The Blood Test That Made Me Take Vitamin D Seriously

I have been lifting three mornings a week since I turned 60, and I keep a spiral notebook with every set, every rep, and my bodyweight. So when my yearly checkup came back with a flag on my vitamin D, I did what I do with everything now: I asked my doctor what it meant, wrote it down, and gave the fix a fair eight-week test. The fix was one small softgel of Sports Research Vitamin D3 + K2 with breakfast, and the story of how that went is worth telling to anyone over 50 who lifts.

The number on the blood test was low enough that my doctor did not have to think twice. He said it plainly: my vitamin D was low, and for a man my age who was trying to hold onto strength, that was worth correcting. He recommended a D3 supplement and told me to take it with food, because it needs some fat to absorb. I had never paid much attention to vitamin D before that appointment. I figured I got plenty of sun walking a mail route for 31 years. Turns out the body does not bank it like that.

I did not want a complicated routine. I wanted one thing I could take with breakfast that would not fight me. The Sports Research softgel is tiny, which matters when you are in your sixties and do not like swallowing big pills. It is vegan, made with coconut oil, and I take one with my eggs and coffee. No taste, no burps, no fuss. I told Joanne I would give it eight weeks and then let the recheck decide.

Here is the honest part: I felt nothing day to day. No energy spike, no sudden bounce in my lifts. That is normal for a vitamin, and I said so in my notebook. What changed was the recheck a few months later. My doctor looked at the new number and said my vitamin D was back in a good range. That is the whole story, and for a supplement, that is the story you want.

I felt nothing day to day. What changed was the recheck: my doctor said my vitamin D was back in a good range. That is the story you want from a supplement.

Why does vitamin D matter for someone who lifts? The research language is careful, and I will keep it careful: vitamin D is linked to bone health, and it supports normal muscle function. For a 63-year-old who started lifting because carrying groceries up the porch steps got hard, that is enough reason to pay attention. I am not here to tell you it will add ten pounds to your bench. I am here to tell you what a blood test showed and what my doctor said.

The K2 part is why I picked this particular bottle. Vitamin K2 helps direct calcium where the body needs it, which is the kind of support that makes sense to me as a pair. I am not a biochemist, and I do not play one in my notebook. I read the label, I asked my doctor, and he was fine with it. One caveat he did mention: anyone on blood thinners should check with their doctor before adding vitamin K2. That is not a small footnote, so I am putting it here in the middle of the story.

I also want to be clear about what this supplement did not do. It did not fix my knees. It did not make me suddenly strong. The steady gains I have seen on leg press and seated rows came from showing up three mornings a week and finally eating enough protein, not from a softgel. The Sports Research D3 + K2 did one job: it helped bring a low number back into a good range. That is the whole honest deal.

Joanne started taking it too, same bottle, one softgel with breakfast. She does not lift, but she walks with me along the riverfront, and her doctor had mentioned vitamin D to her as well. It is nice when one simple thing works for both of us. The bottle sits in the kitchen cabinet beside the fridge, right next to the fish oil, so neither of us forgets.

What I'd Tell You If We Were Sitting at My Kitchen Table

If we were sitting at my kitchen table with coffee, here is what I would say. Get the blood test first. Do not guess. I would have sworn my vitamin D was fine, and the test said otherwise. Then, if your doctor agrees, pick a D3 supplement you will actually take every day. For me that was Sports Research, because the softgel is small, it goes down easy, and it does not repeat on me. Take it with food, give it a few months, and let a recheck tell you the truth.

And remember the order of things. Supplements come after food, sleep, and showing up to train. The Sports Research D3 + K2 is part of my morning routine, but it is not the reason I can get off the floor easier than I could at 60. That reason is the rec center, the notebook, and the protein shake. The softgel just makes sure my body has what it needs to do its part.
