Really helpful mix of ingredients for protection!

I am a fan of clean eating and trying to keep a healthy distance from harmful toxins, but that is not always possible. I like the idea of a supplement with antioxidant properties to protect and support my body from what I’m exposed to all day. I’m pleased with the combination of ingredients, and especially the quantity of acai involved. One cap per day is a reasonable dose. They are easy to use, as expected. The brand is pretty well known and trusted. I recommend.

Great for the winter season

This is my first time trying a supplement from Synergy Holistics. So far all is good; the pills are average size and I find them easy to swallow with water. It comes in a twist cap bottle as shown in the listing pics.They have a slight herbal smell but nothing over powering. There's no after taste and no side effects after 2 weeks of daily use. The label says 1 capsule twice daily with food. This makes the bottle a 1 month supply.I haven't noticed any radical difference in my health nor am I expecting any but since its an antioxidant I will take it as a good sign.There's no requirement to refrigerate after opening.I like its combo of ingredients that I would not normally take individually, especially during these winter months, to help keep me healthy

No negative side effects to report

I have been taking for about half a month now, no negative side effects or clashing with my other holistic supplements. Everyone around me is also getting sick but I am yet to catch it, the pills most likely enhancing my immune system. Great antioxidant source, tested and made in Canada - huge plus.I hope you found my review helpful.

Good multi-antioxidant

I had already been taking a few of these supplements separately. While this is convenient, the dosing is on the low end compared to what I usually take. The bottle came properly sealed with good dating. It is also twice daily dosing, making it a one-month supply. The capsules are easy to swallow with no negative taste or effects.

Booster in winter to prevent respiratory issues

The company Synergy Holistics offers unflavored supplements. The product is a powerful NRF2 antioxidant supplement composed of transresveratrol, quercetin, grape seed extract and pomegranate. It promotes respiratory health. With Quebec winters, respiratory viruses are common. This supplement can help maintain better overall health.The product is safe because they are manufactured in GMP (good manufacturing practices) certified facilities. The capsules are gluten free and vegan which can make a difference for someone with allergies.The company states that it should not be used if you are pregnant or breastfeeding. In addition, if you take medication in your daily life, it is recommended to talk to your doctor about the product before using it. It could have contradictory effects which you don't want to happen.The effect is not yet seen, but I suppose that by taking them on a regular basis, I will start to notice changes. Overall, I think it might just help me.The price is currently discounted to $27 for 60 tablets which amounts to $0.45 each. Normally, the price is $30 which amounts to $0.5 per tablet.The company mentions that it is recommended to take it twice a day which means that one bottle lasts 1 month.

Synergy Holistics - Radical Defense Synergy

It is not possible to objectively evaluate the benefits or the efficacy of supplements through ordinary home use; so, I will not get into this product's effectiveness, and you can search the Internet for the benefits of the main ingredients of this product.It is clearly indicated on the bottle that it was manufactured in Canada, and it has an NPN number (Natural Product Number) that can be used to confirm that it was licensed in March 2014, and the license was revised in October 2024. There are 5 brand names associated with the license, and the license holder is Optimum Health Vitamins & More.Similar to the label on the product, the NPN product information page lists 6 medicinal ingredients. Risk information on the NPN page is as follows:"Cautions and WarningsIf you are taking prescription medication, consult a healthcare practitioner prior to use as resveratrol may alter the effectiveness of these medication.Contra-IndicationsDo not use if you are pregnant or breastfeeding.Known Adverse ReactionsHypersensitivity/allergy has been known to occur to acai or plants of the Arecaeae family. In such a case, discontinue use."It comes in a container with 60 capsules in it. The recommended dosage is 1 capsule, twice daily, with food, which should have the bottle last for a month if you follow the recommended dosage. The price was $30 CAD at the time of writing.While I cannot confirm the claimed benefits or the product's efficacy, I see no reason to cut any stars from my rating. I appreciate that it was made in Canada and that it comes with a proper NPN number on the bottle.

A blend of anti-oxidants, no need for several bottles

I’m happy to try out Radical Defense Synergy. I like that it is a combination of resveratrol, quercetin and grape seed extract. These are known to have anti-oxidant and anti-inflammatory benefits.This is a quality product made in Canada. Price is fair for one-month supply. Just one small thing - dosage is 2 per day but perhaps 1 per day would be easier especially when it's necessary to take other supplements or medicine on a daily basis.Things I like:- Product of Canada.- NPN number to indicate the product has been authorized for sale in Canada.- Triple tested. GMP-certified.- Non-GMO, dairy free, gluten free, soy free. No artificial colors, flavors, or preservatives.- Bottle is properly protection sealed.- Long expiration date Mar 2027.

Excellent

I am taking these capsules for health support, this winter I got hit with a few seasonal respiratory illnesses and I feel better taking these.The supplement is a combo of various extracts, such as resveratrol, nettle, pomegranate , grape seed and other, most of which I have taken separately in the past. As expected I had no ill side effects, I enjoy taking them to improve my immune function.I really like the concept and the realization of this supplement, the fact that it is Canadian made and it has all certificates and NPN in order.The labels are hard to read, now it’s true that a lot of information is printed on a very small space.I like thisThank you

nice Canadian product

I was happy to try this out to see if it helps with some of my concerns. It's too soon to be certain yet, it takes a while for natural things to cumulate enough to really show improvements.I find the capsules easy to swallow and have had no side effects at all. I appreciate that this is an all natural product and that it's Canadian made

great combo

I would give this 4.5 stars if possible. Great product from a great company. I find the entire line from Synergy Holistics very beneficial and powerful. Its seems to come at a bit of a premium price however. I don't see any mention of 3rd party testing which is unfortunate. Between that and the premium price I can't give it a full 5 stars.

Good mix of antioxidants

This radical defence synergy supplement contains a number of antioxidant supplements such as resveratrol, quercetin, nettle, acai, grape speed and pomegranate extract. I use this every winter to help boost my immune system during cold and flu season. The dosage is one capsule twice per day and each bottle is a 30 day supply. I only take supplements once per day so I have been using these once daily. One thing to keep in mind is that there is low dosage of all the supplements, despite having 6 supplements in one. For example, I normally take a 500 mg dosage of quercetin daily, but two capsules of this supplement only contain 200 mg of quercetin. It’s a great way to take a variety of different products in one capsule but each capsule doesn’t contain a lot of any type of supplement. Overall, I’ve been happy with taking a low dose mix of various supplements and will likely repurchase after I’m done with this bottle.

No benefit or negative side effects noticed from taking them

These have a sort of dried herb or day-old dried cut grass smell to them in the bottle but they go down easy with a glass of water and have no noticeable taste. I'm not sure if the benefits of taking this supplement are only apparent after long term cumulative use or they are internal benefits you can't discern because they occur at a cellular level. I haven't noticed any change, either improvement or detriment, in taking them though. I didn't have any allergic reaction in taking them or have any symptoms of hypersensitivity that the package label warns against as a potential side effect of taking them.Results will vary from person to person I'm sure like most supplements.

My Honest Reviews
Protect, Renew, Preserve

These gel caps are an antioxidant supplement of four proven herbal supplements: nettle, pomegranate, acai, grapeseed and resveratrol. Regular, daily use as directed strengthens the immune system and feeds the skin from the inside out. There are 60 caps in a bottle with a recommended dose of two per day. This is a water soluble supplement, so perfect to crack your capsule into your morning smoothie or juice. I'm giving this product four stars because labels need to be legible and 1 pt font is not okay, especially when you consider the target market for this supplement is in the neighbourhood of Gen X - Boomerville. Otherwise, this is a well-thought out product with four proven antioxidants. Buy with confidence.

A great combination supplement to help your immune system

I have been taking some other Synergy Holistics supplements which have given me good results. In my experience this is a trusted brand, manufactured in Canada at a GMP-certified facility, rigorously tested for stability and potency before, during, and after production.I have a weakened immune system due to a chronic health condition so the combination of resveratrol, quercetin, grape seed extract, and pomegranate are a blend of powerful antioxidants known for their immune-boosting and anti-inflammatory benefits. I have been taking this supplement for a month and have had no winter colds or flues. The twice-daily dosage means I am getting a steady intake of beneficial compounds. At around $1 per day, the price is reasonable for a supplement of this quality. Plus it's a great way to get multiple beneficial ingredients without buying them individually.This supplement is free from artificial colors, flavors, preservatives, wheat, gluten, corn, yeast, dairy, soy, and non-GMO. I like the face that Synergy Holistics products are crafted as pure as they come.I'm also pleased to be supporting a local Canadian manufacturing facility. I highly recommend it!
