SNS Glycophase Is what I have been hearing is a solid one. I will be adding it myself in about 2 weeks.
Predator is good and more affordable
Primalog is expensive but excelent profile
Completely unbiased opinion as I own HPS and we make Glycøshield:
Predator: I love pterostilbene and am releasing it standalone or adding to Glycøshield. I have tested predator with BG meters and I don’t trust it for super carb heavy users. I have a bottle and will take 1 cap at bed some nights bc of the pterostilbene. Not really a fully disclosed label (Corsolic acid)
Glycophase: very cost effective, good profile, some users don’t like using the bitter melon daily as there’s been studies relating to infertility. I have used it and do support it as effective.
Primalog: see above for bitter melon and banaba/corsolic acid % extract also not disliked, and 7 capsule serving can be a big deterrent. I have used it and do support it as effective.
Glycøshield: the only gda on the market that uses 10% corsolic acid, fully discloses every single ingredient to % extract and uses GS4+ (75% gymnema/highest available) and Salaretin (both Sabinsa trademarks) all 6 ingredients at clinically studied doses. The only GDA that also emphasizes helping prevent excess FAT storage by including 50% hydroxycitric acid and 20% oleuropein olive leaf for thyroid and metabolism enhancement and anti inflammatory properties bc let’s face it, very few of us are downing 200g of carbs with NO dietary fat.... pizza, sushi, wings, ice cream, donuts.... the things we take GDA’s to eat all have carbs AND fat.... Glycøshield is really the only product that addresses both macros.
If you opt to use a different GDA other than Glycøshield I highly suggest adding in our Lipøshield which will help address dietary fat consumption/over consumption.
Our Innøslim also reduces absorption of carbs in the GI tract by up to 42% (available mid March)
Long story short those other GDA’s will work to an extent but those are also MASSIVE brands who focus heavily on bottom line=not necessarily the most effective raws. HPS is not my main source of income or full time job and the products reflect that as they are not formulated to make me rich. They are formulated to work 100% of the time and deliver exactly what we (myself included) all want—results.
To end this post on a fair note, if I had to pick a GDA other than Glycøshield to use daily, it would be glycophase bc I love berberine and glycophase packs a strong dose of it followed by predator bc of the pterostilbene. I’ll likely drop Glycøshield to 120 caps (from 180) and add in a moderate dose of pterostilbene due to this. Or just make a 50mg standalone pterostilbene @ 30 caps per bottle
