A bottle labeled “vitamin D and K2” still leaves a major question unanswered: which K2 form does it contain? In this lineup, Designs for Health Vitamin D Supreme uses MK-4 alongside vitamin D3, K1, and geranylgeraniol, making the 180- and 60-capsule versions the only direct K2 choices here. The remaining formulas cover magnesium, B vitamins, zinc, homocysteine metabolism, and B12, giving you useful context for building a broader supplement routine without mistaking every item for a K2 source.

A Deeper Look At The Lineup
A magnesium routine feels simpler when the capsule count and elemental amount are easy to locate. This formula combines magnesium bisglycinate with magnesium oxide, giving you both chelated and non-chelated magnesium rather than relying on a single source. For a busy kitchen or a travel bag, the 120-count bottle is substantial, but the simple capsule format suits daily organization.
Chelation means magnesium is bound to an amino acid, which is the strategy used here for gentler digestion. Unlike the MK-4 products later in the lineup, this formula supplies no vitamin K2, so it belongs beside a K2 choice rather than in place of one. The honest read is that it works best for people prioritizing magnesium form and digestive comfort.
Points In Its Favor
- Two magnesium forms provide a more varied mineral profile.
- Each capsule supplies 150 mg of elemental magnesium.
- The chelated form is positioned for easier digestion.
- A 120-count supply suits established daily routines.
Practical Considerations
- This is a magnesium formula, not a vitamin K2 source.
- Combining the oxide and bisglycinate forms may feel less focused than a single-mineral capsule.
Key Product Details
Who It Suits Best
People seeking a straightforward magnesium capsule with two forms, 150 mg of elemental magnesium per serving, and an emphasis on digestive comfort.
A Better Fit Elsewhere
Designs for Health Vitamin D Supreme D3 + K2 180 Capsules better serves anyone whose primary goal is obtaining vitamin K2 in MK-4 form.
Looking for a K2 formula alongside vitamin D3 leads straight to this capsule, where the K2 is provided in MK-4 form. It also contains K1 and geranylgeraniol, abbreviated GG, a compound included to encourage the body’s natural K2 production. That makes the formula broader than a plain K2 capsule and more relevant to a D3 routine.
Compared with Designs for Health Magnesium Glycinate Complex, this product centers on fat-soluble vitamin pathways rather than mineral status. The 180-count bottle may be more practical for someone already using a daily D3 and K2 combination. Its complexity is the trade-off: you’re choosing a multi-nutrient formula rather than a single-purpose K2 option.
What Helps Most
- Provides the named K2 form MK-4.
- Combines K2 with vitamin D3 and K1.
- Adds GG to encourage natural K2 production.
- The 180-count bottle supports a longer capsule supply.
Worth Noting
- This is a multi-ingredient formula rather than K2 alone.
- Anyone using anticoagulant medication should ask a healthcare professional about vitamin K before adding it.

Made For
People seeking MK-4 vitamin K2 alongside vitamin D3, K1, and GG in a larger capsule supply.
Where Another Pick Shines
Designs for Health Vitamin D Supreme D3 + K2 60 Capsules offers the same named vitamin D and K features in a smaller bottle that takes up less space.
A smaller bottle can make a daily supplement easier to keep visible, and that is the main practical difference in this version. The listed formula still combines vitamin D3, K1, MK-4 vitamin K2, and geranylgeraniol. For a home office, carry-on bag, or compact cabinet, 60 capsules take up less room than the 180-count bottle.
Designs for Health Vitamin D Supreme D3 + K2 180 Capsules provides the same named vitamin features, so the choice is mainly about supply and storage rather than formulation. You may find the smaller count better for a shorter routine or a first trial, though the larger version may fit an established habit more conveniently.
Key Advantages
- Supplies K2 in the specific MK-4 form.
- Includes vitamin D3 and K1 alongside K2.
- Geranylgeraniol adds a distinct supporting ingredient.
- Compact 60-count bottle suits limited storage.
Small Caveats
- Fewer capsules may require more frequent replenishment than the 180-count version.
- It remains a combined D3 and K formula, not a standalone K2 capsule.
- Vitamin K warrants a medication review for people taking anticoagulants.
The Right Fit
People who want the listed D3, K1, MK-4, and GG features while favoring a smaller bottle for travel or compact storage.
Another Choice May Suit
Designs for Health Vitamin D Supreme D3 + K2 180 Capsules better fits an established routine that prioritizes fewer replenishment intervals.
A broad B vitamin capsule is useful when your goal covers several B vitamins rather than one isolated nutrient. This formula supplies all eight B vitamins, with most presented in coenzymated or methylated forms, meaning they are prepared in forms designed for easier use by the body. Quatrefolic folate provides the featured folate form, while B12, B1, niacin, riboflavin, B6, and biotin round out the blend.
Unlike the MK-4 choices, this product contains no listed vitamin K2 and should not fill that role. TMG and choline are included to support methylation, a chemical process involving the addition of a small carbon group to a molecule. The tradeoff is breadth, making it less convenient for someone who wants one clearly defined nutrient.
Useful Strengths
- Covers all eight B vitamins in one capsule.
- Uses coenzymated or methylated forms for most vitamins.
- Quatrefolic folate is included for bioavailability.
- TMG and choline provide a broader methylation-oriented blend.
- The formula is suitable for vegan and vegetarian-oriented routines.
Possible Compromises
- No vitamin K2 appears in the listed ingredient profile.
- A wide B vitamin blend offers less dosage precision than a single-nutrient capsule.
Core Details
Built With In Mind
People seeking broad B vitamin coverage in active-style forms, particularly those wanting one capsule instead of several separate B supplements.
Reach For A Different Pick
Designs for Health Vitamin D Supreme D3 + K2 60 Capsules better serves anyone whose priority is vitamin K2 rather than comprehensive B vitamin coverage.
Zinc routines often sit beside multivitamin or mineral formulas, and this capsule follows that broader pattern. It provides 30 mg of zinc bisglycinate, a chelated form in which zinc is attached to glycine. The formula also includes vitamins B6 and B2 plus chelated molybdenum, giving you a more involved nutrient profile than a plain zinc capsule.
Designs for Health Magnesium Glycinate Complex also uses chelation, but it places magnesium bisglycinate and oxide at the center instead of zinc. This zinc choice remains a separate goal from vitamin K2, with no K2 listed in its formula. It may suit a person who wants a chelated mineral with selected cofactors rather than a one-ingredient product.
Where It Helps
- Provides a stated 30 mg of zinc bisglycinate.
- Chelation makes the mineral form easier to identify.
- B6 and B2 complement the zinc-centered formula.
- Chelated molybdenum adds another mineral cofactor.
Things To Weigh
- This formula supplies no vitamin K2.
- Its 30 mg zinc amount is less adjustable than a lower-dose single-mineral capsule.
- People taking medications or managing a condition involving zinc should check with a healthcare professional before use.
Whose Shelf It Belongs On
People seeking 30 mg of chelated zinc with B6, B2, and chelated molybdenum in a focused mineral routine.
Not Your Match When
Designs for Health Vitamin D Supreme D3 + K2 180 Capsules better fits a routine centered on MK-4 vitamin K2 and vitamin D3.
Homocysteine Supreme is built around a specific biochemical pathway rather than a broad pantry of vitamins. Its modified B complex combines with L-serine and TMG, while methylated folate, methylated B12, P5P vitamin B6, and riboflavin round out the listed nutrients. The direction is clear: this is a focused formula for people already considering homocysteine metabolism.
Designs for Health Methylated Vitamin B Complex also emphasizes active-style B vitamins, but it covers all eight rather than concentrating on homocysteine-related nutrients. This specialized formula includes two capsules per day with meals, so your schedule needs to accommodate that serving pattern. It contains no K2, making it a separate choice from the MK-4 products.
Positive Takeaways
- Targets a specific homocysteine and methylation routine.
- Includes L-serine and TMG alongside modified B vitamins.
- Provides methylated folate and B12 plus P5P B6.
- Designed for vegetarian use without soy or gluten.
Details To Watch
- The listed use calls for two capsules daily with meals.
- Its narrow purpose makes it less useful as a general multivitamin.
- No vitamin K2 appears in the listed formula.
Feature Facts
Who Will Love This
People with a defined homocysteine-metabolism routine who want L-serine, TMG, and several modified B vitamins in one capsule.
Swap It Out When
Designs for Health Methylated Vitamin B Complex 120 Capsules better serves people who want broad B vitamin coverage rather than a homocysteine-focused formula.
Some routines are easier to maintain with a lozenge than with another capsule, and the berry flavor gives this B12 option a more approachable format. Each lozenge contains 5,000 mcg of methylcobalamin, the active form of B12, and dissolves slowly in the mouth. That makes the format practical for travel, a desk drawer, or anyone who routinely forgets a morning capsule.
The manufacturer designed the lozenge to deliver B12 through the oral mucosa, the moist lining of the mouth, rather than relying only on the stomach’s intrinsic-factor pathway. Unlike Designs for Health Vitamin D Supreme D3 + K2 60 Capsules, this item contains no vitamin K2, so it complements rather than replaces a D3 and K2 routine.
What Makes Sense
- Supplies 5,000 mcg of methylcobalamin per lozenge.
- The slow-dissolving format avoids another capsule with water.
- Berry flavor may make a daily routine more pleasant.
- Designed for delivery through the oral mucosa.
Less Ideal Details
- This is a B12 lozenge, not a vitamin K2 source.
- Lozenges occupy more space than a small capsule bottle and should remain in their packaging.
- The listed dose is a single-nutrient amount rather than a broad vitamin blend.
Quick Facts
Best Suited To
People who prefer berry-flavored methylcobalamin lozenges and want a simple daily B12 format outside the capsule category.
A Better Fit Elsewhere
Designs for Health Vitamin D Supreme D3 + K2 180 Capsules better fits anyone whose main requirement is MK-4 vitamin K2 with vitamin D3.
What To Look For In A K2 Supplement
Vitamin K2 is not interchangeable with K1, and “more K vitamins” on a label does not tell you which K2 form you’re getting. The two direct K2 choices in this roundup use MK-4, so the form is clear. You’ll also find vitamin D3 and K1 in both, which matters for anyone comparing a combined formula with a standalone nutrient.
Confirm The K2 Form
Start with the Supplement Facts panel rather than the front of the bottle. Look for “vitamin K2” and the specific form, such as MK-4, because different K2 forms are not automatically interchangeable. A larger capsule count adds convenience, but it does not increase the amount of K2 in each serving.
Check The Supporting Formula
The D3 and K2 products also contain K1 and geranylgeraniol. Geranylgeraniol is included to encourage natural K2 production, while D3 and K provide a broader combined routine. That makes these formulas more complex than a plain K2 capsule, so a clinician can help you compare them with the rest of your routine.
Match The Product To Your Goal
The other five formulas do not supply K2. Magnesium Glycinate Complex addresses magnesium form and digestive considerations, while the two B formulas focus on broader vitamin coverage. Zinc Supreme centers on chelated zinc, Homocysteine Supreme takes a more specialized approach, and the berry B12 lozenge favors a lozenge format. Choose based on the nutrient you actually want rather than treating the lineup as interchangeable.
Common Mistakes Worth Dodging
Mistakes Worth Dodging
A K2 label can distract you from the form, serving size, and companion nutrients. Check the Supplement Facts panel, compare the listed K2 form across products, and account for every capsule you already take. A larger bottle may last longer without making its formula stronger.
What Separates Premium From Basic
More elaborate K2 formulas may add vitamin D3, K1, geranylgeraniol, or a larger capsule supply. Those additions can suit a broader routine, but they also require closer attention to medication interactions and existing supplements. Paying for a more complex formula makes sense only when each added ingredient fits your plan.
Frequently Asked Questions For Form Of Vitamin K2
Which K2 Form Is Used In These Products?
The two Designs for Health Vitamin D Supreme choices use MK-4 as their vitamin K2 form. Both also include vitamin D3 and K1, with geranylgeraniol added to encourage natural K2 production.
Are All Seven Options Sources Of K2?
No, only the two Vitamin D Supreme options list vitamin K2. The other five are separate formulas centered on magnesium, B vitamins, zinc, homocysteine metabolism, or B12.
What Is The Difference Between The 180-Capsule And 60-Capsule Versions?
The listed vitamin D3, K1, MK-4, and geranylgeraniol features are the same. The 180-count bottle favors fewer replenishments, while the 60-count bottle takes up less storage space.
Is MK-4 The Only Form Of Vitamin K2?
No, MK-4 is only the form shown in this roundup’s two K2 products. K2 exists in other forms, so you should compare the exact form on each Supplement Facts panel rather than relying on the broader “K2” label.
Can Vitamin K2 Be Combined With Other Supplements?
That depends on your complete supplement routine and medications. Vitamin K can affect anticoagulant therapy, so ask your healthcare professional or pharmacist to check the combination before adding it.
Final Verdict
For vitamin K2 itself, the 180-capsule and 60-capsule Vitamin D Supreme options are the relevant choices because they identify MK-4 on the label. Pick the larger bottle for a longer supply or the smaller one for compact storage. The other products are separate nutrient formulas, useful for different priorities but not substitutes for K2.
