Understanding your Vitamin D results
Reference ranges used at Bangkok hospitals (nmol/L and ng/mL):
- ▸Severe deficiency: < 30 nmol/L (< 12 ng/mL) — medical treatment usually recommended
- ▸Deficiency: 30–49 nmol/L (12–19.9 ng/mL) — supplementation strongly advised
- ▸Insufficiency: 50–74 nmol/L (20–29.9 ng/mL) — most Bangkok doctors recommend supplementing to optimal
- ▸Optimal / sufficient: 75–150 nmol/L (30–60 ng/mL) — generally healthy range
- ▸Potential toxicity risk: > 250 nmol/L (> 100 ng/mL) — very high, usually only from excessive supplementation
- ▸Most labs in Bangkok report in ng/mL; to convert: multiply ng/mL × 2.5 = nmol/L
- ▸Bangkok target for most expats: many doctors here aim for 100–120 nmol/L (40–48 ng/mL) given high UV exposure expectations
- ▸Note: sun exposure in Bangkok is abundant but SPF use, indoor work, and pigmentation all reduce actual synthesis
Why expats in Thailand are often Vitamin D deficient
Surprising reasons Bangkok expats test low despite living in a tropical country:
- ▸Working indoors: office workers in Bangkok get almost no midday sun — glass blocks UV-B synthesis
- ▸Sunscreen use: SPF 30+ reduces Vitamin D synthesis by 95% — most health-conscious expats use high SPF daily
- ▸Avoiding peak-sun hours: expats often go out in the morning or evening, missing the 10am–3pm window when UV-B is sufficient for synthesis
- ▸Skin pigmentation: naturally darker skin requires significantly more sun exposure to produce the same Vitamin D as lighter skin
- ▸Covered clothing: some nationalities and religions wear covered clothing reducing skin exposure
- ▸Pool exposure only: swimming in covered or shaded pools doesn't help Vitamin D synthesis
- ▸Diet: Vitamin D from food (fatty fish, egg yolks, fortified dairy) is rarely sufficient alone
- ▸Baseline deficiency from home country: many visitors arrive already deficient from temperate climates
Treatment options in Bangkok
What Bangkok doctors typically prescribe for Vitamin D deficiency:
- ▸Mild insufficiency (50–74 nmol/L): Vitamin D3 supplement 1,000–2,000 IU/day — available OTC at Boots, Watson, most pharmacies (฿50–฿200/month)
- ▸Deficiency (30–49 nmol/L): typically 2,000–4,000 IU/day Vitamin D3, retest in 3 months
- ▸Severe deficiency (< 30 nmol/L): 5,000–10,000 IU loading dose may be prescribed; requires prescription in Thailand but easily obtained
- ▸D3 + K2 combination: many Bangkok hospitals recommend co-supplementation with Vitamin K2 (MK-7) to ensure calcium goes to bones not arteries
- ▸Brand examples available in Bangkok: D-Pearl (high dose), Nature Made D3, Healthy Origins D3 (at iHerb delivery or Lazada)
- ▸Megadose injections: available at Bangkok hospitals for severe cases — a single intramuscular injection of 300,000 IU — rarely necessary
- ▸Follow-up test: retest after 3 months of supplementation to confirm levels have normalised
- ▸OTC vs prescription: Vitamin D3 supplements up to 5,000 IU are generally available OTC in Thailand; higher doses and calcitriol (active form) require prescription
