  • How can a probiotic support my immune system? What's the link between gut health and my immune system?

    Your gut wall houses 70% (some say as much as 80%) of the cells that make up your immune system. With such a direct connection, your immune system will be heavily impacted by the health of your gut.
  • Why is vitamin D so important? Why is it important to take it in supplement form?

    Vitamin D3 offers many well-known health benefits. It is known to help strengthen bones and muscles, support the immune function, increase mood, aid in weight loss, and improve heart function. Your skin naturally produces vitamin D in response to sunlight or ultraviolet light. However, during the darker months of the year October-April, we are advised to supplement our Vitamin D. Adults over the age of 65 are encouraged to supplement with vitamin D year-round.
  • Your probiotic supplement contains Vitamin D3? Is vitamin D3 better than D2?

    Vitamin D3 appears to be more effective at increasing levels of vitamin D in the blood when compared to vitamin D2.
  • Is your Vitamin D3 in your probiotic supplement vegan?

    Yes, our vitamin D3 comes from a plant-based algae source.

I've taken this all winter and I'm going to continue taking it. Not one winter cold or flu this year.

I'm so glad you increased your vitamin D. That was only negative about this product but not thats corrected. Good thing I only learned that you increased your vit D from watching Lily on your FB.

Della | 2020-12-07 10:40:58

This product is so good. You probably don't want to hear this but I feel better just knowing I'm taking it. I was recommended the product for the Vitamin D.

Keitha Monroe | 2020-11-25 12:56:05

I've been taking this product for 2 years now and I was pleasantly surprised to see you've increased the Vitamin D levels. When did that happen?

Fran | 2020-08-25 08:59:33

Brilliant concept to include the vitamin D. It helped me through last winter for sure. I'm hoping it will do the same this year, more than ever. Do you do a subscription so I don't need to keep reordering it?

Jason | 2020-05-22 08:32:06

I almost didn't write this review because I didn't notice anything until I realised I didn't have my 'usual' February/March cold this year. Thats really something for me. I always get a winter lurgee.

Really good product. I like that it contains Vitamin D but I prefer your Bioharmony Balance.
