Shaking up your supplement routine? Don’t just settle for anything – 2025 is the year you get “supplement smart”.
We optimise ingredient combinations for maximum efficacy, ensure the best timing for absorption and provide a range of formats. That might be adding vitamin C to our collagen capsules or putting extra vitamins in our omega-3 offerings. Quite simply, we put more into our products so that you can get more out of them.
That's why we're shouting about some of the products we're proud of, with new ingredients, multitasking minerals and enhanced formulations.
Vitamin D's good, but vitamin D3 is considered to be even more superior. Why? Well, if you have ever heard about sunlight giving you vitamin D, it’s actually D3 rather than straight up vitamin D that it gives you.
D3 is more easily absorbed by your body, so if you’re going to take vitamin D, this is the way to go.
The NHS suggests adults supplement with 10 micrograms (400IU) a day during autumn and winter, when sunlight is scarce, as it's tough to get enough from diet alone.
Our best-in-class D3 supplements, made from the most scientifically-studied form, come in a variety of strengths to suit your daily needs.
In addition to supporting immune function, bone health and muscle function, vitamin D also contributes to the normal absorption and use of calcium and phosphorus – essential minerals for your body.2-5
Optimise your vitamin D3 absorption by pairing it with a meal rich in healthy fats, like avocado, nuts or olive oil.6
Show your heart the love it deserves with a little help from our H&B scientists and the high strength 3-in-1 omega capsules they’ve formulated for you.
This triple whammy of omega is designed for happy and healthy hearts, brains and eyes, and we’ve also added flaxseed and starflower oils for extra support.
We've carefully crafted a powerful formulation, combining fish oil, a rich source of omega-3 fatty acids, with flaxseed and starflower oils for an extra, hearty boost and a balanced and sufficient supply of essential fatty acids.
Each dose packs 250mg of EPA and DHA – two vital omega-3 fatty acids.7
Plus, the omega-3s in fish oil, particularly DHA, play an active role in supporting brain and eye health.
Calcium for bones – we’ve all heard it’s good for them. But, at H&B, we go that little bit further by adding magnesium, vitamin D and zinc to our calcium supplement.
Why? Well, we’re always thinking about how we can help you get the best from your supplements.
The addition of vitamin D helps your body absorb calcium, while magnesium is vital in activating vitamin D. Clever, right?
Let's break down these four powerhouse ingredients and why we put them together to support your bone health.
First up, calcium takes the spotlight, essential for bone health.
Next, vitamin D steps up to the plate, one of the body’s most important vitamins, helping it with a variety of tasks, like contributing to the normal function of the immune system and maintaining normal bone and muscle function by enhancing calcium absorption and utilisation.2,4
Magnesium plays a pivotal role, supporting normal bones and muscles, while also reducing tiredness and fatigue.8 It also supports bone mineralisation.
Finally, zinc joins the team, supporting the immune system and contributing to normal fertility, reproduction and the maintenance of normal vision and cognitive function.9-12
We want you to get the very best from your supplements, which is why we’re combining our High Strength Turmeric with – wait for it – black pepper.
It might sound like a surprising pairing, but research suggests that black pepper helps with the absorption of turmeric in the body. We put more in, so that you get more out.
To support your joints, we've supercharged our H&B Extra Strength Turmeric with black pepper to keep you moving and feeling flexible. Simply take one daily with food and a glass of water.
Magnesium can power up your day and keep fatigue at bay, but we’ve specifically chosen magnesium citrate. Why? It’s the superior, organic form of the vital mineral that your body can absorb and utilise more easily compared to other magnesium salts.14
Magnesium is the secret weapon behind ATP production, your body's top energy source. And a lack of this can leave you battling fatigue and tiredness.15
Magnesium citrate helps to optimise the body's absorption of magnesium to help maintain your energy levels and support the maintenance of normal bones and muscles.16
Our H&B scientists know how important magnesium also is for normal muscle function, healthy bones and even psychological wellbeing. It plays a pivotal role in numerous enzymatic pathways, including energy production within cells, nerve transmission, muscle contraction and protein synthesis.17
There’s vitamins A, B, C… but what about the rest? We’ve got you covered for (nearly) the whole alphabet, with the perfect combination of 23 vitamins and minerals your body needs most.
Even better, it’s all simplified into one mighty tablet!
From vitamin A to zinc, all 23 vitamins and minerals work together helping to optimise your health and wellness.
Think calcium and magnesium for the maintenance of muscles and bones, alongside the likes of biotin for energy, and folic acid and iron for healthy red blood cells.18,19,20
Why take collagen when you can take marine collagen that’s combined with the thing that makes it work even harder - vitamin C?
We’re always thinking about how we can give you the very best through our formulations. Not only is marine collagen more efficiently absorbed by the body than some other forms, but the clever addition of vit C also helps with normal collagen formation for the normal function of cartilage, bones and skin.
Our skin is made up of 90% type I collagen which marine collagen (from fish) is most abundant in.21 And as vitamin C supports normal function of the skin, this dreamy marine collagen combo will help to give you healthy looking skin and enhance that sought-after, natural glow.
Reel in the benefits of our cod liver oil capsules, with a few added extras.
Not your typical catch, we've sourced 100% pure cod liver oil which contains a source of omega-3 fatty acids with added vitamins A and D.
As well as offering a source of omega-3 fatty acids, EPA and DHA, these capsules help to maintain normal vision, heart and brain function. The beneficial amount is met with a daily intake of 250mg of EPA and DHA.22,23
What's more, vitamins A and D both contribute to the normal function of the immune system, while vitamin A alone contributes towards the maintenance of normal skin, and vitamin D contributes to the maintenance of normal bone and muscle function.4,24,25

What's more, thanks to the added vitamin D, they also support the normal function of your immune system.
