Know Your Numbers - Part 2
A few weeks ago, I went for my
Birthday Blood Test, purely for preventative measures. Last year was my first so I wanted to see if any of the measures I put in place had made a difference. This time it took 2 weeks to get the results then a few days pouring over, translating results.
I had a few extra tests this time around including one for Magnesium, as I have been taking this for years but didn't know what my levels were.
On the whole, my results were good and virtually all improved.
So here's some of the results and what supplements I take and whether it's worth it.
Magnesium - I have been taking Magnesium Oil spray for many years. I take the spray (added to skin) as it bypasses the digestive system, going straight into blood stream (Oral Magnesium can produce digestive issues and also if you have current digestive issues, it can affect absorption). My levels are at the higher range of what's needed. So i'll keep taking the supplement.
Vitamin D3 - last year, my levels were at 'insufficient', so this year I have spent more time in the sun, sensibly, without sunscreen (haven't used sunscreen for almost 20 years). This year my levels have increased substantially but still room for improvement. Therefore, I'll try and get more safe sun exposure.
Creatine - I have only started taking this supplement the last few months. I took it many years ago when I stopped running and began in the gym but didn't find it did much for me. The last year or so, a lot of research has concluded that Creatine is not just for muscle growth, but more importantly for brain health and cognition, and this is why I take 10mg instead of the old thinking of 5mg per day. This year, my results show a significant improvement in levels, so i'll keep taking it. So that proves i'm getting more intelligent with age... 😏
Testosterone - No supplements taken for this. There are 2 readings for this. Total and Free. Last year my levels were midway for Total, and below sufficient for Free. This year, my Total level has improved and is in the upper range, and my Free levels have improved to almost mid range. I put this down to more resistance training (sporadic), fasting and losing weight/bodyfat. Room for improvement and this will be down to more consistent training.
B Vitamins - I started taking a Methylated B Complex supplement last year after a DNA test suggested I couldn't absorb 'normal' B vitamins. Methylated means it is in 'pre-absorbed form' so the body doesn't have to process it.
B9 (Folic Acid) - this year my levels have doubled and are at the higher range
B12 (Cobalamin) - Last year my levels were at the lower range suggesting supplementation is required. This year my levels went DOWN (even with supplements) and are at the lowest range. For this reason, i'm going to change the supplementation and get a re-test in a few months.
Vitamin A - I didn't get this result last year and I don't take anything specifically for this, apart from normal diet. This year my result was practically top of the range level, so no need to add supplements but keep with diet.
All Liver and Kidney levels were good AND improved, so no need to reduce anything in diet 😏
ALL Red Blood Cell tests were good.
All White Blood Cell tests were good, apart from one. My Monocytes % was high (increased over last year) but this can happen when Vitamin B12 is low, so that makes sense - need to sort B12 and re-test. Saying that, my Monocytes Absolute Value, which is more important, is at higher range, so all good.
Blood Glucose levels - last year was just within range but this year it had gone over accepted range. This didn't make sense as we do not consume sugar (apart from alcohol), and very limited processed foods, virtually no bread. I have a Blood Glucose and Ketone test kit at home and it has tested good and lower than last year. I'll check a bit more regularly but don't see it as an issue.
Now, the only thing of concern was the PSA (Prostate). Again, you have a Total range and a Free range. Both of mine have increased significantly over last year but...
You divide the Free result by Total result and get a %, and my % is well within range - should be above 25% and mine is 31% . Therefore, i'll go and get another test in a few months.
Phew, a long post and you may ask why or what's the point? It's a numbers game. Knowing the metrics of your health can kick-start you into making improvements in your health and fitness regimes.
I know I don't have to waste money on certain supplements as my diet is covering that. I can change certain supplements to see if that improves certain things. If I feel some improvements are down to diet - adding/removing certain things, exercise, then the test results back those up...
