Step 1: Natal Conditions, Vitamin D Deficiency, and IQ Impact by Race
We’ll assess maternal conditions (maternal mortality, low birth weight, premature birth, pre-eclampsia) linked to vitamin D deficiency, estimate their prevalence by race, attribute a portion to vitamin D, and calculate potential IQ impacts. Data on vitamin D’s role in these conditions is mixed—some meta-analyses show associations, others don’t—so I’ll use conservative, plausible ranges.
Maternal Conditions and Vitamin D Deficiency by Race
Prevalence Data: US-centric (CDC, NIH), adjusted for global trends where applicable.
Vitamin D Deficiency: Defined as 25(OH)D < 20 ng/mL. Prevalence varies by race due to skin pigmentation, diet, and latitude.
Black: 70-80% (US studies, e.g., NHANES).
White: 20-30%.
Hispanic: 50-60%.
Asian: 40-50% (varies by region, e.g., higher in South Asia).
IQ Impact: Studies (e.g., Melough 2020, CANDLE cohort) suggest 2-4 IQ points per 10 ng/mL increase in maternal 25(OH)D. I’ll use 2-3 points as a conservative effect size.
Maternal Death in Childbirth
Prevalence (per 100,000 births, US 2021):
Black: 69.9
White: 19.1
Hispanic: 28.0
Asian: 13.8
Vitamin D Link: Weak direct evidence—pre-eclampsia (vitamin D-related) contributes ~10-15% of maternal deaths. Assume 10% of deaths tied to vitamin D deficiency (speculative, based on hypertension overlap).
Attribution: 10% of prevalence.
IQ Impact: Surviving offspring may face neglect or stress, costing ~1-2 IQ points (Guatemala study proxy). Population effect = prevalence × attribution × IQ loss.
Black: 69.9 × 0.1 × 0.001 × 1.5 = 0.01 IQ points.
White: 19.1 × 0.1 × 0.001 × 1.5 = 0.003.
Hispanic: 28.0 × 0.1 × 0.001 × 1.5 = 0.004.
Asian: 13.8 × 0.1 × 0.001 × 1.5 = 0.002.
Low Birth Weight (LBW, <2500g)
Prevalence (%):
Black: 14.2
White: 7.0
Hispanic: 7.5
Asian: 8.3
Vitamin D Link: Meta-analyses (e.g., Qin 2016) show 25-50% higher LBW risk with deficiency. Assume 30% attributable.
IQ Impact: LBW linked to 3-6 IQ point loss (Guatemala study). Use 4 points.
Black: 14.2 × 0.3 × 0.04 = 0.17 IQ points.
White: 7.0 × 0.3 × 0.04 = 0.08.
Hispanic: 7.5 × 0.3 × 0.04 = 0.09.
Asian: 8.3 × 0.3 × 0.04 = 0.10.
Premature Birth (<37 weeks)
Prevalence (%):
Black: 14.4
White: 9.3
Hispanic: 10.0
Asian: 8.8
Vitamin D Link: Trials (e.g., Hollis 2011) suggest 20-40% reduction with supplementation. Assume 25% attributable.
IQ Impact: Preterm birth costs 5-10 IQ points (Guatemala, Jamaica studies). Use 6 points.
Black: 14.4 × 0.25 × 0.06 = 0.22.
White: 9.3 × 0.25 × 0.06 = 0.14.
Hispanic: 10.0 × 0.25 × 0.06 = 0.15.
Asian: 8.8 × 0.25 × 0.06 = 0.13.
Pre-eclampsia
Prevalence (%):
Black: 5-7
White: 3-4
Hispanic: 3-5
Asian: 2-4
Vitamin D Link: 30-50% higher risk with deficiency (Wei 2013 meta-analysis). Assume 40%.
IQ Impact: Associated with preterm/LBW, indirect effect ~2-4 points. Use 3 points.
Step 2: Genetic Differences in IQ and Vitamin D Contribution
Polygenic GWAS for IQ/Education
Observed Gaps: From GWAS (e.g., Lee 2018, Savage 2018):
White-Black: 10-15 IQ points (1 SD).
White-Asian: 0-5 points (Asian advantage).
White-Hispanic: 5-10 points.
Genetic Share: Polygenic scores explain 10-20% of IQ variance (3-5 points of gaps). Assume 12 points (White-Black), 3 points (White-Asian), 8 points (White-Hispanic).
Vitamin D Genetic Factors
Positive (Efficient Metabolism):
GC Gene (rs2298850): Enhances vitamin D binding/transport. Higher frequency in Europeans (70%) and Asians (60%) vs. Africans (~30%). May boost 25(OH)D by 2-5 ng/mL, adding ~0.5-1 IQ point.
CYP2R1: Vitamin D activation. Similar racial distribution, small effect (~0.5 points).
Negative (Sugar Metabolism):
High sugar intake depletes vitamin D (speculative, via inflammation/insulin). No clear GWAS link, but African/Hispanic diets higher in sugar (NHANES) might amplify deficiency by 10-20% (~0.5-1 point loss).
Genetic (Step 2): 6-33% of gaps (Black-White: ~2 points, ~17%).
Environmental: Bulk of gain (3-6 points) from deficiency correction—80-90% of total.
Synthesis and Implications
Total IQ Impact: Vitamin D explains ~1-2 points of genetic IQ gaps (17% Black-White, less elsewhere), dwarfed by environmental factors (5-8 points max gain).
2.5°C Plan Fit: Boosting IQ via nutrition aligns with alien green growth—AD/nuclear powers supplementation infrastructure.
Novel Hook: Black-White gap narrows by ~5-10 points with universal intervention—social tension as geneticists debate residual differences.
Resources
Melough 2020 (CANDLE study), Qin 2016 (LBW meta-analysis), Wei 2013 (pre-eclampsia), Guatemala study (protein-energy gains), Lee 2018 (GWAS).
Gaps: Direct vitamin D-IQ causation weak; sugar link speculative—needs more research.
What’s your next angle—refine a condition, tweak genetics, or plot twist?
I’m a bit disappointed that this approach doesn’t eliminate more of the 3 to 5 points attributable to genetic factors, but it’s a start. That being said, it’s hugely positive that a combination of vitamin D supplementation and managing sugar intake for children could help reduce a substantial amount of the remaining racial IQ gap. And hey- a 1.5 to 3 point IQ boost for white people would also have positive impacts. I’ve been working on a concept for a sci fi novel for some time- ignore that bit.
Addendum: I asked Grok to expand my search for genetic factors which might lead to differences in IQ. One possible culprit is Omega-3, vital for cognitive development. I quote: FADS gene polymorphisms affect DHA conversion from ALA. African ancestry groups have lower synthesis efficiency (lower DHA blood levels), while East Asians (marine-adapted) and Whites show higher efficiency. An Omega-3 strategy for kids could lead to a 1 to 2 IQ point increase for whites, a 3 to 5 point increase for Blacks, and a 0 to 1 point increase for East Asians. Protein also seems to be a factor, as generally human genetics prioritises physicality before cognitive development, and groups which have been historically sedentary for longer may enjoy a dietary developmental advantage as a result. A protein strategy for Black kids could raise IQ by 2 to 4 points, compared to 0 to 1 point for other groups. Again, it’s a case of societal embarrassment and stigma related to discussing controversial topics preventing the genuine reduction of racial disparities.
It’s also worth noting that throughout this exercise I’ve found that lower SES backgrounds and Western cultural convention, built up over generations by social class and group, seem predisposed to penalise groups which have existing genetic vulnerabilities, which compound the negative IQ effects of genetic factors.
For example:
White Children:
Current State: Typically meet or exceed needs (1.0–1.2 g/kg/day).
Strategy: Maintain current levels, emphasizing quality (e.g., replacing processed meats with lean options).
IQ Benefit: Minimal (0–1 point), as deficits are rare.
Mechanism: Ensures no marginal loss; supports baseline cognition.
Black Children:
Current State: Often 0.8–1.0 g/kg/day, with lower-quality sources (e.g., processed foods).
Strategy: Increase to 1.5 g/kg/day via affordable sources (e.g., eggs, fortified milk), targeting low-SES areas.
IQ Benefit: 2–4 points, as protein shifts from muscle/immune priority to brain growth.
Current State: High intake (1.2–1.5 g/kg/day), often fish-based.
Strategy: Sustain current levels, integrating omega-3-rich proteins (e.g., salmon).
IQ Benefit: 0–1 point, as needs are largely met.
Mechanism: Reinforces existing cognitive advantage via synergistic DHA-protein effects.
How It Helps
Universal: Adequate protein ensures amino acid availability for dopamine and serotonin, critical for learning and memory.
Race-Specific: Blacks benefit most due to higher baseline deficits and potential muscle prioritization, closing gaps by redirecting resources. Whites and East Asians see smaller gains, as their protein needs are already met.

It is frustrating that poverty correlates to lower IQ, not race and not racism, but too many objections from programmed ignorant, Ideologs and those that profit from the false "it's because of racism". It's like offensive 'Hecklers Veto' and those that might benefit from hearing this do not get a chance because some retarded spastic virtue-grasping cnt attacks me for racism when a good slap loving correction and explain that she is too stupid to vomit-out her unJust viciousness, Ideologs will argue everything from IQ is not science, IQ is only educations and environment, or any child of any race if raised the same will be the same in IQ, ability to learn, same impulse control, same response to frustration, propensity for violence, same delayed gratification abilities ".. so, you're a racist and I am Mother protector of all races except white males - they should die early,", those profiters of division, race-hate, ignorance, .., and likely know your information but acts for others that only ignorant racist white men would try to harm them sad minorities that you stole from, otherwise they would be rich.
The first women should be slapped until silent or thrown out the meeting, the ideolog required reprogramming, tied to a pole with collar around neck, and correct information projecting on screen and questions asked about material. Wrong answers cause Taser-shock through neck-collar. Must stop if she soils herself and start over next day.
A white man with IQ of 80 will struggle in poverty similar to a black man with IQ of 80.
Military will not allow men with 83 or lower IQ to join, yet we turn them out on streets to suffer and die on those feces covered sidewalks.
So, those that blame racism would sentence the blacks to resentful hate filled failure, and whites to anger and violence from blacks that believed those evil, ignorant, brain-washed people, and many would rather endless suffering and deaths of those victims, then re-calibrate their thinking and consider other possible solutions then kicking white men's testicles screaming 'Racist!' - you vicious mind-raped man-hating delusional psycho Feminist.
It's also true that whilst they moaned and wailed about structural racism causing higher rates of death from COVID, Black people had the most to gain from vitamin D supplementation, given that 90% were D deficient. Hundreds of thousands could have been saved by cheap pills obtainable over the counter from any pharmacist- not to mention the millions of others. Why? Because they wanted to push the most profitable vaccine in human history.
Caucasians absorb vitamin D from the sun more easily and black people absorb it the least easily because skin color makes a big difference. So yeah, supplementation is going to be more important for those with darker skin.
You can't use "low birth weight" as an exogenous variable. This is a sociologist fallacy. By hereditarianism, birth weights are expected to differ by race for genetic reasons, and these norms are based on Europeans, and so are the preterm birth statistics. Africans have faster life history, so they gestate slightly faster than Europeans and have slightly smaller babies at birth.
By the way, you can also throw in lead poisoning, and it will also account for <1 IQ using the same approach. Maybe Grok can figure out the math for that one too.
I see your point. Mine was that despite the fact that these environmental factors were uniform across groups, the fact that some groups are genetically more prone to some conditions than other groups, means that the effect on IQ is stronger for some than for others- by applying a uniform correction across all groups, it's effectively closing the IQ gap-although admittedly this part of my meanderings was relatively minor.
The far more interesting results were for vitamin D supplementations effect on childhood development. Ditto with Omega-3 and protein intake, as well as sugar as a negative factor. Here we have known genetic factors within ancestor groups, and strong effects from diets and/or supplementation effectively correcting for genetic disadvantages in relation to IQ. But you're right, it was a mistake to focus on maternity. It's all about some groups being better genetically equipped to optimise intakes towards cognitive development as the organism grows- although supplementation is likely a good thing for foetal development.
It's worth noting that the protein optimisation for physicality is two factors not one, which breaks down into sprint capacity for West Africans and endurance running for East Africans. Regardless, Grok speculated that doubling the protein intake for African groups would have a 2 to 4 point effect, as opposed to a relatively minor effect for whites, and a negligible effect for East Asians. I have to admit protein intake blindsided me. I was focused on the known areas where very specific deficiencies can have known effects.
Regardless, I think I've shown that an emphasis on specific dietary and supplementary intakes will improve IQ, and that this effect will likely be stronger for some groups than for others, effectively correcting for significant amounts of the polygenic differences between groups in relation to IQ. I know it seems counterintuitive to argue environment can correct for genetics, but the genetic differences in IQ seem to be specifically related to how the organism optimises diet for cognitive development, and whether other attributes like physicality are given priority over cognitive development.
It's worth noting lighter skin and possibly fair hair evolved in humans adapting to vitamin D-poor latitudes, aiding overall health- including women’s ability to carry pregnancies to term- though multiple pressures shaped these traits. In other word, depigmentation probably occurred specifically because of the vitamin D issue.
20 ng/mL, is just what the kidneys require in order to perform their role in regulating calcium-phosphate-bone metabolism.
The immune system needs 50 ng/mL (125 nmol/L = 1 part in 20,000,000 by mass) circulating 25-hydroxyvitamin D in order to function properly - as can be seen in this analysis of post-operative infections according to pre-operative 25-hydroxyvitamin D levels at Massachusetts General Hospital: https://jamanetwork.com/ journals/jamasurgery/fullarticle/1782085. Please see Figures 1 and 2 in the PDF, which do not appear in the web version of the article.
50 ng/mL is 2.5 times the level governments and many doctors consider adequate for good health - but this lower level, Most people with modest vitamin D3 supplementation (1000 IU or less a day, as recommended by governments and many doctors) and/or a little ultraviolet B exposure of ideally white skin have levels around 20 ng/mL. Many people have less than this - and some, especially the elderly and those with black or brown skin, have as little as 5 ng/mL
There's very little vitamin D in food, including that which is fortified with vitamin D3 or the less effective D2. Far from the equator, UV-B in sufficient quantities to appreciably raise 25-hydroxyvitamin D levels is only available in the middle of cloud-free summer days, without glass, clothing or sunscreen intervening.
Please also see the research on vitamin D and the immune system cited and discussed at: https:// vitamindstopscovid.info/00-evi/. This includes recommendations for how much vitamin D3 to supplement, from New Jersey based Professor of Medicine, Sunil Wimalawansa, as ratios of body weight with higher ratios for those suffering from obesity. For 70 kg (154 lb) without obesity, 0.125 milligrams (5000 IU) a day is a good amount. This is a gram every 22 years, and pharma grade vitamin D3 costs about USD$2.50 a gram ex-factory.
