These are supplements that I recommend and have found very useful personally. All information and recommendations are based purely on my personal experience with these products and I would always suggest consulting a nutritionist or your doctor before supplementing your diet.
Matcha Green Tea Powder from Eternal Vibrance – I first started taking this to help increase my energy levels (I suffer from Lupus, an auto-immune disease which can cause chronic exhaustion). It is a source of natural caffeine and contains anti-oxidants which combat inflammation. I also think it’s helped with my focus – I often get distracted and this has definitely helped with my concentration. Eternal Vibrance have a free sample on their website that you can order to try it out.
