The Big 4
For Mental health

The Big Four® is our signature bundle designed to support those with low energy and low mood.  Trusted by thousands of people in the Mad Diet community, these four nutrients may help improve cognitive function and benefit the gut-brain axis.

Magnesium is vital for normal brain function but today many of us do not consume enough. This calming mineral helps regulate mood by balancing chemical compounds in the brain.

Choose between Magnesium citrate for additional digestive support or Magnesium bisglycinate to help balance hormones and aid sleep.

Docosahexaenoic acid (DHA) is the most abundant fatty acid in the brain and is a structural component of cell membranes.  Eicosapentaenoic acid (EPA) improves blood flow in the brain and helps stabilise mood.  Both DHA and EPA may help reduce neuroinflammation.

Psychobiotics are beneficial bacteria that influence the gut-brain axis. Our proprietary probiotic formula contains specially selected strains to help enhance GABA, glutamine, and other brain metabolites.

B vitamins play a crucial role in making brain chemicals that affect mood and cognitive function. Our high strength formula contains all the B vitamins, including methyl folate and methylcobalamin the most bioavailable forms of B9 and B12.

F. Dusk

I love that this Vitamin C supplement comes with zero additives, making it feel incredibly clean and trustworthy. The 1000mg capsules provide a great boost for my immune system, and it’s reassuring to know that it’s sourced locally and held to practitioner-quality standards. It does take time to see noticeable results, but with patience, the immune support it offers feels worth the wait!

I lack in Vitamin D so it’s great to have a supplement that is easy to swallow and good value for money as it includes K2 too. Good level at 2000iu too and great that this is made in the UK as following proper manufacturing protocols is nice to know.

Good quality pure vitamin C. I also like that there is nothing in the capsule except for Scottish ascorbic acid. Since taking these I do seem to have a stronger immune system, as I haven’t had a sniffle or even a hint of a cough, despite being out daily in all weathers. Happy with the quality and purity of this supplement. A bit pricier than others, but it has a unique selling point and you are contributing to helping keep a unique Scottish facility going.

Very interesting book and the author is very knowledgeable. Some eye opening stuff in there. I took her advice on the vitamins and feel better already.

I cannot praise this book highly enough. It’s the first “self help” book I have ever read from cover to cover. It makes so much sense and I have now changed my relationship with food, taking the big four as well as some other supplements. Thank you Suzanne – you have changed my life for the better.

I ordered these for my partner who finds additional magnesium helpful. He has been taking them regularly and in his usual effusive manner described them as being ‘alright’ From him this is glowing praise so I’ll have to give these full marks.

My life has turned around since I read this book and started using their supplements. I work long hours with a chronic condition, and used to spend my days off in bed to re-charge. That no longer needs to happen. My hair has got thicker, my nails are stronger, and I’m sailing through the menopause. Thoroughly recommended.

These black turmeric capsules have been fantastic for my joint health and overall energy. I noticed my digestion feels smoother, and the anti-inflammatory effects are a real plus. The capsules are easy to take, and I love that they’re organic – definitely a must-have for wellness.

The supplements are amazing! You really do notice a difference after taking them, and the quality is so much better than what you get in the high street, and for a better price too!

These organic black turmeric capsules have been a real game-changer for me, especially when it comes to managing joint discomfort and general inflammation. With all the lifting, bending, and running around I do (thanks to my little one’s boundless energy), my joints were starting to complain, and I needed something natural to help keep me moving comfortably. These capsules have delivered noticeable relief.

Fantastic customer service! I placed a large order which hadn’t arrived. I phoned Mad Diet who were very apologetic and resolved the issue by sending out a replacement (even though it wasn’t their fault) and I was delighted when it arrived the next day. I shall definitely use again. Thank you.

Having taken Mad Diet supplements for a few years, I decided to try their Vegan Vitamin D3+K2. The small, easy-to-swallow capsules leave no aftertaste and are good value for money.

This brand of supplement is new to me, and I have to say I like what I see. The capsules are produced in Scotland with no artificial additives or any ingredients at all other than what you would get them for. This puts my mind at rest, since so many manufacturers steer away from this pure and simple approach.

I have recently started taking Magnesium Citrate from Mad Diet. I never expected it to make such a difference. I have had a lot of upper back pain together with neck and shoulder pain, literally for years, lately it had got so bad it was making me miserable. I have almost no pain in these areas after about 3 weeks of taking the Magnesium Citrate. I am over the moon, thank you. Can’t recommend highly enough.

I am a big believer in the healing qualities of Vitamin C and have used it in varying amounts to assist with different ailments. Having looked at the source of this product I’m very happy to endorse the quality and ethics of Mad Diet products. The quality and content of this Vitamin C is second to none and I love that you get 2 months daily supply thereby reducing the number of orders placed for restocking.
