Walk through any health store or scroll online, and you’ll find hundreds of supplements promising more energy, better focus, faster metabolism, and fewer cravings. But which ones actually support your health, and which ones are just hype?

Here’s a breakdown of common supplements that may be helpful, and others that are often unnecessary or even risky, especially for those managing diabetes, weight, or metabolic health.

✅ Supplements That May Help (When Used Correctly)

These show meaningful benefits in studies and are generally used under healthcare supervision.

1. Magnesium

Many people are mildly deficient. Magnesium supports blood sugar control, muscle function, and sleep.

• Forms to look for: Magnesium glycinate or citrate

• May help with: Cravings, fatigue, headaches, insulin sensitivity

2. Vitamin D

Low levels are common, especially in colder climates or with limited sun exposure.

• Supports: Mood, bone health, insulin function

• Tip: Always test levels before supplementing to avoid overdose

3. Omega-3 Fatty Acids (Fish Oil)

Found in fatty fish, but hard to get enough through diet alone.

• May help with: Inflammation, triglycerides, heart and brain health

• Look for: High-quality, mercury-free sources

4. Berberine

A plant compound shown to support blood sugar and cholesterol levels, similar to metformin in some studies.

• Best used: Under supervision, as it can interact with medications

• Not ideal: During pregnancy or in combination with multiple prescriptions

5. Fiber (Psyllium Husk, Inulin, Acacia)

Helps slow digestion, stabilize blood sugar, and support gut health.

• Choose: Powders or capsules with no added sugar or artificial sweeteners

• Tip: Start slow to avoid bloating

6. Alpha-Lipoic Acid (ALA)

An antioxidant that may improve insulin sensitivity and help with nerve pain.

• Especially helpful for: Diabetic neuropathy symptoms

• Use caution: If taking thyroid medication or blood sugar-lowering drugs

7. Vitamin B12

Deficiencies may occur with some medications like metformin or in people following plant-based diets.

• Supports: Nerve health, red blood cell production, energy metabolism

• Tip: Best absorbed in methylcobalamin or cyanocobalamin forms; consider sublingual or injections if absorption is an issue

⚠️ Supplements to Be Cautious With

These are widely marketed but either lack strong evidence or carry unnecessary risk.

1. Fat Burners and Metabolism Boosters

Often contain caffeine, synephrine, or other stimulants that raise heart rate or blood pressure.

• Risks: Jitters, blood pressure spikes, arrhythmia

• Better approach: Support metabolism with sleep, resistance training, and balanced meals

2. Detox Teas or Cleanses

Usually contain laxatives or diuretics that cause temporary weight loss through water and stool.

• Risks: Dehydration, electrolyte imbalance, and gut irritation

• Reality: Your liver and kidneys detox naturally every day when functioning properly

3. High-Dose Multivitamins

Mega-doses of vitamins and minerals may do more harm than good, especially with fat-soluble ones like A, D, E, and K.

• Safer option: A basic multivitamin with moderate levels, if your diet is limited, and discuss with a healthcare provider

🧠 The Bottom Line

Supplements can be useful tools, but they’re not magic bullets. The best results still come from consistent sleep, balanced nutrition, movement, and stress management. Before adding anything to your routine:

• Check with a healthcare provider who may check lab levels to see if you actually need it

• Ask about interactions with your current medications

• Buy from trusted brands with third-party testing
