How to Take Vitamin D3 and K2 With Sports Research Plantgels

You can buy the bottle in about a minute and then spend a month wondering whether you are taking it the right way. That was me in April 2024. I stood at the kitchen counter with a jar of Sports Research Vitamin D3 + K2 in one hand and my coffee in the other and realized I had no plan beyond what was printed on the front of the jar. So I did what I should have done before I ordered it. I wrote down every single thing I take, with the amounts and the times, and I carried that list to my pharmacist.

I am Lorna Ketterman. I am 57, I retired in June 2023 after twenty six years running a school cafeteria in Knoxville, Tennessee, and I am not a doctor, a nurse, or a dietitian. None of this is medical advice. It is the routine I have kept, written down the way I would explain it to a neighbor across my kitchen table. Before you add anything to what you already take, bring your full list to your own doctor or pharmacist, especially if you take prescription medication.

Step 1: Write the whole list down before you add a new bottle

My list has five lines. A multivitamin with breakfast, the Sports Research D3 + K2 with breakfast, a fish oil with breakfast, magnesium at nine at night, and a probiotic first thing in the morning with plain water. Five lines is not much, but it is more than I could keep straight in my head, and a couple of those lines overlap in ways that matter.

In January 2025 I took the list, printed out, to my pharmacist and asked her to look it over. She read it, asked a few questions about when I take each thing, and gave me one instruction: keep the magnesium apart from the morning group. That was the whole conversation. One change, and it was about timing, not about whether to take any of it. I take no prescription medication, so my list is simpler than a lot of people's will be, and that is exactly why I will not tell you what your list should look like.

The reason I bother with a list at all is that vitamin D hides in more places than people expect. My multivitamin carries some. The D3 + K2 plantgel carries more. If I were guessing, I would be guessing about a number I cannot see, and I would rather write it down and let somebody who knows more than I do read it back to me. Do that part before you open the jar, not after.

Step 2: Take one plantgel with breakfast, never on an empty stomach

Seven thirty in the morning is breakfast at my house, and that is when the plantgel goes down. One plantgel, with food, alongside the multivitamin and the fish oil. The listing calls them easy to swallow and I would agree, but the reason I take mine with a meal has less to do with the size and more to do with what is inside. The plantgels are made with coconut oil, and vitamins D and K are the kind of vitamins your body handles better when there is some fat in the meal. My breakfast almost always has some. Eggs, or toast with butter, or oatmeal with a spoon of peanut butter stirred in.

The other reason is that breakfast is the one meal I never skip. I worked a cafeteria line for twenty six years, so a morning without food feels wrong to me in a way an evening without food does not. If you are someone who skips breakfast and eats at noon, then noon with lunch is your version of this step. The point is not seven thirty. The point is picking a meal you genuinely eat every day and taking the plantgel with it, instead of swallowing it on the way out the door with nothing in your stomach.

One plantgel is the entire dose. According to the listing, each one delivers 125 mcg (5000 IU) of vegan D3 and 100 mcg of K2 as MK-7. That is enough that I do not take a second D on top of it, which is why step four matters as much as this one does.

Step 3: Park the jar where the routine already happens

My jar lives on the kitchen counter, about a foot from the coffee maker. Not in a cabinet, not in a drawer, not in a bag. The same spot every morning, next to the multivitamin bottle and behind the fish oil. When something lives where you already stand at seven in the morning, you stop having to remember it. You reach for it while the coffee is finishing.

It stays in its original container. I have never used a pill organizer, partly because I would forget to fill it, and partly because the original jar has the count and the amounts printed on it, which is the information I want in front of me when somebody asks what I take. The label is the record. I do not pour anything into an unmarked bottle and then try to recall what it was six weeks later.

This sounds like a small thing and it is not. A routine survives a busy week or a poor night of sleep only if it does not require decisions. Every decision is a chance to skip. If the jar is by the coffee maker and breakfast is at seven thirty, that decision was made in April 2024 and I have not had to make it again.

Step 4: Read your other labels so you are not stacking the same vitamin twice

Vitamin D is not only in a D supplement. My multivitamin carries some, and it took me one reading of two labels to understand that I was adding to a number rather than starting from zero. That is not a reason to panic. It is a reason to read the back of every bottle on your counter once, write the amounts on the same sheet of paper, and keep that sheet where you keep the bottles.

Here is the part I want to be careful about. I am not going to tell you what total is right for you, and I am not going to tell you what to do if the numbers add up to more than you expected. I brought my list to my pharmacist and asked her to look it over. She read it, we talked about timing, and the one instruction I came home with was about keeping the magnesium apart from the morning group. I did not ask her to bless a number, and even if I had, that answer would be about me and not about you. That conversation belongs between you, your own doctor, and your own pharmacist.

What I can tell you is what one plantgel of Sports Research D3 + K2 carries, because it is printed on the listing: 125 mcg, or 5000 IU, of D3 from lichen, and 100 mcg of K2 as MK-7. If your multivitamin or your calcium supplement already has D in it, that belongs on the list before you add this jar to the rotation.

Step 5: Plan the reorder before the jar runs out

Thirty plantgels, one a day, is about thirty days. That is the deal, and it is the only real annoyance of this product. A thirty count jar means the bottle is a monthly item, not a twice a year item, and a monthly item will sneak up on you if you are not paying attention.

My system is simple. I pick the jar up every Sunday, and when it feels light I order the next one. I buy it myself on Amazon, the same way I bought every other bottle on that counter. Nobody sends me anything. I have not run out yet and I would like to keep it that way, because the routine is easier to keep when there is no gap in it.

If you take more than one thing, put all the reorders on the same weekly check instead of on your memory. Three bottles running out in the same week is a thing that happens, and the fix costs about a minute on a Sunday morning.

What Else Helps

Food first, then the bottle. I am not going to pretend a plantgel replaces anything on your plate. I eat fish about once a month, which is why there is a fish oil on my counter. I spend most of the winter indoors, which is why there is a D on my counter. Those are gaps, and a supplement is a way to fill a gap, not a way to skip the meal.

Keep the evening separate. My magnesium is the only thing I take at night, and my pharmacist's one instruction was to keep it apart from the morning group. Nine o'clock, on the nightstand, after the kitchen is closed for the day. Whatever your version of that looks like, the principle is the same. Group the things that go together and do not let the groups blur into one long handful.

Expect boring. That is the honest report. I have taken this plantgel with breakfast since April 2024 and there has been no dramatic change, no morning where I felt different, no story worth telling at the table. I take it because I would rather fill a gap in a normal diet than wonder about it, and because the routine is easy enough that I have not quit. If you are looking for a feeling, this is the wrong shelf to be standing in front of. If you are looking for a simple habit with a label you can read for yourself, it is a reasonable one, and your own doctor or pharmacist can tell you whether it fits with everything else you take.

One plantgel at 7:30 in the morning, 125 mcg of D3 and 100 mcg of K2 as MK-7, taken with a meal that has some fat in it. That is the entire method, and I have not missed a stretch of days since April 2024.
