Benefits of The Strength Stack

  • Shilajit supports steady, natural energy throughout the day, helping you stay active and feel your best.

  • HMB, Vitamin D3, K2, and Calcium work together to help protect lean muscle and support strength and recovery, so you train hard and bounce back faster.

  • "I noticed a considerable improvement in the quality of my sleep from the first night. Falling asleep became easier, and I slept deeper and more soundly throughout the night. Since using this supplement, I've woken up feeling refreshed and energized on a regular basis.

    In terms of dosage, this brand offers 100 mg in small capsules, which is the recommended dose for apigenin. I find it to be effective for me. Highly recommended."

    Emily N.

  • "I have struggled with insomnia for a couple months.. waking up after 3-4 hours and being unable to get back to sleep. Melatonin helped a bit/sometimes. Diphenhydramine HCL knocked me out, but I was a zombie the first half of the next day. This apigenin worked immediately! If I do wake up, I can still fall back asleep and feel great the next day. Now I can sleep longer and much better."

    Don R.

  • "I prefer using simple, non-toxic herbal and naturopathic remedies above any prescription medicines. I found apigenin by accident. Although I've long known about chamomile's calming effect, I did not know of the extract. I am happily surprised to know about this supplement, and it indeed helped me to get more restful sleep."

Have a question? Ask Boscent.

What are Shilajit, HMB + D3 + K2, and Apigenin, and how do they work?

Together, these three actives form the Strength Stack: fuel, build, and recover.

Shilajit is a natural mineral resin, long valued for supporting steady, natural energy so you show up ready to train.

HMB + D3 + K2 works to help protect lean muscle and support strength and recovery, while K2 helps direct calcium to your bones, the structural foundation strength is built on.

Apigenin is a natural bioflavonoid found in plants like chamomile, valued for its calming properties. It works with the body's own relaxation pathways to support stress relief and higher-quality sleep, so you recover overnight.

How should I take Boscent's Shilajit, HMB + D3 + K2, and Apigenin?

Each supplement in the Strength Stack works best at a different point in your day:

Shilajit — Take one (1) capsule two (2) times a daily, with water.

HMB + D3 + K2 — Take one (1) capsule four (4) times a daily, with water.

Apigenin — As a sleep supplement, take one (1) capsule 30–60 minutes before bed, with water.

When can I expect to see results?

Individual responses vary. Some benefits, like calmer, higher-quality sleep from Apigenin, can be noticed within the first few days. Others, like steady energy and muscle and recovery support, build gradually over several weeks of consistent use. For best results, take each supplement daily as directed.

Are there any side effects associated with Shilajit, HMB + D3 + K2, and Apigenin?

Each ingredient in the Strength Stack is generally well-tolerated when taken as directed. As with any supplement, individual reactions may differ. If you are pregnant, nursing, or taking medication, consult a healthcare professional before use. If you notice any adverse effects, discontinue use and consult a healthcare professional.

Can I take Shilajit, HMB + D3 + K2, and Apigenin with other supplements?

In most cases, yes. The Strength Stack is designed to fit into a daily supplement routine. If you take prescription medications or have a health condition, consult a healthcare professional before combining it with other products. They can offer guidance based on your individual health profile.

Are Shilajit, HMB + D3 + K2, and Apigenin suitable for vegetarians or vegans?

Yes. All three formulas are made with plant-based capsules and contain no animal-derived ingredients, making the Strength Stack suitable for both vegetarians and vegans.

Can pregnant or breastfeeding women use Shilajit, HMB + D3 + K2, and Apigenin?

If you are pregnant or breastfeeding, consult your healthcare provider before using the Strength Stack or any new supplement. They can advise on what's right for you at this stage.

Are Shilajit, HMB + D3 + K2, and Apigenin tested for quality and safety?

Yes. Every Boscent product is third-party tested for purity and safety, including screening for heavy metals, and made to strict quality standards. It's the standard we hold every batch to.

How do I use the Strength Stack?

The Strength Stack is simple to work into your day: Shilajit for morning energy, HMB + D3 + K2 to support muscle and recovery around training, and Apigenin in the evening for restful sleep. Take each as directed on its label.

How can I trust Boscent quality?

Every Boscent product is made in a GMP-certified facility and third-party tested for purity and safety. We publish a Certificate of Analysis for each product, so you never have to take our word for it. You can see the proof for yourself.

Will my products expire?

Every bottle is stamped with a unique lot number and expiration date. For best results, use your product within one year of opening or before the printed expiration date, whichever comes first. Because our formulas are free from added preservatives, potency is at its peak when used fresh.
