High Strength Probiotics

High-count probiotic formulas, generally from 20 billion CFU upwards, for anyone who wants more than a daily maintenance dose - often after a course of antibiotics, or when a standard strength has not done much.

Biocare, Optibac and Solgar make up most of what we stock here. Optibac publishes the specific strains in each product rather than a blended total, which is the detail worth looking for. If you are buying for a child, the children’s range uses strains chosen for that age group instead.

We have sold probiotics since long before they reached the supermarket shelf, and the brands that last are the ones that are specific about what is in the capsule. Optibac names every strain and its count, so you can match a product to what you actually want rather than guessing from a headline number.

Biocare formulates in the UK alongside practitioners, and Solgar has been going since 1947. Between them they cover most of what people come in asking for, and we would rather stock three ranges we can explain than twenty we cannot.

CFU stands for colony forming units - roughly, how many live organisms are in a dose at the time of manufacture. Higher is not automatically better, and a well-chosen 10 billion product can suit someone better than a 50 billion one.

What matters more is which strains are in there and whether the count is guaranteed to the end of shelf life rather than only at the point of packing. The better brands state which they mean.

Some need refrigerating and some are shelf-stable; the pack is explicit, and we ship the chilled ones accordingly. Shelf-stable does not mean lower quality - it usually reflects the strain and how it has been freeze-dried.

Most people take them daily, and many prefer the morning. If you are taking antibiotics, the usual approach is to space the two a few hours apart and continue the probiotic after the course finishes.

FAQ

How many billion do I actually need?

For general daily use, 5 to 20 billion is a common range. Higher-count products tend to be chosen for shorter, more specific periods. If you are unsure, ring us on 01323 928523 - it is the sort of thing that is much easier over the phone.

Do they need to go in the fridge?

Only some. The label says clearly, and anything requiring refrigeration is packed for it when we send it out. If a chilled product has arrived warm, tell us and we will sort it.

Can I take one with antibiotics?

Many people do, spacing them a few hours apart and carrying on for a while afterwards. Your pharmacist can advise on timing against the specific antibiotic you have been given.

Are they suitable for vegans?

Plenty are, though some strains are grown on dairy-derived media and some capsules use gelatine. Vegan lines are marked and you can isolate them with the filters above.
