Why Your Current D3 Supplement Is Probably Useless (And Possibly Harmful)
Despite living in the UK where sunlight is scarce 8 months of the year, most people are still deficient in vitamin D even while taking supplements. Why? Because the supplement industry has been lying to you about effective doses.
Despite living in the UK where sunlight is scarce 8 months of the year, most people are still deficient in vitamin D even while taking supplements. Why? Because the supplement industry has been lying to you about effective doses.
The dirty secret: Most D3 supplements use doses so low they're basically expensive placebo pills. 400IU? 1,000IU? These aren't recommended doses - they're marketing doses designed to keep you buying while keeping you deficient.
The real scandal? They know this. But there's no money in actually solving your vitamin D deficiency. There's massive profit in keeping you sick and dependent."

UK Latitude Problem
Living at 51-60°N latitude means the UK gets almost zero vitamin D-producing UV-B radiation from October to March. That's 6 months of vitamin D winter.
British Supplements D3+K2 Dose Vs Typical UK Supplement Brands
Most UK Supplement Companies under-dose your D3+K2 at 400-1,000IU while we at British Supplements dose ours at 4,000-10,000IU to try and ensure you’re at the optimal levels. Mainstream brands underdose their products and still wonder why you’re still deficient.

35,598+ Reviews They Don't Want You To Read
The FSA and trading standards keep trying to censor these reviews because they show what really works. We're keeping them up anyway - it's called freedom of speech.

"i can't express enough of how life changing taking a good dose of this vitamin could /can be . Having read jeff t bowles and Judson Somerville books on it i'm on optimal dose .I give my body a rest on fasting days and when i'm enjoying the Gambia sunshine .I take a zinc ( app we short of that and helps d3 absorb ) B12 ( most short that too) daily as well as Boswellia Astaxanthin and Biotin . i thank Chris for knowing his vits and for giving us them without all the bulking nasties in"

"Since I started taking the vitamin D3+K2 (D3 at 10,000 iu) some 6/7 weeks ago, it has to be said that there has undoubtedly been an increased feeling well being. I had been taking vitamin D3 (400 iu's) from another supplier until I discovered from different sources that these amounts of IU's were hopelessly inadequate. Now I'm back to doing my little bursts of 100 metre sprints and walking at a quicker pace with my wife, enjoying a complete absence of wobbliness and dizzy spells."

I started using British Supplements a few years back and have never been disappointed in their service and products. I fully trust in the quality of the contents and will continue to use them.
The shocking reality
Here's what most people don't realize: 99% of supplement companies don't manufacture anything. They're essentially marketing offices that buy generic pills from mass production facilities, slap their label on them, and sell them to you for 500% markup.
No manufacturing
facilities
No quality control
labs
No ingredient
sourcing
Just fancy websites
and paid advertising
They buy the same generic pills as everyone else, put their brand name on the bottle, and convince you they're somehow different.

The Real Reason Most Supplements Contain Fillers
These factories are designed to turn out a million pills per hour for wholesale distribution. Speed is everything. Quality is nothing.
To hit these insane production speeds, they need:
Flow agents so powders slide through machines faster
Anti-caking agents so nothing sticks to equipment
Binding agents so tablets don't crumble at high speeds
Lubricants so pills pop out of molds quicker
None of these serve your health - they serve the machine.
Here Today, Gone Tomorrow vs 10 Years Strong
Most supplement 'brands' disappear within 2 years. Why? Because they were never real companies - just marketing experiments.
