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?

Magmessium has changed my life

BatshitCrazyWoman · 07/04/2026 09:20

I've had cancer, and a fair few things are contraindicated - turmeric, for example.

I take vitamin D and calcium (prescribed)
K2
Sage (oncologist approved!)
Collagen (oncologist approved)
Magnesium glycinate (for restless legs and sleep, oncologist suggested it)

Considering I've been through chemo, surgery and radiotherapy, I feel really well!

I bought some women's health ones and didn't notice any difference at all.

Then as I was adding them to my doset box I realised they were for women's vaginal health. I hadn't noticed any change in my fanny so either they didnt work or my fanny was perfectly happy 🤷‍♀️🤦‍♀️

You've made my day already with this!🤣

EssaDiTractor96 · 07/04/2026 07:14

I take three.

Vitamin D after a bug knocked me out for ages last October. Haven't had even a cold since - unusual for me - while colleagues have dropped like flies

Magnesium - effects are definitely cumulative, but since I started taking it a year ago, I have never had such good quality sleep for the last 10 months

Bio kult probiotic. I notice if I don't take this for a few days.

MyballsareSandy2015 · 07/04/2026 07:07

menopace multi vitamin - def helps my mood, I feel low when I stop it and I’m generally a very upbeat person (late 50s)

glucosamine & chondroitin with turmeric and ginger - great for my joints. If I forget to take it my sore knee comes back.

pepayfelix · 07/04/2026 06:58

a good quality multivitamin
cod liver oil
probiotic
collagen

I don’t know what each one is doing specifically but I haven’t been ill for months and months, and I have two young DC. I started taking them after a long bout of back-to-back illnesses, broken nails, hair falling out, etc. I do feel miles better now.

Please be aware that you should only take ashwagandha for a very short period of time as it can damage the liver.

Turmeric can also damage your liver. Personally I take magnesium (nutrition geeks) helps keep me regular, as far as sleep goes- well I’ve woken up from a hot flash and and now here so….

Zanatdy · 07/04/2026 03:24

Yes I take loads, peri menopause is hitting me hard. One thing i’ve noticed and had compliments on since I started collagen is my skin is glowing (it is called glow up!.

Collagen
Vit D (taken daily since covid)
Turmeric (for bad hip)
Glucosamine (as above, hip)
Vit C
Vit B complex
Magnesium (sleep is terrible, don’t think they do anything)
Omega 3 (just started this week)
Biotin (came free with collagen powder).

I am rattling, and feel like crap. Starting HRT next week, hopefully that will help.

boydoggies · 06/04/2026 22:46

I tried collagen for as few months but didn't really notice any change.

I do take magnesium, ashwganda and lions mane. I do think it helps my overall sense of calm and focus.
I buy from nutrition geeks.

Please be aware that you should only take ashwagandha for a very short period of time as it can damage the liver.

TeaAndTattoos · 07/04/2026 03:14

I only take vitamin D I was told by my GP to take a daily maintenance dose after treatment for severely low vitamin D the main difference I have noticed is that my periods are regular and normal and no long hit and miss I also don’t feel as tired or in pain all the time.

Changeitbacktomorrow · 07/04/2026 02:56

Loads 🤣

I take 2000mg monolaurin every day. It’s from coconuts and a powerful natural antiviral, since taking it I hardly ever catch bugs that are going around, and if I do I get over them really quickly. My immune system used to be shockingly bad before I took it. I also never get cold sores now.

Also reishi mushroom - I have high blood pressure and am on meds for it, but at a low dose as with taking this supplement too it’s under control. My blood pressure does get higher if I don’t take it.

Magnesium for sleep - it does help.

Lions Mane - to help with perimenopausal brain fog. I have noticed a difference since taking it.

Boswellia serrata for my arthritic knees. This stuff is amazing, cheap as chips and I’ve gone from being in agony at the end of each day to literally no pain at all.

Hey Nutrition menopause complex. I swear by this stuff - it has really helped with my crankiness and lack of sex drive. I don’t take HRT as I am managing fine with this supplement.

Probiotic every day, not sure if this helps or not but I know having a healthy gut is important.

Multi vitamin and vegan omega 3-6-9 oils, because I’m a vegetarian and I’m sure my diet doesn’t always provide me with everything I need.

Shatandfattered · 07/04/2026 00:59

Vitamin d3k2 spray
B12 and biotin
Iron+
Magnesium
Inositol (d-chiro myo blend)
Creatine
Tumeric black pepper tablets
Probiotics

I have PCOS plus some unknown issues re very poor sleep hygiene, crunching joints for my whole life, exhaustion, low mood and motivation and poor cognitive health and I've religiously took these for months and have managed to consult with my doctor and get off sertraline from 250 tapered to 50 then stop. Don't feel physically well as of yet but mentally it's much clearer

namelesswench · 07/04/2026 00:53

Vitamin D through multi vitamin supplement. I had my blood work done 15 years ago and was severely defficient (thanks Scotland). Had it done a year ago or so and it is at 100%. I also take biotin which i think helps my hair/nails, but I can't be sure if it was that or having a child that caused my tiny brittle nails to start growing.

Magnalux · 07/04/2026 00:52

Anyone tried the sisterly woman’s multivitamin ? It a one stop shop for female multivitamins allegedly! I’m very tempted but it’s crazy expensive

It's a massive industry and the vast majority are not needed. Most are a waste of money at best.

I'd only take something if I had been diagnosed deficient based on testing at the doctors.

I have a friend who buys so much in Holland and Barrett I’m surprised she’s not invited to their staff xmas party!
she Buys into it all and spends a fortune! Does she look amazing? 10 years younger -
not really but she is happy!

dreamlove · 07/04/2026 00:31

Multi vitamin and omega 3 to cover anything I’m missing from diet
vitamin d as I’m deficient and work underground
iron as my iron saturation is low

TowerOfWashing · 07/04/2026 00:17

I think a lot of it is (over-priced) snake oil especially the menopausal supplements (have tried quite a few). HRT made the real difference for me.

However, I do believe the following are useful for me.

Vit D ( within a cod liver oil tablet) - low daylight levels where I live
Iron (I'm a poor absorber)
Creatine - I feel it definitely helps with brain fog.

I know a few folk who swear by magnesium for sleep but it does nothing for me. Again, HRT/mini pill had the biggest impact on this for me.

i do think the big corporate brands over charge for the vitamins etc

PrinceYakimov · 07/04/2026 00:03

Multivitamin and extra vitamin D and B12 on GP's recommendation. Has stopped extreme tiredness and my hair has started to regrow after partially falling out.

Fish oil omega 3 to help with dry eyes. Jury still out on this one.

Considering creatinine.

CaragianettE · 06/04/2026 22:52

I really doubt your iron level would change enough in a few days to make you feel different. Coming at it from the other end, if you are iron deficient I think advice is that it will take at least a week for you to start to feel benefit from iron tablets. So I just don’t think levels change that fast.

They do with Spatone as it's very easy to absorb as already dissolved in water.

I was on the verge of having a blood transfusion after a bad caesarian due to v low iron, they had me on iron tablets for 5 days with no result then a friend brought me spatone and after 3 sachets my levels shot up overnight.

Blood transfusion called off.

I've sworm by spatone ever since especially during and after a heavy period.

Notquitetheplan · 06/04/2026 23:49

Vit D on drs recommendation.
Iron with multivitamin - helps with postural hypotension
Glucosamine - helps with arthritic pain and inflammation.
Joined the collagen brigade a few months ago, not sure if it’s helping but as everything seems to be wearing out thought it couldn’t hurt!

chasegirl · 06/04/2026 23:44

Lions mane, vit d, collegen, turmeric and magnisium. Just started creatine so waiting to see about that 1. Don't think I could fit any more in 😂

Am 55. Fairly active. The magnisium definitely helps me sleep. Vit d levels are middle of normal range from last blood tests just before Xmas. Had a reasonably ok menopause (can't have hrt and think it could have been worse) so figured the rest must be doing something

BiteSizeByzantine · 06/04/2026 23:43

Vitamin D, its a must! It makes a huge difference to how i feel.
Spa tone. When I slack off from taking it I can really tell.
And I started collagen about 2 weeks ago, I was really sceptical about it, but I swear that my skin already looks better. I will keep taking it because I really can't taste it in my tea.
