How to Tell Whether a Supplement Is Doing Anything
Share
Most people genuinely cannot answer this about anything they take. Not because nothing changed, but because they never wrote down where they started — and memory is a poor instrument for comparing how you felt eight weeks ago to how you feel now.
The baseline problem
Human recall of past internal states is unreliable in a specific direction: current state colours the memory of past state. Feeling good today makes last month feel worse than it was. Feeling flat today does the reverse.
This is why every clinical trial takes baseline measurements before the intervention starts. It isn't bureaucracy. Without a baseline there is nothing to compare against, and the comparison you make from memory is systematically distorted.
What to record before you start
Keep it to three or four things you can score quickly. More than that and you'll stop after a week.
- Energy through the day — 1 to 10, recorded at the same time daily
- Sleep quality — 1 to 10 on waking, not sleep duration
- One thing specific to you — whatever prompted you to look into this in the first place
Score them for a full week before you change anything. That week is your baseline.
Then leave it alone
The biggest error after starting is changing something else. New supplement, new training routine, new sleep schedule, all in the same fortnight — and now nothing is attributable to anything.
Change one variable. Give it the full window. Then decide.
Why eight weeks
Nutrient status doesn't shift on a weekly timescale. Red blood cells turn over roughly every four months, and intervention studies on folate and B12 status generally run eight to twelve weeks minimum for that reason.
Assessing at two weeks measures expectation, not status.
On bloodwork
If you're having levels checked, test before you start and after at least eight weeks, at a similar time of day, ideally through the same lab. A single post-intervention result with nothing to compare it to tells you very little.
What the nutrients contribute
Folate, vitamin B12 and vitamin B6 each contribute to normal homocysteine metabolism. Folate and B12 contribute to the reduction of tiredness and fatigue and to normal blood formation. B12 contributes to the normal function of the nervous system.
Sized to the window
Our 2 Tub Bundle is two months' supply. That's the minimum window over which any assessment is meaningful, in one order, without a gap in the middle where you ran out and waited for delivery.
Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Do not exceed the stated dose.
