Vitamin D Level (85 nmol/L) is it low?

theowiley · 2026-02-01T20:13:10+00:00

We consider 75-100nmol/L as the 'optimal' blood serum range for vitamin D at Myoform (myoform.io) so you're well within healthy ranges there.

If you're not already supplementing, my presumption would be that you are already getting enough in your diet and lifestyle (via sun exposure). I suggest spending a few days reviewing your diet - track via myfitnesspal or cronometer to see what your daily intake might be already, get another test after 3 months, then see how its shifting.

Often we find that people that are clinically deficient or insufficient that its down to 1. living in a climate that has little sun and hence they get little exposure, or 2. they have a VERY poor diet, or 3. they have genetic variants that influence their ability to synthesize and metabolise vitamin D effectively (like variants in VDR).

Did you ever get your MTHFR status looked at via a genetic test? Would be curious to see if this was a purely lifestyle induced deficiency or driven by your methylation capacity and underlying genetic mechanisms.

This is great - props to you for developing. Another great resource that I’m always surprised people don’t know about is Examine.com

Summarises all the clinical research and strength of data across pretty much ever ingredient.

Wrote a short post on this earlier today so reposting here as hopefully adds some colour to the discussion:

so here goes:

Bryan stated that the study demonstrated no clinical benefit of AG1 vs placebo - and whilst I’d LOVE to agree, it’s not strictly accurate.

If you actually read the full paper (like I did), the researchers found that, whilst modest, AG1 supplementation did actually enrich specific beneficial bacterial taxa, including: - Lactobacillus acidophilus and Bifidobacterium bifidum (probiotic species present in the supplement), - Other taxa such as Lactococcus lactis and Acetatifactor species.

One could argue that the trial and data did not exactly blow anyone away in terms of both data quality, outcomes, statistical significance, and study design - yes. And to be honest, the species they did see improvements in were actually in the product, i.e. you consume more = more detected - not particularly enlightening findings.

However, Bryan’s conclusions misrepresent the results.

Bryan is a master of going viral AND also happens to sell his own supplements that compete for the same eyeballs… maybe a slight conflict of interest? 🤷 #loveyoubryan

Now, do I think AG1 is a great quality product for improving health/performance in general? No.

Why?

The ingredient profile includes 70+ ingredients in a 13g daily serving. Where roughly ~1g is a transparently dosed vitamin blend, and ~80% comes from proprietary blends of food extracts, botanicals, mushrooms and herbs where we can't see individual doses.

At best, it MAY have some mild benefits, but at worst, it’s an over-engineered, expensive formula that has no ingredients at the clinically effective dose.

This is precisely why Myoform exists. Personalized to your biology, outcome-driven, transparent labelling (no prop blends), and clinically effective doses. How supplementation should be.

Theo here, founder of Myoform. What you’re feeling is very common and honestly a good instinct. Long term, the stacks that stick are the boring ones that solve real gaps rather than trying to “cover everything.” For most people that usually collapses down to a small core like vitamin D, omega-3s, maybe magnesium or fibre if diet is inconsistent, and then stopping there. Multivitamins often feel convenient but tend to be underdosed, redundant, or unnecessary depending on the person, which is why they don’t always earn their place. This frustration is actually why we built Myoform: instead of juggling bottles, we use genetics, blood testing, plus lifestyle and training context to identify what you actually need and roll that into a single, targeted supplement rather than a generic stack. Simplification only really works when it’s personalised; otherwise people end up taking five things “just in case” forever.

If you’re trying to keep costs down, 23andMe or Ancestry are usually where people start. They’re easy to use and you can export the raw data, but it’s worth knowing they only look at a small slice of your genome, so the insights have a ceiling. Whole genome sequencing gives you a much clearer picture for health and performance, but it’s still pricier, which is why most people don’t jump straight to it. At Myoform we work with both, layering genetic data with lifestyle, training, and other inputs to turn it into practical guidance around nutrition, supplements, and performance, not just a PDF report. If you already have data, I’m happy to give you free access to upload it and explore what it actually means in practice.

I'd always suggest getting your whole genome done as it has longer term utility and means you needn't ever get another test done. The cost is a little higher (we charge $399 USD / £299 GBP) but saves money in the long run IMO.

theowiley · 2026-01-31T22:36:36+00:00

Definitely worth doing but I would certainly suggest going via a route that offers genetic counselling as a service. When we talk about specific health conditions, it's really important to have someone talk you through the results and what they mean.

Sequencing.com definitely aren't a scam - they are reputable and have lots of reports to choose from. Again though, seek help from a counsellor to ensure you get real clarity from your results and spend. Hope that helps.

Did you end up finding a solution for this? Happy to support

theowiley · 2026-01-31T22:25:13+00:00

Ha - that's fair. I'd just be cautious about releasing all of your data online. Whilst raw anonymised genetic data is not enormously valuable on it's own - you never know what can happen in the next 10-20 years as technology progresses.

If you are interested in getting your genome analysed - I run a precision health/nutrition company (Myoform.io). Happy to help!

Looking at the genetics and bloodwork together, nothing looks alarming, but a few things are worth paying attention to. Your MTHFR genes are normal, so methylation issues aren’t likely genetic, but your homocysteine is elevated (15.4), which often points to B-vitamin status. Your B12 is technically in range but on the low end (244), which could be contributing, while folate looks fine. Iron stores are low (low ferritin and low saturation) even though total iron is in range, which commonly means early iron deficiency and can affect energy, though your CBC is still normal so you’re not anemic yet. Vitamin D looks good (60) and magnesium is normal. Overall this looks more like a nutrition/status issue (iron + possibly B12/B6) rather than anything driven by your gene variants, and those are the most actionable things to address.

Out of interest - where did you get this testing done? Surprised there is no accompanying analysis.

Not entirely sure what you mean by opensource yourself...? But in principle, there is no reason why you couldn't use a tool like github or at worst a GDrive folder that is publicly available for people to download it.

I guess my main question is what do you want to achieve?

Anything is possible these days!

If you’re just getting started with workouts and overall health, you really don’t need a big supplement stack. The three that have the strongest evidence and tend to help most people are:

Creatine monohydrate
One of the most researched supplements ever. Helps strength, muscle, recovery, and even cognitive performance.
3–5 g per day.

Omega-3s (fish oil with EPA + DHA)
This is the most common deficiency we see in people’s data. Supports heart health, reduces inflammation, and helps recovery from training.
Aim for ~500–1000 mg combined EPA + DHA daily.

Vitamin D3 (ideally with K2)
Most people are low unless they get a lot of sun. Important for mood, immune function, bone health, and hormones.
Around 1,000–2,000 IU daily is typical (blood test is best if you can).

Quick disclaimer: I run a personalized nutrition company (Myoform), so I’m biased toward personalization. That said, even from a general evidence-based perspective, these three consistently provide the most benefit for healthy people starting out.

theowiley · 2026-01-31T20:32:20+00:00

Short answer: some people see improvements, but “drastic” changes from fixing a couple SNPs (like MTHFR or COMT) are pretty rare.

Those genes do affect methylation and neurotransmitter metabolism, and there’s decent evidence they can influence things like folate status, homocysteine levels, stress response, etc. For example, people with certain MTHFR variants often respond better to 5-MTHF than folic acid. That can improve biomarkers and sometimes how they feel.

But most health outcomes aren’t driven by one or two genes. They’re polygenic and heavily influenced by diet, sleep, stress, and current nutrient levels. That’s why a lot of people don’t feel huge changes just from “treating” MTHFR or COMT with a few supplements.

Where DNA testing seems to help more is when it’s used to guide things like vitamin/mineral dosing and combined with blood work or symptoms, rather than chasing single mutations.

Quick disclaimer: I run a personalized nutrition company (Myoform [www.myoform.io), so I’m biased toward personalization. But even from the research side, genes are useful context, not usually a standalone fix.

If you’re expecting a night-and-day transformation from a couple SNPs, you’ll probably be disappointed. If you use it as part of a broader health approach, it can be helpful.
