Biom Virus Shield

Biom Virus Shield has a great name, and on first glance, looks like a great product. It does contain several key ingredients namely Elderberry and Echinacea plus a host of patented ingredients which can usually be a good sign that you are looking at a good product. However, when we started to pick them apart we could not ascertain the exact amounts of each ingredient as they are grouped together in patented proprietary blends which makes it super hard to understand exactly how much of something you are ingesting. 

This was not our only concern. When reviewing this product, we were shocked to see that it came with a price tag of almost $100! This is absurd. It may be a mistake on Amazon but if not, a one-month supply of this product would leave most people broke! It is definitely not what we would class as an affordable option for the majority.  We appreciated the fact they based their formula upon a variety of patented ingredients but don’t like that a huge chunk of this product is made up of probiotics. Whilst probiotics are super important for maintaining gut health (poor GI health is of course a symptom of a weakened immune system), it is not the most essential. We would like to have seen a separate probiotic product alongside this Immune Boosting formula for the best results. Unfortunately, we felt that they were simply lacking in more of the key ingredients that are backed by scientific research. 

We also didn’t find many positive reviews, which was a shame, but the one that we did find was singing its praises which was good to see. This is a fairly new manufacturer so we don’t know so much about them but what we do know is that they don’t offer a money back guarantee, which is really quite disappointing.

Legion Immune

Legion Immune is a product designed with adults in mind and offers a high dosage of Vitamin C in its formula, alongside other key ingredients Garlic and Zinc which for us, is a great start. However, they failed to include the clinically proven ingredients Elderberry and Echinacea instead substituting them for Geranium, Ginseng and Polysaccharides. Whilst these are healthy ingredients and we have no doubt are top quality, they are not the most effective for boosting your immune system. This was disappointing to say the least.   

We liked the fact that this product contains a large serving of Vitamin C (almost 500 mg) but we really feel that this is perhaps a little high when the RDA falls around 100 mg. Why include five times more than the RDA? We know for sure that this is not based on any research that we have found – could it be that they know something that we don’t? However, we did like the price. At $39.95, this seems to be on par with other similar products and falls within something that is affordable for most people. 

Most impressive were the positive reviews we found on Amazon about how well the product has worked for people. That said, there were not that many which leaves us questioning how new to the market this product is and how good it really is. We could not find an effective money back guarantee which is always a red flag for us. In addition, we were unable to find any real clinical studies that support the ingredients that they have included in their formula.
