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 super ingredients, multitasking minerals and enhanced formulations.
Did you know vitamin D3 is the most bioavailable and superior form of vitamin D?
Our bodies produce it naturally when exposed to sunlight and it can be found in foods like egg yolks and fatty fish, such as salmon and mackerel.1
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 of vitamin D, come in a variety of strengths to suit your daily needs.
In addition to supporting immune function, bone health and muscle function, they also contribute 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
We've carefully crafted a powerful 3-in-1 formulation, combining fish oil, a rich source of omega-3 fatty acids, alongside flaxseed oil and starflower oil to provide a balanced and sufficient supply of essential fatty acids.
Give your heart the love it deserves with these capsules, scientifically designed to support heart health. 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.
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 maintaining normal bones.
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
Forget salt and pepper. This is the pairing you want to hear about, as black pepper actually promotes the absorption of turmeric in the body.
Well, we’ve added it to our turmeric capsules for exactly this reason. Enter our very own power couple: the black pepper supports your body's ability to absorb the compounds found in turmeric, such as curcumin.13
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.
We've developed these tablets using the more bioavailable form of magnesium: magnesium citrate.13
This is because research indicates that this form is absorbed and utilised by the body more effectively than many other magnesium salts.14
Magnesium is the secret weapon behind ATP production, your body's top energy source. As a lack of this vital mineral 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
Magnesium is a vital nutrient that plays a pivotal role in numerous enzymatic pathways, including energy production within cells, nerve transmission, muscle contraction and protein synthesis.17
Looking for an all-rounder? We've carefully crafted our H&B multivitamin with the perfect balance of the 23 vitamins and minerals your body needs.
From vitamin A to zinc, all 23 vitamins and minerals work together helping to optimise your health and wellness. Think calcium and magnesium for maintenance of muscles and bones, alongside the likes of biotin, folic acid and iron.
Meet your skin's dynamic duo: we’ve added vitamin C to our hydrolysed marine collagen to help support skin and enhance your natural glow.
Did you know that taking vitamin C contributes to normal collagen formation?18
As vitamin C supports normal function of the skin, this dreamy marine collagen combo will help to give you healthy skin and enhance that sought-after natural glow.
Reel in the benefits of these 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 also help to maintain normal vision, heart and brain function.19 The beneficial amount is met with a daily intake of 250mg of EPA and DHA.
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.4,20,21
Looking for a combination that helps support your immunity while keeping your gut happy? We've packed in a whopping 35 billion friendly bacteria and combined it with calcium and vitamin D.
These gut-supporting ingredients have the additional help of calcium, which contributes to the normal function of digestive enzymes (the proteins that break down food into smaller pieces, helping our bodies absorb nutrients more easily).22
What's more, thanks to the added vitamin D, they also support the normal function of your immune system.
The final say
We only want the best for you, that’s why we add ingredients that work hard together.
Whether you're combining your gut health with immunity support, seeking a multivit marvel or looking to enhance the absorption of other supps - we've got you covered.
