Can You Take Creatine with Vitamin D3 and K2?

Creatine, vitamin D3 and vitamin K2 are unrelated compounds with no documented interaction. Creatine is involved in short-burst muscle energy; D3 and K2 are fat-soluble vitamins with their own separate roles. We don't sell a combined creatine-D3-K2 product, so if you're taking them as separate supplements, the only real question is making sure your total D3 and K2 intake across labels matches what each product actually directs.

Why these three end up mentioned together

Some multi-ingredient supplements, particularly gummies marketed to a general fitness audience, bundle creatine with vitamin D3 and vitamin K2 in one product. That's a formulation choice, not evidence that the three interact with or depend on each other. We don't sell a combined product like that — Electric Tiger Creatine Monohydrate's label lists one ingredient: creatine monohydrate, 5,000 mg per scoop, nothing else in the facts panel.

What each one actually is

Creatine is a small nitrogen-containing compound the body makes and stores mostly in skeletal muscle, where it's part of the energy system used for short, high-intensity effort. Vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone) are fat-soluble vitamins, meaning they're absorbed and stored differently than water-soluble nutrients like vitamin C. We don't sell a D3 or K2 product, so we're not making a specific claim about either one here — this page is about whether taking them alongside creatine causes a problem, not what D3 or K2 do on their own.

Is there a documented interaction?

We didn't find a trial testing creatine combined with vitamin D3 and K2 supplementation. Creatine's own safety literature, including the 2017 International Society of Sports Nutrition position stand, doesn't flag either vitamin as a specific concern, and nothing about D3 or K2's absorption pathway (dietary fat, not the phosphocreatine system) overlaps with how creatine works.

What to actually check if you take both

Since we don't sell a combined product, the practical question is dosing across two or more separate labels. Vitamin D3 and K2 supplements come in a wide range of doses, and taking more than one D3-containing product (a multivitamin plus a dedicated D3/K2 supplement, for example) can add up faster than expected. Read each label's own directions rather than assuming a "creatine gummy with D3 and K2" product's combined dose translates to taking three separate supplements at their own full doses.

Our creatine monohydrate

Electric Tiger Creatine Monohydrate is 5,000 mg of creatine monohydrate per scoop, nothing else in the tub, 50 servings, as low as $20.63 a bottle on subscription. It doesn't include vitamin D3, K2, or any other added ingredient.

Questions people ask

Can I take creatine with vitamin D3 and K2?

We didn't find a documented conflict between creatine and either vitamin. Each product's own label directions apply on their own.

Does creatine affect vitamin D or K2 absorption?

We didn't find a trial testing that specifically. D3 and K2 are absorbed through dietary fat, a separate pathway from creatine's phosphocreatine mechanism.

Do I need a creatine gummy with added D3 and K2?

That's a product-formulation question rather than a research one. If you want D3 or K2 at a specific, verifiable dose, a dedicated D3/K2 product with that amount printed on the label lets you confirm it directly, rather than relying on a combined gummy's total.
