Low magnesium is linked to insulin resistance
Why it may be relevant
You want to uncover any nutrient gap working against you, and magnesium plays a direct role in blood-sugar regulation.
Low magnesium is commonly linked to insulin resistance, so identifying and correcting a shortfall may support better glucose control.
Dose or use Ask your healthcare practitioner about testing and whether more magnesium-rich foods would help.
Key study Correcting a documented shortfall can support recovery; this is a root-cause check, not a treatment claim — ask your provider about your levels.

Pressure point
ST36 (Zusanli)
Evidence grade not assigned · Traditional use long-standing
Traditional acupressure point for metabolism
Why it may be relevant
You're interested in traditional practices, and ST36 (Zusanli) is a key acupressure point long used in Chinese medicine for digestive and metabolic support.
In traditional Chinese medicine, ST36 is used to support the spleen–stomach system and overall vitality; this is a traditional practice, not a clinically proven blood-sugar treatment.
Dose or use Apply firm, steady pressure to the point below the knee for 1–2 minutes on each leg, once or twice daily.
Key study Traditionally used in Chinese medicine for metabolic and digestive support; this specific use has not been confirmed in controlled clinical trials.

Nutrient gap worth checking
Vitamin D Deficiency
Evidence grade not assigned · Traditional use long-standing
Low Vitamin D is common and worth checking
Why it may be relevant
You want to identify any underlying gaps, and Vitamin D deficiency is widespread and has been linked to glycemic outcomes in research.
If you're low in Vitamin D, correcting it may support better blood sugar regulation based on clinical research in prediabetes populations.
Dose or use Ask your healthcare practitioner for a 25-OH Vitamin D blood test.
Key study Correcting a documented shortfall can support recovery; this is a root-cause check, not a treatment claim — ask your provider to test your levels.

Chromium Deficiency
Evidence grade not assigned · Traditional use long-standing
Chromium supports insulin action
Why it may be relevant
You want to know whether a nutrient gap is driving your blood sugar, and chromium is central to how your body uses insulin.
Chromium helps insulin work properly, and low levels are associated with impaired glucose tolerance — so it's worth ruling out as a hidden factor behind your numbers.
Dose or use Ask your healthcare practitioner about checking your chromium status and dietary intake.
Key study Correcting a documented shortfall can support recovery; this is a root-cause check, not a treatment claim — ask your provider about your levels.
