This is my second round on these supplements and I even got my father to take them. I used to take only D3 and K2 but I decided to go for something more and after a lot of research into different brands and ingredients I have to say this one made the most impact and this is why.
I've had countless injuries on both my knees, my right ankle and my wrists (football, basketball, tennis, sprints, bjj and boxing). Overtime, I felt like I was always injured or bound to be injured. Of course paired with more smart exercising and recovery session the joint and bone supplement hit the nail on the head. I feel no more pain and I take risks more without being scared of injury. Yet to find out how it impacts my dad.
I have had back pain for decades, I have had many physios review my case, osteopaths, chiropractors, acupuncturists, MRI scans, X rays, several pain clinics - most of whom were certain they could solve my problems. Older and poorer I finally came to Health by Science and Yasemin. I now have hope that there could be an end to my constant pain. Yasemin listens and works out exercises just for me, she checks on progress and is anxious not to push too fast but to consolidate on what works. She even takes her class outside when the sun shines! Yasemin keeps it interesting and is so enthusiastic. I can't recommend it highly enough.
I love your products! My skin, nails and hair have improved - much stronger - and my knees have stopped clicking!
I fee generally much better than before and my husband also takes them and his skin has improved too. Thank you for a brilliant product 😃
I found this item and I’m glad I did as it’s completely vegan and I used to have another range which wasn’t so good
Took these for 3.5 weeks and sadly they seem to be making my symptoms worse. Tried reducing dosage but still didn't have a positive effect. Also tried reaching out to Positive Science People for advice/support as their emails suggest you can contact them with any questions but never got a response. Disappointing.

Ive been using this for over 2 months now so this gives me enough perspective to say, I love it!
I started seeing a difference in my skin after 3 weeks. But I wasn't sure if I'm imagining things. However, when people started telling me how good and radiant my skin looked, and did so unprompted (!), I realised it's not in my head. My skin before was dull and slightly blotchy, and it is now clearer, plumper and radiant. I think even my hair is less unruly.
This is superior to the previous vegan collagen powder I've used, and much cheaper and the service is terrific.
I recommend you give it a try for two months and see for yourself.

I have been taking Actiflex for over 2 years and I wouldn’t be without them. Osteoarthritis game changer. All the minerals vitamins etc etc in 4 capsules daily.
Excellent products, excellent service!
I have already subscribed to their Collavegan and now trying out their EnergyRelease, which seems equally efficient.
On my 2nd month and I feel like I have more energy. Before taking the supplement I was struggling with fatigue, which in turn affected my running, excercise, work etc. I Feel more focused. So far so good, I'm really pleased.
I've been using the collagen supplements for over 2 months and can see a noticeable difference with new hair and nail growth. I love that they also do not taste of anything and are so easy to take.
I've been taking the Collavegan capsules for two months now. I've started to notice a real difference in my nails. They're growing faster and have fewer ridges. After having just recovered from a nasty illness, I'm hoping looking forward to more changes in skin and hair as well.
I have been taking this collagen for 5 months and am very happy with my subscription and will continue to take it. Finally, I found a vegan collagen that works❣️
The collavegan arrived promptly,& my hair skin & nails have shown an improvement in the first month.Im 71,what's not to like,especially at my age.

First time using Positive Science People. Easy to order, and prompt delivery of my Vegan product. Competitively priced product and a first time order incentive, which is always welcome. I will definitely be ordering again and would recommend to friends and family.
The joint supplement has been wonderful. It has relieved my residual pain from an old frozen shoulder after 2 months of use. My sore hip is feeling better after 4 months of use. Quick delivery. Great product and great customer service.
