Over the past few weeks, I’ve shared how I lost 10kg on a sustainable keto journey — with low-carb brunches, high-protein dinners, and intermittent fasting as my foundation.
I didn’t follow a rigid plan. I made it work for my life — nourishing, balanced meals that fit my goals. It was all about low carb, high protein, and staying full, not frustrated.
But let’s be real — while the weight was dropping, my body went through a few challenges. Fatigue, brain fog, headaches, and that infamous “keto flu” came and went. This is where the right supplements made all the difference.
In this post, I’m sharing the Top 5 supplements that helped me stay energized, reduce side effects, and stay consistent on my keto journey. If you're starting keto or struggling to stay on track, these might help you too!
💊 Top Supplements That Supported My 10kg Keto Weight Loss Journey
When I started my keto diet, I didn’t follow a strict or rigid plan. Instead, I focused on what worked for me: low-carb brunches, high-protein dinners, and intermittent fasting. Through this balanced approach, I was able to lose 10kg while still enjoying my meals and keeping my energy up.
But like many others on a keto journey, I also faced some common side effects — fatigue, headaches, brain fog, muscle cramps, and occasional constipation. That’s when I realized that certain supplements were not optional, but essential to support my body through fat adaptation and long-term sustainability.
In this post, I’ll walk you through the top supplements I personally used, why they helped, what symptoms they addressed, and what roles they play in the body. I’ve also added a few more recommendations that are popular and evidence-supported for keto beginners.
🧠 1. Magnesium
Magnesium was a lifesaver for me in the early stages of keto. It helped relieve muscle cramps, supported better sleep, and calmed my nerves on tough days. I also noticed improved digestion and reduced fatigue when taking magnesium regularly.
Body function: Supports nerve and muscle function, promotes relaxation, improves sleep quality, and balances electrolytes.
When to take it: If you experience muscle cramps, insomnia, irritability, or symptoms of “keto flu”.
💊 Recommended Magnesium Supplement
Supports sleep, muscle relaxation, and helps reduce keto-related fatigue and cramping.

💊 2. Multivitamin + Vitamin B Complex
Because keto naturally excludes many fruits and grains, it’s easy to miss out on essential micronutrients. I took a multivitamin paired with a B-complex supplement to cover all nutritional bases. The B vitamins specifically helped me maintain energy levels and stay focused during busy days.
Body function: Supports metabolism, reduces fatigue, maintains healthy brain and nerve function.
When to take it: If you're feeling drained or your diet lacks variety due to strict carb limits.
💊 B-Complex for Energy & Stress Support
This B-vitamin complex helped me maintain steady energy levels, reduce fatigue, and support my nervous system during keto — especially on busy, low-carb days.

🦠 3. Probiotics + Prebiotics
While keto can improve gut health for many people, it can also disrupt digestion for some — especially if your fiber intake changes suddenly. I used both probiotics and prebiotics to support a healthy microbiome and ease symptoms like bloating or constipation.
Body function: Probiotics deliver beneficial bacteria; prebiotics feed those bacteria to thrive and colonize the gut.
When to take it: If you're experiencing gut discomfort, irregular bowel movements, or adjusting to high-fat meals.
🦠 Probiotic + Prebiotic Blend for Gut Health
This supplement helped support my digestive system during keto, improving regularity, minimizing bloating, and enhancing nutrient absorption — especially important when consuming higher amounts of fiber and vegetables.

🥤 4. Fiber Supplement (Metamucil)
Here’s the surprising truth: Even though I was eating lots of vegetables, I still experienced constipation during keto. That’s because fiber needs water to move through the digestive tract — and without enough water, it can backfire. I added psyllium husk (Metamucil) on days when things got sluggish.
Body function: Adds bulk to stool, supports bowel regularity, and improves overall digestion.
When to take it: If you’re eating high-fiber veggies but still feel constipated. Always drink 2–3 liters of water per day with it.
💧 Electrolyte Blend for Hydration & Keto Flu Relief
This electrolyte supplement helped me prevent headaches, fatigue, and muscle cramps during keto adaptation by replenishing minerals lost through water loss on a low-carb diet.

⚡ 5. Electrolytes (Potassium, Sodium, Magnesium blend)
During the first two weeks of keto, I experienced headaches and fatigue — classic signs of electrolyte imbalance. This is common due to water loss on low-carb diets. I used a high-quality electrolyte blend to restore balance, boost hydration, and reduce “keto flu” symptoms.
Body function: Regulates hydration, supports heart and muscle function, prevents cramping and weakness.
When to take it: During keto adaptation phase, after sweating, or if you feel dizzy, weak, or lightheaded.
💧 Electrolyte Blend for Hydration & Keto Flu Relief
This electrolyte supplement helped me stay hydrated, reduce headaches, and prevent muscle cramps during the adaptation phase of my keto journey by replenishing key minerals like magnesium, sodium, and potassium lost on a low-carb diet.

🧈 6. MCT Oil (Bonus Recommendation)
Although I didn’t take this daily, MCT oil helped on days when I felt low on energy or needed a brain boost. It's rapidly absorbed by the liver and converted into ketones, providing quick fuel during intermittent fasting or between meals.
Body function: Enhances mental clarity, boosts energy, supports ketone production.
When to take it: During fasting windows, or when you need a boost of clean energy without breaking ketosis.
🧈 MCT Oil for Enhanced Energy & Ketone Support
This MCT oil helped fuel my keto diet by providing quick energy and supporting ketone production—ideal for fasting days or when I needed a brain-boost without breaking ketosis.

💧 Don’t Forget: Hydration Is Key!
When you eat more vegetables and protein, your body needs more water to process them. On keto, I made sure to drink 2 to 3 liters of water every day — especially when taking fiber or electrolytes. This not only improved digestion but also reduced sugar cravings and headaches.
✅ Final Thoughts
These supplements weren’t magic pills, but they supported my body through fat loss, energy crashes, and digestive changes during my keto transformation. If you’re just getting started or feel stuck, I highly recommend listening to your body and giving it the nutrients it needs.
