Cinnamon

Cinnamon, a common spice, has potential benefits for blood sugar control. Research shows it can increase insulin sensitivity and improve glucose uptake into cells.

One study found increased insulin sensitivity for at least 12 hours after cinnamon consumption, with other evidence suggesting effects lasting up to two weeks.

This could be due to cinnamon’s ability to inhibit α-glucosidase activity, slowing carbohydrate digestion in the small intestine. Additionally, cinnamon has been shown to reduce fasting blood sugar by 24 mg/dL in people with type 2 diabetes.

Sources of Cinnamon:

• Cassia: Common in food products and grocery stores. Contains coumarin, which can be toxic to the liver in high amounts. Limit intake to 0.5-1 g/day.
• Ceylon: Contains trace amounts of coumarin, making it safer for high doses.

Dosing Recommendations:

• Tolerable daily intake for coumarin is 0.1 mg/kg of body weight, about 1 teaspoon of cinnamon per day.

Precautions:

• May interact with diabetic medications, increasing the risk of hypoglycemia. Consult a doctor before use.

Ginseng

Ginseng, particularly American ginseng (Panax quinquefolius), has been used in Chinese medicine for centuries to boost well-being and energy.

Studies show it can regulate glucose uptake, decrease blood glucose levels, and lower insulin. Research indicates significant improvements in fasting glucose levels among type 2 diabetics taking ginseng supplements.

However, ginseng’s effects are less pronounced in prediabetes or healthy adults.

Sources of Ginseng:

• Naturally sourced from the root, which can be used in tea, steamed, or eaten raw.
• Available in supplement form as powder, gummies, capsules, tablets, and oils.

Dosing Recommendations:

• Safe short-term use at 100-3,000 mg/day for up to 12 weeks.

Precautions:

• Generally well-tolerated but may cause headaches, diarrhea, or skin irritation. Not recommended for infants, children, pregnant women, or those with hormone-sensitive conditions.

Probiotics

Probiotics support immunity, digestion, and heart health, with emerging evidence suggesting benefits for blood sugar control. Certain strains (e.g., Lactobacillus acidophilus, Bifidobacterium lactis) can reduce HbA1c and fasting glucose levels.

Studies show type 2 diabetics experienced lower cholesterol and blood pressure after taking probiotics for over eight weeks.

Sources of Probiotics:

• Naturally found in fermented foods like yogurt, kefir, sauerkraut, kimchi, and kombucha.
• Available in supplements, recommended to contain at least 1 million CFUs/gram.

Precautions:

• Generally safe, but consult a doctor for the appropriate dosage.

Aloe Vera

Aloe vera, a plant native to the Mediterranean, India, China, and Eastern Africa, is widely used in cosmetics and pharmaceuticals. Research shows it can lower glucose levels after meals and stimulate sugar breakdown.

One study found a 1.05% decrease in HbA1c and a 46.6 mg/dL reduction in fasting blood sugar with oral aloe vera supplements.

Sources of Aloe Vera:

• Available in supplements and juice form.

Dosing Recommendations:

• No established dosage, but supplements range from 100 mg to 10,000 mg. Lower doses are recommended to minimize side effects.

Precautions:

• May cause diarrhea, abdominal pain, and cramping. Interacts with certain medications, reducing their effectiveness. Consult a healthcare provider before use.

Berberine

Berberine, a compound found in several plants, is used to treat various health conditions, including high blood sugar.

Studies show a 20% and 12% reduction in fasting and long-term blood sugar levels, respectively, in type 2 diabetics taking berberine with medication.

It improves insulin sensitivity, glycolysis, insulin production, and reduces glucose production and carbohydrate absorption.

Sources of Berberine:

• Only available through supplements.

Dosing Recommendations:

• No established RDA, but research doses range from 1,000 to 1,500 mg/day.

Precautions:

• Generally safe but may cause gastrointestinal issues. Interacts with medications processed by the liver. Not recommended for infants, children, or pregnant/breastfeeding women.

Vitamin D

Vitamin D, known as the sunshine vitamin, supports bone health, immune function, and glucose metabolism. Low vitamin D status is linked to elevated HbA1c levels.

Supplementation can improve insulin sensitivity, particularly in those at risk or newly diagnosed with type 2 diabetes.

Sources of Vitamin D:

• Obtained through sunlight, fatty fish, mushrooms, egg yolks, and fortified foods. Supplementation may be necessary for adequate intake.

Dosing Recommendations:

• RDA for ages 1-70 is 600 IU/day; adults over 70 need 800 IU/day. Recent research supports up to 10,000 IU/day safely.

Precautions:

• Excessive intake (>10,000 IU/day) can cause health issues, including heart and kidney damage.

Gymnema

Gymnema sylvestre, a shrub used in Ayurvedic medicine, inhibits sugar absorption and stimulates insulin production. It can decrease fasting and long-term blood sugar levels.

Sources of Gymnema:

• Traditionally consumed as tea, available in tablet, pill, or extract form.

Dosing Recommendations:

• Recommended dosage is 200-400 mg, under doctor supervision.

Precautions:

• May cause hypoglycemia when combined with other diabetic medications. Not recommended for children, pregnant, or breastfeeding women. Consult a healthcare provider before use.

Magnesium

Magnesium supports nerve and muscle function, heart rhythm, blood pressure, and glucose levels. Studies indicate those with diabetes taking magnesium have better blood sugar regulation and a lower risk of developing diabetes.

Sources of Magnesium:

• Found in sunflower seeds, almonds, and spinach. Available in supplements.

Dosing Recommendations:

• Varies by age and gender. RDA for males 19-30 years is 400 mg/day, for females 310 mg/day.

Precautions:

• May increase the risk of hypoglycemia when combined with other medications. Consult a healthcare provider before use.

Alpha-Lipoic Acid (ALA)

ALA, an antioxidant, aids in converting glucose into energy and is linked to reduced heart disease risk, lower blood sugar levels, and improved insulin uptake. Studies show ALA can reduce fasting glucose, insulin resistance, and HbA1c levels in diabetics.

Sources of ALA:

• Found in red meat, organ meats, and plant foods like broccoli, tomatoes, spinach, and Brussels sprouts. Available in supplements.

Dosing Recommendations:

• Research supports doses of 300-1,800 mg/day for three months to four years.

Precautions:

• Generally safe, but consult a healthcare provider if diabetic, as ALA may interact with glucose-lowering medicines. Not advised for children, pregnant, or breastfeeding women without medical supervision.

Chromium

Chromium, an essential trace mineral, can improve insulin sensitivity and enhance metabolism. Supplementation may reduce the risk of developing type 2 diabetes by 27%.

Sources of Chromium:

• Found in meats, grains, fruits, vegetables, nuts, spices, and brewer’s yeast.

Dosing Recommendations:

• DRI is 35 mcg/day for adult men, 25 mcg/day for adult women. Research indicates 200-400 mcg/day can be beneficial.

Precautions:

• Deficiency is rare, but supplements should not be taken by pregnant or breastfeeding women without consulting a healthcare provider.
