Several friends seem to have jumped on the supplements bandwagon recently (collagen, magnesium, creatine) and I'm wondering how worthwhile they are.

Have you notified any positive effects or side effects?

Creatine - gives definition to muscles and helps with afternoon brain fog
collegen - skin and nails and hair all lovely still

magnesium - absolutely helps me to sleep

I was having marine collagen. Wasn't sure if they were making any difference..Then I heard something on the radio where the experts say there's no evidence that the pills can do what they're claimed to do so I won't be buying any more now.

I've seen mixed messages about supplements generally and specially collagen but I'm willing to give it a go as long as I'm satisfied it's not problematic.

I used to like Berocca and I'm tempted to get some of that as well but it might be a bit of a placebo. I always felt like it was good for me but can't say I felt any difference.

I can imagine it would be ok in a smoothie but again it's not something I do daily but maybe I should!

Smoothies are great! I usually do kale, frozen pineapple, an apple, a lime and a bit of greek yoghurt. I think it boosts my energy and makes me more regular.

It depends on your age, your health, your diet and any medical conditions what supplements you should take and what effect they might have. You can't generalise about it.

GeorgeMichaelsCat · 07/04/2026 14:43

I do:

Marmite
B12 supplement
Vitamin C
Zinc
Fish Oil
Magnesium Glycinate
Multivitamin
Collagen

MrsPottscloset · 07/04/2026 14:45

Absolute game changer for me since I followed a healthy eating and no ultra processed food diet. I lost 2 stones and feel years younger than I am (56) I take the following supplements......
Electrolytes
Bovine Collagen
DIM
Biotin

ThePoshUns · 07/04/2026 15:40

What’s DIM?

I don't think there are any particular downsides to taking collagen.Besides wasting money..

I take iron as my ferritin levels are really low (as a blood donor I ended up with severe anaemia- 6 months on prescription iron so now take it every day)

magnesium which does help with sleep

vit D as was deficient on last blood test

evening primrose oil & cod liver oil as beauty therapist said I should at my age - no idea what it’s meant to do but won’t harm me

collegen as 60 this year, not taking any chances! It’s not expensive (take capsules- powder was 🤮) so I’m happy to take it - just in case!

was taking a multi vit but my b12 was over 1,000. Caused GP to panic - turned out it was my vegan/vegetarian multi vit, just way too much vit b12! Will retest in a year to make sure it’s reducing (tends to be a slow reduction). If still as high - will be investigated so fingers crossed it’s coming down

I'm not trying to generalise but then how do you work out what you specifically should take when the advice is quite unclear?

WobblyBoots · 07/04/2026 18:54

44 and exercise a fair bit.

vit d, b complex and folic acid. Flagged that I was low in these at a GP blood test, started taking and am no longer low but honestly don't feel any different (am assuming there is some long term benefit!).

started magnesium as I have trouble sleeping. Gave me TERRIBLE wind and made no difference. Started creatine as I was told it would help with muscle loss, also abandoned due to terrible wind!

Magnesium gummies
Menopause gummies
Vitamin D
Turmeric & black pepper
Biotin
Immune system gummies
Pycnogenol
Cod liver oil

I don't know if it's all in my head but I have a joint condition and restless legs that are so much better since I started taking them. My hot flushes have also reduced significantly.

I stopped buying collagen gummies after reading this by Dr Karen in his weekly newsletter The Weekly Dose - Episode 173

December 28, 2025

“Why You Should Never Buy Gummy SupplementsThere are many mysteries in healthcare but few confuse me more than this: supplements in gummy form.
It’s the Trojan Horse of “wellness,” sneaking micronutrients into your diet via a delivery system that looks suspiciously like something a toddler would trade for stickers…I too fell for this hoax and I get the appeal.

Compliance is easier…they taste good and the branding is fun. It feels like you’re treating yourself and your health at the same time. Unfortunately…your biochemistry disagrees.
Here’s what most people don’t know:

  1. Nutrients decay in gummies, very fast.
Gummies are basically where vitamins go to die. Heat (how gummies are moulded), humidity, oxygen, light all accelerate degradation and unlike tablets or capsules, gummies have no hard protective shell, so nutrients are exposed from day one. Even when they’re “third-party tested,” the question that matters is: Tested when? Because testing the batch at manufacturing tells you NOTHING about what’s left 3 months later, or after sitting in a warehouse or the back of your cupboard like a forgotten bag of Haribo. Many nutrients have steep decay curves like folate, vitamin C, and many Bs…they degrade quickly in moist, gummy environments

What you think is 100% RDA may be 30–40% by the time you swallow it.
2. Gummies have dosing limits
You can’t pack meaningful amounts into a gummy without turning it into a chewable brick. This is why creatine gummies are a joke (ask me how I know…) Most gummies rely on pixie-dust dosing, sprinkling just enough to list it on the label.
3. Gummies need sugar, binders, stabilisers
To make them chewable AND shelf-stable, companies add:

  • Glucose syrup
  • Sugar
  • Gelatin or pectin
  • Oils
  • Colours
  • Flavourings
None of these are inherently evil but when you're taking a “health product,” you probably didn’t intend to eat a tiny dessert. 4. They’re often under-dosed by design Gummy manufacturers know you’ll eat 2 per day max. So they simply don’t include therapeutic doses. Not because they’re unethical but because gummies physically cannot hold them. It’s like trying to mail a sofa using a shoebox. My personal gummy disaster Once upon a naïve time, I bought creatine gummies. I thought: This is it. The future. Science + convenience. What I actually bought was blue raspberry-flavoured lies. The serving size required more gummies than a small child eats during Halloween.

So what should you actually take? (+examples of what I take)
Keep it boring, efficient and real. My supplement stack is intentionally simple:
Creatine monohydrate, unflavoured powder: clinically effective, dirt cheap and zero nonsense.
LOAM (prebiotic fiber blend): I take it daily because fiber is the unsung hero of metabolic, gut, and immune health. Consistency > perfection. (P.S we’re doing a new year sale on the site right now if you want to check it out!)
Vegan Omega-3 (EPA/DHA: Good for brain, inflammation and overall long-term health.
Vitamin D3 + K2: Particularly important in the UK, where our sunlight strategy is “hope for the best.””

I’m on medication that causes night sweats as well - what’s the bontella? I googled it but couldn’t find it! Thanks xx

Sorry, that was either a spectacular auto-correct or me typing before coffee, but it should have been Bonafide's Thermella, which should be more easily google-able!

It's an OTC herbal supplement that my oncologist recommended trying. It claims to take 3 months to kick in, and I've been taking it for about 9. I'm somewhat sceptical about it, as I said, not sure if it's working or if it's just been much colder! But I'm still taking it. I'm in the US at the moment and not sure if it's available in other markets.

Dh had restless legs syndrome. Doctor wanted to prescribe a medication with known side effects likely to promote risky and dangerous behaviour. He takes iron supplement instead. No restless legs!

angielizzy1 · 07/04/2026 19:42

I take apple cider vinegar capsules which dramatically reduce acid reflux, I used to regularly wake up choking on acid, even on ppi medication which are really bad for you long term as they prevent you absorbing vitamins and minerals (I ended up with a calcium and phosphate deficiency which I had to take for a while to correct along with vitD and K2)
Magnesium helps me stay asleep for longer if I take it everyday it gives me about an hour's extra sleep a night.
Woman's probiotic that is supposed to prevent UTIs (not sure it works as I was saying how well is been feeling since taking it and that I hadn't had any stomach pain then got a bad UTI and was peeing blood so definitely not preventing UTIs but hoping it will help with general mild stomach pains (the Dr thinks it's gastritis so waiting for a few weeks to see if it improves)
I've got vaginal oestrogen for UTIs, had terrible side effects for the first 2 months when it made everything very dry and the skin split constantly but I was convinced to persevere with. I'm now it's really helped the scar tissue from the tear why don't you have a nightie the best I didn't see one at the end of bed oh here it got buried in the doubt was the one I was wearing oh I'm wearing this one now when I had my son (who is 16)soften and I've not had a UTI so far but it's only been a 4 months so may just be a coincidence.
My daughter is studying biochemistry and tells me collagen is pointless because your body breaks down every protein you eat into it's component amino acids and then rebuilds them into whatever you need, you don't actually get more collagen in your body by eating it if you're body has other plans for the amino acids. Just make sure you eat enough protein from varied sources.

I take Iron, because my ferritin levels were only 1 point into range, and I now no longer look grey and have colour in my cheeks. I take vitamin B for the same reasons, i.e. my B12 levels were just out of range and I was perma knackered. I do reckon it has helped. I'm not losing as much hair any more either.

loubielou31 · 07/04/2026 21:11

I take a multivitamin sometimes and really need to remember to take the vitamin D.
I have recently started adding chia and linseed to my breakfast which has had a hugely beneficial impact on my bowels and consequently my general wellbeing.
There was a radio 4 sliced bread episode about collagen supplements, the main conclusion is they are not worth it so I will happily save my money.

Biotin after birth, for my hair as it was a breaking mess - I noticed a big difference after about 4months. Ive continued to take it & the health of my hair is amazing 👏

CamillaMcCauley · 07/04/2026 21:51

Just turned 50 and take

  • Vit D/K2 and a fish oil capsule at breakfast
  • In winter zinc with lunch
  • Magnesium glycinate after dinner, and if the dinner didn’t involve any dairy, a gentle iron capsule

The fish oil has definitely helped my fingernails (used to be flaky and short, now they are long enough that they look like fake ones!) skin texture and joints.

No noticeable difference from the Vit D but I take it for my bones as I spend almost no time in the sun (so don’t need collagen).

Since taking iron my hair has noticeably thickened and it helps energy.

Rarely get sick in winter and a friend who I put onto zinc swears it has been life-changing for him in that regard.

Absolutely notice if I don’t take magnesium as I get restless legs.

Am considering adding a B complex in the morning and creatine once I step up my exercise routine as these seem to be well-evidenced.

Merseymum1980 · 07/04/2026 21:55

Vitamin d as doc said i was critically low.
Helped my hair ,nails and tierdness

mohammedchungus · 07/04/2026 21:57

Creatine - definitely the leanest and most muscle I’ve ever had. I’d already worked on nutrition and then added creatine and definitely got even better results. I had been nervous before taking it but just make sure you drink plenty of water with it.

Crushed23 · 07/04/2026 22:00

I take the following daily:
Collagen powder
omega 3-6-9
L-carnitine
B12
vitamin D
Magnesium

The only thing I noticed making a difference was the collagen powder on my joints - my knees used to ache and now they don’t.
