.gov/23525894/ ↗VITAMIN D3 / 2022 / 25,871 ADULTS
Vitamin D and fracture outcomes
A large 2022 randomized trial evaluated 2,000 IU of vitamin D3 daily in 25,871 midlife and older adults over a median of 5.3 years.
Supplementation did not significantly reduce fractures compared with placebo. Participants were not selected for vitamin D deficiency, low bone mass, or osteoporosis.
Keep in perspective: Vitamin D has essential physiological roles, but supplementation should not be presented as a guaranteed way to prevent fractures.

A FEW GOOD QUESTIONS
Before you
choose your routine.
What is ADK 5?
ADK 5 is a dietary supplement from Biote that combines vitamins A, D3, and K2. Each bottle contains 90 one-capsule servings.
Why combine vitamin D3 and K2?
They have different roles in normal bone physiology. Vitamin D supports calcium absorption, while vitamin K supports activation of proteins involved in bone metabolism.* Combining them offers convenience; it does not establish that a combination supplement is clinically superior for everyone.
Does ADK 5 contain calcium?
Calcium is not listed as an active nutrient in this formula. ADK 5 should not be counted as a calcium supplement or a replacement for adequate dietary calcium.
Is 5,000 IU of vitamin D3 appropriate for everyone?
No. It exceeds the general adult upper intake level of 4,000 IU daily. A healthcare professional can help determine whether this strength is appropriate for you.
How do I take it?
The listed directions are one capsule daily, or as directed by your healthcare practitioner. Review the current label and confirm that the formula and dose fit your needs before starting.
Can I take it with my multivitamin or other supplements?
Possibly, but first check for overlapping vitamins A, D, and K. Ask your healthcare professional to review your total intake.
Can I take it while using warfarin?
Do not start ADK 5 without guidance from your prescribing clinician. Vitamin K can alter the effects of warfarin and similar anticoagulants.
What if I’m pregnant, planning pregnancy, or breastfeeding?
Consult your healthcare professional before use. This product contains preformed vitamin A and a higher-dose vitamin D formulation.
Is it gluten-free, dairy-free, and soy-free?
The product listing identifies it as free of gluten, dairy, and soy. Review the current packaging for the latest ingredient information.
How long does one bottle last?
At the listed serving of one capsule daily, one bottle provides 90 days of use.
How quickly will I notice a difference?
There is no established timeline for a noticeable effect from this finished formula. Nutrient support may not produce a sensation you can feel, and individual needs vary.
Is ADK 5 a treatment for osteoporosis?
No. It is a dietary supplement, not a treatment for osteoporosis or a substitute for prescribed care.
Is shipping free?
Yes. This ADK 5 offer includes free shipping with no minimum purchase. Shipping is available to eligible U.S. addresses.
